PVC Torso Mechanism

Welcome!

Today I will be showing you how to build a PVC torso mechanism, or a universal joint. This is a short tutorial so let's get started!

First you're going to need:

1/4" PVC coupler

1" PVC coupler

(x1) DMS-2000MD Servo (20kg servo)

and a cap from a plastic shelf or a flat cap for the 1" coupler.

Assemble the couplers as shown in the pictures above. All the parts get glued together with PVC glue.

Then drill a hole in the center of the cap. Screw the servo horn to the cap, making sure the servo horn hole, and the drilled hole line up.

Now mark and cut a slot for your servo in the PVC T-Coupler. Make sure the servo is centered with the center of the T-Coupler.

Now attach the servo horn to the servo, screw it to the servo, and enjoy. Now you can attach this mechanism to an appropriate fitting pipe and have the T-Coupler move from side to side.
