A hybrid bipolar stepping motor. It has a 1.8° step angle (200 steps/revolution). Each phase draws 500 mA at 10 V, allowing for a holding torque of 1 kg-cm (14 oz-in).


Zippy Flightmax. Provides power to the motor drivers, stepper motors, sensors and microcontroller.Capacity: 1300mAh Voltage: 3S1P / 3 Cell / 11.1v Discharge: 20C Constant / 25-30C Dimensions: 76x33x21mm

Motor Driver

DRV8825 is a microstepping bipolar stepper motor driver. It features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step).


STM Nucleo-401RE. It is the brains of our Micromouse which provides onboard data processing and control of peripheral systems.


Sharp IR GP2Y0A51SK0F. It can sense between 2-15 cm. It's output DC voltage is 1-3V


Custom built metal. 70 x 8 mm.
