Aim of the challenge
To defuse as many mines as possible within the time limit.
Remote control or Autonomous.
5 minutes with an additional 2 minutes at the start for any calibration for autonomous robots.
- Robots will be placed in the “bottom, left” corner of a raised, walled arena approximately 1600mm x 1600mm in size. Walls are 30cm tall above the base.
- The arena will be split up into 16 square zones (4×4). These zones will have as their floor pieces of white, opaque perspex.
- A single, random square will be lit up in red. The robot must visit the square in question and stop, motionless for 1 second with some part of the robot over the square. The mine is then considered defused, the Judge will click a remote button and the next, random square will be lit up, and so on.
- This challenge can be tackled either using remote control or autonomously, for example using a combination of a high-mounted camera and/or light sensors.
- Here are photographs of a sample perspex plate, both lit and unlit. Please note that due to white-balancing, the white appears slightly blue-grey, but how it’ll appear to an on-robot camera (if your attempt is being done autonomously) is something you’ll need to be able to calibrate on the day. There will be a calibration sample available to use to set-up your camera, if you are attempting the challenge autonomously.
No ranking points will be awarded for this challenge – but the points you can accumulate are comparable with other challenges.
- 55 points will be awarded for each zone correctly visited.
- 150 additional points will be awarded for visiting 10 or more zones.
- 150 points will be awarded for attempting the challenge autonomously.
- 15 points will be awarded for each zone correctly visited.
- 100 additional points will be awarded for visiting 30 or more zones.
Each rescue will be penalised as follows. There is no limit to the number of rescues and it is not possible to achieve negative points for the challenge.
- 5 points will be deducted for each rescue of an autonomous robot
- 20 points will be deducted for each rescue of a remote-controlled robot.
