July 7, 2014

By a News Reporter-Staff News Editor at Robotics & Machine Learning -- A patent by the inventor Sueyoshi, Satoshi (Fukuoka, JP), filed on December 16, 2011, was published online on June 24, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8761929 is assigned to Kabushiki Kaisha Yaskawa Denki (Kitakyushu-Shi, JP).

The following quote was obtained by the news editors from the background information supplied by the inventors: "Conventionally, there is known a robot system that instruct a robot by a controller controlling the robot to move a work into and out of a container or the like.

"For example, Patent Document 1 proposes a robot that vertically moves by moving a leg unit and conveys a thin-plate like work, such as a semiconductor wafer, by an arm unit arranged in the upper portion.

"Examples of documents related to the above-described conventional technology include Japanese Patent No. 4466785.

"However, when performing a maintenance operation of a robot included in a conventional robot system, the operation needs to be performed by using heavy machinery such as a crane for lifting heavy goods. Therefore, there is a problem in that it takes time to prepare heavy machinery and perform an actual operation.

"For example, when replacing a heavy part such as a motor included in a conventional robot, it takes a long time, for example, to carry in and carry out a crane, ensure working space, and mount and remove jigs."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "A robot system according to an aspect of embodiments includes a robot and a control unit. The robot includes a plurality of movable units that operate in a predetermined direction and links connected to the movable units, and the control unit controls an operation of the movable units of the robot. Moreover, the robot system transfers a detachable member mounted on a predetermined movable unit by causing a movable unit other than the predetermined movable unit to operate in a state where the predetermined movable unit is stopped."
