The great tradition of designing robots inspired by the many beautiful forms of locomotion seen in the animal kingdom likely predates robotics itself, arguably stretching all the way back to Michelangelo's time. Standing on the shoulders of such giants is ATRIAS, a series of human-sized bipedal robots that remind us of other two-legged creatures like the ostrich or emu.

ATRIAS is a project of Oregon State University's Dynamic Robotics Laboratory built to research the science of walking and running with the ultimate goal of creating a robot that can make its way over rough terrain while "standing." The ATRIAS design is based around two spring-loaded legs similar to that of a pogo stick, but rather than causing the robot to bounce around, its springy legs act as both a suspension system and storage mechanism for mechanical energy, theoretically making it more agile and efficient.

ATRIAS seems a bit goofy at first. It has no real feet to speak of, just the small end points of its legs, and it "stands" by basically walking in place, so it's almost always moving.

The team behind ATRIAS compares it to a sports car, in that all its mechanisms are designed and tuned to work together for maximum performance. But like many fast cars, the creators also concede that the robot isn't easy to control. Because it is designed to be as close to a simple spring-mass system as possible (ATRIAS stands for "Assume The Robot Is A Sphere), the mathematics typically used to control robot walking don't work for it, requiring researchers to invent new controllers as they go.

The goal of ATRIAS isn't just to create a walking robot, but to create one that is better at reacting and recovering from unexpected obstacles. As you can see from the video below, ATRIAS holds its own against a barrage of dodge balls, failing only when its emergency shut-off button is accidentally struck by a ball. With a little more engineering, it seems easy to imagine ATRIAS making one heck of a goalie some day.

In addition to the Oregon State lab, prototypes are also in use in research at the University of Michigan and Carnegie Mellon University in Pennsylvania.

For a closer look at ATRIAS, the team behind it will be demonstrating at the DARPA Robotics Challenge in southern California in June.

灵感来自于许多美丽的运动形式出现在动物王国中设计机器人的伟大的传统很可能早于机器人本身,可以说是一路绵延回米开朗基罗的时间。站在这样的巨人的肩膀上是ATRIAS,一系列人大小的两足机器人是提醒其他两足动物,如鸵鸟和鸸鹋我们。

ATRIAS是俄勒冈州立大学的动态机器人学重点实验室项目建立研究走路的使用和创建一个机器人,可以作出自己的方式在崎岖的地形,而最终目标运行的科学“屹立不倒。”所述ATRIAS设计是基于围绕两个弹簧加载的腿相似的弹簧单高跷的,但不是使所述机器人反弹各处,其弹性腿同时充当一个悬挂系统和存储机构,用于机械能,理论上使之更敏捷高效。


ATRIAS似乎有点傻傻的在第一。它有没有真正的脚来说话的,它的腿只是小的终点,它“代表”,由基本原地走的,所以它几乎总是感动。


背后ATRIAS团队比较其跑车,在那它的所有机制的设计和调整,以协同工作以获得最佳性能。但是,像许多快速的汽车,创作者也承认,机器人不容易控制。因为它被设计为尽可能接近一个简单的弹簧质量系统地(ATRIAS代表“假设机械手是一个球),数学通常用于控制机器人行走不为它工作,要求研究人员发明新因为他们去控制器。



ATRIAS的目标不仅仅是创建一个行走的机器人,而是创造一个是在反应和意想不到的障碍恢复好。你可以从下面的视频中看到,ATRIAS持有它自己对攻势闪避球的,只有失败的时候它的紧急关闭按钮时不慎被球击中。多一点的工程,它似乎很容易想象ATRIAS使守门员之一赫克的一天。


除俄勒冈州的实验室,原型也是在密歇根大学和卡内基·梅隆大学在宾夕法尼亚州研究使用。


要仔细看看ATRIAS,其背后的团队将展示在DARPA机器人挑战赛在加州南部六月
