The second annual Pi Wars competition occurred in Cambridge this past December, and just like the year before it was a complete success. If you haven’t heard of Pi Wars, then get used to seeing the name because this event will only keep getting bigger. Pi Wars is a robot competition that centers around each robot having a Raspberry Pi at its core. There are a series of challenges in which entries must compete, and at the end of the day winners are declared. Some of these challenges are the infamous obstacle course and Pi Noon (a robot vs robot competition). Entries are also judged by factors like code and building quality as well.
