Disclosed embodiments include a gantry assembly that has (i) a moveable carriage with a laser head affixed thereto and (ii) two sides (moveable subassemblies) that are connected by a joining subassembly. One side of the gantry has two motors: (i) a first motor (x-axis motor) that moves the carriage along a first axis (x-axis) between the two sides of the gantry, and (ii) a second motor (y-axis motor) that moves the gantry along a second axis (y-axis) perpendicular to the first axis. In some embodiments, the gantry assembly also includes a drive shaft (or alternative drive mechanism) operated by the second motor (y-axis motor) to facilitate movement of the two sides of the gantry together along the second axis (y-axis).

A robotic system for dynamic controlling the movement of a mobile robot is presented. The robotic system includes a multi-level transport system arranged in an xyz-space. The multi-level transport system includes a plurality of magnetic tracks configured to allow movement of the mobile robot in at least one direction in the xy-plane. The multi-level transport system further includes a plurality of transfer mechanisms configured to change the direction of the mobile robot in the xy-plane, and to allow the movement of the mobile robot in a direction along the z-axis, each transfer mechanism defining a transfer node in the multi-level transport system. The robotic system further includes a control system configured to dynamically control the movement of the mobile robot in the x,y,z direction at one or more transfer nodes of the multi-level transport system, by dynamically activating a corresponding magnetic track or a corresponding transfer mechanism.

This application is directed to a medical instrument with a hollow shaft, an actuating unit at the proximal end and an instrument tip with an instrument at the distal end, wherein the instrument can be actuated via an actuating element in the shaft, the element being in an connection with the actuating unit and the instrument tip being pivotable via a joint mechanism, the joint mechanism having pivoting members connected with a proximal-side drive via steering wires running in the direction of the shaft in such a way that movement of the proximal-side drive causes a corresponding movement of the distal-side pivoting members and a pivoting of the instrument tip and wherein the proximal-side drive includes a spatially adjustable disk on which the steering wires are mounted. In order that the steering wires may be controlled precisely and reproducibly, the drive for the spatially adjustable disk is a motorized drive.

The present application discloses a mechanism to adjust backlash in a rack and pinion powertrain assembly. The mechanism to adjust backlash includes a mounting frame having an opening defined therein to receive an operative end of a drive assembly, a shoulder fastener positioned through a first complementary set of holes at a first end of a mounting flange to movably couple the mounting flange to the mounting frame, the fastener being fastened in a manner such that the mounting flange and drive assembly have freedom to pivot about a longitudinal axis of the first complementary set of holes, and an adjustable length coupling device having a first end coupled mechanically to the mounting plate and a second end coupled mechanically to the mounting flange at a location substantially opposite the first end of the mounting flange.

Provided is a robot. The robot includes a main body provided with a traveling wheel, a seat base coupled to an upper portion of the main body, a seat pad configured to cover the seat base at an upper side of the seat base, a pair of arm supporters connected to both sides of the seat base, respectively, and a pair of moving mechanisms disposed between the seat base and the seat pad, the pair of moving mechanisms being configured to allow the pair of arm supporters to move forward and backward.

A robotic surgical tool includes a drive housing having first and second ends, at least one spline extending between the first and second ends and including a drive gear that rotates with rotation of the spline, and a carriage mounted to the spline. A closure tube extends from the carriage through the first end and has an end effector arranged at a distal end. An activating mechanism is housed in the carriage and includes a driven gear coupled to the drive gear such that rotation of the drive gear rotates the driven gear, and a carrier arranged at a proximal end of the closure tube and coupled to the driven gear such that rotation of the driven gear moves the carrier and the closure tube axially along a longitudinal axis of the closure tube. Moving the closure tube along the longitudinal axis closes or opens end effector jaws.

A manipulator including a shaft driven by a first motor, a rotatable unit, a linear slider, and a gripper is provided. The rotatable unit is coupled to the shaft, wherein the rotatable unit rotates with rotation of the shaft. The linear slider disposed on a first surface of the rotatable unit configured to slide from an initial position proximate to an outer edge of the rotatable unit to intermediate positions and to a final position proximate to a center of the rotatable unit. The gripper coupled to the linear slider to facilitate movement of the gripper along a first plane defined by the first surface of the rotatable unit.

Connector assemblies for connecting a robotic arm with a medical end effector are disclosed. An example apparatus for connecting a robotic arm with a medical end effector may include a connector housing. An actuation mechanism may be disposed within the connector housing. The actuation mechanism may include a plurality of linkage members and a gear assembly coupled to the linkage members. Each of the plurality of linkage members may be configured to shift between a locked configuration and an unlocked configuration. At least one of the plurality of linkage members may include a first linkage member having an end region. A roller member may be disposed adjacent to the end region of the first linkage member. An actuator may be coupled to the actuation mechanism.

A refuse vehicle includes a chassis, tractive elements, a lift apparatus, and a reach assembly. The tractive elements couple with the chassis and support the refuse vehicle. The lift apparatus includes a track and a grabber assembly. The track includes a straight portion and a curved portion. The grabber assembly releasably grasps a refuse container and ascends or descends the track to lift and empty refuse into a body of the refuse vehicle. The reach assembly includes an outer member, a first extendable member, and a second extendable member. The first extendable member is received within an inner volume of the outer member and translates relative to the outer member. The second extendable member is received within an inner volume of the first extendable member and translates relative to the first extendable member. The lift apparatus is fixedly coupled at an outer end of the second extendable member.

An end effector for use in the packaging industry has compression wedges that bookend subgroups of carrier assemblies on the end effector. The compression wedges are attached to the frame of the end effector via wedge blocks, which may be fixed to the frame or slidingly engaged with the frame.
