The main objective of this paper is to develop and control the length of the extension boom for the automated heavy vehicles, especially in the areas of control systems and robotics. It provides a display screen where the parameter values of swivel arm angle lift arm angle, elbow arm angle and length of the extension boom can be configurable. To deduce which parameters we need to consider that are needed to be modified. Forwarder kinematics are taken into consideration for the building of the algorithm for the automatic prismatic link which is obtained from the Mat lab code. Then final results are tested on DSP system Crane Box.
