Hoteliers would like to employ more robots

IN A recent blog post, Gulliver expressed his exasperation at having to interact with other humans when he stayed at hotels. After all, in the age of mobile check-in and automated bartenders, it must be possible to swerve most of these pointless encounters (and avoid having to hand over tips for the most mundane services, such as pouring a beer or being shown to your room). One solution that didn't occur to him was robot butlers. The M Social Singapore hotel is introducing a droid that can deliver room service to guests. It navigates using 3D cameras and can negotiate lifts and manoeuvre around people wandering down the corridors.
