Neuroprosthetic hand

pinshape

The parts above are designed for the hand of a modular neuroprosthetic arm. The design of this prosthetic was driven by two main factors: low cost and modularity. A majority of the prosthetic arm is 3D printed, keeping costs relatively low, allowing for cheap replacement of parts, letting users alter size, and making it easy for others to build upon the existing design. SOLIDWORKS was used to design most of the arm's components. The hand will contain six DC motors and be controlled by Arduino Micro microcontrollers. The thumb can roll and flex at the metacarpophalangeal joint. The motors are fastened into worm drives to control all movement in the hand. Each of the other fingers uses one motor, and they flex at both the metacarpophalangeal joint and proximal interphalangeal joint.
