removed rear caster and inverted the chassis, this let me use the base to mount a 3000ma 7.2v racing pack to provide power for the servos. electronics are unchanged it is still using a Basic Stamp 2, It now uses 2 Daventech SRF-04 ultrasonic sensor, for collision avoidence, although im still trying to get them both to work together, i think the problem is my controller board is not suppling enough current to power both SRF-04's at the same time.
