Hopefully sooner rather than later, all these domesticated, master-serving robots will be able to handle even the most mundane of tasks for us without botching our reputations, like holding down the 9-5 for us while we tee it up. Until then, however, we'll have to be satisfied with a household bot that not only recognizes our face, understands hand gestures, and follows us around to see if we need help, but chases foes away too. A team of researchers at Hsinchu-based National Chiao Tung University (NCTU) has developed just the companion, and this motorized fellow (or dame, whichever you prefer) sports a unique "digital vision system" that gives it the ability to "not only to remember the master, but also recognize his or her gestures and offer services accordingly." Moreover, it can reportedly judge the person's current health condition by analyzing facial expressions, and can then proceed to fetch medicine, a telephone, or another person in the home to provide aid. Clearly designed to assist the elderly, which could have difficultly caring entirely for themselves, the NCTU Vision One can reportedly distinguish between intruders and family members, and it can even be set to chase away the baddies while taking pictures of him / her for future prosecution purposes. While we've no idea if this classroom invention will ever hit the production line, this thing is a kitchen sink away from being the whole enchilada, and the whole "chasing function" simply makes this a must-have if it eventually comes to market.
