Last Nov. I built a vex bot with some neighbor kids. We set up a maze and proved that a square bot and Sharp Ir sensors could navigate the maze. Had to take the kit back to the First team before the kids really got going on the navigation algorithms. How about a autonomous maze game. Timed trials through the maze with a 3 minute time max.Would need to open up the allowed sensors to do a maze.
For the human controlled portion, I'd like to See a obstacle course. Have barriers in the middle with a small opening that 1 bot could get through. Have the teams score points by going to the other side, retrieve objects and bring them back to a goal to score points. The small passage in the middle would act as a choke - block point encouraging designs that could traverse over the obstacles.
As far as the vex system, the radios and crystals are a problem. Cheap solution is to use wireless PS2 controls. I've used them with another robot controller on the vex hardware and they work well. Vex has some parts that need to be redesigned.
