Singapore trials patrol robots to warn people of "undesirable" behavior: "It reminds me of Robocop"

Singapore — Singapore has trialed patrol robots that blast warnings at people engaging in "undesirable social behavior," adding to an arsenal of surveillance technology in the tightly controlled city-state that is fueling privacy concerns. From vast numbers of CCTV cameras to trials of lampposts kitted out with facial recognition technolgy, Singapore is seeing an explosion of tools to track its inhabitants.

Officials have long pushed a vision of a hyper-efficient, tech-driven "smart nation," but activists say privacy is being sacrificed and people have little control over what happens to their data.
