This is a legal version of a team prop that FTC teams can use that will allow teams to create fast autonomous opmodes without worrying about running over their team prop, or another team's team prop. The team prop is .5" thick, so a robot could roll over it if the robot was already designed to roll over pixels.
According to Game Manual 1, rule part c) "When measured, the Team Game Element should be placed in a self-supporting position inside a measuring tool, in the same manner that it will rest on the Playing Field Floor." This means that although in some orientations, the team element might be illegal, in the starting position, the team element is larger than 3"X3"X3", and smaller than 4"X4"X4" and thus, is a legal team prop. This is better demonstrated in the animation of the team prop on the field https://youtu.be/9DYaDuF5EwA
