Abstract
A vision-guided alignment system to align a plurality of components includes a robotic gripper configured to move one component relative to another component and a camera coupled to a processor that generates an image of the components. A simulated robotic work cell generated by the processor calculates initial calibration positions that define the movement of the robotic gripper such that position errors between the actual position of the robotic gripper and the calibration positions are compensated by a camera space manipulation based control algorithm executed by the processor to control the robotic gripper to move one component into alignment with another component based on the image of the components.
