Did you find what you needed?

Stepper motors CAN be smooth! And stepper controllers can be strong and cheap. Roman Black's Linistep stepper controller kits:

o 18th microstep
o Linear smoothing

o Open source
o Full kit $25!

Robotics nuts!

Check out http://users.frii.com/dlc/robotics/projects/botproj.htm from Dennis Clark. This guy ROCKS! He has made (and sells but also releases code, docs, etc...) for a number of cool little robotic modules including whiskers, IR proximity detect and remote control, Sonar proximity detect, PWM, Servo, compass. Most of these use the little PIC 12C508 controller which costs basically nothing and is soooo tiny.
The 4 servos, 2400 baud serial servo controller is a wonder of magic and he sells the programmed chip for $8. Wow!
