Roboraptor is an impressive mix of advanced artificial intelligence, personality, multiple sensors and realistic biomorphic motion. Designed by Mark Tilden, the genius behind Robosapien, the advanced Roboraptor displays three personalities: aggressive hunter; methodical and cautious; friendly and playful. You'll be amazed as you watch him move his head and neck with realistic biomechanical action. He also has a whipping tail that sweeps back and forth. Control 40 preprogrammed functions using the two-handed remote control or let him move on his own in Autonomous mode. Move him by remote forward and back and watch as he advances toward his "prey." Keenly aware of his environment, Roboraptor uses his infrared vision system to detect motion as well as objects in his path; sonic sensors and touch sensors in his tail, chin and tongue to see, hear and feel where you are and what's in his surroundings. Use the remote to shine a green target "prey" point on a surface and Roboraptor will hunt with intense focus. Measures 30" x 7 3/4" x 11". Roboraptor runs on 6 AA batteries; remote control runs on 3 AAA batteries (order all batteries separately). For ages 8 and older. 90-day warranty.
