One robot detects objects using infrared rays, the wake-up robot is sensitive to light and the third robot is operated by any TV remote control. A separate circuit and body are supplied for each robot:  just fix the selected circuit onto the robot base and add the corresponding transparent body. Includes one (1) pre-assembled PC board and three (3) robot bodies, which allows you to build three (3) different robots, one at a time.
