Aerial jetpacks may still not be readily available, but underwater jetpacks? Those are another story. The relatively affordable XiaoTun is the latest to cross our radar, shooting wearers up to a maximum submerged speed of almost five feet per second.

Some 14 years after it was first revealed, the ambitious plan to create a self-filtering floating pool in a New York City river is now finally under construction. + Pool is expected to begin initial testing in 2026.

While we've seen a number of wearable underwater propulsion systems, they've typically been strapped to the user's arms or legs. The newly refreshed CudaJet is different, in that it's a true backpack-style underwater jetpack.

Quadruped "robot dogs" may move quite a bit like their canine counterparts on land, but they're not nearly as good at swimming (although some can walk underwater). Such is not the case with a new mini-dog-bot, however, which is an expert at doing the dog-paddle.

Dubai authorities have revealed an ambitious plan to build what they call the world's tallest resort, an incredible new 328-ft-tall attraction that will incorporate waterfalls, swimming pools, and the world's largest indoor botanical gardens.

If you're setting out to build an underwater robot that's speedy, maneuverable and versatile, why not just copy what already works in the natural world? That's exactly what Beatbot has done, with its bio-inspired Amphibious RoboTurtle.

It was just two years ago that a tiny robotic manta ray became the world's fastest-swimming soft-bodied robot. Well, one of its descendants has now smashed that record – and it uses less energy than its predecessor, to boot.

French company Seabike has developed a swimming device that uses your own leg power to accelerate you through the water at superhuman speeds. This crank-driven pusher prop looks a bit like an underwater unicycle... We'd love to take one for a spin!

If you're looking for a hands-free wearable electric boost while snorkeling or scuba diving, the Jetdive Pro should definitely fit the bill. It's not the first product of its kind, but it is claimed to be the best in several key ways.

Could you throw a lifebuoy all the way out to a distressed swimmer located one kilometer away? Nope, you couldn't … but you could fly one out to them, in the form of the TY-3R Flying Lifebuoy drone.

We’ve tested 50 different waterproof headsets over the years, and a clear favorite emerged when Zygo launched its headphones. This week a 2nd-gen Zygo was announced, with enhanced audio, longer range, longer battery life, and on-the-go charging.

A new underwater robot can swim through the water with fins, and walk or crawl along the bottom when necessary. These capabilities could really give it a leg up – pun fully intended – at outperforming its traditional thruster-powered counterparts.
