Low cost shadow function based articulated robotic arm

This paper deals with the design, fabrication and control of an Articulated Robotic Arm which can shadow the movement of a Human Arm by using low cost sensors. In this project, four potentiometers are used to control the motion of the arm while one is used to controls the orientation of the wrist and one more is used for controlling the gripper to form a 5 Degree of Freedom(DOF) Robotic Arm. Servo Motors are used as actuators for building the Robotic arm. The software part of the system is burned on Atmels ATmega328P microcontroller which is preloaded with Arduino Duemilanove Bootloader version 1. The programming is done in Arduino programming environment.
