Wrist rehabilitation device.
A wearable mechatronic glove for post-stroke hand rehabilitation. Designed, printed, and programmed from scratch. Here's how it works.
After consulting with a hospital department head, I identified a gap: passive rehabilitation devices are too rigid or inaccessible for home use. REHABit bridges that — the user sets a target angle in degrees on the Nextion display, and the ESP32 drives 2 servo motors through that range of motion repeatedly.
The goal was a device that could be manufactured for under €80 and used without clinical supervision.
2 Servos,
Nextion Display.
An ESP32 microcontroller sits at the centre, receiving the target angle from the Nextion touchscreen and driving 2 servo motors via PWM through the programmed range. The firmware executes the motion loop until the session is complete.
All electronics are housed in a 3D-printed PETG enclosure designed for tool-free access and field serviceability.
Fusion 360,
Printed in PETG.
Every structural component was modelled parametrically in Fusion 360 — tolerances set for FDM printing, assembly constraints driving the joint geometry. The knuckle joints use a living hinge design that survived 3,000+ cycles of testing without delamination.
Sliced in PrusaSlicer with custom supports and 40% gyroid infill for the load-bearing chassis sections.
