Stroke is a physical disability disease, which affects the upper extremity motor system. To support post-stroke motor rehabilitation, research on IoT-based elbow exoskeleton therapy devices that help elbow therapy with flexion and extension movements. The therapy device uses DS-SERVORD5160 as the main driver to provide flexible movement. By using the ESP32 microcontroller control system equipped with a Bluetooth connection that is connected via the MIT App Inventor application from a smartphone that can be done at home to increase the effectiveness of post-stroke recovery. The results of this study with low (20°), medium (40 °) and high (60 °) modes by providing a maximum load of 2 Kg. It can be concluded that the device shows stable performance in low (20 °) and medium (40 °) modes, but in testing with high mode (60 °) with a load of 2 Kg there is a decrease in servo performance which is indicated by the instability of the servo movement which shows an angle of 56 °.
