METHOD FOR CHECKING A SAFETY AREA OF A ROBOT
A method for checking a safety area of a robot with an augmented reality human machine interface (AR-HMI) that comprises a display and a video camera. The method includes: acquiring, at the AR-HMI, a robot type of the robot, displaying, in the display of the AR-HMI, a virtual robot image of at least part of a robot of the robot type in a manner such that the virtual robot image overlays an actual robot image of the robot of the robot type in the video camera of the AR-HMI, aligning a position of the virtual robot image with a position of the actual robot image by moving the AR-HMI in three-dimensional space, confirming the alignment of the position between the virtual robot image and the actual robot image, and displaying a virtual first safety cell area around the virtual robot image in the confirmed position as an overlay of the actual robot image in the display of the AR-HMI.
ABNORMALITY DETECTION DEVICE WHICH DETECTS ABNORMALITIES IN POWER TRANSMISSION MECHANISM FOR TRANSMITTING ROTATIONAL FORCE OUTPUTTED BY MOTOR
This abnormality detection device is provided with a first encoder for detecting the rotation angle of an input shaft of a decelerator, and a second encoder for detecting the rotation angle of an output shaft of the decelerator. An operation control unit controls a servo motor such that the position acquired from the output of the second encoder corresponds to a position determined by an operation program. A detection unit calculates the angle difference, which is the difference between the rotation angle acquired from output of the first encoder and the rotation angle acquired from output of the second encoder. The detection unit determines whether or not the decelerator is abnormal on the basis of the angle difference.
Life evaluating device and robot system
Provided is a life evaluating device that evaluates the life of a lubricant in a machine including a motor and a transmission mechanism that is lubricated by the lubricant and transmits power of the motor to a movable unit. The life evaluating device includes a motor-heat-value calculating unit that calculates a motor heat value on the basis of a current value of the motor, a frictional-heat-value calculating unit that calculates a frictional heat value in the transmission mechanism on the basis of rotating speed of the motor and a coefficient of friction of the transmission mechanism, a lubricant-temperature estimating unit that estimates temperature of the lubricant on the basis of the calculated frictional heat value and the calculated motor heat value, and a life estimating unit that estimates the life of the lubricant on the basis of the estimated temperature of the lubricant and information concerning impurities in the lubricant.
Exoskeleton continuous-use fit evaluation system and method
A method of performing a fit test on an actuator unit coupled to a user. The method includes determining a first configuration of the actuator unit generated in response to actuating the actuator unit while the user is performing one or more movements for the fit test; determining a change from the first configuration of the actuator unit while the user is performing the one or more movements for the fit test; determining that the change from the first configuration corresponds to an improper fit of the actuator unit coupled the user; and generating an improper fit indication that indicates improper fit of at least leg actuator units coupled the user.
Shear pin for robot calibration
A shear pin for calibrating an industrial robot, the shear pin including an elongated body including a weakening defining a break location in case of overload. The shear pin is configured to be mounted to a calibration pin holder on the robot. A maximum force that the calibration pin can exert on the robot during calibration can be easily limited by dimensioning the weakening appropriately.
Vibration analyzer and vibration analysis method
A vibration analyzer includes a sensor that measures a vibration of an end effector supported by a distal end of a robot, a storage unit that stores a vibration calculation model of the robot, and a control unit configured to perform separation processing for separating a vibration to be reduced that is measured by the sensor into vibration data of the robot and vibration data of the end effector by using the vibration calculation model of the robot.
TRAJECTORY REPRESENTATION IN DESIGN AND TESTING OF A SURGICAL ROBOT
For kinetic sizing, the dynamic torque to be provided by a robotic system may be based off of, in part, a maximum acceleration. Rather than trying to extract maximum acceleration from many samples, a relationship of velocity to acceleration from repetitive user inputs relative to a non-surgical target in different situations (e.g., accurate, fast, or balance tracing of the target movement) is established. The velocity for any given situation may be used to estimate the acceleration from the relationship. Rather than using many trajectory samples from many users, a synthetic trajectory may be used. The synthetic trajectory may be fit to user data while maintaining high-coverage properties for direction of movement for any given pose of the robot. Alternatively, a virtual trajectory decoupled from time is used. The virtual trajectory samples the directions at any given pose in a global high-coverage manner, without specifically using a time-dependent sequence of poses.
AUTOMATIC TEST METHOD FOR RELIABILITY AND FUNCTIONALITY OF ELECTRONIC DEVICE
An automatic test method for reliability and functionality of electronic device is provided to deploy a robotic arm to perform reliability test on a tested component. In the meantime, the test host can directly access the generic log files generated by the tested electronic device without the need of using a third-party test utility on the tested electronic device. Analysis is carried out by the test host using the log files to determine whether each test round generates functional result to the tested component so that data of the functionality can be collected.
DIAGNOSTIC STATION FOR PRODUCTION LINE
A diagnostic station for inspecting an article transport vehicle movable along a guideway has a diagnostic module associated with the guideway and configured to receive the article transport vehicle when the article transport vehicle is in an inspection position along the guideway. The diagnostic module has at least one of the following: a grip testing substation having at least one force sensor configured for measuring a force exerted by a closure mechanism of the article transport vehicle in a closed position, a pressure testing substation in communication with a source of pressurized air and configured for pressurizing and depressurizing the closure mechanism, and an optical inspection substation having at least one camera configured for capturing image data of the article transport vehicle.
ROBOT CONTROL APPARATUS, MAINTENANCE MANAGEMENT METHOD, AND MAINTENANCE MANAGEMENT PROGRAM
A remaining life of a robot body is precisely estimated. A robot control apparatus 300 includes: a drive control unit 305 that controls drive of a robot body 200; a detection unit 306 that detects a feature amount quantitatively indicating a deterioration degree of the robot body 200 that is deteriorated over time as the robot body 200 is driven; a determination unit 303 that determinates presence/absence of a sign of malfunction of the robot body 200 based on the feature amount; and an estimation unit 304 that estimates a remaining life of the robot body 200 when presence of a sign of malfunction of the robot body 200 is determined.
