Prosthetic Arm
Converts arm rotation to gripping motion

WHAT

  • Designed and prototyped a prosthetic arm to convert arm rotation into a grasping motion

  • Developed 2 mechanisms to achieve this conversion : leadscrew and pulley

HOW

  • Designed assembly parametrically in Fusion360, to allow for different configurations of arm sizes for each user

  • Implemented springs to achieve underactuated grasp (actuated DoF < DoF of motion)

  • Surveyed arm sizes among age groups 18-50 to determine ideal link-lengths for prosthetic arm

RESULTS

  • 1 degree of freedom drove 5 digit grasping motion, with grip strength sufficient to hold 1kg

  • ​Patent process for this implementation is ongoing
