Many kinds of preparations are needed when meeting. For example, projector, laptop, cables and ETC. As such, this video have constructed Meet AR-bot, which helps users to keep meeting going smoothly, based on the projection of Augmented Reality(AR). Our system can easily provide meeting room environment through the movable setting via wheel-based stand. Users do not need to carry a personal laptop and connect them to the projector. Robot reconstructs the 3D geometry information through pan-tilt system and compute projection areas to project information in the space. Users can also control through mobile devices. We offer presentation, table interaction, file sharing and virtual object registration by mobile device.
