DEVELOPMENT OF MICROCONTROLLER BASED ROBOTIC ARM

The automatic movement of robotic arm involves a number of parameters, such as knowledge about current position of the arm to the controller, position of the object to be picked, size of the object, weight of the object, nature of the object etc. The controller thus performs a number of computations and accordingly controls the operations of actuating motors involved. In most of the static systems that are presently in use, the sensor nodes used for defining the position of object are fixed at defined distances from the reference position of the arm thus the robotic arm comes to an initial reference position each time after picking up an object. This a main cause of low speed of operation of the robotic arm and hence the system throughput. Finding paths of minimal length between two areas on a three dimensional surfaces is of great importance in many fields such as computer-aided neuroanatomy, autonomous vehicle navigation, geophysics, terrain navigation, etc. The main focus of the proposed work is to develop a dynamic system of robotic arm that will pick-up and place the object using shortest path.
