Chinese company UBTECH [recently showed off]() its bipedal Walker S2 robot contorting its arms to hot swap one of its battery packs — a "world's first," seemingly — which means the 95-pound automaton could technically work 24 hours a day, an integral part of [fully automated "dark factories]()" that never need to keep the lights on. Video footage shows the robot walking up to a rack of swappable batteries. After unnaturally flipping its arms around, the automaton replaces one of its two battery packs in its back before going on its merry way. It's an impressive demo that raises some thorny questions surrounding the role of human workers in a robot-dominated future. They can already [prepare elaborate breakfasts]() and [deftly sort packages](). If they don't even need us to swap their batteries, what other responsibilities could soon be on the chopping block? https://www.youtube.com/watch?v=mHP1WGlw5Wk ## Around the Clock UBTECH's batteries take only 90 minutes to fully recharge, and the Walker S2 can walk for two hours or stand for four hours. The humanoid robot is part of an explosion in new humanoid robots hitting the market. Particularly in China, companies such as Unitree are developing increasingly affordable bipedal androids. And it's not some distant future — companies are already beginning to staff their [warehouses]() and [factories]() with humanoid bots, heralding a machine-dominated future and accelerating the timeline toward a point when conventional factory worker jobs become obsolete. That's especially true now that they're starting to learn how to even replace their own batteries: the days of factory-based grunt work could be numbered. **More on humanoid robots:** *[Wild Video Shows Humanoid Robot Preparing Elaborate Breakfast]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
