A 120:1 plastic gearmotor with a 90° output shaft — the output is perpendicular to the motor axis, making it a compact choice for small robot designs where side-mounted wheels or mechanisms are needed. The enclosed gearbox and low-current brushed DC motor run on 3–12V, with a built-in safety clutch that slips before gear teeth can shear.

At 6V, the motor delivers approximately 75 oz·in of torque at 85 RPM, with a low 70mA free-running current that makes it a good match for small motor drivers and robot controllers.
