Made by Erector, makers of metal construction kit toys since 1913, this motorized robot has pre-programmed movements and sounds, bringing the robot to life and making it capable of walking, dancing, and actions common toys cannot replicate. The kit has more than 500 pieces and comes with a battery-powered drill which young engineers use to assemble the robot. The drill doubles as the motor that drives the robot's movement and the USB device that connects to a PC for downloading music and pre-programmed movements from the Internet for the other builds that can be made with the kit (a crane and a three-wheeled vehicle). Clear, illustrated instructions help guide children in completing the robot (a process that takes approximately 90 minutes). Includes a USB cable, one electronic drill module, and two additional motors. Requires three AAA and four C batteries. Ages 8 and up. The manufacturer has confirmed that this item meets all U.S. Federal toy safety standards, including safety standards for lead. 13 1/2 H" x 13" W x 18 1/2" D. (4 lbs.)
