Active Exoskeleton Finger Rehab Device
Build an Active Exoskeleton Finger Rehab Device with ESP32 Physiotherapy Control
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Regain finger mobility with a custom-built active exoskeleton. This kit lets you assemble a wearable device that gently flexes and extends fingers under programmatic control, mimicking the repetitive motion exercises used in physiotherapy for stroke recovery, tendon repair, or arthritis management. The ESP32 drives four high-precision servo splints, while FSR pressure sensors monitor contact force at each fingertip to prevent over‑extension and adapt movement in real time.
What You'll Build
A lightweight exoskeleton that straps onto the hand and guides each finger through a programmed range of motion. The MPU6050 inertial sensor tracks hand orientation for logging therapy progress on the 0.96‑inch OLED. With closed‑loop servo control, the system ramps force gently until the preset pressure threshold is reached, ensuring safe, repeatable exercises. After assembly, you’ll have a functional prototype ready for research, academic demonstration, or personal use in mobility assistance.
What You'll Learn
- Programming closed‑loop servo control using FSR force feedback
- Interfacing the MPU6050 for real‑time motion tracking and angle feedback
- Designing and calibrating a wearable biomechatronic system
- Implementing a customisable physiotherapy protocol on the ESP32 with OLED interface

Who This Kit Is For
This advanced kit suits final‑year B.Tech/M.Tech students in biomedical, electronics, or robotics engineering who need a capstone project with direct clinical relevance. Researchers at IITs, NITs, or medical institutions prototyping low‑cost rehabilitation devices will find the pre‑integrated sensing and actuation invaluable. Makers with prior embedded‑systems experience who want to build an assistive device for a family member or compete in the Smart India Hackathon will appreciate the ready‑to‑assemble, validated design.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion provides real‑time debugging; you can also reach us on WhatsApp for direct guidance on this specific exoskeleton project.
How do I adjust the splints for different finger sizes?
The 3D‑printed frame is designed with adjustable Velcro straps and multiple mounting points, allowing a snug fit on most adult hands—the AI guide shows you how to fine‑tune it.
Can I reprogram the physiotherapy motion sequences?
Yes, the ESP32 is fully open. The included code examples cover several therapy modes (passive, assistive, resistive), and you can modify them to match a therapist’s protocol.
Is this kit cleared for clinical or home medical use?
This is a prototyping platform for research and education, not a certified medical device. Use it in supervised settings or as a basis for further development.
Four servo-actuated finger splints with FSR pressure feedback run a physiotherapy motion program from an ESP32.
