The primary feature of this high-efficiency gear box is a worm gear, which locks the output shaft whenever the motor is not turning.
The high gear ratios of 216:1 or 336:1 make this gearbox appropriate for small walking robots, lifting mechanisms, and other applications where high torque is desired.
The low-voltage motors run on 3-6 volts and draw up to a few amps, making them perfect candidates for the Pololu Orangutan LV-168 robot controller Product Code 775, which incorporates these low-voltage motor drivers.
