Knightscope’s security robots have been on the road in Silicon Valley for years. They can see, hear and smell – and report anything suspicious to a central office. A new generation has emerged from a partnership with Samsung. The monolithic cone has become a piecemeal object. The company writes in its blog: “With its all new, fully suspended drivetrain, the K5v4 is uniquely suited to manage the more aggressive terrain outside Samsung’s Silicon Valley workplace. Since deploying, we have been able to reduce the amount of time it takes to complete a robot guard tour in areas inhibited by speed bumps, while continuing to sweep both of their multi-story parking garages for abandoned vehicles and provide their command center with the additional eyes and ears to provide more security intelligence and improve overall security.” (Knightscope, 16 June 2019) Security robots can certainly be an option in closed areas. When used in public spaces, many ethical questions are raised. However, security robots can do more than security cameras. And it is hard to escape the fourth generation.
