This electromechanical biped was built using R/C electronics and tongue depressors.

The biped uses six “9 gram” servos, one at each joint: ankle, knee, hip. The servos are driven by a 6 channel Spektrum compatible receiver. Everything is powered by a 2s 350 mAh lipo battery.

A JR 9303 R/C transmitter transmits signals to the receiver. An Arduino generates a PPM pulse stream that drives the trainer port of the 9303. All the motions are generated by a program running on the Arduino.

The program uses one of the timers on the ATmega328 to generate the proper timing. The program fields interrupts from the timer and drives an output pin high and low.

The Arduino takes commands from the PC keyboard.The program implements the actions: “bow”, “squat”, “rock”, “jump”, and “walk”.
