being able to convert enemies would be awesome to the max!
But what are they gonna do after all robots are converted to the other team?
Ok, here's another thought I had: the ants bring the cubes to the base, the queen builds up the wall. Any robot that aproches the queen is asked a password, if the robot doesn't answer, the queen zaps it with a power command and converts that robot to it's own team.
Now the robots should be built exactly the same. They would have a bicolor LED that would turn eighter Green or Red, depending what queen belongs to. Depending on what color is selected, it will leasten to the proper IR message numbers. The robots should have a claw that can grab and lift a bit a cube so it's not dragging. The queen would be just a bit taller and capable of lifting the cubes to build 2 or 3 cubes tall wall. All robots should have some sensors to detect obstacles and cubes. All robots should be manufactured using cheap components so each doesn't go over $30.
