Most of the other bots were already known, such as the Human Support Robot (for guiding people to their seats), the Delivery Support Robot (drinks and other orders) and the T-HR3 humanoid robot (remote interactions with athletes).

However, there will be one more Olympics-specific bot. The Mascot Robot in Miraitowa and Someity variants (you're looking at Someity below) will welcome people to venues through object detection and remote-controlled limbs. Toyota is also "considering" a way to enhance the games for Japanese kids through the mascot machines.

The robots serve as marketing material for Toyota and Japan's technology industry as a whole. Like other Japanese worker robots, though, they're also an acknowledgment of the country's labor shortages. With a declining population and a reluctance to invite foreign workers, the country can't always count on having enough people to fill jobs. The Field Support Robot and its peers could ensure that Tokyo 2020 proceeds without a hitch, even if there aren't as many human staffers as the organizers would like.
