NASA’s Nancy Grace Roman Space Telescope team is announcing the official designs for the mission’s three core surveys. These observation programs will investigate some of the most profound mysteries in astrophysics while enabling expansive cosmic exploration that will revolutionize our understanding of the universe.
Scientists have designed a bioinspired soft robot that can jump several times its own body length. Sunny Kumar and colleagues uncovered the mechanisms that enable some parasitic worms to propel themselves towards potential hosts by bending their bodies to create a “kink.” Using this discovery, the authors built a soft cylindrical robot that could form reversible kinks and launch itself from the ground and through a 10-foot-high basketball hoop. These findings could expand the applications of limbless soft robots. Kinks form when an object is bent beyond a certain point and can often be harmful to living organisms. For instance, kinks can lead to blockages in blood vessels and permanent damage in plant stems. However, studies have suggested that some nematodes can harness kinks to leap and ambush hosts. To investigate the underlying mechanisms, Kumar et al. used high-speed imaging to study Steinernema carpocapsae, a nematode that infects insects. They found that, when stimulated with host-related cues, the larval nematode stood up on its tail and contorted its body to form an “α” shape. The stiff cuticle of the larva’s midsection and liquid inside its body facilitated the storage of elastic energy and subsequent spring-latch-like release, generating powerful and extremely fast jumps. Based on these observations, the researchers developed a silicone soft robot with a carbon fiber backbone for stiffness. They conducted a series of experiments and demonstrated that the soft robot could generate enough power through reversible kink formation to jump on sand, onto a car, or over a hurdle. At the same time, the jumper was soft enough to bounce off a balloon without bursting it, highlighting its safety for use around humans. Kumar et al. propose that their approach could inform designs for “limbless robots for controlled jumping, locomotion, and even planetary exploration.”
