  • Patent number: 12163562
    Abstract: A joint locking mechanism comprising a latch assembly and a gear movable relative to the latch assembly and comprising gear teeth. The latch assembly comprises an actuator moveable between a withdrawn position and a deployed position; first and second latches, each comprising an engagement element adapted to interlock with the gear teeth, each being moveable between an unlocked position and a locked position; a pivotable coupling comprising a first end coupled to the first latch, a second end coupled to the second latch, and a pivot positioned between the first and second ends which is rotatably coupled to the actuator. When the actuator is in the withdrawn position both the first and second latches are in the unlocked position. Movement of the actuator from the withdrawn position to the deployed position causes one, but not both, of the first and second latches to move to the locked position.

  • Publication number: 20240383144
    Abstract: An apparatus including computer program code configured to cause the apparatus to: receive a command defining a desired pose of an end effector of a robotic instrument; determine, based on the command, joint parameters for each joint of the robotic instrument using an inverse kinematics algorithm to enable the end effector to mimic the desired pose as closely as possible, wherein the algorithm is configured to reiteratively calculate a pose of the end effector and identify the calculated pose with the smallest tracking error as a global solution if the tracking error is smaller than that associated with a current pose of the end effector, otherwise identify the current pose as the global solution; and wherein the apparatus is configured to generate a motor command to reconfigure the joints according to the global solution if the calculated pose with the smallest tracking error is identified as the global solution.

  • Patent number: 11072854
    Abstract: A substrate fixing carrier includes a supporting frame and a cooling plate. The supporting frame defines a hollow region and a supporting portion at an inner wall of the supporting frame. The cooling plate and the supporting frame are movable towards each other until the cooling plate is in the hollow region with edges of the cooling plate aligning with the supporting portion. When a rectangular to-be-evaporated substrate is placed in the hollow region with edges of the rectangular to-be-evaporated substrate between the supporting portion and the cooling plate, a distance between each edge of the cooling plate corresponding to each long side of the to-be-evaporated substrate and the supporting portion is greater than or equal to a thickness of the to-be-evaporated substrate, and a distance between each edge of the cooling plate corresponding to each short side of the to-be-evaporated substrate and the supporting portion is less than the thickness of the to-be-evaporated substrate.
