  • Publication number: 20240082095
    Abstract: Disclosed is an exoskeleton-type rehabilitation robot system, including: a body part provided on a chair in which a user sits and provided with a robot arm capable of moving left or right based on the user seated on the chair; a conversion part configured to convert a position of the robot arm with respect to the body part; a driving part configured to articulate the robot arm with respect to the body part; and a controller configured to detect a change in a position of the robot arm and control a left or right driving mode of the driving part according to the position of the robot arm. In accordance with such a configuration, the exoskeleton-type rehabilitation robot system of the present invention is provided integrally with a chair, thereby having excellent space utilization. In addition, the user's initial preparation for rehabilitation training is simple, which can improve efficiency.

  • Patent number: 10160121
    Abstract: A module connection system is configured by connecting a plurality of modules by means of connectors. The modules include a base module, a first module and a second module, and the connectors include a first connector and a second connector. The base module transmits power and signals provided from a driving source, the first module is electrically/mechanically connected to the base module by means of the first connector, and the second module is electrically/mechanically connected to the first module by means of the second connector. The first connector includes a larger number of connection terminals in comparison to the second connector in order to transmit power and signals from the base module to the second module and simultaneously supply power and signals required for the first module.
