If you were referring to me forgetting about matching impedance, thanks, I

11533 Tuesday, March 07, 2000 12:14 PM ideas beam@sgiblab.sgi.com jeremy i have a few ideas for other peoples ideas

one the having the idea for a robot is a good idea, but right now solar
panels is just easier right now. a few things that will need to be changed
are 1 identifing the food (you dont want it eating your other bots), having
the bot to know when its full, developing a stomach.

the first step is to identifing the food which will be hard to do, as for
making a stomach i sugest using batteries as a step.

two having the bots talk to each other is a goal that can be acomplished.
my idea would have the be completely silent, but when the bot found food the
extra energy would power the speaker to make a beep thus giving the location
of the energy to the other bots. this idea would require that the bot be
able to eat, and the food source be obstucted from view. the goal would be
for the bots to tell that the found food and where it is. probably easir
than getting the bot to dance to tell where the food is. a side effect of
eating is the waste it creates better teach it to use a litter box

three if you gave the bot memory it migh be able to learn to an point. if
you gave the bot memory for about 30 minutes then let it walk then turn off
the lights for about 10 seconds then turned it on again, then let it walk
for a while. repeat this step several times then put books on the top of
your RJP to create shadows. the bot may be afraid (not in the same sense as
humans, but close) of the shadows. this would mean it knows the effects of
darkness and it would avoid it. this idea would require a small battery
that would activate while its in darkness so it doesn't forget the lesson,
but a battery small enough that it wouldn't power the motors but enough to
power the circuts. it would record sensor output but when the lights go out
it would record no lights and no motor output with any luck it would put
those two things together. its main ppower source would be solarpanels

Well i have finallly finished one of my solar devices, it was based on the
photopopper
circut and works prety well, had a few teething problems with the larger
motors i was
using but soon got them sorted out :)

Next up is something that is going to be a little more challangeing, and a
lot larger
i was contemplating a walker or high torque wheeled unit opperating from a
bicore
circut.

But before starting i thought i would ask a few questions.

When designing a 2 motor walker, how do you tell the bicore where the leg
is?
is this self governing or is there need for stops and sensors for this?

If i choose to build a wheeled unit whould that not mean that only one motor
would be opperating at any one time?

or on wheeled units do you setup independent bicores to controll each motor?

Regards
Andrew
