Motion is transmitted to the end effector via toothed belts. The graphs show which drives need to be activated to produce an end effector motion in a given direction. If it is necessary to approach a large number of positions this naturally requires freely programmable positioning axes. The size and position of the working area are governed by the dimensions of the motion components selected. This principle can be used for both vertical configurations wall gantries and horizontal configurations cross-slide units . The choice of linear guides will depend on the forces involved. The end effector can be any one of various devices such as a spray gun power screwdriver power wrench drill spindle labeller or inspection camera. As the drives are fixed and the toothed belts have very low mass highly dynamic motion sequences can be achieved. For pin-point working it is advisable to fit additional clamps devices to the slide or horizontal effector guide. Suitable components Positioning drive DGE. .
