  • Publication number: 20210220990
    Abstract: A robot system (1) includes the robot (10), a motion sensor (11), a surrounding environment sensor (12, 13), an operation apparatus (21), a learning control section (41), and a relay apparatus (30). The robot (10) performs work based on an operation command. The operation apparatus (21) detects and outputs an operator-operating force applied by the operator. The learning control section (41) outputs a calculation operating force. The relay apparatus (30) outputs the operation command based on the operator-operating force and the calculation operating force. The learning control section (41) estimates and outputs the calculation operating force by using a model constructed by performing the machine learning of the operator-operating force, the surrounding environment data, the operation data, and the operation command based on the operation data and the surrounding environment data outputted by the sensors (11 to 13), and the operation command outputted by the relay apparatus (30).

  • Publication number: 20210197369
    Abstract: A robot system includes a robot, state detection sensors to, a timekeeping unit, a learning control unit, a determination unit, an operation device, and an input unit, and an additional learning unit. The determination unit determines whether or not the work of the robot can be continued under the control of the learning control unit based on the state values detected by the state detection sensors to and outputs determination result. The additional learning unit performs additional learning of the determination result indicating that the work of the robot cannot be continued, the operator operation force, work state output by the operation device and the input unit, and timer signal output by the timekeeping unit.

  • Publication number: 20200366815
    Abstract: An environment acquisition system includes a housing, a visual sensor, and a data processor. The visual sensor is accommodated in the housing and is capable of acquiring environmental information about environment of outside of the housing repeatedly. The data processor performs an estimation process of a position and a posture of the visual sensor and a generating process of an external environment three-dimensional data based on the environmental information acquired by the visual sensor or information obtained from the environmental information. In a state where a posture of the housing is not controlled and the housing is not in contact with ground and is not mechanically restrained from outside, the visual sensor can acquire the environmental information.

  • Publication number: 20200353620
    Abstract: A robot system includes a robot, an image acquisition part, an image prediction part, and an operation controller. The image acquisition part acquires a current image captured by a robot camera arranged to move with the end effector. The image prediction part predicts a next image to be captured by the robot camera based on a teaching image model and the current image. The teaching image model is constructed by a machine learning of teaching image which is predicted to capture by the robot camera while the movable part performs an adjustment operation. The operation controller calculates the command value for operating the movable part so that the image captured by the robot camera approaches the next image, and controls the movable part based on the command value.

  • Publication number: 20200139539
    Abstract: The automatic operation system includes a plurality of learned imitation models and a model selecting unit. The learned imitation models are constructed by machine learning of operation history data, the operation history data being classified into several groups by an automatic classification system algorithm, the operation history data of each group being learned by the imitation model corresponding to the group. The operation history data include data indicating a surrounding environment and data indicating an operation of an operator in the surrounding environment. The model selecting unit selects one imitation model from several imitation models based on a result of classifying data indicating a given surrounding environment by the automatic classification algorithm of the classification system.

  • Patent number: 8388035
    Abstract: A robot hand is configured such that a plurality of finger mechanisms are disposed on base and operate so as to cause fingertip portions thereof to get close to each other and separate from each other. At least one of the plurality of finger mechanisms is constituted by a Chebychev link mechanism including a driving link configured to be rotated about a base end portion thereof supported by the base, a driven link having a base end portion coupled to the base so as to be swingable, and an intermediate link having a base end portion coupled to a tip end portion of the driving link so as to be swingable and a center portion coupled to a tip end portion of the driven link so as to be swingable. The fingertip portions are respectively provided at tip end portions of the intermediate links.
