Patent number: 11751744Abstract: A moving robot and a controlling method thereof are disclosed. The moving robot includes a dust sensor that detects dust in air suctioned during cleaning, and a controller that performs control so that the robot performs cleaning while traveling over a traveling area distinguished into a plurality of regions. The controller stores, in the data unit, dust information detected by the dust sensor and a number of times of cleaning in each region. The controller also sets a cleaning region and a non-cleaning region based on cleaning data, which is calculated based on the dust information and the number of times of cleaning. This helps prevent cleaning from being repeated unnecessarily and allows for cleaning depending on the number of times of cleaning, despite a small amount of dust. Accordingly, an entire indoor area may be maintained in a constant clean state and cleaning efficiency may be enhanced.Type: GrantFiled: September 21, 2018Date of Patent: September 12, 2023Assignee: LG ELECTRONICS INC.Inventor: Wonchul Jo

Patent number: 11318611Abstract: A method for controlling a robot to perform a complex assembly task such as insertion of a component with multiple pins or pegs into a structure with multiple holes. The method uses an impedance controller including multiple reference centers with one set of gain factors. Only translational gain factors are used—one for a spring force and one for a damping force—and no rotational gains. The method computes spring-damping forces from reference center positions and velocities using the gain values, and measures contact force and torque with a sensor coupled between the robot arm and the component being manipulated. The computed spring-damping forces are then summed with the measured contact force and torque, to provide a resultant force and torque at the center of gravity of the component. A new component pose is then computed based on the resultant force and torque using impedance controller calculations.Type: GrantFiled: April 14, 2020Date of Patent: May 3, 2022Assignee: FANUC CORPORATIONInventors: Yu Zhao, Tetsuaki Kato

Patent number: 8301305Abstract: A moving device is provided. A first receiving device receives an emitted light from a base station and obtains a direction from a start position, which the moving device is in to the base station according to the emitted light to serve as a target direction. A driving device drives the moving device to move in the target direction from the start position. When the moving device meets a first obstacle which is disposed along the target direction and in the target area, a second receiving device obtains a distance between the moving device and the base station according to the received emitted light to serve as a middle distance. When a determination device determines that the middle distance is not equal to a predetermined distance, the driving device drives the moving device to detour around the first obstacle and move in the target direction continuously.Type: GrantFiled: March 22, 2010Date of Patent: October 30, 2012Assignee: MSI Computer (Shenzhen) Co., Ltd.Inventors: Chuan-Ching Tsao, Yung-Shen Lee, Shih-Chieh Chou, Hong Lun Liu

Patent number: 8271132Abstract: Systems, methods, and user interfaces are used for controlling a robot. An environment map and a robot designator are presented to a user. The user may place, move, and modify task designators on the environment map. The task designators indicate a position in the environment map and indicate a task for the robot to achieve. A control intermediary links task designators with robot instructions issued to the robot. The control intermediary analyzes a relative position between the task designators and the robot. The control intermediary uses the analysis to determine a task-oriented autonomy level for the robot and communicates target achievement information to the robot. The target achievement information may include instructions for directly guiding the robot if the task-oriented autonomy level indicates low robot initiative and may include instructions for directing the robot to determine a robot plan for achieving the task if the task-oriented autonomy level indicates high robot initiative.Type: GrantFiled: March 13, 2008Date of Patent: September 18, 2012Assignee: Battelle Energy Alliance, LLCInventors: Curtis Nielsen, David Bruemmer, Douglas Few, Miles Walton

Patent number: 8260443Abstract: A method for the optimized movement co-ordination of measuring machines or machine tools having redundant axles having at translatory action, wherein the longer partial axles in each case permit a relatively slowly accelerated partial movement over a relatively large measuring or processing space and the shorter partial axles in each case essentially carry out the movement components of a total movement at a substantially altogether constant measuring or processing speed, which require an acceleration beyond a maximum set or stipulated for the respective longer partial axles, wherein, when approaching positions that in an undivided movement would otherwise not be attainable, the base axles correspondingly decelerate and can even come to a complete standstill, wherein by simultaneous displacement of the neutral starting point of the additional axles, the respective movement component of the base axles missing from the total movement is compensated.Type: GrantFiled: December 21, 2009Date of Patent: September 4, 2012Assignee: TRUMPF Werkzeugmaschinen GmbH + Co.

Patent number: 8180488Abstract: A robot system includes a robot and a robot controller including a drive unit, a memory that stores an arm-occupied region and a movement-forbidden region, a target position calculation unit that outputs a target position of a tool or a workpiece, a movement-forbidden region entry monitoring unit that checks whether the arm-occupied region based on the target position enters the movement-forbidden region and outputs a stop request if it is checked that the arm-occupied region enters the movement-forbidden region, and a predicted-coasting-position calculating unit that calculates a predicted coasting position of each axis and a coasting position of the tool or the workpiece in the case that the robot is urgently stopped. The movement-forbidden region entry monitoring unit checks whether the arm-occupied region at the coasting position enters the movement-forbidden region and outputs another stop request if it is checked that the arm-occupied region enters the movement-forbidden region.Type: GrantFiled: June 3, 2010Date of Patent: May 15, 2012Assignee: Kabushiki Kaisha Yaskawa DenkiInventors: Hirokazu Kariyazaki, Shinichi Maehara, Minoru Yamamoto, Michiharu Tanaka

Patent number: 8145354Abstract: Systems and methods are presented that enable a legged robot to maintain its balance when subjected to an unexpected force. In the reflex phase, the robot withstands the immediate effect of the force by yielding to it. In one embodiment, during the reflex phase, the control system determines an instruction that will cause the robot to perform a movement that generates a negative rate of change of the robot's angular momentum at its centroid in a magnitude large enough to compensate for the destabilizing effect of the force. In the recovery phase, the robot recovers its posture after having moved during the reflex phase. In one embodiment, the robot returns to a statically stable upright posture that maximizes the robot's potential energy. In one embodiment, during the recovery phase, the control system determines an instruction that will cause the robot to perform a movement that increases its potential energy.Type: GrantFiled: October 14, 2010Date of Patent: March 27, 2012Assignee: Honda Motor Co., Ltd.Inventors: Ambarish Goswami, Muhammad E.

Patent number: 8050780Abstract: A servo-controlled system is disclosed for providing simulated feel equivalent to that of traditional mechanical hand controllers. Processed position and force sensor signals are used in a feedback loop that controls the motor mechanically connected to the stick. The feedback loop comprises a low-level motor feedback loop, and high-level force feel loop. The latter comprises static and dynamic performance components. The system allows variable and additional force cues to be specified externally to the system and felt by the operator, and/or external signal to backdrive the stick to follow a specified motion. The control framework permits the electronic coupling of the motion and applied forces by pilots in a dual arrangement while retaining the above-mentioned features. It simulates cross-coupling mechanical compliance due to force fight between pilots, detents and asymmetric force feel gradients. Parameters associated with loops and performance components can be specified independently.Type: GrantFiled: November 6, 2002Date of Patent: November 1, 2011Inventors: Claude Tessier, Jonathan Martineau
