Abstract: A robot for emptying a postal machine having a plurality of containers into which the postal items (letters and cards) are delivered and form a substantially ordered stack of items, one on top of another. The robot includes a base structure located on a rectilinear structure arranged parallel to a wall of the postal machine and a columnar structure which is fixed to the base structure and supports a slide slidable vertically on the columnar structure itself. The slide supports a pair of arms which are slidable relative to the slide and have gripper devices at their ends arranged to be introduced into one of the containers to grasp a stack of postal items, to withdraw them from the container and to deposit them on a conveyor belt.
