So many robots work at Changi General Hospital in Singapore that until recently it wasn’t uncommon to find two delivery bots sitting in a hallway or outside an elevator in a standoff.
Such impasses used to happen “several times a day,” says Selina Seah, who directs the hospital’s Center for Healthcare Assistive and Robotics Technologies. Unsure how to move around another object, or human passersby, the robots would simply freeze, each waiting for the other to move first. “The humans would have to actually go down and pull them apart,” she says.
