Solarbotics is the sole commercial outlet for these impressive 224:1 gearmotors, which are very comparable to hobby servos for power, at a fraction of the cost!
This model differs from the GM2 in that it has a 90 degree output shaft.
Based on the original design by Mark Tilden for use in the B.I.O.Bugs & RoboSapien, these motors are the next generation with a variety of improvements such as dual output shafts and a lower current motor.
Do you need to mount something to the shaft of the motor? Try the GMW - it's a very effective platform for a variety uses. Alternatively, you'll also find that a #2x1/4" SMS screw will provide a snug fit for your need.
Motors are sold individually, wheels are not included.
