The robo-security guard that hunts intruders using LASERS: Droid can spot suspicious behaviour and call for back up

Even the smartest of intruders would struggle to slip past this security guard. Armed with lasers and infrared cameras, a new security robot is promising to take over the tedious task of patrolling buildings. RAMSEE can provide round-the-clock monitoring of an area by scanning its environment as it trundles through rooms, looking for motion, along with signs of fire, smoke and gas leaks. Lidar is a remote sensing technology that measures distance by shooting a laser at a target and analysing the light that is reflected back. The technology was developed in the early 1960s and uses laser imaging with radar technology that can calculate distances. It was first used in meteorology to measure clouds by the National Center for Atmospheric Research.
