  • Publication number: 20230373078
    Abstract: A controller of a robot system performs first control of controlling a robot arm in accordance with an operation with an operator to thereby cause an end effector to apply a treatment to an object and of recording trajectory data and second control of controlling the robot arm based on the trajectory data recorded in the first control to thereby move the end effector such that the end effector reproduces a moving trajectory and applies a treatment to the object. In the second control, in controlling the robot arm based on the trajectory data, the controller controls a pressing force of the end effector against the object.

  • Publication number: 20220401169
    Abstract: A master-slave system includes a master unit, a slave unit, and a control device. The control device includes first circuitry that determines a first relationship that is a relationship between a slave coordinate system and an object coordinate system, second circuitry that determines a second relationship that is a relationship between a master coordinate system and the object coordinate system, and third circuitry that outputs an operational command for causing the slave unit to operate according to operational information of the master unit, the first relationship, and the second relationship. When the object coordinate system is moved, the first circuitry newly determines the first relationship after the movement based on the moved object coordinate system and the slave coordinate system, and the second-circuitry determines the second relationship after the movement, as a relationship similar to the second relationship before the movement.

  • Publication number: 20220388160
    Abstract: A control device includes: first circuitry that generates a command to cause a robot to autonomously grind a grinding target portion; second circuitry that generates a command to cause the robot to grind a grinding target portion according to manipulation information from an operation device; third circuitry that controls operation of the robot according to the command; storage that stores image data of a grinding target portion and operation data of the robot corresponding to the command; and forth circuitry that performs machine learning by using image data of a grinding target portion and the operation data for the grinding target portion, receives the image data as input data, and outputs an operation correspondence command corresponding to the operation data as output data. The first circuitry generates the command, based on the operation correspondence command.

  • Patent number: 11292073
    Abstract: A welding torch includes a gas lens of a lattice structure that straightens a shielding gas. The welding torch includes a non-consumable electrode, an electrode holder into which the non-consumable electrode is inserted, and a torch body including a sleeve that holds the electrode holder, a flow path forming portion that forms a shielding gas flow path around the sleeve, and a nozzle that forms a shielding gas guiding space around a distal end of the non-consumable electrode, the distal end extending from the electrode holder, in which the gas lens is provided so as to separate the shielding gas flow path from the shielding gas guiding space.

  • Patent number: 11292070
    Abstract: A welding torch includes a torch body including a flow path forming portion that forms a shielding gas flow path into which an inert gas flows and an outer gas flow path communicating with the shielding gas flow path, a first gas lens that straightens the inert gas in the shielding gas flow path and blows the inert gas out as a shielding gas, and a second gas lens that straightens the inert gas in the outer gas flow path and blows the inert gas out as an outer gas. Provided is an all-position welding device that performs butt welding of tubes, and includes the welding torch and a rotation mechanism for rotating the welding torch around the tube.
