You can feel free to ignore this (
), as I probably won't be able to participate, but I personally feel that it would be better to have one robot that everyone must program, instead of allowing them to make their own. It takes some of the challenge out of it if you can add a gazillion (
) sensors around the edges of your robot, instead of having design a way to work with only two sensors. Whatever, you can ignore me.
--EDIT--
At the very least, some rules regarding number of sensors and such should probably be added.
