A pallet building apparatus for automatically building a pallet load of pallet load article units onto a pallet support (SPAL), the pallet building apparatus comprising: a frame defining a pallet building base for the pallet support; at least one articulated robot connected to the frame and configured so as to transport and place the pallet load article units serially onto the pallet support so as to build the pallet load on the pallet building base; a controller operably connected to the at least one articulated robot and configured to control an articulated robot motion, relative to the pallet building base, and effect therewith a pallet load build (BPAL) of the pallet load; characterized in that at least one three-dimensional, time of flight, camera is disposed so as to generate three-dimensional imaging of the pallet support (SPAL) on the pallet building base and of the pallet load build (BPAL) on the pallet support; wherein the at least one three-dimensional camera is communicably coupled to the controller so the controller registers, from the at least one three-dimensional camera, real time three-dimensional imaging data embodying different corresponding three-dimensional images of the pallet support (SPAL) and of each different one of the pallet load article units, and of the pallet load build (BPAL), and the controller is configured so as to determine, in real time, from the corresponding real time three-dimensional imaging data, a pallet support variance or an article unit variance of at least one of the pallet load article units in the pallet load build (BPAL) with respect to a predetermined reference, and generate in real time an articulated robot motion signal dependent on at least one of the real time determined pallet support variance or article unit variance, the articulated robot motion signal being generated in real time so as to be performed in real time by the at least one articulated robot between placement, by the at least one articulated robot, of at least one pallet load article unit and a serially consecutive pallet load article unit enabling continuous building of the pallet load build (BPAL). a frame defining a pallet building base for the pallet support; at least one articulated robot connected to the frame and configured so as to transport and place the pallet load article units serially onto the pallet support so as to build the pallet load on the pallet building base; a controller operably connected to the at least one articulated robot and configured to control an articulated robot motion, relative to the pallet building base, and effect therewith a pallet load build (BPAL) of the pallet load; characterized in that at least one three-dimensional, time of flight, camera is disposed so as to generate three-dimensional imaging of the pallet support (SPAL) on the pallet building base and of the pallet load build (BPAL) on the pallet support; wherein the at least one three-dimensional camera is communicably coupled to the controller so the controller registers, from the at least one three-dimensional camera, real time three-dimensional imaging data embodying different corresponding three-dimensional images of the pallet support (SPAL) and of each different one of the pallet load article units, and of the pallet load build (BPAL), and the controller is configured so as to determine, in real time, from the corresponding real time three-dimensional imaging data, a pallet support variance or an article unit variance of at least one of the pallet load article units in the pallet load build (BPAL) with respect to a predetermined reference, and generate in real time an articulated robot motion signal dependent on at least one of the real time determined pallet support variance or article unit variance, the articulated robot motion signal being generated in real time so as to be performed in real time by the at least one articulated robot between placement, by the at least one articulated robot, of at least one pallet load article unit and a serially consecutive pallet load article unit enabling continuous building of the pallet load build (BPAL).
