Abstract or project description

Abstract Grip manipulation and tactile feedback are vital for daily living, and modern prosthetics often lack these abilities due to cost constraints and the low effectiveness of certain solutions. In this work, the author will have fabricated an open-source robotic limb using a 3D printer and adapted that limb to be usable as a prosthesis. The limb will be controlled by a master glove fitted with flex sensors. The arm will also have force-sensing resistors installed on the tips of the fingers, which will provide a reading on the hand's gripping object. Using the glove and hand readings, the user will receive sensory feedback using haptic motors. The intensity of the haptic motors will be adjusted depending on the reading from the force sensors. The limb will be tested in a small trial, which will test the limb’s dexterity and strength by having the limb hold various objects of various shapes and sizes. The author believes that successfully implementing these features will improve access to low-cost and more functional prosthetic limbs.
