Red Robot v1

Before starting the train project I was working on a red robot using NXT Mindstorms with 3 motors. It's a simple humanoid robot with one motor for each leg and one motor for moving the head. The idea is that the head will balance the weight during walking. Unfortunately I didn't have time to implement walking yet. Just in case I also added a gyro sensor which may come handy for balancing. I will get back to this project in two weeks...

Red Robot v1 using NXT

Because each leg has just one motor I was using large gears and liftarms to transfer the knee rotation to the hip. The arms are fixed because original NXT can only handle 3 motors. Later I'm planning to extend this configuration with third party extensions and more motors.
