Patent number: 11420330Abstract: A robot control device according to an aspect of the invention is a robot control device that controls a robot on the basis of a simulation result of a simulation device that performs a simulation of operation of a virtual robot on a virtual space. In the simulation, a first region and a second region located on an inside of the first region can be set on the virtual space. In the case where the virtual robot operates, when a specific portion of the virtual robot intrudes into the first region, operating speed of the virtual robot is limited. When the specific portion of the virtual robot intrudes into the second region, the operation of the virtual robot stops or the virtual robot retracts from the second region.Type: GrantFiled: June 24, 2019Date of Patent: August 23, 2022Inventors: Masanobu Nishitani, Tsutomu Hagihara, Norio Yokoshima, Kazuhiro Masuda

Patent number: 10173325Abstract: A robot includes a force detector, and a drive part that changes a position relationship between a marker and an imaging part. In the case with calibration processing of specifying a coordinate relationship as a correspondence relationship between a reference coordinate system with reference to a position of the marker and a robot coordinate system as reference of control of the drive part based on images of the marker captured by the imaging part in a plurality of the position relationships, the drive part is controlled to have anisotropy based on the coordinate relationship and a detection value of the force detector.Type: GrantFiled: March 10, 2016Date of Patent: January 8, 2019Assignee: Seiko Epson CorporationInventors: Masaki Motoyoshi, Norio Yokoshima

Patent number: 5239248Abstract: A servo control system effects control of a control object directly from an arbitrary stop position to a target position smoothly and safely. The servo control system has a detector for detecting an absolute position of the control object, and an observer for observing state values such as the position and/or velocity of the control object and a disturbance applied to the control object so as to servo-control the control object. The servo control system calculates initial state values of the observer determined according to the stop or rest position of the control object at the start of the operation so that the initial values are utilized for calculation of the state values by the observer. The observer calculates the state values and estimated values according to an algorithm at one sample preceding period, thereby enabling computation suitable to digital processing by the sampling mode operation.Type: GrantFiled: January 17, 1992Date of Patent: August 24, 1993Assignee: Seiko Instruments Inc.Inventors: Akira Shimada, Norio Yokoshima

Patent number: 5102289Abstract: A damper device for a precision assembling robot is capable of dampening the residual vibrations of the robot arm resulting from a lack of rigidity of the arm. The damper device is fixed to the tip of the robot arm to absorb the vibration energy of the swinging robot arm. The damper device includes a cylindrical weight member and a columnar rubber member. The damper device further includes a metallic rod inserted in the columnar rubber member. The length and position of the inserted metallic rod controls the dampening factor of the damper device. Therefore, the precision assembling robot with the damper device is capable of preventing a failure of assembly due to positioning errors resulting from residual vibrations, or nonconformities due to the impact of the robot arm against an object.Type: GrantFiled: May 15, 1989Date of Patent: April 7, 1992Assignee: Seiko Instruments Inc.Inventors: Norio Yokoshima, Masahide Nagai, Akira Shimada
