Turns out that rechargeable batteries and the L293D motor controller really slowed things down. Added another battery pack, and with 12 volts the bot actually moves. No smoke coming out of the motors, so all is well….
Batteries almost ran out by the time the bot finally made it trough the obstacle course…Still WIP I guess.
..or rather what is left from a perfectly decent remote controlled tank! http://www.youtube.com/watch?feature=player_embedded&v=ff5dCPZQmjs
