The purpose of the present work is to create a robotic leg for physically challenged person. Using this product person will be able to apparently walk like any normal person. The idea is to make the program govern the motion of leg and control the leg driving mechanism accordingly. This can be achieved using Mega Ardiuno 2560 micro-controller and C++ based embedded system. This Robotic leg is accessed by user friendly keypad which will have the functions like simple walk, sit on chair, stand up and stop. Mechanical motion is carried by using worm and wheel mechanism which is self-locking, motor speed is reduced and produces high torque.
