The K5, a security robot, comes from Knightscope in Silicon Valley. It can be seen there regularly. It provides, e.g., security at the Stanford Shopping Center. The conical robot is autonomous. It can see, hear, and even smell smoke and gas. The classic security robot also made it to Hawaii (Hawaiian: Hawai’i), for the first time in 2021, according to the Khon2 platform: „There is a new security guard getting a lot of attention at the Financial Plaza of the Pacific in downtown Honolulu, but it is not what you would think — it is actually a robot and the newest member of Bank of Hawaii’s security force. It looks like something out of a sci-fi movie – only it is actually real. Currently, the security robot is patrolling the busy area in and around the Bank of Hawaii’s Financial Plaza on Bishop and Merchant streets. For many people, the robot is a curiosity – attracting lots of odd looks – with some people capturing video and even posing for selfies. But many others, like Nasir Randall, are not quite sure what to make of it.“ (Khon2, 28 October 2021) Security robots, along with cleaning robots and transport robots, are among the service robots that are largely error-free and already saving money. Over the next few years, they are likely to become widely used and accepted around the world.
