  • Patent number: 11913849
    Abstract: A multi-degree of freedom (DOF) force and torque sensor is provided. The multi-DOF force and torque sensor includes a first rigid plate, a second rigid plate, multiple elastic elements connected between the first and second rigid plates, and multiple signal pairs connected between the first and second rigid plates. The signal pairs are used for detecting relative displacements of the first and second rigid plates in multiple directions.

  • Publication number: 20240009848
    Abstract: The present disclosure relates to a kinematics calibration method for a robot with multiple degrees of freedom. The robot includes a base, an end effector, and a plurality of links connected by joints. The method includes locking part of the multiple degrees of freedom by limiting the base and the end effector impose a limitation of degree of freedom; moving the robot to perform a first movement and accordingly obtaining a first set of data associated with joint angles and a first actual motion of the end effector; calculating a first theoretical motion of the end effector based on the first set of data and initial kinematics parameters; and updating the initial kinematics parameters of the robot to obtain a first set of updated kinematics parameters based on the first theoretical motion and the first actual motion.

  • Patent number: 11260538
    Abstract: A teaching system for a robot is provided, including a motion bar for controlling the robot and a robot system utilizing the teaching system. In one embodiment, the teaching system is provided including a first controller configured to provide motion-related control functions for controlling motion of the robot. The teaching system may also include a second controller configured to provide control functions other than the motion-related control functions for programming one or more actions of the robot.

  • Patent number: 11167433
    Abstract: The present disclosure describes a sealing apparatus for a robot and an articulated robot utilizing the sealing apparatus. In one embodiment, the sealing apparatus includes a first enclosure and a second enclosure. The second enclosure may be rotatably connected to the first enclosure such that the first enclosure and the second enclosure cooperatively define a gap between the first enclosure and the second enclosure. The sealing apparatus may further include a seal disposed in the gap such that the seal and the second enclosure cooperatively define a chamber. The sealing apparatus also includes an elastomer disposed in the chamber. The elastomer may be compressed by the seal and the second enclosure to generate an elastic force that presses the seal against the first enclosure.

  • Publication number: 20200357078
    Abstract: Provided is a method, apparatus, system and electronic device for credit tax refundment. The method for credit tax refundment comprises receiving a request for credit tax refundment and a refund amount; parsing the request for credit tax refundment to obtain identity information of a user applying for refundment; determining whether or not a user corresponding to the request is eligible for credit tax refundment based on the identity information of the user; obtaining an associated account based on the identity information of the user and remitting a tax refund of an equivalent amount into the associated account, in the case that the user corresponding to the request is eligible for credit tax refundment.

  • Patent number: 10245767
    Abstract: A bracket assembly suitable for use with an electronic device is described. The bracket assembly may include a bracket body having a channel. The bracket assembly may further include a membrane embedded in the bracket body and designed to allow air, but not liquid (such as water), to pass through the membrane. The membrane may be at least partially surrounded by a membrane support molded to the membrane. The membrane and the membrane support may be disposed in a molding tool to receive a material used to mold the bracket body over the membrane and the membrane support. During the molding operation, the membrane support may act as a buffer to shield the membrane from temperature and pressure increases associated with the molding operation of the bracket body. The bracket assembly may improve the ability of the electronic device to prevent liquid ingress.
