Restaurant cat robot meows angrily at diners

A robot cat designed to ferry plates of food to restaurant customers has been unveiled at the CES tech expo in Las Vegas. BellaBot, built by the Chinese firm PuduTech, is one of a number of wacky robotic inventions being shown off at the event this year. There is also UBTech's Walker, which can pull yoga poses. It speeds a roll of toilet paper on demand to bathrooms that have run out of the stuff. One expert said it was likely that robots exhibited at CES would only continue to get more bizarre in the future. BellaBot, the table-waiting robot cat, is a service bot with personality.
