I was on an FTC team in 2011 and though we didn't have any problems I know why this is caused and how to fix it. The friction between the floor tiles and the robot wheels cause static electricity. The easiest way to fix it is just to do a wire that is crimped into a crimp terminal which is bolted to your robot frame. As long as the wire is dragging on the flood it will keep your robot relatively grounded.
