A need for a prosthetic hand device has arisen based on the fact that many people lose one of their upper limbs for various reasons. Many systems are available to control prosthetic hands, such as electromyography (EMG) and mechanomyography (MMG). These systems present many problems, including complexity, high cost, and other issues. Voice commands are among the solutions recommended to address these issues. The proliferation of the Internet, voice recognition technology built into mobile phones, and Internet of Things (IoT) technology has facilitated the use of voice commands to operate prosthetic devices. In this paper, robotic prosthetics were controlled using this technology in the context of five different movement classes. This study involved five participants and reports as accuracy rate of 97%.

Rehabilitation robots have become one of the main technical instruments that Treat disorder patients in the biomedical engineering field. The robotic glove for the rehabilitation is basically made of specialized materials which can be designed to help the post-stroke patients. In this paper, a review of the different types of robotic glove for Rehabilitation have been discussed and summarized. This study reviews a different mechanical system of robotic gloves in previous years. The selected studies have been classified into four types according to the Mechanical Design: The first type is a tendon-driven robotic glove. The second type of robotic glove works with a soft actuator as a pneumatic which is operated by air pressure that passes through a plastic pipe, pressure valves, and air compressor. The third type is the exoskeleton robotic gloves this type consists of a wearable mechanical design that can used a finger-based sensor to measure grip strength or is used in interactive video applications. And the fourth type is the robotic glove with a liner actuator this type consists of a tape placed on the fingers and connected to linear actuators to open and close the fingers during the rehabilitation process.
