Graduation project entitled: "The Biological-Electronic Man" College of Engineering and Information Technology, Department of Mechatronics Engineering. The Biological Man Project is a humanitarian project that aims to alleviate the suffering of people with disabilities who have amputees as a result of diseases such as cancer, gangrene, and people who have lost feet as a result of accidents or wars. This system works by using a sensor of nerve signals by reading the relaxation of the thigh muscles and based on reading the nerve signals, the controller moves the leg forward and backward in response to these signals and the normal movement of the foot. The designed leg is also equipped with a GSM system to monitor the status of the battery on which the system is running and to track the whereabouts of a person by sending temporary text messages based on the situation.
