Bonasso describes a three-layer, subsumption-like architecture he calls
``layered competences'' (\cite{bonasso90} \cite{bonasso91a}
\cite{bonasso91b}).  He allows more communication between layers than the
subsumption architecture and the circuits operate synchronously (due to the
use of REX/GAPPS \cite{kaelbling87}).  Perception at every level is task-directed.

They developed a pilot's assistant for an underwater remotely piloted vehicle
which takes heading commands from a joystick and moves the vehicle in the
indicated direction, avoiding obstacles and holding its 3-D position once on
station.  The architecture was also demonstrated on land vehicles (a Hero and
a Denning, \cite{bonasso91b}).  The original description of the architecture
was in \cite{bonasso90}.

Most activity is in tertiary institutions or the CSIRO.

The following are presented in no particular order, except my group is
first.

Mobile robots:
Intelligent Robotics Research Centre
Monash University, Clayton Campus, Melbourne.
Prof. R. A. Jarvis

Comp. Sci. Dept.,
University of Wollongong,

Industrial (robot arms etc.)

UWA
James Trevellian's group (or speak to Peter Kovesi in Comp.Sci).

Robotics and Digital Technology
Monash University, Caulfield Campus, Melbourne

CSIRO department of manufacturing technology,
Preston, Melbourne.


There are, ofcourse, others but these are probably the best known.

If you get in touch with Dr. Trevellian or Dr. Kovesi, they will be able to 
point you in the right direction.

Hello There

I just finished assembling my miniboard and switched it on. I noticed all the green
(I think) LEDs for the motor were on full brightness. The red LED for the serial line
was on and the green LED for the serial line was off. I do NOT have the
microcontroller in its socket.

Is the board OK? I'd really appreciate if someone could tell me how to make sure its
working.

There must have been a misunderstanding between you and the LEGO
representative.  The package you mention (LEGO Dacta #9853) retailing
for $16.00 consists of the following:

    * eight (8) 40-tooth gears
    * fourteen (14) 24-tooth gears
    * eight (8) 24-tooth "crown" gears
    * thirty (30) bevel gears
    * ten (10) 16-tooth gears
    * fifty (50) 8-tooth gears
    * two (2) differential joint housing

This is quite a nice assortment!  Certainly enough for a few
geartrains.

No.  We order the 6.270 parts kits partially from the USA LEGO Dacta
catalog, and partially from a special affiliation with the LEGO
Denmark headquarters.

For everyone's info:  the USA number for LEGO Dacta (the educational
division of LEGO that sells LEGO Technic direct) is (800) 527-8339.
I'm sorry but I don't have a normal phone number for international

     It's worth noting that there are other suppliers of M68HC11 boards.
The price is higher, but you get delivery.

     New Micros, 1601 Chalk Hill Road, Dallas, TX 75212,
(214) 339-2204 sells small M68HC11 boards, down to 2" x 2" size.
These come with Forth on-chip, although you don't have to use it.
I've used their boards with good results.  They've been shipping
boards since 1986 or so.

     Embedded Systems Journal, Circuit Cellar INK, and Nuts and Volts
all carry ads for board-level systems.  Prices for 68HC11 boards seem
to run in the $100-$300 range.  8051-based boards run cheaper, as low
as $38, and quite powerful systems with small form factors are available
for a few hundred dollars.  I don't have any experience with any of these
companies other than CuBIT, from which I bought a nice NEC V40 board a
few years back.

     It's tough selling electronics for less than 4x the parts cost.

                There is no specific source code for the power glove.  
There are several codes that do allow the user to access different 
features of the power glove, however one good thing to do would be to 
connect the outputs of the pg to an oscilascope.  You'll find that 
different bottons produce different control pulse widths.  You can then 
read the different time sequences coming out of the pg... thus you'll be 
able to have the computer do different tasks depending on what your 
program causes it to do.  It's quite a simple concept.

Subject: Macintosh/Unix versions of Motorola's AS11 6811 assembler
Date: 22 Dec 92 05:23:59 GMT
Organization: MIT Media Laboratory

Greetings Macintosh and Unix-based 6811 programmers,

I've installed ports of the Motorola "as11" 6811 assembler program
onto the MIT Media Lab server machine.  This code is Motorola
freeware---yay, no sending money or waiting for disks!

The Mac port is in pub/miniboard/mac/as11.sit.hqx.  There is a
double-clickable application and Think C 4.0 source code.  A Mac
downloader for the resulting .s19 records is named dlm.sit.hqx in that
directory.

The Unix port is in pub/miniboard/unix/as11.tar.Z.  There is no
executable but it should compile easily; I've cleaned up a few
problems with the original PC-oriented sources.  There is a version of
the downloader program with changes to work with Unix serial lines
that were made by Ted Dunning.


So, 6811 assembly hackers can program away with freeware based systems
now.  I hope to port the Mini Board C libraries for use as assembly
language subroutine libraries; this would make programming in assembly
almost fun!  

Now, if the freeware 6811 Small-C system weren't so durned MS-DOS
specific...has anyone ever had any luck porting that thing?


Holiday cheers,

Fred

Date: Tue, 22 Dec 1992 17:16:31 GMT

Hi,

Hate me if you like, but I posted erroneous data about infrared
remotes, and I thought it would be better to repost, so I fixed
the figures and added info about the continuous key mode.

I found the postings about the Sony infrared remote control
protocol interesting, but I was alarmed to note that it did
not seem to mesh with the readings I got from 3 different
controls in use in my living room. These are an RCA t.v.,
an Onkyo receiver, and a Jerrold tuner.

Here is what I found (presence of signal = logic 1):

First, there is an AGC stabilization pulse, followed by a short
break. Then come the mysterious bit patterns (I'll get to them).

Signal			Duration	Polarity
------			--------	________

AGC pulse		9.15 ms		1
pause			4.33 ms		0
50 3-bit patterns	1125 us		(see below)

Each 3-bit pattern consists of three 375 us. long bits.
The first two are always the same, and convey the binary
information. The last is always set to 0.

When these bits are laid out end to end, they look like
the following (actual data from one of my controllers):

11 01 11 01 10 10 10 11
01 01 10 10 11 10 10 10
10 11 11 01 11 11 01 01
01

There are two interesting features of this stream, neither
of which I am sure is always true, or merely an artifact
of the particular button I chose.

1) The pattern 00 never appears
2) The pattern 10 never precedes the pattern 01

Note that this can't be what I believe is called Manchester or
simple phase encoding, because of the presence of four con-
secutive ones. My grouping of bits into pairs is only based
on a gut feeling, and may be a red herring.

When some keys are held down continously, a different type of
packet is sent. It looks like this:


Signal			Duration	Polarity
------			--------	________

AGC pulse		9.15 ms		1
pause			2.10 ms		0
stop pulse		750 us		1

time until
next packet		38.6 ms		0


As I have said before,
if anybody out there has more information to add to this,
I would be eternally grateful.

In other fields, technical reports are considered "inaccessible",
hence not fair game for citation.  This is a case in point, where the
author is having a hard time tracking the thing down.  If the idea is
really worth citing, then it should have been published in a more
accessible form.  At the very least, the reviewer should have
suggested a more solid reference.

There is not now and never was a "68hc11e2fn".  If you look closely,
the Mini Board parts list calls for the 68hc118e2fn; somehow the
Motorola sales rep must have figured out this is what you really
wanted.

By the way, a key to decoding Motorola part numbers might be of
interest.

For pulleys and bearings, contact Kaman Bearing at Frank Rd Industrial Park,
2200 Hardy Parkway Box 23107, Columbus OH 43223, phone 614-871-1893.  They
distribute stuff from SealMaster, SKF, Link-Belt/PTC, etc.  Excellent,
excellent high-end stuff.  Bought some pillow blocks from them about two
years ago -- spent $120 for four SKF (?) pillow blocks, still working great
under high load.
Do make sure you check out their instructions before ordering; you want to
get what you really need.
Kaman Bearing can probably give you someplace to get other types of pulleys
and possibly gears.  Dunno about motors tho.
