Simulation of preliminary-announcement and display of mobile robot's following action by lamp, party-blowouts, or beam-light

Mobile Robot with Preliminary-Announcement and Indication of Scheduled Route and Occupied Area Using Projector

“…The first type announces the state of operation just after the present: lamp method and blowout (telescopic arrow) method, and the second type indicates the operations from the present to some future time continuously: light ray method and projection method. The effect of preliminary-announcing and indicating the upcoming robot operation, the difference according to methods, and the appropriate timing to announce have been examined by using a software simulation before the hardware equipments that made the approaches embodiment were designed and manufactured (Matsumaru & Hagiwara, 2001b;Matsumaru et al, 2003cMatsumaru et al, , 2003dMatsumaru et al, 2004). Main content to announce and display in the second type of proposed approaches is the scheduled route on running surface from the present to some future time.…”
