Pi Wars – the Raspberry Pi robotics challenge competition

What is Pi Wars?

Pi Wars is an international, challenge-based robotics competition in which teams build Raspberry Pi-controlled robots and then compete in various non-destructive challenges to earn points. The competition takes place over a single weekend and prizes and medals are awarded to those competing at the end of each day. In previous years, we've had teams from schools, families, groups of hobbyists and solo roboteers. We can take up to 76 teams over the event weekend which takes place in Cambridge, UK. The competition is open to anyone from around the world. To get a flavour of the day, take a look at the video below or check out other Pi Wars videos on YouTube.
