In schools and other educational institutions, there are many opportunities to carry classroom chairs according to purpose. Some chairs are on casters, but educational institutions typically use stacking chairs or folding chairs. Although effective in terms of storage, it must be lifted by hand during transportation, increasing the burden on workers. Automation of baggage transport in warehouses has improved significantly, but little attention has been given to chair transport automation. Self-propelled chairs were developed, but despite the need, automatic transport of chairs without casters was not noted. In this study, we constructed an automatic chair movement system using an omnidirectional mobile robot. Recognize the chair by image processing and bring the robot closer. After the robot dives under the chair, the chair is lifted and transported using a lifting device attached to an omnidirectional robot.
