A robot that copies how cockroaches and geckos can disappear under ledges in the blink of an eye could lead to search-and-rescue droids with animal-like maneuverability,

ScienTIsts regularly look to nature for inspiraTIon when designing robots, with the hope of learning from millions of years of evoluTIon. Recent examples include droids that mimic the cheetah's stride or the legs of velociraptor.

While monitoring a cockroach with high-speed video cameras to see how it crossed gaps while running at high speeds, "we were surprised to find the insect gone," said researcher Robert Full, an integraTIve biologist at the University of California at Berkeley.

"After searching, we discovered it upside-down under the ledge," Full said. "After close inspection of the video, we saw that the cockroach was using its legs as grappling hooks by engaging its claws at the tip of the ledge."

The scientists then saw that geckos in the lab could also run off ledges at full speed and carry out this pendulumlike flip, dubbed "rapid inversion," using hooklike toenails to swing themselves fully around to land firm on the undersides of platforms. Contacted integrative biologist Ardian Jusufi who was studying geckos in the field in the rainforests of Singapore to see if the lizards dove over ledges the same way in the wild.

"We found that whether a was really used in nature to escape predators," Full said. "To his surprise, he found that a gecko chased to the end of a broken Bird's Nest Fern leaf also disappeared. Using high-speed video, He showed that geckos used rapid inversion, just as observed in the laboratory."

Apparently the animals can grab an edge with their claws — sometimes using only one leg, in the case of roaches — and retain 75 percent of their running energy as they swing like pendulums beneath it. They experience about three to five times the force of gravity With the flip, similar to what humans feel at the bottom of a bungee jump, said researcher Jean-Michel Mongeau at the University of California at Berkeley.

The findings modified only six-legged cockroach-inspired DASH — Dynamic Autonomous Sprawled Hexapod — by attaching Velcro hooks to its After legs glued Velcro loops near and underneath a ledge, they found DASH could duplicate the acrobatic move.

"The flip demonstrates a principle of how we might make small robots more agile and maneuverable," Full said. "Ultimately, if we want search-and-rescue robots to assist first responders in the rubble left after an earthquake, tornado or explosion, Or have greater capability to more rapidly detect chemical, biological or nuclear hazards, we must build far more agile robots with animal-like maneuverability."

After cockroaches and geckos flip over ledges, they can then continue to run upside-down under surfaces. "The robot might be able to do so in the future" as well, Full said.

The scientists detailed their findings online June 6 in the journal PLoS ONE.

This is the American cockroach on the next window sill.

The how the scorpion and gecko can disappear in the blink of an eye sill may lead to robots that search and rescue robotic animal-like mobility, the researchers said.

Scientists often look for the inspiration of nature when designing robots, with the hope of millions of years of evolutionary learning. Recent examples include imitating the cheetah's stride and the rapid leg robot.

When monitoring the high-speed camera to see how it was running at the same time at high speeds, and crossing the gap, we were surprised to find the bug, said researcher Robert Complete, a comprehensive biologist at the University of California at Berkeley.

After searching, we found that its window sill was upside down, all said. After a careful examination of the video, we saw that the leg that used it was grasping the hook at the corner of the window sill by participating in its claws.

Wrong juice: When it comes to living fuel cells Bug Juice: Turning Roaches into Living Fuel Cells, scientists see that in the laboratory gecko can also run off the ledge at full speed for this pendulumlike flip, known as rapid reversal, with The hooked toenail swings itself completely all over the place to land firmly on the underside of the platform. The researchers then contacted the integrated biologist Ardian Jusufi who was studying the gecko in the tropical rainforest of Singapore, to see if the lizard squats in the same way in the wild.

We don't know if this is an act that really uses the essence to escape the enemy, all said. To his surprise, he found that chasing a broken nest of fern leaves at the end of the gecko also disappeared. Using high-speed video, he found that geckos are used for rapid reversal, just like watching in the laboratory;

Obviously, animals can grab their claws & mdash edges; sometimes only one leg, in the case of 蟑螂 & mdash and retain 75% of the working energy, because they are placed underneath it. They experienced a gravity of about three to five times the flip, similar to the bottom of the human bungee jump, the researchers said, Jean-Michelle Mongeau at the University of California at Berkeley.

These findings not only explain why tiny animal pests, we sometimes chase seems to disappear, but help develop robots that can maneuver. The researchers modified the six-legged style of DASH— the dynamic autonomous 趴 six feet & mdash; by hooking the hook to its hind legs. After they glued the Velcro loop near the window sill, they found that DASH could replicate the acrobatic moves.

U0026; The flip cover shows how we can make small robots more flexible and operability. Finally, if we want to search and rescue robots to help earthquakes, tornadoes or first responders left behind by blasts, or have greater ability to detect chemical, biological or nuclear hazards more quickly, we must Create more flexible robotic mobility and;

After the squats and geckos turn over the window sill, they can continue to run upside down on the surface. The robot may be able to do this, and at the same time, all.

The scientists detailed their findings online in Plos One on June 6.
