This is a MicroBit robot based on Kitronik Motor Driver Board V2. The aim was to make a robot that could be used by different students per lesson and at a low cost. The whole robot (without MicroBit) should cost around £20 or less if bought in bulk. The motors and wheels are cheap to buy as well as being acurate and robust. The build once printed took only a few minutes and can be compleated by students, without tools (screwdriver needed for motor points). The code added is for obstacle avoiding robot, using Sonar:bit and the Kitronik motor board. The Sonar:bit is expensive (£7) but it is low voltage and uses only three pins.
