Knightscope’s answer to the growing security problem is the K5 and its smaller version, K3, which can recognise people, speak to them via recorded messages and read licence plates. The 5-feet tall and 3-feet wide dome-headed, wheeled robot uses 360-degree video cameras, 16 microphones, thermal imaging and sensors. It gathers real-time data from a site and transmits it back to security professionals to monitor. The robots, which can operate on wireless or cellular network, after patrolling for couple of hours, can autonomously find and dock itself to a charge pad for 10 to 20 minutes. “The idea is to provide 100% uptime for our clients,” says Li. Though the robots can technically go up to 18 mph, they are programmed to move in the 1-3 mph range, depending on the vicinity. The global positioning system and the laser ranging instrument help the robots to avoid obstacles and find their way around on its own. The K3 and K5 robots generate over 90 terabytes of data per machine, every year, providing an unprecedented ability to understand the environment at all times. The robots can be remotely monitored and scheduled to conduct different types of patrols depending on the clients’ need and nature of business. “Our technology stack is analogous to that used in self-driving cars, (which is still in trial stage), but we have already commercialised the autonomous technology from 2015 and is being used by real clients,” points out Li, who has a 25-member team comprising 8 Indians, who are mostly engineers.
