What is our goal 🚀

The EnHands student group aims to develop affordable upper limb prostheses (hand prostheses) for the developing world. We plan to develop a prototype and work together with organisations such as the Naya Qadam Trust, who have experience in providing amputees with low-cost leg prostheses, to help with getting the prostheses to people who need them.

About us 👩‍🔧👩‍🚀🦸‍♀️🧜

EnHands was founded in May 2022 and was officially accredited as a TUM student group in July 2022. The group originates from a group of students participating in the Cybathlon Challenge course and currently consists of students from Mechanical Engineering, Robotics, and Informatics related study programs. Organisationally, EnHands is part of the Munich Institute of Robotics and Machine Intelligence (MIRMI).

V1 Prototype - Technical Specifications

As a starting point, we decided to build a prosthetic hand that is the size of the average woman's hand which can perform the most important grasping types. According to research, these are the ”pinch grasp” and the ”power grasp”, since they enable a person to do most of their everyday tasks such as grabbing tools, cooking or housekeeping tasks.

Parts of the mechanics are inspired by the LN4 hand, but with a deeper focus on anthropomorphic design and patient acceptance.
We use polylactic acid (PLA) due to its lightweight and stiff material properties. 3D printing is our main manifacturing method during the prototyping phase, however in future designs we want to switch to more reliable methods which are better suited for developing nations.
Degrees of Freedom
A 3-DoF thumb, two 1-DoF fingers and a 1-DoF 360° rotational wrist, all of which are actuated passively.
Design Philosophy
Discrete passively actuated grasping positions. Anthropomorphic appeareance. Ridged impact resisted parts. Low maintenance.
