BigDog:世界上最先进的四足机器“大狗”


看了上边的视频,你大概会和我一样感慨:这个家伙走起来太像动物了。它的名字叫BigDog,长1米,高0.7米,重75公斤,由波士顿动力(Boston Dynamics)制造。试验中,大狗每小时可以走4英里(约6.4公里),爬坡最高到35度,可以穿过碎石,负重340磅(约154公斤)。

大狗由一台汽油发动机提供动力,靠液压驱动系统驱动。它的腿是铰链式的,还有很多协调装置,可以吸收震动的能量。大狗身上有一台电脑和很多传感器,帮助它控制平衡、转向、定位等等。研究人员希望大狗能够到达动物和人类能够到达的所有地方。

The Most Advanced Quadruped Robot on Earth

BigDog is the alpha male of the Boston Dynamics family of robots. It is a quadruped robot that walks, runs, and climbs on rough terrain and carries heavy loads. BigDog is powered by a gasoline engine that drives a hydraulic actuation system. BigDog’s legs are articulated like an animal’s, and have compliant elements that absorb shock and recycle energy from one step to the next.  Read more.
