The aim of this study was to design and develop a remote-controlled electric hand consisted of flex sensor, gloves, Zigbee wireless transmission, Arduino Microcontroller, and a 3D printed hand. This remote-controlled electric hand can be used for rehabilitation treatment and prosthetic hand. In this study, two general directions of application were presented: the function of robotic hand and the function of training. The function of robotic hand allows the 3D printing robotic hand could be directly controlled through the data glove, making the 3D printing robotic hand to be another human hand. Three training modes are designed in the function of training to satisfy the demands from different patients. The patients are able to play the interactive training game through the 3D printing robotic hand and the data glove in the rehabilitation system, and to finish the rehabilitation while having fun in the training game, speeding up the recovery. In this study, the microcontroller Arduino was used to completed all the hardware and software to reduce costs and achieve the concept of interactive rehabilitation robot hand, allowing the patients to be able to make the rehabilitation of hand function through the data glove. The system of wireless humanoid robotic arm with function of human hand rehabilitation is well-designed.
