Robotic freehand drawing using visual feedback

This paper presents a novel automatic control of a robotic arm using visual feedback. The proposed technique makes use of the natural human phenomenon of sight for observing the position a moving object. Instead of a measuring device to obtain the feedback a simple imaging device is used to track the position of a 2-degree-of-freedom robotic arm. Free hand drawing is selected as an application in this paper. Initial results show a promising behavior to be used for advanced systems employing complex control strategies.
