Demonstration of a nurse wearing the JAPET active exoskeleton in anterior view at rest (a) and in posterior view during treatment (b) at Foch Hospital. This device is controlled by a software system developed by the manufacturer. It is designed to adjust the assistance provided by the motors based on the specific task being performed by the user. The system uses sensors placed throughout the exoskeleton to monitor the user’s movements and provide feedback to the software, which then adjusts the assistance provided by the motors in real time. When the user is walking or standing, the system provides assistance to the legs to help reduce the load on the user’s back muscles. When the user is lifting a heavy object, the system will provide additional assistance to the arms to help support the weight of the object. Overall, the control of the motors for different tasks in the Japet exoskeleton is based on a sophisticated software system that uses sensors and feedback to adjust the assistance provided by the motors in real time, combined with user input through a wireless remote control.
