This is my first human-like robot called "Silver Warrior". He is a 350mm tall of weight about 2kg. He consists of 19 moving joints (2x5 for legs, 2x4 for hands and 1 for head) which are all driven by RC servos. 10 high torque servos ranging from 6.5 to 9 kg-cm are used to provide sufficient power to drive the leg. The control unit of the robot consists of 4 nos. of 89c51 together with a RS 232 wireles module. 3 nos. of 89c51 are programmed to generate signal pulses to control the servos. The remaining 89c51 and the wireless RS 232 module are used for RS 232 communication. The power of the robot consists of a 9v battery for the control unit and a 6v 600mAH NiCd battery for all the joints. The operation time is about 5 minutes. The robot is connected to a PC and controlled by Visual Basic. Data from PC is first transferred to a transmitter via USB and the transmitter transfers the signal to the robot via wireless RS232.
