Here’s a robot that will roam your home or office seeking intruders. The Searching Security Robot was designed by Ian Smith and his fellow students in a mechatronics’ course at Colorado State University. It sits on motor-powered wheels and its eyes consist of an ultrasonic range finder to keep it from bumping into walls. Once it’s set up, the robot will roam a building seeking moving objects. It has four infrared sensors that detect motion in 360 degrees. When a moving object is detected, the robot sounds its alarm.

Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
