Among the many many issues that people can’t do (with out some pretty substantial modification) is shifting our physique morphology round on demand. It sounds a little bit excessive to be speaking about issues like self-amputation, and it
is a little bit excessive, however it’s additionally under no circumstances unusual for different animals to do—lizards can disconnect their tails to flee a predator, for instance. And it really works within the different course, too, with animals like ants including to their morphology by connecting to one another to traverse gaps {that a} single ant couldn’t cross alone.
In a brand new paper, roboticists from
The Faboratory at Yale College have given a delicate robotic the power to detach and reattach items of itself, modifying its physique morphology when mandatory. It’s a little bit freaky to observe, however it type of makes me want I might do the identical factor.

These are pretty commonplace soft-bodied silicon robots that use asymmetrically stiff air chambers that inflate and deflate (utilizing a tethered pump and valves) to generate a strolling or crawling movement. What’s new listed here are the joints, which depend on a brand new materials referred to as a bicontinuous thermoplastic foam (BTF) to kind a supportive construction for a sticky polymer that’s stable at room temperature however may be simply melted.
The BTF acts like a sponge to stop the polymer from working out all over when it melts, and means that you may pull two BTF surfaces aside by melting the joint, and stick them collectively once more by reversing the process. The method takes about 10 minutes and the ensuing joint is kind of sturdy. It’s additionally good for a pair hundred dettach/reattach cycles earlier than degrading. It even stands as much as filth and water moderately nicely.

This type of factor has been executed earlier than with mechanical connections and magnets and different issues like that—getting robots to connect to and detach from different robots is a foundational method for modular robotics, in spite of everything. However these methods are inherently inflexible, which is dangerous for delicate robots, whose complete factor is about
not being inflexible. It’s all very preliminary, in fact, as a result of there are many inflexible issues connected to those robots with tubes and wires and stuff. And there’s no autonomy or payloads right here both. That’s not the purpose, although—the purpose is the joint, which (because the researchers level out) is “the primary instantiation of a totally delicate reversible joint” ensuing within the “potential for delicate synthetic methods [that can] form change by way of mass addition and subtraction.”
