As well as creating accessories for the micro:bit, we support ChickBot.club with our services. They have developed a low cost (~£10 in bulk) robot platform. The micro:bit is fully supported by the ChickBot system.
For details on what you are buying, see the ChickBot micro:bit kit page. In summary, you get a complete pre-prepared kit to make a robot apart from a micro:bit and 4 AA batteries. No soldering required, you will need a pair of scissors and about 30 minutes to assemble.
We are in the process of documenting and uploading all the activities we have developed over summer 2016.
The ChickBot micro:bit robot won the micro:bit line follower & drag race category at the recent IET Robot Triathlon in Derby.
