Abstract: A robotic system may comprise a first robotic arm operatively coupleable to a first tool. The first tool has a first working end. The system may also comprise an image capture device, a display, and a processor. The processor may be configured to cause an image of a work site, which was captured by the image capture device from a perspective of an image reference frame, to be displayed on the display. The image of the work site includes an image of the first working end of the first tool. The processor may also determine a position of the first working end of the first tool in the image of the work site and render a tool information overlay at the position of the first working end of the first tool in the image of the work site. The tool information overlay visually indicates state information for the first tool. The processor may also change the tool information overlay while the first tool is in a first operational state by changing a brightness of the tool information overlay.

Abstract: An apparatus for trimming uneven edges from drawn and ironed metal bodies, such as cans, and breaking, knurling and discarding the scrap ring. The apparatus has oppositely rotating parallel shafts, one having an axially rigid supporting member, cutter and knurling roller at a free end on which a can is supported and the other having an axially rigid rotating wheel with a blade and knurling member peripherally mounted on adjacent sectors thereof. The blade cooperates with the edge of the cutter which is remote from the free end to trim the edge and the knurling member cooperates with the knurling roller. The members mounted on the first shaft and the teeth of the knurling member are configured to provide superior, relatively trouble-free operation.
