The Cub derives its name from from the acronym for Crumble Universal Buggy, and it certainly lives up to it!
The 3D printed chassis from UKSTEM caters for line-following, obstacle avoidance and line drawing. The kit includes both a line-follower module and an ultrasonic distance sensor, and the pen holder takes broad and narrower board markers. All parts, including the Crumble and its accessories, simply clip together, so no tools are required for assembly.
Used as a drawing buggy, it’s a great introduction to controlling robots. Challenges can include drawing geometrical shapes, repeating patterns or get mathematical and work out the link between the program and what the buggy is doing. We highly recommend using the buggy with a white board marker on a surface that can be cleaned to allow for experimentation.
Using the line follower or ultrasonic module allows investigating and programming autonomous vehicles.
