At present, the removal the sticks from the mineral feeding lines, as a result of the mineral extraction, is carried out manually or using mechanical equipment, which means a loss of efficiency of the grinding and crushing system, high exposure to the risks associated to the removal of foreign elements of grinding material, this method does not guarantee problems from this cause in the subsequent stages in the grinding and crushing process. Due to the above, a robot system and method have been developed for the removal of sticks from the conveyor belts.The robotic system is composed mainly of an anthropomorphous robotic manipulator of at least 5 degrees of freedom, and a gripping mechanism which is supported by a vision system allowing, in a sequential and programmed way, to remove the sticks. In this regard, most of the problems associated to the safety of the personnel and the productivity of the current manual and/or mechanical process are eliminated.
