How fast can your robot run in a straight line? How close does it follow a wiggly line? Can it escape from a maze? Can it sink the putts in 'slightly deranged golf'?
These are all among the challenges competitors face. Points are also awarded for artistic and technical merit, as well as a special award for the 'funniest robot' - a nod to the fact that this year's event takes place on April 1-2 at the Cambridge Computer Laboratory.
As a sponsor, supporter and exhibitor at Pi Wars, we've been keeping track of how preparations are going:

Life is always easier when you've got the right tools for the job. Last year's #PiWars motors compared to this year's. 🚀 pic.twitter.com/z5irx6l3tL— David Pride (@davejavupride) January 18, 2017
