The box will be placed on the robot while the robot is in its functional starting position. Control Any means of self-contained control is acceptable. A robot may not spray any material on the ring or on their opponent, or in any way deform the sumo ring. Robots are not allowed to incorporate any flying components or projectiles. You may not electro-magnetically interfere with your opponent, or do anything that alters the function of the other robot or its sensors.
Sticky wheels means any wheels which immediately bond to the ring surface.
Wheels which do not immediately bond, but become sticky over time are acceptable so long as the bond is not permanent and the robot still weighs no more than 500 grams when being lifted. It may also incorporate stealth technology to avoid detection by the other robot. Signals may be used to try to confuse the the other robot's detectors, such as flooding the area with IR, touching the far side of the robot, or convincing the other robot it is at the edge of the ring. Overt attempts to damage the opponent's robot, over and above the expected ramming and pushing, are not allowed. Before competing, each robot must qualify.
