This sturdy robot for the BBC micro:bit (included), boasts a sheet metal body and a recharge circuit for Li-ion batteries, as well as multi-coloured LEDs, stable line-following sensors, and a distance sensor mounted on a pan/tilt bracket. Oh, and did we mention it runs on tracks for navigating more interesting terrain?

Documentation and code examples are available here.

Note: this product requires one 18650 battery to work, which are NOT included and should be purchased separately.

 FEATURES
