| 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 (...) (27 years ago, 17-Mar-98, to lugnet.robotics.handyboard)
