Paper encoders

[gunthercox]

I am interested in making some paper encoders for the robot's shoulder motors. Encoder's are fairly simple and I think this would be a project that would fit nicely with the robot's theme of using recycled and repurposed materials.

• Create printable encoder template
• Create a corresponding Zorg encoder driver
• Publish tutorial and instructions
