These Solarbotics GM2 - Gear Motors are very comparable to a hobby servo for power, at a fraction of the cost! Fit perfectly with GMPW and GMW plastic wheels.
This gear motor rotate 360 degrees every 1.6 seconds (just a hair slower than a servo), at 5V, drawing 600mA at stall (free running at 52mA). With a 7mm double-flat output shaft (avoid using the "D" output - it's not meant to take rotational load), With a 7mm double flat shaft and a built-in clutch (limiting at 60 in.oz, but easily "locked"), and built-in mounting screw holes, you can see why we like these motors! These units have an overall size of thick, while only weighing.
Based on the original design by Mark Tilden for use in the B.I.O.-Bugs (GM3 are now used for use in the Robosapien), these motors are the next generation with a variety of improvements such as dual output shafts and a lower current motor.
GM2 - Gear Motors are compatible with the Solarbotics Wheel Watcher Rotation Encoder. Use it if you need to control a robot for dead reckoning, tracking odometry (distance traveled), stalled motor, or closing the feedback loop for position/velocity/acceleration.
I am impressed with the apparent quality of the parts I ordered. The ordering and shipping process was painless. I paid a little more to order from RobotShop (shipping)...worth it because they had what I needed and I have confidence that the parts will work together.
