  • Patent number: 11045954
    Abstract: A plurality of robots each has a plurality of control modes including an automatic mode, a manual mode, and a corrected automatic mode in which the robot operates based on a task program while being sequentially corrected by the operator's manipulation. A first robot performs a first work to a work target in one of the corrected automatic mode and the manual mode, location data of the work target in a robot coordinate system of the first robot is acquired. Based on the location data of the work target in the robot coordinate system of the first robot and a relative relation between the robot coordinate system of the first robot and the robot coordinate system of the second robot, location data of the work target in a robot coordinate system of a second robot is corrected.

  • Patent number: 10994412
    Abstract: A robot control device having a drive shaft driven by a servo motor including a non-excited operation type electromagnetic brake. The electromagnetic brake is configured to perform a braking operation by pressing an armature against a friction plate by an urging force of a spring when an excitation coil is not energized, and to cancel a brake operation by attracting the armature to the excitation coil side against the urging force of the spring to separate the armature from the friction plate when the excitation coil is energized. A coil current flowing through the excitation coil is obtained and the robot is controlled based on the characteristic of time change of the obtained coil current. A robot control device capable of shortening a cycle time, estimating the life of the electromagnetic brake, performing abnormality diagnosis and the like with a relatively simple configuration can be provided.
