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

Coronavirus pandemic

Dear TERRINet applicants and future users,

we sincerely hope that you are staying safe in these challenging times that we are facing at the moment. The current emergency due to the COVID-19 pandemic has deeply changed our lives. The recent and progressive lock-down forced us to reorganize our working routines in smart working modalities and to shut down the TERRINet infrastructures. Therefore, we regret to inform you that Trans-National Access has been suspended until further notice.

However, we would like to reassure you that we will keep evaluating the proposals submitted for Trans-National Access regularly. Indeed, despite access cannot be allowed for a while, the selected users will be queued and access will take over gradually as soon as the situation will allow it. We also inform you that a special application mechanism has been settled in TERRINet to mitigate the delays that will occur due to the COVID-19.

The Open Call no. 4 is currently open: we are accepting proposals under the new mechanism called "first come, first served". Proposals are directly forwarded to the evaluation panel as soon as they are submitted. Proposals submitted closer to the deadline will be dispatched after that. The deadline for the Open Call n.4 will be on May 31, 2020.

Do not hesitate! Get this unique opportunity to be granted with fully-covered access (including travel and accommodation costs) to 15 leading European robotics labs and 100+ best robotic platforms and to get in touch with leading robotic experts. 

For any additional questions, please, contact us at info@terrinet.eu

 Let's take this time of the world calming down to plan our future. 

Stay safe.  

TERRINet team
