Robocon 2026

Taking the tree theme to heart, Dam Designs have built the core structure direct from the forest. The ducks have gone but beavers are in.

We’ve been to Robocon again this year, renewing our sponsorship of the Dam Designs team (formerly Little Devils) and their redesigned autonomous self-driving robot. The team is now a mixture of primary and secondary school students and with several years’ experience behind them, they took on 16 teams in this year’s more difficult arena.

Each robot is allocated a quarter of the arena, and the goal is to get as many points as possible by collecting cubes and dropping them in their own quarter of the arena. Bonus points are available for dropping cubes in the smaller “home area” within the quarter, or stacking cubes on top of other cubes. Four green cubes start in the central neutral zone and part way through the competition, higher scoring red cubes start to drop one by one. For full details see the competition website.

Is it a bug or a feature?

In the quarter final, the team pushed a code update to prefer picking up the higher scoring red cubes. Unfortunately it didn’t quite go to plan, and by mistake they coded their robot to ignore the lower scoring green cubes entirely. This resulted in a heart stopping moment at the start of the competition where the robot drove to have a view of the neutral zone and then stubbornly sat still while all the competitors cleaned out all the low scoring cubes. As soon as the high value red cubes were dropped the robot rushed in to collect them and take them home, neatly winning the round.

Whilst this wasn’t the intended behaviour of the code, it turned out to be a very good strategy for winning the round. A debate within the team followed: patch the code to try and get extra points from a green cube, or eat sweets and re-enter the winning robot for the semi final unchanged? The engineering conclusion was WONTFIX and the robot won the semi-final too.

Third place

In the final the team got unlucky; the robot spun the wrong way and spent a very long time staring at the wall instead of looking for a cube in the neutral zone. Whilst the robot very slowly turned itself around, the competing robots picked up the green cubes and collected some points. In the final seconds our team’s robot spotted a red cube and rushed towards it but was powered down by the end of the round before it was able to fetch it.
