Secom Robot X
Secom's Robot X is a security robot that can run as fast as humans and scare away intruders by spraying white smoke. It's designed for use at spacious places such as airports and factories and will be leased for 300,000 yen per month, starting next fiscal year, Secom said. The four-wheeled robot is about one meter long and high and weighs 120 kilograms.
