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.
-
Pleurocystitid was a marine organism that existed almost 450 million years ago, long before the first dinosaurs. Scientists have now built a soft-bodied robotic replica of it, which could inspire new methods of locomotion for future robots.
-
If a robot is trying to traverse rugged, irregular terrain, it's limited by having just one body shape. The Tetraflex robot was designed with this fact in mind, as it can change shape to adopt different modes of locomotion.
-
It goes without saying that it is very important for airliners' jet engines to be regularly inspected. Such inspections could soon be easier and more thorough than ever before, thanks to a robot that moves like an inchworm.
-
Just last week, we heard about a robotic baby sea turtle that can "swim" through the sand. It's not the only robo-turtle in town, though, as another one has been developed to possibly one day lead real baby turtles to the safety of the sea.
-
When baby sea turtles hatch from their buried eggs, they use their powerful flippers to make their way up through the sand. A new "sand-swimming" robot, inspired by those hatchlings, could one day save lives or even explore other planets.
-
While most of us may just think of krill as whale food, the tiny crustaceans are also very adept swimmers … enough so that scientists have developed a krill-inspired robotic platform in hopes of creating swarms of ocean-exploring swimming robots.
-
Although biped and quadruped robots may excel at traversing uneven terrain, they require multiple sensors and complex algorithms in order to do so. Scientists have now taken a "simpler" approach, by creating a robotic centipede.
-
When designing fish-like underwater robots, you want a means of propulsion which is both energy-efficient and reasonably speedy. A new tail-flapping system may fit the bill, paving the way for wider usage of such bots.
