Sumo won''t turn and moves slowly

The SumoBot uses servos for locomotion so it doesn't use the kind of PWM signal
intended for DC motors.

Hello Gregg,
Looks like this topic is very new to me. My question
is related to the SumoBot. I'm new with the robot as
well. Can someone assist me on my problem? Besides
that, I'll also look up for PWM.
Thanx.
