Have the campers join into pairs, 1 as the robot and the other as the robot controller.
The controller must give the robot a unique noise or word. When the game begins, the controllers and robots are spead across the area.
Each controller then turns on their robot at the same time and the robots start walking.
The robots are only allowed to walk in a straight line. When the robot bumps into someone or something, the robot must stop and start yelling its unique noise.
The controller must run to the robot and point it in a new direction.
The robot then begins walking again until it hits something else. The game continues until the campers get bored.
