[项目] 重磅机器人搜集 |
先来个NASA的机器人。。。做的感觉挺不错的! 近日,美国宇航局(NASA)刚刚揭开了名为Valkyrie的“超级英雄机器人”的神秘面纱。Valkyrie其名来源于北欧神话中奥丁神的婢女,开发于美国约翰逊航天中心,身高1.89米、重124.7公斤,是DARPA发起的“机器人挑战赛”的设计作品之一。它的名字似乎暗示了它是一名“女性”。 Valkyrie的胸前亮着一个类似钢铁侠的指示灯,而腰部和关节也有着不错的自由度。至于它的动力来源,则是存储于背包之中,据悉动力大约能支撑1个小时。Valkyrie配备了声纳和激光雷达,头部、手部、腹部和腿部也都有传感器。 此外,腿部的摄像头也能够帮助机器人从多个角度进行环境观察。Valkyrie能够不受限制地四处走动,拿起并操作物体。美国航空航天局认为,Valkyrie将把探索太空作为它的使命之一,比如执行火星殖民等任务。 |

Festo, a multinational robotics firm based in Germany, has made some of the most amazing biologically inspired robots out there. In one of our previous posts, "Festo's Extraordinary Robots That Mimic Biology I", you have seen air-penguins and mechanical elephant-arms but these are just few of Festo creations. In these videos, the air-ray, the bionic air-fish, the aqua-jelly, and more are shown. Festo is one of the world leaders in automation, with millions of parts installed in factories all over the globe. Their animal inspired robots are created by the efforts of their Bionic Learning Network. This collection of research groups from academia and industry is part advanced research initiative, part education organization. Festo is a German industrial control and automation company based in Esslingen,Germany. Festo is an engineering driven company that sells pneumatic and electric actuators primarily to the automation industry. |

本帖最后由 swanglei 于 2015-1-4 15:05 编辑 As much as we enjoyed all of the robots performing the ETH Zurich Autonomous Systems Lab’s video, one robot in particular stood out because it didn’t look familiar. You may have spotted it too, at about 1:30: a robot with four orthogonal fins called Sepios. We did some hardcore journalistic research (consisting primarily of a Google search) and found a website on it, along with a very cool video of the robot swimming in the ocean. The official Sepios swimout was in May of this (not much longer this, but still this) year. It’s a student project from ETH Zurich inspired by the noble cuttlefish, which is a friendly sort of cephalopod that propels itself with a pair of undulating fins. Cuttlefish are highly maneuverable little critters, but Sepios is an upgrade, with four independently controllable fins that allow it to rotate on any axis and translate in any direction. It’s sort of like combining a cuttlefish with two knifefish, one of which is upside-down. If you’re not familiar, with a knifefish, here’s a robot from Northwestern University that was inspired by one: Rather than running Sepios’ fins on shafts that cause them to undulate at a fixed frequency and amplitude, each ray of each fin is controlled with its own servo and can move over a range of 270 degrees. That’s 36 servos total, and the completed robot only takes about 4,600 more parts to put together. When it’s in one piece and behaving, Sepios has a top speed of 1.8 km/hr, a maximum depth of 10 meters, and a battery life of an hour and a half, which is easily enough time for an ocean expedition: Sepios has no trouble moving through dense patches of seagrass, even in surge, which would be a tangled nightmare for any underwater vehicle relying on propulsion systems that produce thrust by spinning. It also generates a minimal amount of turbulence, and the ETH team says that these kinds of qualities might make it ideal for observing marine life. The website suggests that future work might include outfitting Sepios with sensors to allow it to traverse an obstacle course, but to be really useful, we're hoping that Sepios acquires a tentacle (or eight). |
