LG said it had big plans for its robots at CES, and it wasn't kidding around. The tech giant has unveiled a handful of robotic helpers that clearly go well beyond vacuums. To start, it's introducing the Hub Robot and its Mini-size counterpart. They can control your smart home devices, play music, offer advice on commuting times and otherwise make your life a little easier, all while offering a friendly face. It basically amounts to an Amazon Echo with cute expressions, but that's not necessarily a bad thing. And, importantly, they're not alone -- they have a much bigger sibling.
