This 60:1 gearmotor (gearbox with motor) is a low-cost way to drive small- to medium-sized robots. It is similar to the Solarbotics offset-output gear motors, but it draws more current and has a much higher RPM.

This 60:1 gearmotor (gearbox with motor) is a great low-cost alternative to modified hobby servos or Tamiya gearboxes, and a higher-speed alternative to Solarbotics gearboxes. This gearmotor comes pre-assemebled, with the gears fully enclosed. There are built-in mounting holes that are compatible with the Solarbotics mounting bracket (1451-101), and the output shaft is 5.3 mm in diameter with two sides flattened to a thickness of 3.6 mm. Note that this is smaller than output shafts on the the offset-output Solarbotics gear motors, so Solarbotics wheels are not compatible with these gearmotors. See 'Which Wheel' tab for suitable wheels type SR for a tight fit.
