In Guadalajara, researchers have developed a prototype prosthetic arm that could change how amputees adapt to bionic limbs. The E-Redi arm, designed at the University of Guadalajara, allows users to control a range of movements using a single muscle sensor.
Led by Dr Erick Guzmán and supported by the Jalisco State Council of Science and Technology, the team set out to simplify devices that often frustrate users and lead them to give up.
For Alberto Orozco, who was born with a partial limb, it is more than a project, it is a promise fulfilled by his childhood friend Jorge Velazco, now the arm’s mechanical designer.
The 3D-printed device conceals its motors within the forearm and helps train users’ brains to control it more naturally, paving the way for future voice-assisted versions.
