| Outline of Final Research Achievements |
The following was done for development of a remote-controlled overhead crane liquid tank transportation system considering safety and operability.
(1)An input device that enables two-dimensional transfer operation input from an operator of an overhead crane was manufactured, and a transfer control system that suppresses liquid vibration was designed.(2)The robustness of the designed control system against changes in tank shape and rod length was verified, and the operability for avoiding obstacles was verified.(3)A remote transfer control system was constructed that ensured the magnitude of the reaction force transmitted to the operator and the stability of the system due to communication delay, and fully considered safety and operability.

天井クレーンによるタンク内液体の振動抑制制御を考察の対象とする点に本研究の特色がある．天井クレーンによる液体搬送に関する研究は少なく，ＦＭＳを指向した天井クレーンによる液体搬送を考察する研究は他には無く，その点で本研究の独創性，新規性があり，シーズ的研究であると考える．開発したシステムにより，従来，閉所内でかつ劣悪な労働条件下にあった熟練オペレータの省力化が図られ，クレーンを用いた液体搬送の場合，搬送中および搬送終了時に発生するスロッシングを抑えた最適な搬送が可能となり，生産性，労働環境および安全性の向上が図られると考える．
