Hi, Recently, I have connected the wires out from the 4 motors ports on the HB and then directly connected to the driver L298.Next, the o/p of L298 is connected to the stepper motor which drawn 3A. I supply 4A parallel to the 2 motors. Hence, each (...) (26 years ago, 20-Sep-98, to lugnet.robotics.handyboard)

Ok. If you used 2 motors in m1(right) & m3(left) , and your sensor was at the front (and only one), and in port 15, a short program for running it could be: /*Start of avoid.c */ void main(){ while(1){ /*Puts program in an infinite loop*/ fd(1); (...)

Can it be done? I'm using the Handyboard to control my hexapod robot and weight is a problem. At the moment I have 8 AA batteries connected which are not particularly weight light. I'm not using any of the motor driving functions of the board, just (...) (26 years ago, 14-Sep-98, to lugnet.robotics.handyboard)

(...) There's many ways you can approach obstacle avoiding. There are neural nets, evolutionary code (incl. genetic programming and genetic algorithms), finite state machines, and there's hard-coding it into the program (which, of course is no fun (...)
