  • Publication number: 20150343639
    Abstract: A gear incorporation system includes a robot to hold a gear from among gears including first and second gears that are not to be engaged with each other. The robot moves and attaches the gear to an attachment position. A control apparatus controls the robot and includes a first determiner, a temporary placer, and a turner. The first determiner determines whether the gears include an intermediate gear that is to be engaged between and with the first and second gears. When the first determiner determines that the gears include the intermediate gear, the temporary placer controls the robot to give priority to the first and second gears to attach them to respective attachment positions, and then to temporarily place the intermediate gear on the attachment position. The turner controls the robot to turn one of the first and second gears by a slight amount.

  • Publication number: 20150045953
    Abstract: A robot system includes a robot and a controller. An arm includes joints. Actuators drive the joints. Sensors detect operation states of the actuators. The probe is mounted on the arm. A force sensor detects force received by the probe. The controller controls the robot. A determinator determines whether the force from a structure disposed at a position on a work stand satisfies a condition. An operation state acquisitor acquires the operation states when the force satisfies the condition. A coordinate calculator calculates a position coordinate of the probe based on the operation states. A position correction amount calculator calculates a correction amount of a position of the work stand relative to the robot based on the position coordinate.
