I designed IQ as a proof of concept robot.It is made of foam core 5mm thick board with .020 styrene plastic sheet overlays. He is 4.5 feet tall and can telescope its head another 8 inches using a camera tripod with motor drive. There is a windows 8.1 tablet installed on its chest. Power comes from a lithium battery pack for drive wheels and a 12 vdc sla battery for the electronics. The EZB 4 is connected in client mode. It is designed not to tip over with anti tipping brackets beneath the lower frame..The movement speed is moderate for stability. The arms are from a Robosapien that i received that did not work.I gutted the arms and installed 3 servos for each arm .It can rotate its arms ,elbows and open and close hands.
