'Dystopian world': Singapore patrol robots stoke fears of surveillance state

Singapore has trialled patrol robots that blast warnings at people engaging in "undesirable social behaviour", adding to an arsenal of surveillance technology in the tightly controlled city-state that is fuelling privacy concerns. From vast numbers of CCTV cameras to trials of lampposts kitted out with facial recognition tech, Singapore is seeing an explosion of tools to track its inhabitants. That includes a three-week trial in September, in which two robots were deployed to patrol a housing estate and a shopping centre. 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. Singapore is frequently criticised for curbing civil liberties and people are accustomed to tight controls, but there is still growing unease at intrusive tech.
