Chinese scientists built an 'Iron Maninspired'

robot with jet-powered feet

that can do a SPLIT to prevent it from

falling as it crosses wide gaps

●The robot, called Jet-HR1, has two small jet engines that are attached to its feet

●The jet engines only weigh 232 grams, but they can produce up to 2kg of thrust

●Jet-HR1 was able to step over a 37cm-wide gap that represented 80% of its leg

 

Chinese scientists have developed a robot that could be straight out of the Iron Man movies.

The two-legged bot is outfitted with small jet engines that are attached to its feet.

Robotics engineers at Guangdong University of Tech's School of Automation in China strapped two duct fans to the robot's feet which allow it to cross wider distances than it would have been able to previously.

It alsosolves a major problem commonly experienced by robot developers.

Most bipedal robots are only capable of making static movements like walking forward in short, controlled steps.

When walking across a challenging terrain, or facing some kind of obstacle that they must step over, things become a bit more challenging and, at times, dangerous.

That's why many robots have been known to fall over when charged with more complex tasks or movements.

Humans are able to twist and contort their bodies in order to keep themselves from falling, while robots don't possess that capability.

But the Chinese robot, called Jet-HR1, isn't likely to fall because the jet engines are able to balance its center of gravity.

   

   

The robot, called Jet-HR1, is outfited with two jet engines that are strapped to its feet.The jets only weigh 232 grams, but they can produce up to 2kg of thrust, according to scientists

 

Jet-HR1 is just 65cm, or roughly two feet, tall and weighs 6.5kg.

Its jet engines only weigh 232 grams, but they can produce up to 2kg of thrust, which is nearly a third of the entire weight of the entire robot, according to IEEE Spectrum.

So while Jet-HR1 is incapable of flying through the air just yet,the engines still pack plenty of power that allow it to complete more tasks at an even quicker pace.

In a video, Jet-HR1 can be seen stepping over a large gap that's 37cm wide.

To get over the gap, the robot had tocomplete a step length that represented 80% of its leg, IEEE noted.

The robot extended a leg first,stretching it all the other side,in a move that almost looks like a split.

Once it's anchored on the other side of the gap, the robot then pushes off with its other leg, which gives it enough momentum to stand up almost completely straight.

In all, it took the robot less than a minute to maneuver the gap, which is much faster than it would have taken previously.

Without the fans, Jet-HR1 would only be able to cross a distance that was 3.5-inches wide, according to Gizmodo.

Assisted by the jet engines, the robot could potentially cross distances that are up to 1.5 feet wide, which is roughly 97% of the robot leg's length.

The researchers believe that the findings could be applied to many robots that face more challenging search and rescue missions.

It could also lead to more futuristic applications, like flying robots powered by jet thrusters--an image that inspired researchers involved in the latest study.

'We were more or less inspired by science fiction,Zhifeng Huang,one of the researchers involved in the study ,told IEEE.

 

   

 A video shows the Jet-HR1 crossing a wide gap between two surfaces. It took the robot less than a minute to maneuver the gap, which is much faster than it would have taken previously

 

'In fact, we considered this idea two years ago, when we noticed the mobility limitation of humanoid robots when going through rubble and debris in an earthquake aftermath scenario'

'...That’s why we think a new method that enables the robot to maintain a quasi-static balance and produces a less significant impact whil it steps over obstacles is necessary‘

'And our idea was utilizing the external force of the jets to maintain the balance of the robot,' he added.

Huang noted that the jet propulsion technique could lead to further advancements in how robots are able to jump, teeter on one leg, perform 3D movements and reduceimpact during 'dynamic motion.'

据英国《每日邮报》网站3月20日报道,大多数双足机器人都只能做静态运动,以小碎步向前行走,如果遇到困难的地形,或是面临某种必须跨越的障碍时,情况就变得有点难办了,有时甚至很危险。这就是为何很多机器人承担较复杂的任务或行动时会摔倒的原因——为了防止摔倒,人类可以扭动或弯曲身体,而机器人却不具备这种能力。

报道称,但是,中国制造的这款Jet-HR1机器人不会摔倒,研发者将两个涵道风扇固定在机器人的脚上,喷气引擎可以平衡它的重心,这样它就能够跨越更大的距离。

报道称,Jet-HR1只有65厘米高,重6.5公斤。它的喷气引擎重量仅为232克,但是却能够产生高达2公斤的推力,几乎相当于整个机器人重量的三分之一。所以,虽然Jet-HR1目前还不能在空中飞越,但是喷气引擎仍然能够产生足够的动力,使它能够以更快的速度完成更多的任务。

在一段视频中,可以看到Jet-HR1能够跨越37厘米宽的缝隙。要跨越这么大的缝隙,机器人必须迈出相当于腿部长度80%的步伐,Jet-HR1总共用了不到一分钟就跨过了缝隙,比以前的机器人快了很多。但如果不装风扇,Jet-HR1只能跨越8.9厘米的宽度。有了喷气引擎助力,机器人可以跨越宽度达45.7厘米的距离,大约相当于机器人腿长的97%。

研究人员认为,研究结果可应用于更多面临挑战情形的机器人,比如搜救任务机器人。它还能带来更多未来的应用,比如飞行机器人。

研究人员说:“我们或多或少受了科幻小说的启发。”“事实上,我们两年前就想到这个办法了……我们的想法是利用喷气引擎的外部力量保持机器人的平衡。”研究人员指出,喷气助推技术可在机器人的跨越能力方面推动更大进步。(编译/郑国仪)(来源:参考消息)
