To recap, so far in the project, the mechanical design was completed. In addition the design of the instrumentation amplifiers and electromyographic sensors was completed. The Mark 1 design is now in the process of revision after first manufacture revealed some expected defects in the CAD files that were not revealed by simulation.
So far, this have been a great opportunity to hone my CAD skills and practice analog circuit design which I have enjoyed greatly. I am tremendously happy with the design of the fingers and thumb, but may change up palm and wrist geometry to enable better grip. So far from initial fabrication I've found a need for a beefier wrist rotor, larger reliefs for servo cables and rotation limiters on the palm. The next project objectives can be found under the product tab. For materials, I will need to order more 14g servos and op-amps.
