Towards Spatial Perception for Heterogeneous Robot Collaboration in Subterranean Mining Environments
Mario Alberto Valdes Saucedo, Akash Patel, Christoforos Kanellakis +1
The autonomous extraction of deep mineral deposits in abandoned underground mines is fundamentally a multi-agent integration problem. No single platform simultaneously offers the m…
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…
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…
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…
STAGE: Scalable and Traversability-Aware Graph based Exploration Planner for Dynamically Varying Environments
Akash Patel, Mario A V Saucedo, Christoforos Kanellakis +1
In this article, we propose a novel navigation framework that leverages a two layered graph representation of the environment for efficient large-scale exploration, while it integr…
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…
Event Camera and LiDAR based Human Tracking for Adverse Lighting Conditions in Subterranean Environments
Mario A. V. Saucedo, Akash Patel, Rucha Sawlekar +4
In this article, we propose a novel LiDAR and event camera fusion modality for subterranean (SubT) environments for fast and precise object and human detection in a wide variety of…
Towards Energy Efficient Autonomous Exploration of Mars Lava Tube with a Martian Coaxial Quadrotor
Akash Patel, Samuel Karlsson, Bjorn Lindqvist +3
Mapping and exploration of a Martian terrain with an aerial vehicle has become an emerging research direction, since the successful flight demonstration of the Mars helicopter Inge…
REF: A Rapid Exploration Framework for Deploying Autonomous MAVs in Unknown Environments
Akash Patel, Björn Lindqvist, Christoforos Kanellakis +2
Exploration and mapping of unknown environments is a fundamental task in applications for autonomous robots. In this article, we present a complete framework for deploying MAVs in…
Design and Model Predictive Control of Mars Coaxial Quadrotor
Akash Patel, Avijit Banerjee, Bjorn Lindqvist +2
Mars has been a prime candidate for planetary exploration of the solar system because of the science discoveries that support chances of future habitation on this planet. Martian c…
Multi-Sparse Gaussian Process: Learning based Semi-Parametric Control
Mouhyemen Khan, Akash Patel, Abhijit Chatterjee
A key challenge with controlling complex dynamical systems is to accurately model them. However, this requirement is very hard to satisfy in practice. Data-driven approaches such a…
Online Center of Mass Estimation for a Humanoid Wheeled Inverted Pendulum Robot
Munzir Zafar, Akash Patel, Bogdan Vlahov +3
We present a novel application of robust control and online learning for the balancing of a n Degree of Freedom (DoF), Wheeled Inverted Pendulum (WIP) humanoid robot. Our technique…
