Main Modules Introduction

Ultrasonic connection and micro:bit IIC port are placed in the front part of the Cutebot.

Two full color RGB lights controlled by the expansion board are placed on both side of the front part.

An expansion board for 3x AA batteries is placed in the right above part of the Cutebot.

The IIC port and Servo Port(S1, S2), P1,P2 IO connections are equipped in the battery expansion board.

The infrared probes connecting to P16 port of the micro:bit are placed on the tail part of the Cutebot.

The master switch are placed besides the infrared probes and with on/off status showing by the LED.

The two wheels on both side are driven by DC micro gear deceleration motors(300 RPM).
