Industrial robots are used especially in sectors where the human body is in danger or is working in extreme conditions. One of these sectors is the forges sector where the manipulating objects are hot, and the vibrations and noise are big. The problem of manipulation the hot parts implies the choosing of the right gripper mechanism in order to obtain the best cooling of it and of the robot itself. The cooling of gripper and robot is realized in the movement phase when no hot payload is present. So, the trajectory of movement is important and also the optimum position of robot with respect to the application positions. The proposed paper is dealing with the subject of moving the base of robot with respect to the application points so that an objective function representing the accumulated heat during a cycle to be minim.
