      There are commercial model blimps set up for R/C control.  I've
seen them, but don't have a manufacturer.  Payload is low, but sufficient
for R/C control and battery-powered propulsion.

      Some Media Lab people tried to convert some of these units to
autonomous operation, but never got it working, despite what it says
in Brand's "The Media Lab".  But there's a group in (I think) Austin
TX which had some model blimps with steerable ultrasonic sonars
operating autonmously for art performances.  I've seen a video of this,
and Joegh Bullock of Climate Theatre in SF would know who they are.

Well, I would take your approach of the "black and white" stripes on the
arrow and modify it a little bit...  If you had access to a laser scanner
assembly,  it would form an ideal high-resolution sampling device compared
to a phototransistor.  Actually, now that I think about it, a CCD element
might also do the job...  Even at top speeds of 200 ft/second, we're looking
at 38 KHz rate for 1/4" steps on the arrow with 4 points per region... Not
too bad, me thinks (for a CCD, that is)...  

The idea is to sample your image continuously at a high speed.  Then, the
only thing you need is the "start" trigger...  An edge transition in your
input...

Then, smooth the results post-collection.

Subject: Stiquito project documents - need help
Date: 20 Nov 92 17:25:53 GMT
Organization: LLUMC Radiation Research Lab

Hello there!

I've tried unsuccessfuly to print the Stiquito report after ftp'ing the three
split .ps documents, and I'd like someone's help with this problem.

I ftp'd the 'stiquito.ps.ax.Z' documents (a, b, and c), uncompressed them,
concatenated them, and obtained one PS file.  Unfortunately, I can't print it.
There seems to be some error in the postscript code, since I tried it on 2 
printers, and a screen viewer.  One of the printers is Apple LaserWriter II,
the other is a SparkPrinter, all operating on SparkStations.

I ftp'd the files twice, both times in binary mode, and both times ended up
with the same PS file, which I cannot print.  I also obtained the .W4 files, 
but we don't have any Macs at the institution, and don't have a way to transfer
it to a floppy diskette (they insist on making all devices read-only).

I wonder if you have any insights on how I can print the document, or if it is
available elsewhere in a different format.

I'd also like to know what the stiquito.hqx document is.


Thanks!

Quite right about the spool method affecting the acceleration of the
arrow.  That's part of the reason I suggested a light (low mass, low inertia)
spool of thread be used.  The error in the results would be minimal, I would
suppose.
 
I expect the spool method would be just as accurate as the original method
outlined, maybe more accurate.

The first 46 CPUs were shipped the end of September.

The second order of 138 parts keeps getting slipped.

Motorola will not deliver parts to Future until Dec 4 1992
  and the date keeps slipping so I won't be sure until they
  actually get to Future.

If Future gets the parts (About Dec 10) They will expidite
  shipping to me. I might get parts by Dec 20 and I will
  try my darndest to get them off before 11:25 Dec 22 when
  I fly to Boston for Christmas. I will return Jan 2 1993

This order has slipped three times so I wouldn't hold my breath.

Other distributors are also slipping their dates and they are now
  quoting March delivery. (Well they say Febuary but they also say
  not to count on it)

Sorry about the delays but I think that this is still your best bet 
  for parts.

We use Denning robots and are faced with a similar nightmare.  One of
the things we're working on at the moment involves using visual homing
techniques to essentially recalibrate the robot at various points in
the environment, and coupling that with motion planning.  I'd have to
agree with the other posters in that the best we can hope for (at
least in the case of the Denning) is some bound on the slippage, and
to take advantage of that bound when we can.

Hello 

We have designed a transputer based controller for a small SCARA robot
and developed some pid control routines to control robot position.
Now what we are interested in doing is, measurement of the robot
end effector position in the laboratory. If we can measure the actual
position of the end effector at say one point and command the robot
to move through a specified distance, and repeat the measurement, then
we can check the actual position accuracy of the robot.

Any suggestions for a method which can be implemented in a lab are
wellcome.

Thanks.

   I know you hate it as much as I do, but...)

   Which development tools (give brand name) you use?       

   What are your complaints about this processor and the tools available?

   Would you like more professional tools or would consider migrating to a
     more friendly processor?

   What sort of development tools (or improvements) you would like to see in

And now, the information you have all been waiting for ...

I finally got postage ang delivery information straightened out.  Here it is:

the 6811s will be delivered sometime in the first 2 weeks of January.  I was
able to bump the order up from 46 to 69, and can probably bump it up to
92 if I have enough response soon enough. (I'm not taking a chance of
being stuck with 23 6811s.)

The charge per chip will be $16.00 U.S., + insurance.
This price applies to chips shipped to the U.S. & Canada.
To England, the price will be $16.50 U.S. per chip.

These are being shipped U.S. Mail.  Insurance works as follows:
   	$0-$50.00	$0.75
	$50.01-$100	$1.60
	$100.01-200	$2.40
	$200.02-300	$3.50

I strongly recommend insuring each shipment for at least $50.  $0.75 is a
small price to pay, and it allows the package to be tracked in case it does
get lost.

Checks or Money Orders should be made out to James Malloy, and mailed
to
   Jim Malloy
   L.T.S.
   7900 Sudley Road

Please make sure to include the following
   a check for the proper amount,
   a RETURN ADDRESS inside the envelope
   a brief breakdown of the charges. (e.g.  10 chips @ $16.00 + $2.40 insurance
					=$162.40)

I will send out chips in the order shown on the following list, if I receive 
payment by 12/31/92.  After 12/31/92, chips will be shipped in the order
checks are received.

The XC versions (and this goes for all of their microcontrollers) are
"eXperimental" releases, basically beta releases of the chip that haven't
been fully tested--it's a "conditionally qualified" part.  The MC releases
are obviously fully functional.  For all intents and purposes, they are the

After getting the three files, uncompressing them and concatenating them I
printed it successfully on an HPIIIsi, Ghostview will only show the
first four pages, then it loops back to the first page.  I guess the
HPIII is a little more robust.

The *.hqx file is a Macintosh file encoded for it can be transfered across 
a network without breaking, just like uuencode for Unix.

Presumably, you don't have access to a databook, or you would have looked
there before you posted to the newsgroup.  

All the major companies publish the  data you are looking for, and you can
probably find an electronics mail order place that will sell you a book for
$10-15.

However, Motorola will probably GIVE you one if you ask for it.
As a student in Philadelphia, my local distributor was very generous with
Data books and sample chips for use in Senior Design Projects (and just
about anywhere else if you told him it was for Senior Design).  Working as
an engineer in Va, The local office is just as helpful.

My advice is to look up the number of your local Motorola distributor and
ask for the appropriate databook.  All it should cost is a phone call.
