Ground Vehicle Navigation through Traversability Analysis of Outdoor Environments
… la cosiddetta analisi di traversabilità (traversability analysis). Questa può essere vista come una stima della difficoltà incontrata da uno specifico veicolo di terra, caratterizzato quindi dalle sue proprie caratteristiche di locomozione, di attraversare una certa area, a sua volta …

Terrain parameter estimation and traversability assessment for mobile robots
… mobility on rough-terrain. A method to estimate traversability of a rover on deformable terrain using on-board sensors is presented. Simulation and experimental results show that the proposed methods can accurately and efficiently estimate traversability of deformable terrain.

Traversability Estimation Techniques for Improved Navigation of Tracked Mobile Robots
The focus of this dissertation is to improve autonomous navigation in unstructured terrain conditions, with specific application to unmanned casualty extraction in disaster scenarios. Robotic systems are being widely employed for search and rescue applications, especially in disaster scenarios. But …

Learning-Based Complex Terrain Navigation Under Uncertainty
… to learn uncertainty-aware, physics-informed traversability models and achieve risk-aware navigation in both indistribution and out-of-distribution terrain. First, the proposed method efficiently quantifies both aleatoric and epistemic uncertainty by learning discrete traversability …

Terrain and Adversary-Aware Autonomous Robot Navigation
… navigation by learning terrain affordances: traversability (moving quickly) and concealment (staying hidden from an adversary) using the Preference-based Inverse Reward Learning (PbIRL) methodology. The PbIRL methodology reduces the barrier of generating initial demonstration data to learn …

A framework for proving the computational intractability of motion planning problems
… parts of the environment whose state and traversability can change only in response to traversals of the agent within the gadget. The model includes variants for 0-player, 1-player, 2-player, and team imperfect information games. This thesis considers various classes of gadgets and give …

Perturbations and symmetry in gravitational theories : wormholes, wave dynamics, and quantum effects in rotating spacetimes.
… asymptotically Anti–de Sitter (AdS) extension. Traversability, stability, and energy-condition violations are examined, emphasizing how effective geometric contributions support wormhole solutions without explicit exotic matter. Scalar perturbations serve as probes, reducing dynamics to a …
