Abstract: The present subject matter is directed to a work vehicle, such as a construction vehicle, including a first arm, a second arm pivotably coupled to the first arm, and a hydraulic fitting assembly coupled between the first arm and the second arm at a pivot joint and configured to lubricate the pivot joint. The hydraulic fitting assembly includes a first and second housing each defining a cavity configured to receive a hydraulic fluid therein. The cavity of each of the first and second housing are aligned. The first and second housings are each configured to rotate relative to one another when either the first arm or the second arm is pivoted. The lubrication applicator assembly defines a channel configured to receive a lubricant.

Abstract: Work vehicles, such as construction vehicles, include an attachment tool to transport material. The attachment tool is coupled to a lift arm assembly of the construction vehicle via a coupling assembly. The coupling assembly is designed to be coupled to any one of a variety of attachment tools. However, coupling assemblies commonly utilize coupling pins to couple the attachment tool to the lift arm assembly. The coupling pins are onerous to insert/remove and prone to rusting. Furthermore, the coupling assemblies often have too much lateral tolerance. As such, the attachment tools are prone to lateral movement relative to the lift arm during operation. Therefore, an attachment tool coupling assembly for a construction vehicle is needed to easily couple and release the attachment tool from the lift arm assembly and prevent lateral movement of the attachment tool relative to the lift arm assembly.

Abstract: A powered user interface for a robotic surgical system operates in accordance with a mode of operation in which the actuators are operated to permit motion of the handle in pitch and yaw motion constrained with respect to a virtual fulcrum in a work space of the user interface, and insertion motion is constrained along an axis passing through the virtual fulcrum. In a virtual fulcrum setting mode, a user is prompted to give input to the system selecting a desired point in space for the virtual fulcrum. The selected point in space is then set as the virtual fulcrum.

Abstract: A surgical instrument for use with a robotic manipulator includes an end effector assembly having one or two end effector members, each having a distal treatment end, a proximal end, and a tendon pass-through. Each end effector member is sandwiched between a corresponding pair of pulley members that, when assembled define an annular tendon pathway that is between the pulley members and that is aligned with the pass-through. For each end effector member, a tendon having a distal loop portion ends through the tendon pass-through, with its legs passing proximally from the pass-through, extending in opposite directions around the tendon pathway and proximally through the instrument's shaft.
