Project Summary

The human body is a remarkable piece of biological machinery, and our limbs are no exception. The loss of a limb causes disability and it renders a person immobile. This leads to a poor standard of living and additional dependency on a healthy individual. Prosthetic limbs are available to restore some of the capabilities or to reduce the dependencies of amputees. Although prostheses have been commercially available but, most of these are passive in nature and consequently, their mechanical properties remain fixed with walking speed and terrain. Recently, the active prosthetics are replacing these passive ones as it plays an important role in rehabilitation.

The project is to develop and design an ankle-foot prosthetic for which we will build a device that can convert EMG signals from healthy leg muscles into a control signal that will direct the ankle position of an ankle-foot prosthesis. 

The converting device provides a detectable signal for classifying data, and it consists of pre-processing and signal conditioning stages. The data will be classified using Artificial Neural Network on Mathworks MATLAB that will help in training. The trained data will be used to control the actuator that is Ankle-foot prosthetic which will be designed and fabricated through 3D printing. This EMG controlled Ankle foot prosthetic will help the amputees in daily life activities due to its ability to imitate some of the ankle movements.

Project Objectives

• To create a three-channel device which can collect raw EMG data from healthy muscles and can transfer it to pre-processing stages.
• To construct a signal conditioning circuit which can convert raw EMG data into the processable form.
• To build an algorithm which can classify at least two movements from the EMG data of healthy muscles.
• To design the mechanical structure for 3D printed ankle-foot prosthetic which can carry the above-mentioned deliverables.
• To design and develop an EMG controlled ankle foot prosthetic which can replicate the movement of the human ankle with the help of motors through a classification device.
