The H7 robot walks without a safety harness at the Inoue-Inaba Robotics Lab. A joystick operating student, seated at right maneuvers the robot. Research Associate Satoshi Kagami (wearing a suit in the photo) walks with the robot, armed with its "kill switch" in case the robot malfunctions. Its predecessor, H6 hangs at left, near another student who is ready to step in, in the event that the robot falls. The researchers are fairly relaxed during the demonstration compared to those in other labs. University of Tokyo, Japan.
