Bizarre stork robot uses a drone to compensate for its weak, twig-like legs

Aerial-Biped: a new physical expression by the biped robot using a quadrotor

We can be suckers for weird robots here at Digital Trends — and they don’t get much weirder than this “Aerial-Biped” robot developed by engineers from Japan’s University of Tokyo. Halfway between a drone and a ground-based robot, the Aerial Biped’s body is comprised of a quadrotor UAV (unmanned aerial vehicle) that remains rooted to the ground with thin, stork-like legs.

On a technical level, Aerial Biped is pretty smart. Its walking motion isn’t preprogrammed, but rather the result of a type of artificial intelligence called reinforcement learning. That’s the same type of goal-based A.I. that helped Google DeepMind learn how to play classic Atari games based on nothing more than the visible information on screen. In this case, the robot uses information about the forward velocity of the quadrotor to figure out how it should use its legs.

The idea behind the robot’s design was to create a robot that won’t ever fall over, since its upper body will remain airborne at all times. As we saw when Boston Dynamics’ Atlas robot fell off the stage during a demo last year, even the most sophisticated robots are capable of taking a tumble. As a result, many researchers (including those at the University of Tokyo) are working to come up with alternative designs to the traditional humanoid robots long imagined by science fiction writers. Aerial Biped may not be practical as, say, an equipment carrier, but it’s certainly a unique way of getting around the problem of stability.

Right now, Aerial Biped exists purely as a proof of concept prototype that’s designed to explore this form of locomotion. In the future, however, its creators believe it could be used in an entertainment capacity, potentially for animatronics or various types of performance. With that goal in mind, they are currently investigating different types of motion that it could perform — including a variety of dances.

While it’s highly unlikely that we’ll see robots such as this one ever used in military applications, or as part of search and rescue missions, it’s very easy to picture it finding a future summer job at somewhere like Walt Disney World. Hey, who said all robots needed to be serious?

Global EV sales expected to rise 30% in 2025, S&P Global says

While trade wars, tariffs, and wavering subsidies are very much in the cards for the auto industry in 2025, global sales of electric vehicles (EVs) are still expected to rise substantially next year, according to S&P Global Mobility.

"2025 is shaping up to be ultra-challenging for the auto industry, as key regional demand factors limit demand potential and the new U.S. administration adds fresh uncertainty from day one," says Colin Couchman, executive director of global light vehicle forecasting for S&P Global Mobility.

Given existing tariffs and what’s in store from the Trump administration, you’d be forgiven for thinking the global race toward lower electric vehicle (EV) prices will not reach U.S. shores in 2025.

After all, Chinese manufacturers, who sell the least expensive EVs globally, have shelved plans to enter the U.S. market after 100% tariffs were imposed on China-made EVs in September.

With 2024 behind us, all eyes in tech turn to Las Vegas, where tech monoliths and scrappy startups alike are suiting up to give us a glimpse of the future. What tech trends will set the world afire in 2025? While we won’t know all the details until we hit the carpets of the Las Vegas Convention Center, our team of reporters and editors have had an ear to the ground for months. And we have a pretty good idea what’s headed your way.

Here’s a sneak peek at all the gizmos, vehicles, technologies, and spectacles we expect to light up Las Vegas next week.
