The Micro:bit STEM robot car is an easy to program 2 wheel obstacle avoidance and line tracking robot. Coding your program is easy using the standard BBC Micro:bit software. It's the perfect introduction to robotics for children which can be self coded with instruction from teachers. It has been designed with a BBC micro:bit slot on board, this means a classroom may only need a few STEM robot cars to cater for multiple BBC boards. Each child can program and code their micro:bit, plug it in and then try it out in the robot car to see if it works. Wiring and construction has been designed to be as simple as possible. To control simply use any standard open source Bluetooth control app on a smartphone or tablet.

It integrates ultrasonic and infra-red obstacle avoidance, line following, plus self control via Bluetooth. It is fitted with a passive buzzer for playing music tones, a module for controlling 18 RGB LED colours and a photo cell for detecting light intensity. It's also fitted with two RGB LEDs as directional movement indicators.

Easy to follow instruction booklet provided. Runs from 18650 rechargeable lithium cells (sold separately).

NOTE: Picture for illustration purposes, BBC micro:bit sold separately.
