Quadrotor Guidance for Tasks along Elliptical Boundary
Ravi Khandelwal, Ashwini Ratnoo
This paper presents a guidance method that enables a quadrotor uncrewed aerial vehicle to perform inspection tasks along an elliptical boundary enclosing a structure of interest. T…
Loiter UAV Reinsertion Guidance for Fixed-wing UAV Corridors
Pradeep J, Kedarisetty Siddhardha, Ashwini Ratnoo
This paper considers fixed-wing unmanned aerial vehicle (UAV) corridors comprising a main lane, a circular loiter lane for managing traffic congestion, and transit lanes connecting…
Slot-hopping Enabled Loiter Guidance and Automation for Fixed-wing UAV Corridors
Pradeep J, Siddhardha Kedarisetty, Ashwini Ratnoo
This paper addresses the problem of traffic congestion management in fixed-wing unmanned aerial vehicle (UAV) corridors by further developing a recently introduced loiter-lane fram…
Multi-UAV Path Following using Vector-Field Guidance
Gautam Kumar, Amit Shivam, Ashwini Ratnoo
This paper presents a decentralized, collision-free framework for path following guidance of multiple uncrewed aerial vehicles (UAVs), while maintaining uniform spacing along a ref…
Latent Space Reinforcement Learning for Multi-Robot Exploration
Sriram Rajasekar, Ashwini Ratnoo
Autonomous mapping of unknown environments is a critical challenge, particularly in scenarios where time is limited. Multi-agent systems can enhance efficiency through collaboratio…
Closing Speed Computation using Stereo Camera and Applications in Unsignalized T-Intersection
Gautam Kumar, Ashwini Ratnoo
This letter presents a conflict resolution strategy for an autonomous vehicle mounted with a stereo camera approaching an unsignalized T-intersection. A mathematical model for unce…
Quadrotor Guidance for Window Traversal: A Bearings-Only Approach
Midhun E K, Ashwini Ratnoo
This paper focuses on developing a bearings-only measurement-based three-dimensional window traversal guidance method for quadrotor Uninhabitated Aerial Vehicles (UAVs). The desire…
Cooperative Target Capture using Voronoi Region Shaping
Gautam Kumar, Ashwini Ratnoo
This paper discusses a cooperative strategy for capturing a target using multiple pursuers in a planar scenario. Given an initial position distribution of pursuers, the Voronoi Dia…
A Novel Convex Layers Strategy for Circular Formation in Multi-Agent Systems
Gautam Kumar, Ashwini Ratnoo
This article considers the problem of conflict-free distribution of point-sized agents on a circular periphery encompassing all agents. The two key elements of the proposed policy…
CORRIDRONE: Corridors for Drones, An Adaptive On-Demand Multi-Lane Design and Testbed
Lima Agnel Tony, Ashwini Ratnoo, Debasish Ghose
In this article, a novel drone skyway framework called CORRIDRONE is proposed. As the name suggests, this represents virtual air corridors for point-to-point safe passage of multip…
Multi-vehicle Path Following using Modified Trajectory Shaping Guidance
Ishmaal Erekson, Rajnikant Sharma, Ashwini Ratnoo +1
In this paper, we formulate a virtual target-based path following guidance law aimed towards multi-vehicle path following problem. The guidance law is well suited to precisely foll…
