“…In medical, manufacturing, exploration, and military tasks that require teleoperation or telerobotic manipulation with a processing tool, the remote control of laser processing tools would typically be relatively more accurate, flexible and safe compared with a mechanical tool. This feature has been realized, for instance, in cases of tissue welding, chemical detection (Yoo et al, 2010) and laser metal welding (Gonzalez-Galvan, Cruz-Ramirez, Seelinger, & Cervantes-Sanchez, 2003;Chuen Leong, Teck Chew, Thi Anh Ngoc, Yang, & Chen, 2010;Li, Gao, & Wu, 2007). In the latest, a new intuitive method for robot tool path teaching in augmented reality (AR) environment was developed and tested for robot laser welding application.…”

“…A laser pointer fixed at the robot's tip served both as a guide during the teleoperated task, and as the first indicator of the current holding position. Work piece positioning and objects mapping for industrial robots' tasks were performed by projecting laser spots over the workpiece, which later allowed gathering information about the workpiece geometry with a multi-camera system (Gonzalez-Galvan et al, 2003). A mobile robotic manipulator that can grasp objects previously marked with a laser pointer by a human operator was developed (Young Sang, Cressel, Jonathan, & Charles, 2008).…”

“…In general, the geometry of such a surface is not known in advance, so the visual features over the workpiece are used for determining such a geometry. Laser spots are used herein to produce visual features [10], as they have the advantage of not producing a permanent mark on the surface while enabling camera-space detection using relatively simple imageanalysis algorithms.…”

“…For instance, in [2] the use of a limited number of sensors combined with mirrors, is presented. Other approaches [3] consider the use of multiple cameras or the use of sensors mounted on top of pan/tilt units [4]. In this paper, these two strategies are presented in the case of positioning and path-tracking maneuvers over large surfaces.…”
