Pi Wars 2020

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. The competition is open to anyone from around the world and often features teams from countries including all countries in the UK, the USA, China, Malaysia, Hong Kong and Nigeria.

When and where will Pi Wars take place in 2020?

Pi Wars 2020 will provisionally (see below for details of the team needing more help this year!) take place on 28th & 29th March at the Cambridge Computer Laboratory (William Gates Building) in Cambridge, UK.

This is the same venue that we have used for the past four events. The address is: Cambridge Computer Laboratory, 15 JJ Thomson Ave, Cambridge CB3 0FD

School teams will compete on Saturday, 28th March and all other teams will compete on Sunday, 29th March.

After consultation with past competitors, the dates were chosen because:

  1. It avoids most schools’ exam period.
  2. It avoids the Easter school holidays.
  3. It is the closest weekend we could manage to the ideal ‘beginning of April’ date most people requested.

We need help to make the event happen!

As announced on the Sunday of Pi Wars 2019, and following some post-event discussions, Tim and Mike very much want Pi Wars 2020 to take place. However, due to the size of the event, and the work involved, it needs to work differently from past years. The initial feeling, that we might do a big event every other year with regional competitions in the “gaps” felt, to us, like watering down the concept too much. We’re still open to other robotic events in the Pi Wars mould, possibly even using the name, but to keep the consistency and quality of the big event in Cambridge, we’ve reconsidered our plans.

For the 2020 competition, due to other priorities and responsibilities, Tim and Mike will need significant help from the Pi Wars, Raspberry Pi & Maker communities to make it happen.

Can I enter a team to compete?

Applications for the 2020 event will likely open at the end of June 2019. If you have any questions before then, please contact us.

How can I get spectator tickets?

Tickets for spectators will be available in December 2019.


We are open to suggestions for themes for the 2020 competition. Please contact us if you have any ideas!

General Rules

General rules will be released soon!


Challenges will be announced once we’ve made progress on planning.

Discuss and Chat

This year, we are running both Discussion Forums and also a Chat server on Discord (Tom Oinn‘s idea!). You’ll find some competitors on the Forums, some on Discord and some on both!

Hints for Robot Teams

Brian Corteil of Coretec Robotics, and double-winner of previous Pi Wars competitions, has written this excellent list of hints and tips for robot-building teams.
