The CUB is the crumble-based buggy with a range of engaging options. Use it for drawing, line following, obstacle sensing, or all 3 at once.  It has sparkle taillight, takes broad and narrower board markers and it’s all clip together so no tools required.

If you’re looking for something different then just use the motor clip, combine it with wide lolly sticks and get creative with your buggy – from carnival float to emergency vehicle – it can be whatever you want!

Used as a drawing buggy it’s a starter activity to buggy control. Challenges to draw geometrical shapes, outlines of almost anything or get mathematical. You can work out the mathematical link between what’s on the program and what the buggy is doing. It all in the CUB Cookbook – available now!

If you already own the kit, you have the option to buy the chassis on its own.

  • Robot chassis with pen holder for narrow and broad markers
