Our project features a med-tech device designed to restore manual dexterity for individuals with motor impairments, developed in collaboration with the non-profit organization ‘Haifa3D’.
The device, a gauntlet actuated by three servo motors, enables users to perform six fundamental gestures, such as a precision pinch or holding a pen. This project synthesizes several engineering disciplines, ranging from electrical engineering to systems engineering.
The system utilizes an ESP32 microcontroller to govern the motion of the servos, which are connected to the fingers via high-strength fishing lines. A key innovation in our design is the hybrid actuation strategy: the servos actively contract the fingers to simulate gripping, while the passive elasticity of the Haifa3D “Kfafits” structure ensures the hand returns to an open position when tension is released. Users control the device wirelessly through a dedicated smartphone application via Bluetooth, allowing them to easily toggle between pre-programmed grasp patterns. Currently, the prototype operates as a fully standalone wearable unit powered by a portable battery, supporting essential daily actions.
