| 20090043425 | ROBOT PROGRAM ADJUSTING SYSTEM - A robot program adjusting system ( | 02-12-2009 |
| 20110015786 | MANIPULATOR - A manipulator comprises a tube body including a bending portion, a bending wire for bending drive of the bending portion, a motor including a rotary shaft which rotates in accordance with a drive command signal, a reduction gear unit connected to the rotary shaft and configured by a plurality of gears meshing with each other, a detection unit which detects an operation state of the motor, a storage unit which stores load variation values periodically caused by the meshing of the plurality of gears constituting the reduction gear unit as correction information, a load calculation section which calculates a load exerted on the tube body as a bending load estimated value, and a notifying unit which notifies a calculation result of the load calculation section. | 01-20-2011 |
| 20150367518 | SYSTEM FOR CONTROLLING POSITION POSE OF ROBOT USING CONTROL OF CENTER OF MASS - A control system of a robot keeps an entire posture of a robot not fixed to the ground. The robot includes a body having a plurality of joints and motors mounted to a plurality of limbs and the joints, and the entire posture is maintained by controlling a center of mass (COM) of the robot. The limbs include a robot arm with an end-effector. When a target position of the end-effector (hereinafter, a “target end-effector position”) is input, a target position of the center of mass (hereinafter, a “target COM position”) is calculated using the target end-effector position. The motors mounted to the joints are operated so that the end-effector and the center of mass of the robot move according to the target end-effector position and the target COM position. The target COM position varies in proportion to the change of the target end-effector position. | 12-24-2015 |
| 20160052132 | ROBOT MOTION DATA PROCESSING SYSTEM USING MOTION DATA REDUCTION/RESTORATION COMPATIBLE TO HARDWARE LIMITS - A robot motion data processing system has a data extraction module for intermittently extracting restoration motion data from a successive input motion trajectory formed for controlling a motion of a robot, and a data restoration module for restoring an output motion trajectory approximate to the input motion trajectory by using restoration motion data extracted from the data extraction module. The output motion trajectory is restored to satisfy a condition that the robot operating according to the output motion trajectory does not exceed a hardware operation limit of the robot. | 02-25-2016 |
| 20160082591 | CONTROL DEVICE FOR MOBILE ROBOT - The present invention provides a control device for a mobile robot. While a mobile robot | 03-24-2016 |
| 20160121481 | METHOD AND APPARATUS TO MOVE AN ARTICULATED ARM - Method to move an articulated arm provided with a first end associated with a support and rotatable movement tower and with a second free end and including a plurality of segments pivoted with respect to each other and actuation members configured to make at least one of the segments rotate with respect to one other of the segments or to the support and rotatable movement tower, and where the method allows to manage and control the speed of movement of the articulated arm ( | 05-05-2016 |
| 20160121484 | CONTROL DEVICE WITH FUNCTION TO CHECK LOAD INFORMATION SETTINGS - A control device includes an estimated torque calculation unit, an actual torque calculation unit, a torque comparison unit, and a stop unit. The estimated torque calculation unit calculates an estimated torque for maintaining the posture of an automatic machine based on preset load information when the machine is in a resting state in which its posture is maintained by a torque applied by a servomotor. The actual torque calculation unit calculates an actual torque actually applied to maintain the posture. The torque comparison unit compares an error between the estimated and actual torques with a predetermined first threshold. The stop unit stops subsequent operations of the automatic machine when the error is greater than the first threshold. | 05-05-2016 |
| 20160129588 | Event-Based Redundancy Angle Configuration for Articulated-Arm Robots - The invention relates to a method and a system for controlling a robot, which has at least one redundant degree of freedom. The method according to the invention prevents the robot from colliding with its surrounding environment and/or from getting into an inconvenient position as a result of its redundancy, and does so without causing any disadvantageous displacement of the tool center point. | 05-12-2016 |
