Breakthroughs, discoveries, and DIY tips sent every weekday. A Jetsons-style Rosey household assistant robot may finally be a reality--only it probably doesn't look quite like you would expect. In fact, the contraption in question more closely resembles a custodian's mop and bucket. Though it might not be much of a looker, researchers from the Suzhou Industrial Park Institute of Vocational Technology and Xi'an Jiaotong-Liverpool University in China say their robot design can autonomously steer clear of most large furniture and children. It can even pick up loose toys and sort through smelly socks--at least some of the time.
