We love LEGO and we also love Crazy Circuits so we wanted to combine the two into a simple and fun robot that can avoid running into walls and other objects.

We’ll show you how we built ours, and outline the basics needed so you can build your own. Your version might not match ours exactly, and that’s okay.

Below is a list of the Electronic Parts we used, and a list of the LEGO Parts we used. Your parts may vary, so don’t be afraid to do your own thing.
