Longitudinal-Motion-Aware Lateral Control for Autonomous Vehicles: A Robust Nonlinear Control Framework
Sixu Li, Nitesh Kumar, Reyshwanth Ganeshan +3
As autonomous vehicles (AVs) operate in increasingly dynamic traffic conditions, lateral control must be performed while longitudinal speed and acceleration vary. Yet many existing…
Lateral String Stability for Vehicle Platoons
Sixu Li, Swaroop Darbha, Yang Zhou
Connected and automated vehicle (CAV) platooning promises gains in energy efficiency and traffic throughput and, most critically, in safety. These safety benefits hinge on string s…
Privacy-Preserving Decentralized Cooperative Localization with Range-Only Measurements: A Convex Optimization Based Approach
Nitesh Kumar, Reyshwanth Ganeshan, Sixu Li +2
Cooperative localization using range-based measurements is critical for multi-robot systems operating in GPS-denied and unstructured environments. However, traditional cooperative…
Lateral String Stability for Vehicle Platoons: Formulation, Definition, and Analysis
Sixu Li, Swaroop Darbha, Yang Zhou
Platooning of connected and automated vehicles provides significant benefits in terms of energy efficiency, traffic throughput, and, most critically, safety. These safety benefits…
A Novel Model for 3D Motion Planning for a Generalized Dubins Vehicle with Pitch and Yaw Rate Constraints
Deepak Prakash Kumar, Swaroop Darbha, Satyanarayana Gupta Manyam +1
In this paper, we propose a new modeling approach and a fast algorithm for 3D motion planning, applicable for fixed-wing unmanned aerial vehicles. The goal is to construct the shor…
Time-optimal Convexified Reeds-Shepp Paths on a Sphere
Sixu Li, Deepak Prakash Kumar, Swaroop Darbha +1
This article studies the time-optimal path planning problem for a convexified Reeds-Shepp (CRS) vehicle on a unit sphere, capable of both forward and backward motion, with speed bo…
The Persistent Robot Charging Problem for Long-Duration Autonomy
Nitesh Kumar, Jaekyung Jackie Lee, Sivakumar Rathinam +3
This paper introduces a novel formulation aimed at determining the optimal schedule for recharging a fleet of heterogeneous robots, with the primary objective of minimizing res…
Assisted Path Planning for a UGV-UAV Team Through a Stochastic Network
Abhay Singh Bhadoriya, Sivakumar Rathinam, Swaroop Darbha +2
In this article, we consider a multi-agent path planning problem in a stochastic environment. The environment, which can be an urban road network, is represented by a graph where t…
Cooperative Coverage with a Leader and a Wingmate in Communication-Constrained Environments
Sai Krishna Kanth Hari, Sivakumar Rathinam, Swaroop Darbha +1
We consider a mission framework in which two unmanned vehicles (UVs), a leader and a wingmate, are required to provide cooperative coverage of an environment while being within a s…
Assisted Shortest Path Planning for a Convoy through a Repairable Network
Abhay Singh Bhadoriya, Christopher Montez, Sivakumar Rathinam +3
In this article, we consider a multi-agent path planning problem in a partially impeded environment. The impeded environment is represented by a graph with select road segments (ed…
Bounds on Optimal Revisit Times in Persistent Monitoring Missions with a Distinct \& Remote Service Station
Sai Krishna Kanth Hari, Sivakumar Rathinam, Swaroop Darbha +3
Persistent monitoring missions require an up-to-date knowledge of the changing state of the underlying environment. UAVs can be gainfully employed to continually visit a set of tar…
