The coordinate-following robot has derived its name from the input process, which uses the coordinate as the comparison factor for its closed-loop control system. An ArUco marker (unique identity given to the robot) has specific properties and usability, making it a primary camera influence. Several characteristics of the robot's positioning relative to the end state can be precisely defined using the ArUco marker. The interface is programmed to get information from the mouse about the desired final stage of the robot. A virtual enables the user to choose the desired halt point for the robot. The robot with an ArUco marker on its top tells the user its current centre of mass's coordinates. Thus, the robot minimizes the difference between its current and desired coordinates. This technology can be widely used in minor unmanned surgeries and space explorations to develop a Morse code for a robot, which the robot and the developer only understand. It also has a wide application with drones and military robots.
