How about some kind of Game that almost demands that robots interact with each other. For example this year the two teams that climbed on top of each other. Problem was they didn't have too they did it to kind of show off. I always wondered what would happen if robots got smaller and there was more than 4 on the field? Allow better sensors, for example,
CMUcam Vision Sensor, this gem made us so excited we were just about to ditch about every sensor and program we had, but a mentor then pointed out it was not allowed!!! The thing is awsome, cheap, reliable, and would be great but we couldn't use it! I mean if they want us to build bots that will react with the enviroment, why not better sensors? (check out the CMU cams video's) Really, the optical sensors aren't all that great. The ruggedness of this years game is a must. Maybe add random rugged terrain. Every field has different terrain. Now not only do you have to scout other teams you have to scout your field!! Welp thats all i could go on for hours.
