Pleo has a impressive sensory system. The robot's sensor array is made up of a color camera, two sound sensors, two infrared sensors, 14 servos, 106 gears, eight touch sensors, an orientation sensor, and four foot switch sensors.
The animatronic dinosaur is responsive to light, sound, and touch making more autonomous and interactive than most robotic toys on the market.
The creator is a famed inventor Caleb Chung, who insisted that Pleo's bio-mechanical skeleton and servos deliver natural movement. Watch this video clip and I think you will agree he has succeeded.
Pleo is the Winner of the prestigious Nuremberg Toy Innovations Award.
