Important Notice
The prosthetic project is currently on hold due to high certification costs.
Your support for the Yeah Hand – Robotic Version will help us generate the funds needed to bring the prosthetic version to life.
Together, we can make it happen!

Wrist detail
The wrist has a limited range of +90 -90 degrees.
The red ball pin is rigid and can slide along the red canal, ensuring the range limitation.
The blue ball bearings are soft material (TPU 82A). They exert a certain amount of pressure on the outer ring, keeping the wrist firmly at its current position, but still allowing the user to rotate it by applying a stronger torque.
Components
MCU: ESP32 DevBoard
EMG Sensors: DFRobot-EMG-Sensor
