  • Patent number: 12103184
    Abstract: 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.

  • Publication number: 20230107488
    Abstract: A stack containment fixture is disclosed. The stack containment fixture includes an insertion zone structure including an insertion zone structure and a kitting area structure. The insertion zone structure includes a pair of substantially vertically oriented deflecting arms. each having one or more funnels configured to guide a stack into a position between the deflecting arms as the stack is lowered into the insertion zone structure from above. The kitting area structure is configured to support the vehicle or the stack during kitting operations for items being placed in the vehicle or stack or for items being picked from the vehicle or stack.

  • Publication number: 20230092900
    Abstract: The present application discloses a robotic control system, and a method and a computer system for controlling a robot. The robotic control system includes a memory and one or more processors coupled to the memory. The memory is configured to store configured to store a model of a robot having a plurality of axes of control including at least a linear axis and one or more rotational axes. The one or more processors are configured to use the model to control the robot to perform a task, including by sending to the robot a set of control signals to cause the robot to move with respect to two or more of said axes of control including at least the linear axis.
