Knightscope is the five foot tall robot security guard that's being rolled out across Silicone Valley. The Knightscope K5 robot security guards are 5ft tall robots that come with GPS, lasers, and heat-detecting technology. They are designed to function without any human manipulation and are built with surveillance cameras and sensors, odor detectors, thermal imaging system, and scanners which can read an impressive number of 300 car registration plates every single minute. When on a patrolling duty, it uses lasers to calculate the distance and also relies on its GPS system. Credit: Knightscope, Inc.
