Well, I kinda pushed the camera towards the start of this year's, maybe I can try it again...
How about something that REALLY pushes the envelope on getting (A) more dependency on the whole alliance working together instead of the "strongest robot", and (B) more focus on the higher-end manipulator devices?
How about robots lifting other robots? I remember the one year with the innertubes (2-3 years ago), when there was a bonus awarded to an alliance that could stack their alliance's robots, ie. by lifting them up, driving up on top of them, etc. Why not make that a part of the challenge? Requiring robots to lift or shift each other vertically to reach or manipulate the game pieces (Think Overdrive's overpass, hehe) would make for an interesting challenge.
Also, we should keep the camera systems, now that NI and Sun are on board for technical support (and supportive techniques) and some of the first-year bugs with camera synchronization are worked out. I think that the cRIO and all of its capabilities may finally have the chance of really being put to the test (Can anyone say linear accelerometers?) and that yes, this truly is like a whole new (*cough* season) beginning for the FIRST Robotics Competition. With the bugs fixed.
Oh, that might be another interesting thing... Bugs... ...oops, I better stop before this post goes denim.
