Automatic batch manufacture is one of the most promising future direction in the field of computational robotics with the smart assembly system. In this paper design of improved vision sensing manipulator to recognize desired components in unstructured assembly system is presented. The proposed sensor based intelligent robotic manipulator can be used to solve high-dimensional problems manipulate and grasp objects in unstructured environments. The scheme is composed of an intelligent robotic end-effector control system to proficiently supervise the end-effector towards the object to be manipulated in the same workspace. The proposed scheme is developed with sensors such as vision and ultrasonic sensors, which is installed at the end-effector of the robot to recognize the object. Experimental work on sensor has been carried out to demonstrate the integration robot manipulator for accomplishing the desired industrial tasks. © 2015 IEEE.
