Subject: [alt-beam] You wanted Walker leg info?
...here it is. I took 10 minutes and generated this PDF of just the leg
layout pages. It's not listed on the website, so here's the link:

wow ...thanks dave..actually i do have the manual sent by paul argo to me
for free(he is nice) i just dont understand the content of that page but it
would be better if u could explain better in detail to me...i am not so good
in english actually....by the way what material did mark uses for his
walker....it seemed so hard to bend..and why did he use it...and why is
there several bicores in the two motor walker....i thought just two or three
is more than enough...thanks a million dave

ermm dave the pdf file is exactly the one pau lsent me....ermm okay i read
it three timesbut i got these conslusion ..i hope u could correct me if i am
wrong....
okay here goes......the walkers leg must be in a square which the distance
between the FR ,FL , RR, RL leg must be the same...but why in mark T
solarwalker...the two front feet are smalll than the rear ones..i mean the
width.....hope i could get an explaination.....and why does he need so many
bicores board in one two motor walker

brain cells per each muscle we have. It may be a form of biasing to turn
the robot. You CAN turn a 2 motor walker, but it's very sensitive, and
it helps to be well balanced in the center. I myself would love to know.
It's also possible that he wired some of the 240s as motor drivers too.

6359 Mon, 04 Oct 1999 11:17:21 -0400 [alt-beam] Solderless techniques Those Brainy Beam People Peter Low Has anyone had success (or tried) in building 'bots without
soldering? What are the alternatives (wire wrapping, breadboard,
others)? I don't have a dedicated work space, and it's kind of a pain for
me to set up for soldering. These techniques may also help beginners
(debug the circuit instead of debugging the results of mistakes made while
soldering). Any suggestions would be appreciated.

6360 Mon, 04 Oct 1999 11:29:46 -0400 [alt-beam] Re: Mark T first bot beam@sgiblab.sgi.com Ed Spike I believe his three legged walker was really a jumper. It looked like
R2D2 on stilts. This he had in 1990 for the demonstrations at the
Ontario Science Museum for the IEEE MicroMouse Contest sponsored by the
University of Waterloo IEEE Student Branch and co-chaired by Mr. David
Stampe and myself. Mark Tilden and I later co-chair the IEEE/BEAM
Robotic Olymipics and MicroMouse Competitions. I will try to dig up
some pictures.

6361 Mon, 04 Oct 1999 10:39:02 -0500 [alt-beam] PBS Beam specials - how to find them? beam@sgiblab.sgi.com "Paul Atkinson" Can anyone tell me which PBS these shows are on? I know PBS is public
broadcasting system, but there is a satellite version and each 'local
market' has it's own station. I can not find either of these shows in
the satellite listings or the listing for the broadcast station in my
local area. Any clarifications? Anyone?
I would really like to see one or both of these shows!
Thanks, Paul

Front ones could be narrower because the motor he's using doesn't have as
much torque, and can't lift the body if the legs are that long. The
distances don't have to be the same, but the balance does matter quite a bit.

Lets's see. 2 for bicores, one for reverse muxing, one for eyes/sensor
mounting, one for battery/PM2 module connections, and one just to even out
the symmetry. Easy to hit 6!

hi has anyone dealt with the TIP-32b PNP transistor before? does anyone
know of the pin layout? its in a i believe, TIP casing.. able to attach
heatsinks. pls help.. thanks
