    摘要: A monitoring device of a robot system including: a robot including at least one joint axis and at least one servo motor which drives the joint axis, and a controller which controls the servo motor which drives the joint axis, the monitoring device comprising: a current sensor which detects a value of a current flowing through the servo motor; a current/torque converting section which converts the value of the current flowing through the servo motor which is detected by the current sensor into a torque value; a driving torque estimating section which estimates at least a part of driving torque required to drive the servo motor; a differential torque calculating section which calculates differential torque between the torque value obtained by conversion in the current/torque converting section and an estimated value of the driving torque; an external force converting section which converts the differential torque calculated by the differential torque calculating section into an external force applied to the robot; and a stop signal generating section which generates a stop signal for the robot based on a value of the external force obtained by conversion in the external force converting section, and supplies the stop signal to the controller.

    摘要: Collision of a robot is detected by the following method. The robot includes a motor, a gear reducer connected to the motor, an encoder detecting a rotation of the motor, a temperature sensor installed to the encoder, and an object which is driven by the motor via the gear reducer. An external force torque due to a collision as a collision torque estimation value is estimated by subtracting a dynamic torque obtained by an inverse dynamic calculation of the robot from a torque output to the gear reducer by the motor. It is determined that the robot receives an external force if the collision torque estimation value is greater than a predetermined collision detection threshold. The predetermined collision detection threshold is set to a first value in a case where a temperature detected by the temperature sensor is less than a predetermined temperature threshold. The predetermined collision detection threshold is set to a second value less than the first value at a first time point at which the detected temperature is equal to or greater than the predetermined temperature threshold in a case where a maximum value of the collision torque estimation value is less than a first maximum value determination threshold in a period to the first time point from a second time point prior to the first time point by a predetermined length of time. The predetermined collision detection threshold is set to the first value at the first time point in a case where the maximum value of the collision torque estimation value is equal to or greater than the first maximum value determination threshold in the period.

    摘要: The present invention relates to an industrial robot system comprising a movable platform (1), an industrial robot (2) located on the movable platform, a sensor system comprising two sensors (4, 5) arranged to detect motions of an object within at least one safety zone (A, B) defined in relation to the sensors, and a safety control unit (7) configured to adjust the speed of the robot if a moving object is detected in the at least one safety zone. Each of the sensors is configured to detect motions within an angle of at least 90° in a horizontal plane. Each of the sensors (4, 5) are arranged so that their positions are adjustable in relation to the movable platform between a first position on or in close vicinity of the movable platform, and a second position located at a distance of a least 0.5 m from the movable platform (1).

    摘要: A safety device for a mechanical motion device and a method for protecting a person or object in the vicinity of a mechanical motion device are described herein. The safety device may include: a shroud; a coupling mechanism; and a detection device. The coupling mechanism joins the shroud in a displaceable manner to a mechanical motion device. The detection device is configured for communication with the safety control system of a mechanical motion device. The detection device is capable of detecting misalignment of the shroud from its initial aligned position and/or a collision between the shroud and a person or object. The detection device may send a signal to the safety control system of the mechanical motion device to at least slow the movement of the mechanical motion device before the mechanical motion device reaches the location of the collision of the shroud with an object or person.
