Publication number: 20230264342Abstract: 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.Type: ApplicationFiled: June 25, 2021Publication date: August 24, 2023Applicant: KEIO UNIVERSITYInventor: Takahiro NOZAKI
