From one tree to the canopy: an evolutionary design trajectory for tethered robotics in forest environments.
Article in Frontiers in robotics and AI, 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
Forest robotics has largely evolved along a ground-first and flight-dominant trajectory, treating the canopy as a region to observe or briefly access rather than a habitat to inhabit. In this Perspective, we propose an alternative canopy-first framework in which robots operate through anchoring, suspension, and tension-mediated interaction with the environment. We trace the progression from ground and aerial systems to perching mechanisms, identifying their shared limitation as transient canopy interaction. Tether-based robots instead enable sustained presence by transforming branches into structural supports. Within this context, TreeSpider is presented as an early canopy-innate morphology. We argue that such systems point toward a broader class of structure-innate robotics, where behavior emerges through physical coupling with the environment rather than continuous free-space mobility.
