  • Publication number: 20250236018
    Abstract: A method of controlling a robot manipulator for operating in a shared workspace with human(s) is provided. The method includes: determining a safety control set with respect to a safety condition between selected part(s) of the robot manipulator and selected part(s) of the human(s) using a safety control function: determining a hard constraint control set with respect to hard constraint(s) in trajectory tracking in DOF(s) of a component of the robot manipulator for a task using a hard constraint function: determining a soft constraint control set with respect to soft constraint(s) in trajectory tracking in DOF(s) of the component for the task using a soft constraint function: and performing control input optimization based on the safety control set. the hard constraint control set and the soft constraint control set to determine a control input for controlling the robot manipulator.

  • Publication number: 20250196369
    Abstract: A material handling system includes: a frame defining a first axis; a plurality of suction units coupled to the frame and distributed in rotational symmetry about the first axis; and at least one stopper. The plurality of suction units collectively defines a distal plane normal to the first axis, with each of the plurality of suction units being operable to provide a suction force in a suction direction parallel to the first axis. The at least one stopper is fixedly coupled to the frame and extends beyond the distal plane to provide one or more abutment ends disposed stationary relative to the frame. The one or more abutment ends define a transverse offset axis extending through all of the one or more abutment ends. The transverse offset axis is a straight line spaced apart from the first axis and parallel to the distal plane.

  • Patent number: 10888977
    Abstract: The present disclosure relates to a suction device including a shell with a chamber, the chamber including an opening. A fan is disposed in the chamber, and a power component for driving the fan to rotate is disposed on the shell. An external fluid source holding an additional fluid is connected to the chamber. The additional fluid of the external fluid source flows into the chamber to occupy a volume in the chamber and at least partially forces a first fluid originally present in the chamber out of the chamber. The fan drives fluids in the chamber to rotate so that a stepped negative pressure is generated in the chamber, with a magnitude of the negative pressure decreasing as a distance to a periphery of the chamber decreases. Thereby, a pressure difference between an inside and an outside of the shell is decreased, decreasing vacuum leakage of the suction device.
