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.

An accelerated life test method for a speed reducer of an industrial robot is provided. The accelerated life test method includes: setting first load stress higher than rated load stress and second load stress lower than the rated load stress; performing an accelerated life test by loading the first load stress to first speed reducer samples; calculating a service life of each of the first speed samples in the accelerated life test; performing a contrast test by loading the second load stress to second speed reducer samples; calculating a service life of each of the second speed samples in the contrast test; and calculating an acceleration coefficient, and the acceleration coefficient is equal to a ratio of the service life in the accelerated life test to the service life in the contrast test.

Embodiments of the present invention provide methods and systems to analyze wearable technology. A robot with snake assembly works in conjunction with a server in order to simulate the locomotive actions of appendages and to concomitantly determine the response of wearable technology devices, which are attached to the snake robot assembly, to the simulated locomotive actions.

A failure diagnosis support system includes first image acquisition means mounted on a robot for acquiring an image of the robot; and control means for controlling position and orientation of the first image acquisition means. The control means controls the position and orientation of the first image acquisition means at a predetermined timing so that the first image acquisition means faces a predetermined part of the robot. The first image acquisition means acquires an image of the predetermined part at the position and orientation controlled by the control means.

In an approach to non-functional requirement stimulus testing of a robot, one or more computer processors receive one or more stimulus parameters to test. The one or more computer processors trigger the one or more stimulus parameters in the robot. The one or more computer processors determine at least one response time to the one or more stimulus parameters.

In an approach to non-functional requirement testing of a robot, a computer determines one or more kinematic actions included in a received command. The computer determines at least one component of the robot included in an operation of the one or more kinematic actions. The computer determines at least one agent associated with the at least one component of the robot included in the one or more kinematic actions. The computer sends the one or more kinematic actions to the robot. In response to the robot performing the one or more kinematic actions, the computer receives, from the at least one agent, at least one characteristic of the performed one or more kinematic actions associated with the at least one component of the robot included in the one or more kinematic actions. The computer, based on the received at least one characteristic, generates one or more test results.

A force/torque sensor includes a number n of deformable beams connecting the TAP to the MAP, wherein n4. At least four of the n deformable beams are instrumented with strain gages affixed to surfaces of the beams, such that each beam outputs two gage signals. The eight gage signals are grouped into four sets of six gage signals, such that each set includes the gage signals from three of the four instrumented beams. Each set of six gage signals is multiplied by a calibration matrix to yield a set of six force and torque values. The four sets of force and torque values are compared. If one set disagrees with the other three by greater than a predetermined tolerance, a sensor fault is signaled.

A tool for providing an electrical interface between a motor circuit analyzer having a plurality of motor circuit analyzer connection ports and an electrically operated machine having electrical devices and a multi-conductor cable comprising electrical wires connected to the electrical devices. The tool includes a plurality of tool connection ports configured to be electrically connected to motor circuit analyzer connection ports. The tool also includes a plurality of terminals configured to be electrically connected to the conductors of the multi-conductor cable, and a switching section configured to selectively electrically connect two of the plurality of tool connection ports to two of the plurality of terminals.

A diagnostic device may be used for a link actuation device. A distal end side link hub may be coupled to a proximal end side link hub via three or more link mechanisms such that posture of the distal end side link hub can be changed. Each of the three or more link mechanisms may be associated with a respective one of actuators. A predetermined action may be carried out under a predetermined condition by driving each of the actuators. A preload applicator may cause a preload to be applied to the link actuation device. A torque detector may detect a drive torque of each of the actuators while a preload is being applied. A determiner may determine whether or not the torque that is detected by the torque detector lies within a predetermined range. A notifier may notify the determination result.

A detection device and a detection method are provided for robot-induced loads that can act upon the human body in contact with the robot during a working process. The robot-induced loads, in particular forces, are measured by the measuring device (16) of an external sensing device (2). The measuring device (16) is suitably positioned and oriented in this process in the working area of an industrial robot (3) by means of a positioning device (15).
