A vision-guided robot (VGR) is a robot system that comprises a camera, sensors, and microprocessor or computer, with associated software. These robots provide accurate feedback signals about the ongoing situation to the robot controller. They are widely used for appearance inspection, dimension inspection, counting, as well as picking, and positioning. The camera system can be divided into two broad categories, such as 2D and 3D cameras.

2D vision cameras capture an image of an object using a two-dimensional map of reflected intensity. It helps in barcode reading, label orientation, printing verification, and others. 3D cameras enhance utility, flexibility, and velocity to adapt to environmental changes while performing tasks including pick and place.

These robots are used in industries for quality control to check dimensions, angles, color, surface structure, and nearby object recognition. VGRs that use machine vision and image processing technologies have been extensively used in industries, such as automotive, aerospace, metal processing, and others to achieve high productivity without delays.
