Pi Wars 2018 – General Rules
Please read these rules thoroughly. Some rules have changed since last year.
- Robots and teams will be allocated to one of the following categories:
- Schools and other kids’ clubs.
- Beginner roboteers.
- Intermediate roboteers.
- Advanced/Professional roboteers.
- Teams will be asked at the time of application into which category they should be entered. The final decision on categorisation rests with Pi Wars in consultation with the robot team.
- Robots will compete and be ranked against other robots in the same category.
- Any competitor under 18 years of age must be accompanied by a responsible adult.
- All teams must be able to send at least one participant to the actual event.
- There is no maximum size of team, however we have found that teams of more than 10 members can be difficult to co-ordinate. We will ask how many people will be in your team later in the preparation for the competition so we can assign ‘pit rooms’ accordingly.
- All robots must remain powered down or ‘on blocks’ in the ‘pit rooms’. This is to ensure that any remote control conflicts or remote control/autonomous mistakes do not result in your robot zooming off the table and being damaged.
Raspberry Pi at the Core
- All robots must have an operational Raspberry Pi at their core which carries out the majority of the computing effort.
- Other boards, such as an Arduino, micro:bit or other microcontroller may be used on the robot but the Pi must be in overall control.
- Additional pieces of equipment e.g. a games controller, a laptop, mobile phone or tablet may be used to control the robot, but must not be physically attached when competing on the courses.
- All robots must be powered by batteries.
- Mains power may be used for charging battery packs.
- If LiPo batteries are used, any charging must be done inside a fire-proof bag, available from many places that stock the batteries, such as HobbyKing. This is to ensure we don’t have any accidents.
- No airborne robots are permitted, e.g. drones.
- Walking and self-balancing robots are permitted.
- The main chassis (including wheels and protrusions) of competing robots must fit within a 225mm x 300mm footprint. When travelling forward:
- The maximum width should be no more than 225mm.
- The maximum length should be no more than 300mm.
- Attachments may be added to the robot for specific challenges and these may add a maximum 100mm to the front of the robot. The maximum size of the robot with attachments can, therefore, be 225mm x 400mm, as per the diagram above.
- There is no height restriction – but please remember that top-heavy robots may struggle with some of the challenges!
- When adding attachments, the basic chassis, Pi and controller arrangement must remain the same.
- There will be a number of different challenges into which you may enter your robot, the results of which will contribute to an overall score.
- Points structures will be published by Pi Wars to ensure that teams are aware of how many points each challenge is potentially worth.
- None of the challenges are mandatory.
- No points will be earned from challenges not entered.
- There may be some physical requirements for specific challenges – please consult the individual challenge pages for more information.
