This small yet powerful motor is great solution for small robot, example balancing robot :)

We have been carrying SPG10 motor for quite sometime and it has serve the makers community well. It is being used in Edubot2, Aluminium Robot Chasis and the famous DIY PR23-B multifunction robot. With the standard size and varirty of gear, user can always change the motor on existing design. Many are using it to build small mobile robot for sumo, small automation model and of course other application too. This version of brushed motor comes with 150:1 gearbox attached. The gearbox output shaft is a D-shaped with 9mm long and 3mm in diameter. There are several types of wheel that you may use together with this motor.

All SPG10 motors are DC brushed motor with gearbox. The rated voltage is 6V, yet we have tried to drive this motor from 3V to 9V. Lower voltage might not have enough torque to drive the wheel or mechanism; higher voltage will provide higher torque and higher speed, but it will shorten the life of the motor.

For Arduino lover, get the 2A Motor Driver shield to control this motor with Arduino.
