When a human player steps off of the pressure-sensitive mat they are standing on, that human player's robot is disabled until the human player steps back onto the mat.

The colored triangles are there so that the robot's vision system can find them during autonomous or during regular play. The triangles at the manual loading zones are there also so the human players can see that a robot wants a tetra (by being on the colored triangle). When the robot enters one of these triangles, the human player picks up a tetra, steps off the pad (disabling the robot) and gives the tetra to the robot, and goes back to the pad so the robot can be re-enabled and deliver the tetra to a goal.
