Perhaps the problem is your motor-drivers IC's. If you use the L293D or
something, which are standard on the HandyBoard, you can only draw abou
600 mA. I use the other ones mentioned in the HB manual (they're from
Texas Intr., but I can't remember the number right now), which allow you
to draw up to 1A. If you drivers IC get hot, this could be the problem.
If you only use 2 motors, you could also try to use different driver IC
for both (e.g. use only 'motor 0/1' and 'motor 2/3').
I saw a program on robotics a while ago on Discovery, and there was a guy
who builded a complete zoo of robots consisting of only a couple of
transistors. They did move indeed, but he said they were adapting to their
environment, which I find hard to believe.

| Hello everyone. I finally got everything cool with the Handyboard I'm using in terms of the software and loading it and getting all connections right. The only problem now is that the motors on my little robot pretty much stop after maybe 45 seconds (...) (27 years ago, 17-Mar-98, to lugnet.robotics.handyboard)
