ウェアラブルな触覚フィードバックデバイスを用いた溶接作業の作業支援手法の基礎的検討

摘要

The aim of this study was to develop a new wearable tactile feedback device for a welder training. This study was conducted to develop the wearable tactile feedback device by using reel-to-reel microchip mounting system for fabrication. The device consisted of a vibration motor with a flexible circuit. Its effect on the welding work of trainees was evaluated. The device provided two types of vibration stimuli to the user’s forearm, based on supervised data on the welding work of an expert’s hand motion. In the experiment, we designed the welding work training trial to determine the effects of the tactile feedback device. An experiment was conducted to evaluate the effect of the tactile feedback device on welding speed performance. A beginner evaluated the welding speed generated by the tactile feedback device. The participant was required to provide perceived subjective data (easy to motion) while the welder worked with the tactile feedback device. The results indicated that the tactile feedback device enabled easy understanding of the welding velocity. In conclusion, the tactile feedback device influenced learning by using general information from manuals in welder working.%日本は超高齢社会を迎え，専門的・技術的職業従事者は減少の一途を辿っている．その中でも，溶接作業従事者の作業人口は年々減少しており，平成27年の総務省の国勢調査によると 18 万人程度まで減少していることが示されている．溶接作業は，作業の熟練度が完成度の一つの重要な指標になることから，作業人口の減少を解決することが金属溶接作業や組み立て工程において喫緊の課題となっている．
