Design and implementation of upper-limb rehabilitation device based on embedded system

This paper is mainly on designing a wearable device for upper-limb rehabilitation by the integration of network communication, mechatronics design, interactive webpage, and database management. The developed function modules include a multi-dimensional mechanical structure, sensor and driver circuits, database, and interactive interface. In the design of mechanical structure, 3D printing is used to product some key components. The signal acquisition and analysis, information transmission, and controller design are implemented in a Raspberry Pi based embedded kernel. From system integration and testing, the required functions are all verified.
