The project deals with the designing, modeling and simulation of a 2-link robotic arm. Forward kinematics, backward kinematics and dynamic modeling of robotic arm are done. The purpose of our robotic arm is to paint a wall of specified area. We have mounted our robotic arm on a moving base which moves in horizontal direction and robotic arm moves in vertical direction. The vertical movement of the robotic arm follows a straight line to maintain same distance from the wall. Programming has been done using PIC microcontroller. Limit switches are used to control the vertical and horizontal motions of our robotic Arm. Gears are used to maintain desired speed. Spring is also used to control the speed of Arm
