Though if I would work in such office, personally it would be rather awkward and cringeworthy experience on either end.
And the video did not show any advantages against classic conference video call (it wasn't the goal of a video, but if there would've been more uses for it, then it would've shown in the video). You basically just can wander around the office in glorified RC vehicle, drive into the conference room and chat during a meeting.
Don't most laptops these days have an integrated camera?
I couldn't imagine using one of those robot to participate in a discussion with 15 people in the same room, and being the only remotee.
