Patent number: 9156164Abstract: In a method for adjusting parameters of impedance control, an overshoot amount allowable value is set as an allowable maximum value of an overshoot amount of a time response of a force feedback from a force sensor provided for an end effector of a robot manipulator, and a setting time allowable value is set as an allowable maximum value of a setting time of the time response of the force feedback. A viscosity parameter with which the setting time is shortest is calculated while fixing the inertia parameter. An overshoot amount adjustment value and a setting time adjustment value which are obtained from a result of the calculating of the viscosity parameter are compared with the overshoot amount allowable value and the setting time allowable value, respectively, to determine whether a repeating process is finished or continued.Type: GrantFiled: November 21, 2013Date of Patent: October 13, 2015Assignee: KABUSHIKI KAISHA YASKAWA DENKIInventors: Shingo Ando, Ryoichi Nagai, Yasuyuki Inoue

Patent number: 8867873Abstract: An optical wavelength multi/demultiplexing circuit is provided in which temperature dependence at a transmission center wavelength remained in an athermalized AWG is compensated. An AWG according to an embodiment of the present invention is compensated for the main temperature dependence at the transmission center wavelength. The AWG comprises an optical splitter, a first and second arm waveguides, an optical mode combining coupler and a multimode waveguide between an input/output waveguide and a slab waveguide. The optical mode combining coupler couples fundamental mode light from the first arm waveguide as fundamental mode and the fundamental mode light from the second arm waveguide as first mode. The multimode waveguide is capable of propagating the fundamental and first mode light. This AWG is configured such that the temperature dependence remained in the arrayed waveguide grating is compensated by changing the optical path length difference between the first and second arm waveguides with temperature.Type: GrantFiled: June 30, 2009Date of Patent: October 21, 2014Assignee: Nippon Telegraph and Telephone CorporationInventors: Shin Kamei, Yasuyuki Inoue, Mikitaka Itoh

Patent number: 8798790Abstract: An apparatus for detecting a contact position where a robot makes contact with an object includes a probe, a probe-position calculating unit, a contact detecting unit, and a contact-position calculating unit. The probe is attached to the robot and is configured to make a displacement in a direction of making contact with the object in an elastic manner. The probe-position calculating unit calculates a position of the probe of the robot in operation. The contact detecting unit detects a contact state of the probe with the object. When the contact state of the probe is detected, the contact-position calculating unit derives the contact position based on a calculated position of the probe.Type: GrantFiled: March 9, 2011Date of Patent: August 5, 2014Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Yosuke Kamiya, Yasuyuki Inoue, Hideo Nagata
