Dead Matter, Living Machines: Repurposing Crustaceans' Abdomen Exoskeleton for Bio-Hybrid Robots.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bio-hybrid robots utilize living organisms for robot design, however, their use of living bodies makes maintenance, control, and fabrication of robot challenging. As an alternative, exoskeletons stand out for retaining mobility after the organism's death, making them an accessible candidate. In particular, crustacean exoskeletons, often discarded as food waste, provide both structural strength and flexibility from their segmented rigid shell. By repurposing dead animals' part from bio-waste, a sustainable cyclic design process is proposed in which materials can be recycled and adapted for new tasks after a robot's lifespan. In this paper, a bio-hybrid robot design using the langoustine abdominal exoskeleton as a bending actuator is introduced. Through integration with synthetic components, augmented exoskeletons can generate diverse, fast, and robust motions with extended operational lifetimes. Three robotic applications are demonstrated using a 3 g exoskeleton capable of supporting a 680 g payload: a manipulator handling objects up to 500 g, fingers that grasp various objects and bend at speeds up to 8 Hz, and a swimming robot at speeds up to 11 cm s
