This study addresses upper-limb dysfunction caused by neurological diseases such as stroke, as well as the limitations of traditional rehabilitation devices, which are often bulky, complex, and poorly accessible for home use. A bilateral upper-limb rehabilitation device is developed to provide a practical solution for home-based therapy. The system is designed using Fusion 360 and integrates an aluminum base, a servo-driven mechanism, and Arduino-based control. It supports circular, rectangular, and personalized game-based interactive training modes, enabling bilateral coordinated rehabilitation. The proposed device is compact and portable, making it suitable for independent use in home environments. Through multiple rounds of experimental testing, the system demonstrates stable motion control, high operational reliability, consistent movement execution, and safety performance. Compared with unilateral rehabilitation systems, the bilateral design enhances inter-hemispheric coordination training, improves patient engagement, and increases rehabilitation compliance. The device shows both clinical value and practical application potential, providing an efficient and enjoyable solution for home-based rehabilitation. Future work will further personalize and optimize the system to meet the needs of different patient groups.
