Electric Bionic Legs Used Gyroscope And Accelerometer With Fuzzy Method

Prosthetic legs are a tool that is often used by a disabled person who has not legs. It is quite easy to use prosthetic legs for amputated legs in the calf but not with those with disabilities who have amputated their legs in the thigh because they have lost leg joints. There are already a handful of people making conventional prosthetic legs, but because the motion of the knee joint on conventional prosthetic legs only uses a work system of mechanical motion, it is still difficult to use for daily activities, especially in carrying out activities up and down stairs. Then there are also prosthetic legs that use EMG (Electromyography) muscle sensors, but the use of EMG sensors has disadvantages in making them require a lot of adjustments and research for different users, because the feet have the same function namely to walk, so that the movement every human being has the same movement. With this fact, in this journal discussing the development of fake feet using gyro electric sensors, the authors have the idea of using gyro, axelero and heavy sensor sensors in the fabrication of prosthetic feet using the fuzzy logic method. Gyro, axelero and heavy sensor sensors are installed on the lower leg or calf, so that in making prosthetic legs on new uses there is no need to make complicated adjustments. In applying this fuzzy logic method, modeling is made that can simulate a person's movements while walking where the user only needs to swing this fake leg like someone who has whole / perfect legs.
