Perhaps your motors draw too much current. You can only draw 600mA from
the L293D driver IC. In the HB manual, you can see you can draw 1A from a
IC from TI. (I don't know the exact number right now).
You could try to use a seperate IC for each motor, if you only have two
motors running at once (eg. only use motor 0/1 and motor 2/3
simultaniously.) If your L293D's get really hot, this might be a solution.
I saw an other program Discovery some time ago, in which a guy had build a
zoo of robots, all build from old Walkmans and only containing a couple of
transistors. They did walk, and the guy who build them, said they adepted
to their environment, but I found that 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)
