  • Publication number: 20220152823
    Abstract: A machine learning model operation management system includes a model building server and an operation server. The model building server builds a trained machine learning model based on received training data. When the trained machine learning model stored in a robot controller operates for determining the operation of a robot, the operation server receives operation information generated by the robot controller. Data of the trained machine learning model built by the model building server is assigned with model identification information that uniquely identifies the trained machine learning model. The robot controller makes an external inquiry as to whether or not it has permission to use the trained machine learning model stored in itself, and if it has the permission to use, it makes the trained machine learning model available for use. The operation server stores the operation information in association with the model identification information.

  • Patent number: 11335578
    Abstract: A substrate transfer apparatus of the present invention includes: a robot including a hand configured to hold a substrate, and an arm configured to move the hand; a robot control device configured to set a moving path for the hand and control the arm such that the hand moves on the moving path toward a target position; and a camera disposed so as to be able to capture an image of the substrate held by the hand located at a predetermined confirmation position. The robot control device sets the moving path so as to pass through the confirmation position, obtains an image captured by the camera when the hand is located at the confirmation position, calculates a distance between a predetermined environment and the substrate which are taken in the image, and calculates a positional deviation amount from a reference position of the substrate on the basis of the distance.
