  • Patent number: 11110592
    Abstract: A remote control robot system includes a slave arm configured to perform a given work, a master arm having a motor configured to drive a joint, and configured to receive from an operator an operation to manipulate the slave arm, an instruction generating module configured to generate an instruction to apply to the master arm an imaginary external force in a given direction that is independent from a force received by the slave arm from the exterior, and a motor controller configured to supply, to the motor, drive current corresponding to the instruction sent from the instruction generating module.

  • 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: 20200206893
    Abstract: A robot system includes a slave unit including a slave-side force detector configured to detect a direction and a magnitude of a reaction force acting on a workpiece held by a work end of a slave arm, a master unit including a master-side force detector configured to detect a direction and a magnitude of an operating force applied by an operator to an operation end of a master arm, and a system controller configured to generate a slave operational command and a master operational command based on the operating force and the reaction force. The system controller includes a regulator configured to correct a moving direction of the work end so that the movement of the work end in a pressing direction of an object is regulated when the reaction force exceeds an acceptable value set beforehand.

  • Publication number: 20200198120
    Abstract: A robot system includes a manipulating force detector configured to detect a manipulating force given to an operation end by an operator, a reaction-force detector configured to detect a reaction force given to a work end or a workpiece held by the work end, a system controller configured to generate an operating command of a master arm and generate an operating command of a slave arm based on the manipulating force and the reaction force, a master-side control part configured to control the master arm, and a slave-side control part configured to control the slave arm. The system controller has an exaggerated expresser configured to exaggeratedly present an operating feel to the operator who operates the operation end in a reaction-force sudden change state that is a state in which the reaction force changes rapidly with time.
