Singapore (AFP) – Hi-tech Singapore has deployed an autonomous robot with a swivelling camera for a head and flashing lights to patrol a summit venue — arresting the attention of amused passers-by who stopped to snap selfies. The white, four-wheeled buggy, measuring about five-feet (1.5 metres), trundled around the perimeter of a convention centre in the city-state, providing additional security at a meeting of world leaders. The so far unnamed robot, decked out with flashing blue and red lights, is a prototype reportedly developed by the police, which can transmit a 360-degree picture of the area it is patrolling.
