The ‘Robot Survival Game’ is a non-destructive robot fighting competition that started 2 years ago in Japan and a few days ago took place for the 10th time. It involves biped, multi-legged, tracked or wheeled robots (or any combination of sorts) that compete in a several scenarios (similar to team games like paintball) ex ‘eliminating’ each other, reach a flag etc. The robots are usually remotely controlled via a camera and the operators may be nearby or even in another city. They also have a toy gun for fighting but they ‘destroy’ each other in a very clever simulated way. Each robot carries a small container made from fragile aluminum foil. A light sensor inside the container is kept in the dark unless a bullet from an opponent punches a hole in it. Then the light sensor detects it and it acts as a kill switch and the robot is ‘dead’. It is a smart way of keeping the entertainment (and the drama!) high without destroying the actual robot. You can find much more information and a lot more videos at IKETOMU’s blog.
