Bioinspired cross-medium wall-climbing robot with high-performance adhesion and contact adaptability.
Article in Science advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Wall-climbing robots (WCRs) using numerous attachment/grasping mechanisms replace humans in executing repetitive or challenging tasks in space-confined, high-risk, or radioactive environments, garnering substantial research interest. Nevertheless, their application remains limited to environment- and surface-specific scenarios. To this end, we present a contact-adaptable, peeling-resistant, and cross-medium WCR integrated with gecko- and octopus-inspired self-adaptive rigid-soft hybrid tracks. The hollow mushroom-shaped adhesive microstructures (HMSAMSs) on the robot tracks simultaneously couple the adhesive structural morphologies of gecko and octopus as well as inherit their functions. These microstructures demonstrate superior normal and tangential adhesion forces and adhesion-to-preload ratios in dry and underwater environments, endowing the WCR with stable cross-medium performance. Furthermore, we construct discrete HMSAMS patches and rigid-soft components in robot track, respectively mimicking biological adhesion's mechanical decoupling and bone-muscle functions, which effectively prevent interface crack propagation, improve peeling threshold, and enhance contact adaptability. The WCR with aforementioned advantages substantially adapts to diverse material surfaces in complex multimedia environments, accelerating its universal application.
