Crash Crash Into Wall
Scientists found that the tough exteriors of cockroaches help them keep moving without losing much momentum when they bump into things. Credit Journal of the Royal Society “Their bodies are doing the computing, not their brains or complex sensors,” said Kaushik Jayaram, a biologist at Harvard University and lead author of the study, which was.

Cars crash into this military surplus shop in Norfolk so often the owners switched a glass wall to brick. Pou Pc Download Torrent. More Crash Crash Into Wall videos. A crazed Brooklyn driver rammed into a cop, then drove more than three miles before crashing into a brick wall as police gave chase early Saturday, cops.
Ellsbury crashed into the center-field wall after snaring Alcides Escobar's barreled drive, slamming his head and right arm against the padded surface.
Using high-speed videography, the researchers recorded 18 male American cockroaches repeatedly running across an acrylic track with only one climbable wall (other walls were coated with petroleum jelly). When they viewed the tapes in slow motion, the researchers were surprised to discover that 80 percent of the time, the insects were simply crashing headfirst into the wall at top speed before making the transition. Other times, they were angling their head upward and using their legs to slow down before reaching the wall. It turns out the cautious approach wasn’t necessary.
The roaches that ran headlong into the wall could make the upward shift just as quickly — in about 75 milliseconds — the researchers found. Apparently, the roaches preferred to run full speed knowing their exoskeleton could take the hit. Free Download Laura Marling Alas Rapidshare Programs And Features. To be sure the roaches were relying on their bodies and not their wits, the researchers ran similar tests with a tiny, cockroach-inspired robot that had no sensors or feedback mechanisms. The results were similar, appearing to confirm Dr. Jayaram’s conclusions.
The findings could prove helpful to engineers as robots become smaller, softer and lighter, Dr. Jayaram believes. “There is an increasing trend to make robots smarter and more capable, so that they can operate effectively indoors or within cluttered natural environments,” he said. If the current study is right, “small robots can be built with simple, robust, smart bodies to safely bump into obstacles instead of using complex and expensive sensing and control systems,” he said.
