TOKYO -- As Mitsubishi Estate's employees start heading home in the early evening, robots get ready for work.
Whiz, a new cleaning machine developed by SoftBank Robotics, starts vacuuming the halls of the real estate company's Tokyo offices. Once a human guide manually puts it on a desirable course, the floor cleaner can repeat the path on its own using sensors and cameras. It also comes equipped with a SIM card that sends data to Brain, a U.S. artificial intelligence startup that updates the software so that it can better avoid humans and obstacles.
