Patent number: 8700213Abstract: A compact, lightweight manipulation system that excels in operability and has a force feedback capability is provided. When automatic operation of a slave manipulator 105 that follows manual operation of a master manipulator 101 is bilaterally controlled by means of communication, the force acting on the slave manipulator is fed back to the master manipulator by operating the master manipulator primarily under electrically-driven speed control and the slave manipulator primarily under pneumatically-driven force control. Therefore, in the master manipulator, it is not necessary to compensate for the dynamics and the self-weight of the master manipulator in the motion range of a user, allowing highly accurate, broadband positional control, which is specific to an electrically-driven system, and in the slave manipulator, nonlinearity characteristics specific to a pneumatically-driven system presents passive softness, provides a high mass-to-output ratio, and produces a large force.Type: GrantFiled: February 29, 2008Date of Patent: April 15, 2014Assignee: Tokyo Institute of TechnologyInventors: Kenji Kawashima, Kotaro Tadano

Patent number: 8689660Abstract: A steering device provides a driver operation feeling that lets the driver definitely feel that a movable tilt lock gear and a fixed tilt lock gear are securely engaged. Gear noise in tilt adjustment when the movable tilt lock gear and the fixed tilt lock gear are engaged halfway is prevented. As the control force of an operating lever is rapidly decreased when a fitting protrusion is fitted to a stepped part, a click and click stop feeling occur and a definite operation feeling that the clamping is securely performed is acquired. As the fitting protrusion is integrated with the operating lever and a sliding surface configured by a groove, an inclined face and the stepped part are also formed as an outside face of the fixed tilt lock gear, the number of parts and man-hours for assembly can be reduced.Type: GrantFiled: August 29, 2011Date of Patent: April 8, 2014Assignee: NSK Ltd.Inventor: Shinji Okada
