Complete File Update 7/26/19 Hands, Fingers and Whipple update 6/30/19 Files for hands, forearms, and gauntlets have been thoroughly cleaned and updated on 3/21/19. This analog prosthetic arm device seamlessly integrates into a digital world. By substituting traditional components with modern technology, it eliminates the need for myosensors, Arduino units, motor controllers, and individual finger motors. Instead, one linear actuator (optimized for both torque and speed at 63:1) brings four fingers together toward a fixed thumb. The entire system is controlled by a simple DPDT on-off-on switch strategically placed on the forearm's body side. Switch position directly determines open/hold/close commands. This streamlined approach ensures extended battery life, as it can be easily recharged via an external port. Additionally, operation remains straightforward. Currently, the total cost for each unit is approximately $125. Nine printed parts comprise a complete arm (palm, four fingers, forearm, whippletree, palm cover, and outer cover). Minimal hardware requirements make assembly relatively uncomplicated, comparable to that of a standard Phoenix hand.
