Amphibious

Turkish startup SealVans has launched two amphibious caravan models that combine the features of a boat and a traditional caravan. The amphibious vehicles are a unique solution for adventurous families who want to explore both land and sea.

On the tip of a multi-vehicle offensive meant to fill in some market gaps, ARGO is launching the all-new Sasquatch XTX. The high-riding amphibious swamp machine rolls and swims with 71-inch tires, carrying a full pickup box for maximum utility.

Robots that move across both land and water are potentially very useful, but they also tend to be complex and rather slow. A new bio-inspired amphibious bot, however, utilizes a relatively simple mechanism to undulate at a good clip.

While aerial drones can travel long distances quickly, aquatic drones can explore underwater environments. The TJ-FlyingFish offers the best of both worlds, as it's a flying quadcopter that is also able to make its way through the inky depths.

Florida company Poseidon Amphibworks is raising money toward a prototype of its Trident LS-1. This electric, AWD three-wheeler will be capable of highway speeds on land, and it'll extend its range capabilities in the water using low-drag hydrofoils.

We've been following Iguana Yachts for over a decade – from tenders to taxis to sprinters, all rolling to the water's edge on retractable caterpillar tracks. Now the company is looking to fly above the waves with the launch of the Iguana Foiler.

The Scoter amphibious caravan isn't as large or pretty as the Caracat cat-camper, but it boasts a slick feature. The tri-camper's built-in wheels fold into the hulls, ensuring smooth flotation while eliminating the need for a separate trailer.

If you're going on a self-propelled river journey, is it really self-propelled if someone drives you back when you're done? Perhaps not – and that's why inventor Ben Kilner created a paddleboard/bike-and-trailer combo known as the Duckleberry Finn.

The Caracat is the latest land/water RV, combining a stable, electric-propelled boat platform with camper van features like a pop-up roof and convertible furnishings. Don't let shorelines end your adventure – camp on "sea, lake and land."

Ghost Robotics' Vision 60 quadruped robot is already quite a versatile beast, capable of walking, running and even carrying a gun. Now, thanks to a third-party attachment, it can also "swim" through the water.

Although aerial drones can travel much faster than their underwater counterparts, they certainly aren't as good at gathering water-related data. The MEDUSA multi-rotor drone addresses this conundrum, by landing on the water and deploying an underwater pod.

When mines extract oil or ore from other materials, they generate liquid waste known as tailings. This waste is stored in tailings ponds, which have to be monitored – and that's where the amphibious Helix Neptune robot is designed to come in.
