Miniature shape-shifting metal robot can melt its way out of tight spaces and reform


Still Waters

Recommended Posts

A miniature, shape-shifting robot can liquefy itself and reform, allowing it to complete tasks in hard-to-access places and even escape cages. It could eventually be used as a hands-free soldering machine or a tool for extracting swallowed toxic items.

Robots that are soft and malleable enough to work in narrow, delicate spaces like those in the human body already exist, but they can’t make themselves sturdier and stronger when under pressure or when they must carry something heavier than themselves. Carmel Majidi at Carnegie Mellon University in Pennsylvania and his colleagues created a robot that can not only shape-shift but also become stronger or weaker by alternating between being a liquid and a solid.

  • The title was changed to Miniature shape-shifting metal robot can melt its way out of tight spaces and reform
 

That sounds like a replicant from Star gate or something else from Star Trek.    Not something we should be playing with.

Not seen any of those programs, but we just know that, we will mess around with something else that will come back and bite us in the ****...

The one example looks like a lego minifig stop motion animated.

After it morphes through the bars  it leaves some of its body sticking to those bars. If it does that like 20 times, nothing will be left of its body.

Completely misleading. It does not "reform" into a specific shape. It's not a robot by any stretch, it's a dumb lump of mixed metals that melts or moves depending on completely external things like temperature and magnets. Article says they had to "dribble it back into a mold" to regain the legoman shape, it didn't reform by itself like you are led to believe by the video.

T-1000 it definitely isn't. It's basically just magnetic low-temp solder.

Cool little video. Probably could be repeated by many college engineering students with gallium and iron filings.

Of course this is just the beggining, I can imagine in the distant future criminals using this for there criminal activities

So a cheap stop-action video of a robot shape moving awkwardly, 'melting' then supposedly reshaping itself (not really) is supposed to be impressive?

I am not impressed in the least.

I'm sure some guy in the Pentagon is eyeballing this right now. The military seems to be a technology development engine in many cases.
