teams darwin and charli from the robotics and mechanisms laboratory ( romela ) are the first u . s . groups to win the adult - size and kid - size classes , taking home bragging rights along with the louis vuitton humanoid cup , a prestigious crystal trophy that was held by germany and japan in the past .
if the darwin family of robots increases the number of students majoring in computer science and engineering , even as it helps us design humanoid robots that better embody the capabilities of human beings , then all of our goals will be met . together , we are creating a truly exciting enabling infrastructure for humanoid research , education and outreach .
the university of manitoba ' s 2014 entry in the icra darwin - op humanoid application challenge , featuring jeff on the bicycle . following on our last two presentations ( see below for links ) we continue to look at novel applications for humanoid balancing . this year we are looking at the problem of riding a bicycle . the robot uses inverse kinematics to calculate the positions of its arms and legs to allow it to pedal and steer . because the hands must remain on the handlebar and the feet are in constant motion we have very minimal degrees of freedom available for balancing . recorded at the university of manitoba ' s autonomous agents laboratory , march 2014 . music :

the framework that the team proposed for the competition provides a case - based reasoning approach to robot learning , a human reasoning methodology that retrieves the solutions of problems observed in the past , and reuses the solutions to respond to emerging similar problems . researchers using the framework can model their own task as tablet apps and configure the framework settings to teach the task to their robots . the framework provides tools for modeling the task policy through training the parameters for case - retrieval function that maximizes the rewards . during the demonstration , the team’s robot , angry darwin , was able to quickly learn the strategies to solve each level of angry birds after less than three or four demonstrations from the teacher . angry darwin not only learns to play the game , but also picks up verbal and emotional behaviors that the human teacher demonstrates . the robot then converts the learned emotions into his own verbal and gestural primitives that merge with his task behavior . the team anticipates using angry darwin as a mediator to research how social interaction emerges during human - robot interaction .
what really makes the difference is the advanced computational power of robotis op2 : 4 times more ram memory , a 32 gb storage capacity versus 4 gb for the previous version , extra fast data transfer , and support for all linux and windows ( 32 - bit ) products while robotis op could only communicate with linux . rest assured , robotis keeps improving its little man via an open platform , both in terms of software and hardware !
the first part of my summer research project . i can control the steps darwin makes on my dance pad . the next step is incorporating vision . edit : i ' m an undergrad at purdue university and my summer research project is an reu funded by nsf . thanks to professor lu , professor lee and professor koh . thanks to the grad students in the lab andy park and rami alazrai .
our experience using the darwin under competition conditions gave us insight into the limitations of the stock framework and ideas on how to improve it . specifically , the built - in vision system was very primitive and ill - suited for the rigors of competition , there was no forward - or inverse - kinematics modules to control the motion of the limbs in three - dimensional space , and the build scripts were not designed with a standard linux file structure in mind .
at the moment , darwin relies on a balancing bar for stability and to enable faster moves , but you hardcore ddr players should be familiar with the safety bar on the arcade machines that could be used ( by crafty humans ) for essentially the same purpose . in the works is tuning the robot ' s vision system to allow it to play ddr for real , and bar - free stability may come after that . is anyone else thinking that robot ddr would make a great new robogames event ? no ? just me ? oh .
in this paper a new robot is presented which was designed especially for robocup soccer . it is an approach to evolve from the standard darwin based skeleton towards a robot with more human motion capabilities . many new features were added to the robot to adapt it for the special requirements of robocup soccer . therefore , the interaction possibilities with the robot were improved and it has now more degrees of freedom to easier grip a ball and balance itself while walking . the design is open source , thus allowing other teams to easily use it and to encourage further development . furthermore , nearly all parts can be produced with a standard 3d printer .
dr . howard and her students are affiliated with the school of electrical and computer engineering ( ece ) at georgia tech . their team , dubbed as “angry darwin : framework for human - robot task collaboration on a shared tablet workspace , ” demonstrated their robot learning from a human demonstrator how to play a game of angry birds . based on ms . park’s ph . d . thesis work , “task learning policies for collaborative task solving in human - robot interaction , ” the key elements to long - term engagement during human - robot interaction are the robot’s capability to learn and engage in new tasks through human demonstration and a defined workspace that provides content that both the human and robot participants can use and enjoy .
the darwin series of humanoid robots started in 2004 and has evolved through four generations . it was the very first humanoid platform from the usa to qualify for competition at robocup and has been on at least three magazine covers . about two years ago , we started to receive a growing number of requests from research laboratories and universities who wanted to use this kind of research humanoid platform for research , education and outreach activities . based on this growing interest , we wrote an nsf research and development proposal that was approved and funded , and this then became a serious r & d project for romela and our partners . ultimately , the humanoid robotics research and educational community across our nation and world are sure to grow , owing to this fantastic new platform .

this is the fifth humanoid application challenge and we are proud to have won first or second / finalist prize in this competition every year it has been run . some of our previous first - prize work was the skating and skiing work you can read about in previous stories on the lab website . while we are exceptionally proud of all of our competition wins , the humanoid application challenge is unique in that its awards are robotics equipment , which directly supports further research work in the lab . the first prize awarded this year is a darwin op3 humanoid robot ( valued at around $ 13 , 000 ) , which will join our collection of darwins that we use for the small - size humanoid work in the lab . this is an incredibly useful addition , and we thank robotis for sponsoring the prize , and iros for travel funding .

in the not - too - distant future , your afterwork routine might go something like this : walk in the door . note that a robot is vacuuming the living room while another is washing the kitchen floor and another is folding laundry . your robot butler slides into view . after a quick update on the day ' s events , it asks what you want for dinner and cues up your favorite music .
of course this scenario has been in the not - too - distant future for decades , well before tv ' s jetsons and their robot maid , rosie , were the rage of 1962 . it has never been practical , particularly in the u . s . , which tends to be skeptical of personal robots . but a flurry of factors , including the rise of open - source robotics , increased government support and media - savvy evangelists are bringing the
autonomous home
closer to reality .
the face of this latest robot revolution is dennis hong , a mechanical engineering professor from virginia polytechnic institute & state university . hong ' s romela ( robotics & mechanisms laboratory ) research lab has developed 20 kinds of robots over the past seven years . they resemble everything from snakes to spiders to iron man . hong , who performs magic as a hobby , is a natural showman . armed with his robot props and videoclips , he thrills audiences with creatures that crawl over rocky terrain , scale poles , type on keyboards , introduce themselves and play soccer . hong has won invitations to appear at the ted conference , new york ' s american museum of natural history and on the discovery channel .
a few years ago hong ' s ambition to humanize robots might have been dismissed . following the emergence of the first commercially successful robots in the 1960s and 1970s , government support dwindled . the computing components needed to create rosie - type robots weren ' t available . every external research proposal hong wrote during his first two years at virginia tech got rejected .
then came a 2006 national science foundation - sponsored study that declared the u . s . embarrassingly behind asia in humanoid robots . since then hong has amassed $ 5 million in grants from the defense advanced research projects agency ( darpa ) , nsf and office of naval research .
demographic shifts are playing a role , too . colin angle , chief executive of irobot , the maker of the roomba vacuuming robot , expects robotics to eventually become a
triple - digit billion - dollar
business , in part because of the growing need for affordable , in - home health care .
this is an industry on the move . increasingly important business plans , ideas and concepts are being tested out ,
says angle .
in a break from earlier robotics , much of this testing is taking place on open - source hardware and software so more innovators can play a role . irobot designed ava , a customizable robot with a tablet computer
head
and a wheeled - column body , to serve as a development platform for robotics , like linux for computers .
ava ' s
brain
consists of either a google android tablet or an ipad . angle , who sees potential for home security and medical reminder apps , as well as downloadable personalities , says ,
a huge community could create apps that add utility to ava .
ava will join pr2 , a human - size robot that silicon valley company willow garage introduced in 2010 . the dual - armed , wheeled pr2 is powered by ros , an open - source robot operating system willow garage has distributed free since 2007 . the closely held firm has donated 11 pr2s to institutions around the world and sold 5 , and wants to encourage app development . one early program from uc , berkeley taught the robot to fold socks and towels .
willow garage chief executive steve cousins sees a parallel to the early days of the pc industry .
in the late 1970s you had the homebrew computer club ,
he says .
today it ' s the homebrew robotics club .
future pr2s could be employed in service industries and home health care .
hong ' s lab in virginia recently designed an 18 - inch - tall humanoid that can be built in a few days with standard parts , including a 1 . 6 gigahertz intel atom processor , gyroscope and accelerometer for stabilization and 2 - megapixel camera for object recognition . a ready - made version costs $ 12 , 000 , a bargain compared with the fortunes typically spent on research robots . ( willow garage ' s pr2 costs $ 280 , 000 to $ 400 , 000 . )
romela ' s bigger bot , the 5 - foot - tall charli ( cognitive humanoid autonomous robot with learning intelligence ) is a stylistic mix of iron man and the sleek
ns - 5
bots from sci - fi ' s i , robot . when charli took its initial steps last march it was hailed as the u . s . ' first untethered full - size walking humanoid robot . lighter , safer and more affordable versions are underway that will be suited for housework and caring for the elderly and disabled .


rudge whitworth cycles was a british bicycle , bicycle saddle , motorcycle and sports car wheel manufacturer that resulted from the merger of two bicycle manufacturers in 1894 , whitworth cycle co of birmingham , founded by charles henry pugh ( 1840 – 1901 ) and his two sons charles vernon and john , and rudge cycle co of coventry ( which descended from a bicycle company founded by daniel rudge of wolverhampton ) .

their sales motto was " rudge it , do not trudge it . "

the company also produced the first detachable wire wheel in 1907 , and was known for its knockoff wheels on sports cars well into the 1960s .

a little - known fact ( that ties in with the history of cyclemaster ) is that after rudge whitworth fell on hard times in the great depression , the music company emi bought the rudge name . emi produced bicycles under the rudge name from 1935 until 1943 when they sold the name to raleigh .
by 1878 rudge was established as a manufacturer of high quality bicycles . never satisfied with other makers’ designs and construction rudge invented numerous innovations . in 1878 rudge took out british patent no 526 for his adjustable ball bearings .
1943 raleigh bought the whole of the issued share capital of rudge - whitworth ltd [ 15 ] , after which the name was used on a bicycle range for some time .

rudge whitworth was formed in 1895 with the amalgamation of rudge of coventry and whitworth of birmingham , both bicycle companes . they began motorcycle manufacture in 1911 and went into liquidation in 1933 . they continued trading under the auspices of the gramophone company ( which later became hmv and then emi ) after moving to middlesex , and ceased trading at the onset of wwii with the last machines being produced by norman .
a history of the rudge - whitworth cycle and motorcycle company , from the late 1800s to the 1940s , including full production histories of the motorcycle models . topics covered include : the origins of rudge - whitworth , from daniel rudge ' s early bicycles , to the pugh family merger ; the expansion into motorcycle production in 1909 , with the ' m ' prototypes and ' f ' - head engines ; the invention of the rudge multi gear engine in 1912 , and a subsequent isle of man win in 1914 ; the innovative ' rudge four ' engines , with four parallel valves per cylinder ; the ' python ' models - rudge equipment used by other manufacturers , including in enzo ferrari ' s scuderia ferrari , and finally the post - war slump and a move to emi , with later attempts to revive the rudge name .
because nothing on a rudge - whitworth bicycle of this era can be installed from another manufacturer , when you come across one of these bikes now , over a century later , it’s important to ensure that the bicycle is complete and retains all its original parts . luckily , this one is original . i particularly like the rudge - whitworth ‘hand’ logo that appears on the oilers for the front hub and bottom bracket .

daniel rudge visited the famous french cyclist terront in his london hotel while on a visit to england . rudge proceeded to demonstrate to terront a set of his patent adjustable ball bearings . terront was impressed enough to purchase a racing machine built by rudge . daniel rudge also travelled to paris and lyons to observe the french cycling scene and to take part in some of the races .
a company that made their own components was at a considerable advantage , as quality control was easier to guarantee . in 1893 , with increasing demand for their bicycles , whitworth became a limited company and had to look for larger premises . the takeover of rudge the following year was a logical progression , with the pugh family providing the necessary management structure to see the combined company of rudge - whitworth develop into one of great britain’s leading manufacturers of bicycles and motorcycles .

rudge cycle sales remained excellent for several months after his death , but there was nobody to run the company . so walter phillips helped rudge’s widow mary to sell the company to george woodcock of coventry . woodcock thus acquired the famous adjustable ball bearing patent 526 and the services of some of rudge’s former employees .

whatever the truth of these two incidents , the essentials are correct . rudge - whitworth , riley and the goodyear wheel company were all involved in prolonged legal wranglings as to who owned the intellectual rights to the detachable wheel , right up until the outbreak of hostilities in 1914 . in fact the great war intervened in more ways than one . once it was over , riley considered there were bigger fish to fry and withdrew from wheel manufacture , despite having supplied a remarkable 183 car makers worldwide by 1912 . rudge - whitworth continued .
daniel rudge was approached about manufacturing a velocipede designed by phillips . a deal was struck and rudge was soon producing cycles in a small workshop located at the rear of the tiger inn , with henry clarke supplying the wheels .

rudge built python engines which they supplied to numerous other manufacturers including durandal , eysink , grindlay - peerless and imperia .
although rudge took over manufacture of the coventry rotary from starley & sutton from 1885 , the name coventry rotary was retained through to 1892 in rudge catalogues , when production ceased . the triplet tandem quadricycle direct steering roadster was produced from 1888 .
in 1929 graham walker won the ulster grand prix averaging over 80mph . this prompted the release of the rudge ulster , as well as a jap engined 250cc and parallel 4 valve 350cc . the rudge ulster was one of their most famous models .

[
if it sounds a precarious arrangement , competition proved otherwise . at the 1908 tt race , 21 of the 35 entrants used rudge - whitworth wheels , and only one of the finishers didn ' t by 1913 , the use of detachable ( rudge and riley ) wire wheels was universal in grands prix , and they were widely employed immediately after wwi on such lsr contenders as henry segrave ' s sunbeam tiger and parry thomas ' s 1926 babs .

however , the rudge - whitworth no 3 road racer you see here is a very interesting model . although it’s an upsloper of the old style , it already has a few features that herald the new designs of the following year : the pedals are conventional screw - fit rather than slotted cranks , and the seat post is of a wider diameter , the same as post - 1900 machines . it would appear that rudge - whitworth , with agencies in the major capitals , good sales results and innovative design personnel , was in a good position to capitalize on the new inventions and introduce them immediately to their bicycles , even before the end of the 1895 sales year .

this 1895 rudge - whitworth is a remarkably well - preserved example . transfers ( decals ) are made of gilt and very delicate so it’s very rare for a bicycle of this era to retain them intact . although they are faded , the headstock transfer ( top of the page ) and the top tube transfer with its model name ‘the rudge’ are still readable . the shop transfer , below , is harder to transcribe , but it can be seen that it is from a french cycle agency .

the rudge guarantee states that ‘the bicycle is guaranteed as long as it is ridden’ and ‘the guarantee goes with the bicycle – even if it changes hands . ’
rudge was a skilled engineer who became interested in bicycles through his friend walter phillips who rode bicycles and henry clarke who in 1868 began the cogent cycle company .
by 1878 , the company was based in bishop street with 100 employees . unfortunately , increased company responsibility plus various other cycle activities had a detrimental effect on rudge’s health . in the early summer of 1880 daniel rudge fell ill for the last time and died on 26th june 1880 of cancer at the age of 39 .
engine was added to the rudge frame to produce the rudge / jap dirt track machine in 1930 , production of this speedway machine was short term and the was stopped around 1933 , although they were used for a number of years after that for both speedway and grasstrack , there are some good examples around to this day .

competition , however , was sharp and there was a continual movement of small firms in and out of the industry . a few well - managed firms , however , like singer , the coventry machinists , rudge , and the premier grew steadily , organizing sales and installing capital equipment in the shape of new machinery . ( fn . 200 ) most striking was the development of the rudge company , an amalgamation in 1880 of the tangent and coventry tricycle company ( established in 1879 by george woodcock who bought the works of haynes and jefferies ) with the wolverhampton firm of dan rudge . the rudge works were transferred to coventry . expansion of the firm ' s trade followed from the increase of capital in 1885 when woodcock was joined by several birmingham men in a limited company , d . rudge and company .

in the original rudge - whitworth design , the male taper was on the wheel and the female taper on the nut , so the car ' s left - hand wheels required a right - hand thread and vice versa . on wheels where the male taper is on the spinner ( such as those fitted decades later to special equipment versions of the original lotus elan ) the thread sense is reversed .

let ' s now move onto a look at the rudge - whitworth system of wire wheels . this design was invented over 50 years ago and the car makers in great britain used this same principle until 1988 ; with this seemingly simple design , cars around the world have traveled countless miles in a sporting fashion . with the finishing of manufacture by dunlop of this type of wheel , preservation is now left to classic and antique car buffs .
legend has it that the centrelock wheel — originally known as the qd ( quickly detachable ) wheel — came into being as a result of two coventry men sharing a car one day during the early 1900s . one of them was john pugh , whose father charles had established the whitworth cycle co in 1891 and three years later rescued the ailing rudge cycle co to form rudgewhitworth ltd . the other was victor riley of the rival riley cycle co .
well written and easy to follow it is a must for rudge fans and anybody who just wants to understand why these machines are still sought after and command such high premiums .
amazingly , the rudge - whitworth wheel was originally sold as what today we ' d call an aftermarket fitment . automobile tyres were in their infancy in the early years of last century and tediously puncture - prone , so being able to repair a flat tyre quickly was important . pugh ' s centre - lock wheel was fast to remove and replace but , like the riley equivalent , it required changes to the hub as well as to the wheel itself .
the statement above reveals the difficulties faced by the major cycle manufacturers because of the cheap and poorly - made bicycles that threatened to ruin the cycle market . the immediate solution for companies such as rudge - whitworth , humber , raleigh , etc was to reduce prices and provide a guarantee . but some manufacturers went further : instead of using components that were freely available and interchangeable , they made every part of their bicycles themselves so that the parts were unique .
but the 1930s weren ' t kind to rudge . profits had been largely spent on its motorcycle racing exploits , so when the great slump struck , there was nothing in the kitty to tide the company over . the receiver had to be called in and rudge was sold off piecemeal . when john pugh died , broken - hearted , in 1936 , only the motorcycle business remained .
bearing which was patented in 1878 ( british patent no 526 ) this invention , when fitted to the rudge cycles , considerably the improved their efficiency and provided the long term success of his company .
although pneumatic tyres were introduced by 1890 , in the first few years they were an expensive option , so they were available more in principle than practise . most bikes had solid tyres . the freewheel was not introduced until 1898 , so 1896 bicycles were still fixed wheel . but 1896 rudge - whitworths had detachable chainwheels ( patented by raleigh in 1889 ) allowing for inter - changeability . the 1896 rudge - whitworth catalogue also introduced ‘a new principle in bottom bracket design , being adjustable , dust - proof and oil - containing’ and a ‘ball head adjustment of novel design . ’ seat tubes were wider ( the same as modern bicycles ) and pedals no longer had slotted cranks .
emi , of all people , eventually bought that with the intention of moving operations to its hayes factory in middlesex , but war with germany once again intervened . jaguar acquired the rights to rudge ' s wheel business and together with dunlop continued to exploit the design — first with wire wheels , then disc wheels — long after wwii finished , on the xics , c - type , d - type and e - type . similar designs were used by others like mg . simple , effective , failsafe , the rudge - whitworth wheel was an object lesson in how a little original thought can save a lot of engineering complication . so why isn ' t it still used ?

the team prize was also resurrected in 2015 as another little nod to history , and lies in the origin of the noel hammond memorial trophy . in its very first incarnation in the 1930s it was known as the rudge whitworth 50 , and was awarded in the 30s and 40s for the winners of a team 50 mile time trial ( not the same as a 50 mile team time trial ! ) , where teams of 6 were invited to compete and the best 4 times counted .

founded in 1894 through the merger of two bicycle makers , rudge - whitworth moved into motorcycle production in 1911 . they made a name for themselves with some technological innovations ( such as the multi gear system which allowed for 21 speeds ) and some racing success . after starting with a 499cc single , their new model in 1924 was called the four . but the name did not come from the number of cylinders , like you’d expect . in fact , the new engine was a smaller single of just 350cc . “four” instead came from the fact that the bike had four speeds and four valves . don’t fret – the newer 350cc put out much more power than the old 500cc .
in 1912 the belt drive 499 cc rudge multigear was released , using variable groove - depth pulleys to gain 21 forward gear ratios , and a top gear as high as 2 . 75 : 1 . ( the zenith gradua and 1907 fn 244 cc single used a similar system . )
the early strutted rudges did not enjoy much success . however , as the dirt track surfaces became slicker the rudge came into its own and by the end of 1930 it ruled the roost . its success was short lived it would be ousted , in turn , by the speedway jap . [
the production at coventry of aero - engines and aircraft by motor - car firms has been described above particularly with reference to the two world wars . ( fn . 617 ) both these industries have been dominated in the city during peacetime by the activities of those firms which since 1948 have formed the hawker siddeley group . despite the production of aircraft by humber as early as 1910 and the activities of various car firms in the first world war the aircraft industry did not become really important in coventry until the early 1920s when armstrong whitworth ' s aircraft and motor sections were transferred to coventry . ( fn . 618 ) armstrong - siddeley motors then developed the production of aeroengines , ( fn . 619 ) while the sir w . g . armstrong whitworth aircraft company , formed in 1920 and also controlled by the armstrong siddeley development company , began to produce aircraft . in 1923 the aircraft company moved from london road to whitley where production of fighter aircraft commenced . in 1926 the firm entered the civil aircraft field and as early as 1930 was employing some 1 , 200 men . ( fn . 620 ) in 1935 the armstrong siddeley development company amalgamated with hawker aircraft to form the hawker siddeley aircraft company which became the hawker siddeley group in 1948 . ( fn . 621 ) in 1961 armstrong whitworth was merged with gloster aircraft becoming whitworth gloster aircraft . ( fn . 622 ) alvis entered the aero - engine trade in 1935 when the firm built a newfactory for this purpose next to its motorcar works . ( fn . 623 ) in 1963 this side of alvis ' s activities accounted for a substantial part of its turnover . ( fn . 624 )
italian carlo borrani licensed the rudgewhitworth design for his famous wire wheels , which ferrari used on its grand prix cars into the early 1960s . rudge ' s wheels were also used by german giants auto union and mercedes during the 1930s , proving themselves well able to transmit engine power in excess of 500bhp and sustain speeds of over 250mph in the rekondwoche runs . all with just a couple of firm , not heavy , blows of a copper - faced hammer to tighten the eared spinners — a refinement of the original rudge design introduced by peugeot in 1913 , in place of a large spanner .
rudge bikes finished first , second and third at the 1930 junior tt using prototype radial 350cc 4 valve engines . they also took first and second in the senior tt . the road bike engines were changed to dry sump lubrication . the jap 250 and the parallel four valve 350cc ended production in this year .
the first world war stimulated the cycle industry . rudge - whitworth , for example , delivered thousands of cycles and motor cycles to the army . ( fn . 256 ) in the early 1920s , however , there was another slump , ( fn . 257 ) the competition of motor cycles and cars helping to cause a decline in the popularity of bicycles . ( fn . 258 ) from 1926 mass - production methods reduced the number of cycle manufacturers . like rover , singer , which had acquired the coventry premier cycle company ( formerly new premier ) , ( fn . 259 ) swift , triumph , and riley all gave up the cycle side of their businesses in the face of competition from the mass - production firms .

daniel rudge was born in january 1841 . after serving with the 38th regiment of foot he returned to wolverhampton and opened a public house called the tiger inn in church street near to st john’s church . at the same time an army colleague henry clarke started a wheel building business called the temple street wheel works .
