The ARM2u biomedical engineering team from the Barcelona School of Industrial Engineering (ETSEIB) has developed an innovative low-cost 3D-printed transradial prosthesis, which is an alternative to conventional prostheses. Comprised of 15 students from various engineering disciplines, the team has been working tirelessly since 2018 to create a fully functional robotic arm that responds to the user’s nerve impulses.
The ARM2u prosthesis employs myoelectric control, taking advantage of the natural electrical signals produced by muscle contraction. Using EMG sensors, it collects commands from the patient’s muscle contractions and translates them into signals that the microcontroller can understand and use. The design can be customized to fit individual arm sizes and features a reduced weight for comfort.
Having already developed two prototypes, the team is focused on further refining its technology. They are incorporating artificial intelligence (AI) techniques for myoelectric control, allowing for greater adaptability of the prosthesis. Additionally, they are working on integrating a hand with fingers into the next iteration of the prototype.
The ARM2u team aims to bring their prosthesis to market at a significantly lower cost compared to existing models, offering an affordable solution for people with limb disabilities. Produced using PLA plastic 3D printing techniques, the prototype is cost-effective and easily reproducible.
The team’s efforts have earned them a place in the prestigious Cybathlon 2024, the ultimate platform for testing prosthetics. During this event, people with physical disabilities will perform everyday tasks using various prosthetic designs. ARM2u will be the only representative from Spain, showing its advanced technology and arousing the interest of the audience and the participating companies.
looking for collaborations
To further their mission, the ARM2u team is actively seeking sponsors to support their project and assist in the commercialization of the prosthesis. They emphasize that the support of sponsors is crucial to improve the technology, expand its functionalities and guarantee adaptability for end users. In addition, the team is looking for new wearers to assist during the design and development process, allowing the prosthesis to be tested in the real world.
With its innovative, low-cost robotic arm, the ARM2u team is poised to make a significant impact on the lives of people with limb disabilities. By leveraging cutting-edge technology and their multidisciplinary expertise, they are driving advances in prosthetics and paving the way for a more inclusive future.
