Winner of the prestigious Nuremberg Toy Innovations Award, this is the first fully-animatronic simulacrum of a one week-old dinosaur (a Late Jurassic period Camarasaurus.) It is programmed with distinct behavior routines that respond differently to stimuli, creating a one-of-a-kind personality for each one made. It has a sophisticated sensory system comprised 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, all of which form a biomechanical skeleton that delivers smooth, natural movements. The dinosaur's unique accelerated lifespan passes through three distinct phases; when you first turn it on, it acts like a hatchling for the first 15 minutes. For the next two hours, it acts like an infant by exhibiting hunger. For the rest of its life, it acts as a juvenile, and is fully-responsive to light, sound, and touch. Its outer skin is Krayton rubber, and the young reptile's rechargeable battery provides one hour of operation and requires four hours for a full recharge. Ages 8 and up. The manufacturer has confirmed that this item meets U.S. Federal toy safety standards for lead. 20 3/4" L x 6" W x 7 1/2" H. (3 1/2 lbs.)
