For patients with above-elbow amputations due to trauma, congenital limb differences, or medical conditions requiring surgical amputation, performing daily tasks like food preparation can be challenging and often requires assistance. This project develops an intuitive, muscle-controlled prosthetic arm that restores independence in the kitchen by enabling users to flip pancakes through natural bicep muscle contractions.


This technology addresses the critical gap in functional prosthetics for upper-limb amputees, where traditional prosthetics often lack the dexterity and intuitive control needed for complex daily activities. By utilizing residual muscle signals, the system promotes neuroplasticity and maintains muscle memory pathways, potentially improving long-term rehabilitation outcomes.
"The design prioritizes user dignity and psychological well-being by restoring the ability to perform basic cooking tasks independently, promoting autonomy and self-sufficiency in daily life."
