  • Publication number: 20240269836
    Abstract: A first transition section is set in a first base track and includes a connection point between the first base track and a second base track. A first machine learning model and a second machine learning model are set for the first base track and the second base track, respectively. When the actual track or the predicted track at the predetermined point is within the error range, the control device controls the automatic machine using the first machine learning model set for the first base track in the transition section. When the actual track or the predicted track at the predetermined point is outside the error range, the control device controls the automatic machine in the transition section by a control method different from that of the first machine learning model.

  • Publication number: 20240261980
    Abstract: The computer is connected to a robot including a hand which grips a workpiece, and a machining device including a gripping mechanism which grips the workpiece, acquires first operation information regarding an operation state of the robot and second operation information regarding an operation state of the machining device; and controls the robot to cause the robot to grip the workpiece and install the workpiece in the gripping mechanism In the control of the robot, the computer determines whether or not to start correction processing of correcting a position and an orientation of the workpiece with respect to the gripping mechanism based on the second operation information, executes the correction processing using the first operation information and the second operation information, and determines whether or not to end the correction processing based on the second operation information.

  • Publication number: 20240042607
    Abstract: An inspection route generation device generates an inspection route of an external appearance inspection device which performs external appearance inspection on an inspection target based on an image imaged by an imaging unit, and includes: a storage unit which stores inspection position information indicating a plurality of inspection positions at which the imaging unit images the inspection target, and inspection device configuration information indicating a configuration of the external appearance inspection device; and a route determination unit which calculates a route length between respective inspection positions, and a posture change amount of the imaging unit at a time when the imaging unit moves through the plurality of inspection positions, based on the inspection position information and the inspection device configuration information, and determines the inspection route based on the calculated route length and posture change amount.

  • Publication number: 20230113622
    Abstract: A robot that performs work including gripping an object and moving the object is controlled with high accuracy. A computer for controlling the robot that performs the work including gripping the object and moving the object stores trajectory information, acquires operating state information including a value indicating an operating state of the robot during the work and work state information including a value for grasping a state of the object gripped by the robot, generates estimated work state information including a value for grasping a future state of the object gripped by the robot based on the trajectory information, the operating state information, and the work state information, and generates control information for controlling the robot based on the trajectory information, the operating state information, the work state information, and the estimated work state information.

  • Publication number: 20220324099
    Abstract: Various gripped objects having different sizes, weights, centers of gravity, and the like are continuously and stably moved at a high speed. A control device includes: a state information generation unit that generates and updates state information on a robot and a gripped object; and a control information generation unit that generates, based on the state information and a base trajectory generated in advance on which the robot is configured to move the gripped object from a start point to an end point, control information for controlling the robot.
