Abstract: A hand controller apparatus for controlling a tool in a robotic surgery system has a body with a proximal end and a distally located interface end that can be coupled to an input apparatus for controlling a surgical tool. The hand controller apparatus includes a control lever attached to a pivot joint proximate a side surface of the body and extending along the body and away from the proximal end, the control lever being laterally moveable relative to the side surface of the body about the pivot joint. The control lever includes a tail region adjacent to the pivot joint and a paddle region connected to the tail region and extending toward the distally located interface end. The tail region includes an inner surface facing the body and an outer surface opposing the inner surface, and at least part of the outer surface of the tail region is outwardly curved.

Abstract: Example systems relate to recoater movement. A non-transitory machine readable medium may contain instructions executable by a processor. The instructions may include instructions to change an action of a recoater in response to a determination that the recoater has reached a first location of a build area comprising build material. Instructions may further include instructions to lift the recoater in response to a determination that the recoater has reached a second location of the build area. Instructions may additionally include instructions to move the recoater over the second location at the lifted position, wherein the second location includes a build-up of the build material.

Abstract: Some examples include a fusing system for an additive manufacturing machine including a carriage movable across a build zone along the x-axis, a thermic source mounted to the carriage, and a roller mounted to the carriage adjacent to the thermic source. A longitudinal section of an exterior surface of the roller is exposed to indirect heat from the thermic source. The roller is controlled to rotate during and outside of a spreading operation of the build material. The carriage is to maintain the roller within a radiative heat transfer area of the thermic source.

Abstract: An example three-dimensional printing system includes a first carriage, a second carriage, and a synchronization controller. The synchronization controller is coupled to the first carriage and the second carriage to synchronize movements of the first carriage and the second carriage. The synchronization controller is to avoid interference between the first carriage and the second carriage.

Abstract: Examples disclosed herein relate to printhead indexing. An example method can include rotating a crank arm connected to a coupling bar. The method can include moving a print sled translationally by the coupling bar, where the print sled may be located in X, Z, and Y orthogonal dimensions. In this example, the print sled may be translationally moved to one of a number of index positions by the coupling bar in response to rotation of the crank arm, where the number of index positions are separately located in a Y dimension with the same Z dimension.

Abstract: Described herein are techniques that facilitate the prediction of the end-of-life of a direct current (DC) motor of an apparatus. The described techniques include tracking end-of-life indicative motor-response values of a DC motor based on an applied-voltage value at its corresponding specified speed of the DC motor when the motor is engaged, in response to the determination that the tracked values exceed a range of acceptable operational values, a health-status notification regarding that DC motor is generated. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A 3D printer includes a movable platform, a motor to vertically translate the movable platform during an additive manufacturing process executed by the 3D printer to form a product on the movable platform, a linear encoder strip attached to the movable platform and a linear encoder reader disposed to read the linear encoder strip as the linear encoder strip moves relative to the linear encoder reader. A control circuit is to drive the motor based on an output of the linear encoder reader.
