Yes figuring out the encoder interface would be the most work. It dosent look like there are enough pins for 6 axes of sinusoidal quadrature signals plus index. So it could be all digital interface. I wonder what the typical acuracy and resolution is? Yeah now that I think about it more it seems like quite a project. Would probably have to disassemble a joint to see the encoder.
