I think your trouble come from the H-bridge chip (L293D), it doesn't
support more than 600mA of current draw, and reset or crash the board then
this value isn't respected.
To solve this trouble, I used instead the L298N, it support up to 1A. In
fact, I used two L298N, one other the over, soldered together, this way it
support twice more. You can do this with the L293D too.
Notice that this way is a bit hazardeous, particulary if you're not good
at soldering.

| Hi All, I Just created a (my first) mobile bot with two motors using differential drive. At random moments, during motor activity, one of the motors (or both) seems to go wild and soon after that the BATT led blinks and then the board is reset. I (...)
