  • Patent number: 11931895
    Abstract: A robot control system includes circuitry configured to: determine a necessity of assisting a robot to complete an automated work, based on environment information of the robot; select a remote operator from candidate remote operators based on stored operator data in response to determining that it is necessary to assist the robot to complete the automated work; transmit the environment information to the selected remote operator via a communication network; receive an operation instruction based on the environment information from the selected remote operator via the communication network; and control the robot to complete the automated work based on the operation instruction.
    Type: Grant

  • Publication number: 20230010302
    Abstract: A robot control system includes circuitry configured to: generate a command to a robot; receive a frame image in which a capture position changes according to a motion of the robot based on the command; extract a partial region from the frame image according to the command; superimpose a delay mark on the partial region to generate an operation image; and display the operation image on a display device, so as to represent a delay of the motion of the robot with respect to the command.

  • Publication number: 20220371203
    Abstract: A robot control system includes circuitry configured to: acquire an input command value indicating a manipulation of a robot by a subject user; acquire a current state of the robot and a target state associated with the manipulation of the robot; determine a state difference between the current state and the target state; acquire from a learned model, a degree of distribution associated with a motion of the robot, based on the state difference, wherein the learned model is generated based on a past robot manipulation; set a level of assistance to be given during the manipulation of the robot by the subject user, based on the degree of distribution acquired; and generate an output command value for operating the robot, based on the input command value and the level of assistance.

  • Publication number: 20140135984
    Abstract: A robot system includes a robot, a storage, an authenticator, a determinator, and an instructor. The robot shares a workspace with a worker. The storage stores authentication information of the worker. While the worker is approaching the workspace, the authenticator determines whether the worker is a registered worker based on the authentication information. When the worker is authenticated as a registered worker by the authenticator, the determinator determines a new operation area and a new operation speed of the robot in accordance with a type of work and a work experience of the worker. The type of work and the work experience are identified when the worker is authenticated as a registered worker by the authenticator. The instructor instructs the robot to operate based on the new operation area and the new operation speed of the robot determined by the determinator.
