Despite what you might say when drunk, you’re not the best backflipper in the world. That honor belongs to a tiny little bug called a globular springtail, whose superfast backflips have now been caught on slow-motion camera for the first time.
-
Snails are great at climbing vertical surfaces, even though they have just a single wet suction-cup foot. A new robot climbs walls by mimicking that simple yet effective mechanism, although thankfully it leaves a trail of water instead of mucus.

You might think that having four legs with wheels on the ends would already make a robot pretty useful. China's LimX Dynamics is taking things further, however, as its W1 quadruped robot is now able to stand up and walk on two "feet."

If a soft-bodied robot uses rigid actuators to move its body, then it isn't really soft now, is it? An experimental new caterpillar-inspired bot gets around that conundrum by using soft, collapsible origami segments to squirm and steer its way into our hearts.

Even though snails are slow and slimy-bottomed, they've inspired a new type of robot that could be quite useful. Groups of these bots can operate independently or join together in order to perform tasks that would otherwise be impossible.
-
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.

It might look hilarious in motion, but this remarkable aerial drone extends its battery life from a few minutes up to a full hour by bouncing around on a springy pogo tail. That incredible efficiency makes it attractive for a wide range of missions.

A three-legged robot could one day be hopping across the surface of asteroids, searching for valuable minerals. Known as the SpaceHopper, the bot was recently put to the test on a zero-gravity aircraft flight.
-
Danish scientists have developed an origami snake robot that could one day search for survivors at disaster sites, or even explore other planets. The device moves via rectilinear locomotion, just like real snakes often do.
-
Water striders are fascinating to watch, as they scoot across the water while supported by surface tension. Scientists have now built a tiny robotic version of the insect, which utilizes a record-breaking actuator to get a move on.
-
When we last heard from LimX Dynamics, the Chinese robotics firm was showing off a quadruped robot that could walk on legs or roll on wheels. The company has now released a video of its new humanoid robot, which can autonomously climb stairs.

Walking bipedal robots excel at tasks such as traversing uneven terrain, but because they're so mechanically complex, they can't be made very small. That could soon change, however, thanks to the development of the Mugatu robot.
