Here's another biped robot, in the shape of a standing owl.

Details are poor, since I used only RIS 2.0 parts, plus a rotation sensor.

This is a COG-Shifting biped.

It uses 2 motors, a touch sensor & a rotation sensor:

Motor A: head oscillating
Motor C: feet turning
Touch sensor: head position

Rotation sensor : legs position

Walking principle is simple:

Bends right

Rotates feet to make a step forward

Bends left

     ...and so on...

This biped can change direction on its own footprints and can

turn left or right.

Rear view:

Here you can see the gearings that make legs turn.

The 40z gear on the left is mounted on the rotation sensor.
