Next, through testing, we iterated on the design of the finger to improve key characteristics such as the ability of the finger to spring back to a neutral 90°, the flexibility of the finger to be controlled by the torque of the motors we ordered, and the cable slot size to ensure accuracy while reducing friction/binding. Straps were sewn in a loop at the end of each finger to ensure a clean and stable connection.

After critical connections were established we designed and fabricated the housing to improve the stability and aesthetics of our designs. We took extra care to manage the wiring to improve the cleanliness and consistency of the electronic portion of our project. The design of the handle allows for easy access to intuitively control the fingers without any complication.
