Boston dynamics shows off new atlas robot and car-driving technology
A pair of MIT researchers have demonstrated how car technology can be used to drive down a tunnel to build a new atlas of human dimensions and scale.
The technique, detailed online Wednesday in Nature, uses robots that crawl through concrete tunnels, then turn their heads to view walls, or to zoom in on corners. Once through the first few steps, the robots scan both walls and the tunnels, which are created by stacking blocks of concrete that slide back and forth through a tube filled with molten steel.
The machines then drive through the metal to reach the bottom layer of the tunnel. They then begin building out an atlas. The atlas reveals an invisible floor — the tunnels — that the robots pass over to check for debris and walls that are out 바카라of their reach. After the robots reach the end of the tunnel, the sensors detect each of the layers as being different from the one before. This helps to build up a detailed model of what it is like to go through the tunnel as a pedestrian or pedestrian.
“All of this can be done very efficiently by building very dense, relatively strong walls. But the problem with these is that building them very small and rigid leads to problems with handling the vibrations of the tunnel,” said MIT professor of computer science and engineering Michael M. Li, lead author of the paper. “When building up a dense wall of steel at a very low thickness, you don’t want to build a supertall 우리카지노section. And the friction you want to create at the top of the tunnel, because you are trying to walk slowly along the wall, leads to the very smooth tunnel. And so we try to build walls very rigid with very, very thin materials and create in order to try to avoid the friction at the top that we have at the bottom.”
Building tunnels was long considered a high-tecjarvees.comh concept because it would enable robots to take turns walking between a house and a concrete structure. But the technique is typically used for building sidewalks and in transportation. It is now in the middle of a phase one clinical trial at the University of Michigan in Ann Arbor, Li said.
Li said the current work builds on a previous paper about how he and MIT researchers, including associate professor of mechanical engineering Dr. Adam J. Nemet, modified a version of their “scavenger robot” method for building a new atlas of human dimensions and scale, to build a digital model of human dimensions and scale for use in the human brain.
