Artificial Knee Joint System using Arduino Software

Artificial Knee joint System Using Arduino Software

Aims and objectives:

Design and develop an artificial knee joint using IMU sensor and Ardunio
micro-controller

Proposed methodology:

The working method of an artificial knee joint consist of mimicking the movement of

healthy biological knee joint. There is one IMU module attached to the sound leg and it

is connected to ardunio micro controller which connects the gathered data from internal

measurement unit to personal computer. After the data have been initialized, and with

help of programming language and ardunio software, the comparison will be 
implemented therefore, it will determine the rotational direction of DC motor. The motor

module will be attached from one side to prototype and motor drive from the other.

However, the second Arduino micro controller will be controlling the motor functionality

and the connection to the second internal measurement unit. The second IMU will

function as feedback sensor in order to ensure the quality of operation while entire

system is running. Since the first IMU will be attached to sound leg, the first respective

micro controller will be caused in heat-proofing material and will be held on the upper

part of the thigh of right leg. The second micro controller will be cased in heat-proofing

material and held on the upper thigh of the unsound leg. The system has been

constructed in such a matter that protect the patient biological limbs and ensure there is

no skin inflammation throughout the rehabilitation period.
