Front view of torso.

Pan/tilt servo added.

Low profile axis set for the shoulders.

This is the bearing set up, you have to put these together, I have used ceramic grease in the grooves to help with lubrication. Pop the top on and bolt it up.

Shoulder section being assembled, Servo horn replaced by the large 3/4 white gear.

Another view of the shoulder section.

Brackets for the next shoulder section.

Two pieces bolted together.

A pair, left and right shoulder sections.

Shoulder angle brackets with bearings.

Brackets bolted together, These will form the shoulder sections.

Two lexan rings, These are spacers for the shoulder gearing.

Shoulder sections no constructed showing 3 servos each side.

Connector hub attached to metal servo disc.

Alloy T6 tube fitted, these were experimental to see how they worked being long, they wil be reverted back to 25mm length.

4 x 4 truck shocks for the torso, These help take the load of the forward and back motions.

Close up of shoulder.

Shoulder pic again.

This gearing system helps ofload the shoulder/arm.

Ball race fitted to bracket for wrist rotation.

I am trying another degree of movement here in the hand/gripper, this servo is behind the wrist rotation servo, This will be removed, I just want to check it out to see if the upper arm servos will lift it.

Rear pic of HR645 servo and 25mm alloy tube.

I pair of wrist brackets with hubs.

This setup has an extra degree of freedom, just experimenting here, this will be removed and the short version added.
