Helping Hand Challenge

The number of amputees in low- and middle-income countries (LMICs) is unproportionally high compared to the western world. Researchers have addressed this challenge exploring 3D printing technology to create low-cost body-powered prosthetic upper limbs. Several notable attempts have shown that these type of prosthetic devices may be possible. However, the initial investment of 3D printers in local communities and the lack of knowledge in LMICs on how to operate and maintain these fabrication systems create challenges in delivering the expected impact.


The aim of the Helping Hand Challenge is to develop a body-powered, prosthetic hand (see video), that is made of low-cost, recyclable and accessible materials (e.g., bamboo) available in the local environment in the LMIC rather than using 3D printing. 


Based on our recent research working closely together with LimbForge and the Enable Community Foundation (non-profit organisation who developed the first 3D printed body-powered upper limbs), this competition sets out to manufacture the best-designed prosthetic hand from low-cost material and develop a series of videos and protocols for local people in need.

All participating teams will be advised throughout by clinicians from developing countries (i.e. India). The best design will be chosen towards the end of the project. The winning team will visit Sri Lanka for two weeks working with local hospital/amputees to improve their design, share knowledge, deliver and validate the prosthetic hand engaging with local amputees.
