You need to know Euler angles in order to define your tool reference frame Besides, in order to define the tool reference frame associated with your end-effector (as in the figure shown below), you would need to calculate the pose of that tool reference frame with respect to the flange reference frame. It is much more efficient to calculate and define your desired pose offline. Of course, you can always jog your robot's end-effector or hand-guide it to approximately the desired pose, but this so-called online programming method is tedious and very imprecise. In other words, you need to be able to program your robot to move its end-effector both to a desired position AND a desired orientation (i.e., to a desired pose). ![]() If you use a six-axis robot arm, like Mecademic's Meca500 used in this tutorial as an example, you are most probably interested in positioning its tool ( end-effector) in various orientations. ![]()
