Hysteresis-assisted shape morphing for soft continuum robots.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Conventional robots require more actuators for greater dexterity, increasing design and control complexity. We introduce a hysteresis-assisted shape-morphing (HasMorph) paradigm for soft continuum robots and integrate with tip-everting soft-growing robots. Unlike conventional approaches that avoid hysteresis, HasMorph intentionally exploits friction-induced shape hysteresis, the difference in robot shape during loading and unloading, to enable numerous reversible shape changes using only two sequentially controlled actuators via an inverted zigzag tendon-sheath mechanism. Integrated with tip growth, the robot achieves complex, reversible morphologies and frictionless follow-the-leader navigation. Mechanics and kinematics models reveal how friction and input sequences govern shape evolution and expand the robot's configuration space. Experiments validate dexterous morphing and robust navigation in unstructured environments. HasMorph enables direct, fine-grained actuation of hyperredundant soft bodies with minimal actuation, offering a scalable approach to soft robot design. This paradigm opens avenues for minimally invasive surgical tools and adaptive inspection systems in complex, confined spaces.
