  • Publication number: 20230264342
    Abstract: A control system includes a master device, a slave device, and a control device that controls the master device and the slave device. In the control device, a response value acquisition unit acquires data of physical quantities representing action of the movable portion of the master device, and data of physical quantities representing action of the movable portion of the slave device. A command value calculation unit hypothesizes a virtual object that includes the master device and the slave device, and calculates a command value for causing the master device and the slave device to follow behavior expressed in the virtual object by input to the master device and the slave device, on the basis of the data of physical quantities acquired by the response value acquisition unit.

  • Publication number: 20220134542
    Abstract: A position/force controller performs a first conversion for distributing control energy to at least one of velocity or position energy and force energy, in accordance with a function to be realized, based on velocity (or position) and force information, which correspond to information relating to a position based on an operation of an actuator, and information serving as reference of control. The position/force controller calculates at least one of a velocity or position control amount and a force control amount based on at least one of the energies obtained through the distribution. The position/force controller integrates the calculated control amounts, performs a second conversion, and determines input to the actuator. The position/force controller performs a process, corresponding to increasing or decreasing performed on at least one of the velocity or position energy and the force energy together or independently, with satisfaction of a condition set for the control energy.
