Robotics

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.

Sanctuary AI's Phoenix robot is very impressive, with hydraulically actuated hands that are incredibly dextrous. Well, those hands have recently become even more useful, as each one is now capable of simultaneously holding and manipulating an object.

This 125-kg (276-lb) robotic ball looks – and acts – like it could've broken free from the Batpod. It's a self-balancing sphere that can chase down criminals at up to 35 km/h (22 mph) on land or water, and strike with a range of non-lethal weapons.

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.

While autonomous flying robots have some intriguing potential applications, their usefulness is limited if they can't move across uneven terrain once they land. A new bio-inspired bot can do so, however, by mimicking the gait of the raven.

Although a number of wheeled robots can traverse uneven terrain, their body doesn't stay level as they do so, making them unsuitable for many tasks. That's where the KATR comes in, as it uses extendable legs to maintain an even cargo deck.

When most of us think of freshly poured concrete, we picture a material that should be left to dry as smooth as possible. A new robot drives right over the stuff, however, gouging its surface to make structures stronger yet also cheaper to build.

When disaster strikes, drones and robots can be sent into danger zones to scout for survivors. The RoBoa from a student team at ETH Zurich is designed to snake its way through debris that would stop other solutions in their tracks.

Various groups are now growing baby corals for transplantation into the world's disappearing reefs, but they need a hand. A new robotic hand has been created to help, by carefully transferring the li'l corals between tanks as they grow up.

China's DEEP Robotics is about to add a new quadruped to its kennel called the Lynx. But rather than go for walkies on pads, the mid-sized pup rolls on four wheels and is built for all-terrain shenanigans – as you can see in the pre-launch promo.

Today's AI technology could help robots get the hang of conducting complex surgeries. Researchers have taught a robot surgical system to expertly perform a bunch of surgical tasks as capably as human doctors, simply by training it on videos.

From washing urinals to tidying up the beach, we can already see a future where our robot servants help keep our world a little cleaner. Now, a robotic arm has mastered the surprisingly complex task of sink washing, showing off its ability to learn.

The Harmonic Drive is a key part of countless robotic applications. Incredibly simple yet quite odd to watch, this gear system is extremely precise with an impressive torque-to-weight ratio, even if it does wobble. So how does it work?

Emerging startup Physical Intelligence has no interest in building robots. Instead, the team is powering the hardware with a foundational model AI 'brain', that enables existing machines to learn and dextrously perform many tasks – including housework.

Exoskeletons have been helping paraplegic patients to walk for years, but the latest development from KAIST is a little different. The WalkON Suit F1 can amble over to a patient seated in a wheelchair, install itself, and get the user up and walking.
