    Catalyst: Robot Biomimicry

    Uploaded on Jan 23, 2011

    Scientists at the University of California Berkeley are convinced they are offering a breakthrough in robot design. Their study of living organisms has offered insights which they've adapted to the world's first robotic cockroach, or, Robo Roach. Graham discovers how the ingenuity of nature may help develop technology that could finally bring about the robot revolution. Full info:

    This Robo-Roach might someday save lives

    Published on Feb 8, 2016

    Researchers at UC Berkeley have developed a robotic cockroach capable of squeezing through tight spaces. Someday swarms of robo-roaches could be sent into disaster areas like earthquake rubble to search for survivors.

    Cockroach robots to the rescue!

    Published on Feb 8, 2016

    Our fear and disgust that cockroaches can quickly squeeze through the tiniest cracks are well justified, say University of California, Berkeley scientists.

    Not only can they squish themselves to get into one-tenth-of-an-inch crevices, but once inside they can run at high speed even when flattened in half.

    These are just a couple of the creepy findings from a UC Berkeley study of how American cockroaches (Periplaneta americana) penetrate the tightest joints and seams in less than a second.

    What the researchers found has inspired a robot that can rapidly squeeze through cracks — a new capability for search-and-rescue in rubble resulting from tornados, earthquakes and explosions.

    “What’s impressive about these cockroaches is that they can run as fast through a quarter-inch gap as a half-inch gap, by reorienting their legs completely out to the side,” said study leader Kaushik Jayaram, who recently obtained his Ph.D. from UC Berkeley and is now a postdoctoral fellow at Harvard University. “They’re about half an inch tall when they run freely, but can squish their bodies to one-tenth of an inch — the height of two stacked pennies.”

    Roaches traversing crevices, Jayaram found, can withstand forces 900 times their body weight without injury.

    Using the roach technique as inspiration, Jayaram designed a simple and cheap palm-sized robot that can splay its legs outward when squashed, then capped it with a plastic shield similar to the tough, smooth wings covering the back of a cockroach. Called CRAM, for compressible robot with articulated mechanisms, it was able to squeeze into and run through crevices half its height.

    “In the event of an earthquake, first responders need to know if an area of rubble is stable and safe, but the challenge is, most robots can’t get into rubble,” said Robert Full, a professor of integrative biology at UC Berkeley. “But if there are lots of cracks and vents and conduits, you can imagine just throwing a swarm of these robots in to locate survivors and safe entry points for first responders.”
    Jayaram built the model robot using an origami-like manufacturing technique, now available as an inexpensive kit made by Dash Robotics — a commercial spin-off from previous robotic work at UC Berkeley. Now, more robust versions will be needed for real-world testing.

    “This is only a prototype, but it shows the feasibility of a new direction using what we think are the most effective models for soft robots, that is, animals with exoskeletons,” Full said. “Insects are the most successful animals on earth. Because they intrude nearly everywhere, we should look to them for inspiration as to how to make a robot that can do the same.”

    Jayaram and Full will publish their findings this week in the early online edition of the journal Proceedings of the National Academy of Sciences.

    Over the past three decades, Full and students in his Poly-PEDAL lab have studied how animals walk, run, jump, glide, crawl and slither to understand the basic biomechanical principles that underlie locomotion, and that can be used to design better robots. Their findings have inspired robots with legs like those of cockroaches and crabs as well as sticky feet like those of geckos. Full, 25 years ago, discovered that American cockroaches can run on two legs – a feat certified by the Guinness Book of World Records – and can achieve a speed of nearly 5 feet per second, or 50 times their body length per second.

    Using a high-speed camera, Jayaram filmed roaches running at nearly full speed between plates spaced a quarter-inch apart, less than the thinnest part of a roach’s body. By narrowing the slits, he found that they could slip through slits of one-tenth of an inch if highly motivated.

    While squashed, they cannot properly use their feet, so they use the sensory spines on their tibia to push against the floor to move forward.

    “They have to use different body parts to move in these spaces, because their legs and feet are not oriented to work properly,” Jayaram said. “But they are still capable of generating the large forces necessary for locomotion, which blew my mind.”

    This cockroach robot won't be squashed

    Published on Feb 10, 2016

    The cockroach is probably your least favorite insect...but it inspires a robot that will do great things. This robot created by engineers at The University of California, Berkeley can squeeze down through very tight spaces, but still keep its locomotion!

    What other animal should inspire a helpful robot?

    Robotic Cockroach

    Cockroaches move so well through small spaces that they make good models for robots to find survivors in collapsed buildings.
