Image KIT Prosthetic Hand

KIT Prosthetic Hand

A five-finger 3D printed hand prosthesis with an underactuated mechanism, sensors and embedded control system. It has an integrated RGB camera in the base of the palm and a colour display in the back of the hand. All functional components are integrated into the hand, dimensioned according to a 50th percentile male human hand. Accessible via a simple communication interface (serial interface directly or via Bluetooth) or controllable via buttons. Camera and display allow for studies on vision-based semi-autonomous grasping and user feedback in prosthetics. As a stand-alone device the hand allows easy usage in different environments and settings.

Key features:
  • Serial communication and Bluetooth low energy
  • RGB camera and OLED colour display
  • Fast, integrated microprocessor (216 MHz)
  • Adaptive, compliant grasping behaviour
  • I²C interfaces for additional sensors
Possible applications:
  • Sensor application and sensor fusion
  • Semi-autonomous control
  • Prosthetics
  • Grasping and Manipulation
  • Prosthetic user feedback
