I just built a mini-sumo ring and finished (I think) the firmware in my MarkIII to run in it. I plan on bringing them to the meeting and if anyone has a robot they want to fool with it might be interesting to see what happens. I have never seen a mini-sumo contest and so far have succeeded in pushing blocks out of the ring but nothing else. So far none of the cardboard boxes have succeeded in pushing the robot out! Anybody have anything that might do it?
