timeline: 2026
tech stack: C++, Arduino, 3D Printing, Servo Motors
Overview
A gesture-controlled robotic hand built as a mechatronics project. The hand replicates human finger movements using servo motors driven by flex sensor inputs, demonstrating real-time biomechanical mapping.
Design & Build
The mechanical structure was 3D printed with articulated joints connected via tendons to micro servo motors. An Arduino microcontroller reads analog signals from flex sensors worn on a glove and maps them to corresponding servo positions.
Results
The prototype achieves accurate finger tracking with minimal latency, capable of replicating basic grip patterns and individual finger movements in real-time.
