|An unmanned flight robot|
The robot returns to the base automatically when the battery runs out. The operator can fly it again after he replaces the battery with a new one. Prof. Nonami is now developing a technology to allow the robot to go down to the ground with the help of a parachute when it goes out of control while flying. It is designed to inspect the deterioration of such infrastructures as solar panels of photovoltaic generation, windmills of wind generation, bridge beams, and piping of iron works. It will be put on the market next spring.
