Robot Buggy Part 2 The Line Following Buggy

The line following buggy for the BBC micro:bit is a great kit for students to build as it combines several elements of design and technology; electronics, mechanical assembly and coding. The kit has relatively few parts and is simple to build, making it a suitable option as a classroom activity.

We had initially decided to create a new and elaborate chassis upon which to build our creation but decided it would be easier for all concerned if the buggy could be built and tested as is and the modifications to be an as well as rather than an instead of. As well as making this activity more accessible, it also means that the buggies can be returned back to their natural state by simply removing a few screws and lifting the top off.
