it I'm trying to add thor with feedback sensor technics, I want to keep the printed parts so far, so I made some addon pieces.
It's just a design at the moment, tell me what you think of it?

I have used so allready existing parts, the feedback pcb comes from makeblock. (Angular sensor v1.0) 360 degrees endless potentiometer.

I made a first design

Added 4 sensors for, two for the tools head , one for the shoulder and one for the elbow.
The base and rotating wrist will have other sensors, working on it.

And this will be the covers on the robot.

I am going the use a mini arduino to connect all sensors to the anolog inputs, and going to add the gripper servo and neopixel light also at it. So just 4 wires will be needed to go to the main board.
Like I said, It will be addons to the already designed thor robot. No need to reprint it. Just some small holes to drill to put every part on it.

They are definitely replacing the photo sensors, the accuracy has to be checked the next comming weeks when I finnaly have build my thor. :-) For the base I have a 5 turns potentiometer with the same gear wheel as the motor. Just the wrist will be a challenging one. There's not much room inside of it. If accuracy will become a problem I will go over to magnetic measuring.

Your robot is becoming very sexy!  Look at these curves! 

How accurate are these sensors? And could they replace the photo sensor mechanism?
