  • Publication number: 20250083326
    Abstract: An end effector includes a base portion, an imaging apparatus supported by the base portion, and a tool movably supported by the base portion, the tool being configured to support a workpiece and perform work with respect to the workpiece. The base portion includes a driving mechanism. In a case of capturing an image of an imaging object by the imaging apparatus, the driving mechanism is configured to position the tool supporting the workpiece outside of a range in which at least part of the tool or the workpiece supported by the tool overlaps with the imaging object in a field of view of the imaging apparatus.

  • Patent number: 11267126
    Abstract: Force sensors capable of measuring only forces in xyz coordinate axis directions are installed in fingertips, respectively, and forces and moment forces acting on a robot hand are calculated based on positional information about each fingertip. This structure eliminates the need for using large force sensors to thereby enable downsizing of each fingertip, and enables detection of loads and moment forces acting on the robot hand.

  • Publication number: 20220016789
    Abstract: A tool stocker for holding a tool is equipped with a stocker-inclining member that inclines the tool stocker and also equipped with a mechanism that adjusts an attaching/detaching position at which an interchangeable tool is attached to and detached from a robot arm. The attaching/detaching position can be adjusted by using the tool stocker so as to fit moving paths of the robot arm appropriately.

  • Patent number: 10363660
    Abstract: A method of controlling a robot system including an articulated robot and a control device is provided. The articulated robot includes links connected by joints, motors configured to drive the joints respectively, and detection devices configured to detect rotation amounts of the joints respectively. The control device controls the motors. The method includes the steps of, by the control device, recording movement information of the joints based on outputs of the detection devices; when detecting an abnormality in the operation of the articulated robot, determining presence or absence of a failure in the articulated robot based on the movement information recorded in at least a period from before detection of the abnormality until detection of the abnormality; and specifying a failure portion of the articulated robot if it is determined that there is a failure in the articulated robot in the step of determining.

  • Patent number: 9346173
    Abstract: A robot, includes: a robot arm including: a first frame; and a second frame coupled to the first frame to be turnable about a joint axis; a cable arranged along a side surface of the first frame and a side surface of the second frame; a first fixing member for fixing the cable to the side surface of the first frame; a second fixing member for fixing the cable to the side surface of the second frame; a holding member for holding a part of the cable between the first fixing member and the second fixing member; and a support mechanism for regulating movement of the holding member in an axis direction of the joint axis, the support mechanism supporting the holding member so that the holding member is movable in a direction orthogonal to the axis direction of the joint axis to follow a bending movement of the cable.
