SPADE: Towards Scalable Path Planning Architecture on Actionable Multi-Domain 3D Scene Graphs
Vignesh Kottayam Viswanathan, Akash Patel, Mario Alberto Valdes Saucedo +3
In this work, we introduce SPADE, a path planning framework designed for autonomous navigation in dynamic environments using 3D scene graphs. SPADE combines hierarchical path plann…
A Hierarchical Graph-Based Terrain-Aware Autonomous Navigation Approach for Complementary Multimodal Ground-Aerial Exploration
Akash Patel, Mario A. V. Saucedo, Nikolaos Stathoulopoulos +4
Autonomous navigation in unknown environments is a fundamental challenge in robotics, particularly in coordinating ground and aerial robots to maximize exploration efficiency. This…
Leveraging Computation of Expectation Models for Commonsense Affordance Estimation on 3D Scene Graphs
Mario A. V. Saucedo, Nikolaos Stathoulopoulos, Akash Patel +2
This article studies the commonsense object affordance concept for enabling close-to-human task planning and task optimization of embodied robotic agents in urban environments. The…
A Tree-based Next-best-trajectory Method for 3D UAV Exploration
Björn Lindqvist, Akash Patel, Kalle Löfgren +1
This work presents a fully integrated tree-based combined exploration-planning algorithm: Exploration-RRT (ERRT). The algorithm is focused on providing real-time solutions for loca…
Belief Scene Graphs: Expanding Partial Scenes with Objects through Computation of Expectation
Mario A. V. Saucedo, Akash Patel, Akshit Saradagi +2
In this article, we propose the novel concept of Belief Scene Graphs, which are utility-driven extensions of partial 3D scene graphs, that enable efficient high-level task planning…
