A novel approach to control the jointed arm robot by tracking the position of the moving object on a conveyor using an integrated computer vision system

Abstract EN

Computer vision algorithms play a vital role in developing self-sustained autonomous systems.

the objective of the present work is to integrate the robotic system with a moving conveyor using a single camera by adopting a gaussian mixture model (GMM) based background subtraction method.

In this work, a simple web camera is placed above the work cell to capture the continuous images of the moving objects on the conveyor along with a jointed arm robot connected to a microcontroller through the computer.

the position of the object with time and its features are extracted from the captured image frames by subtracting its background using the gaussian mixture model (GMM).

the output images of GMM are further processed by image processing techniques to extract the features like shape, color, and center coordinates.

the extracted coordinates of objects of interest are used as input parameters to the controller to activate the base rotation of a joint arm robot to perform different manipulations.

the developed algorithm is evaluated on an indigenously fabricated work cell integrated with a computer vision setup.
