Universal Navigation Interface: Robot-Free Data for Wheeled Robot Navigation
Sarvesh Prajapati, Ananya Trivedi, Lorena Maria Genua +3
Collecting real-world navigation data for mobile robots typically requires platform-specific teleoperation, making large-scale collection expensive and difficult to scale. We intro…
Accelerating Optimization over Graphs of Convex Sets via Neural Network Approximations
Ananya Trivedi, Sarvesh Prajapati, Mohamed Khalid M Jaffar +3
Motion planning problems such as collision-free navigation and contact-rich manipulation can be naturally formulated as optimization problems that couple discrete decisions with co…
Socially-Aware Autonomous Doorway Traversal and Payload Delivery for Emergency Assistance
Andrew Snowdy, Ananya Trivedi, Sarvesh Prajapati +2
In this work, we focus on the scenario of a robot-assisted emergency evacuation. We consider two capabilities relevant to such a setting. The first is opening doors ahead of the pe…
VLM-Based Advanced Rider Assistance System for Motorcycle Safety
Mohamed Elnoor, Francesca Baldini, Ananya Trivedi +6
Motorcycles face disproportionately high crash risks compared to cars due to limited protection and heightened sensitivity to surface hazards, yet Advanced Rider Assistance Systems…
Adaptive Time Step Flow Matching for Autonomous Driving Motion Planning
Ananya Trivedi, Anjian Li, Mohamed Elnoor +7
Autonomous driving requires reasoning about interactions with surrounding traffic. A prevailing approach is large-scale imitation learning on expert driving datasets, aimed at gene…
Spectral Signature Mapping from RGB Imagery for Terrain-Aware Navigation
Sarvesh Prajapati, Ananya Trivedi, Nathaniel Hanson +2
Successful navigation in outdoor environments requires accurate prediction of the physical interactions between the robot and the terrain. Many prior methods rely on geometric or s…
Chance-Constrained Convex MPC for Robust Quadruped Locomotion Under Parametric and Additive Uncertainties
Ananya Trivedi, Sarvesh Prajapati, Mark Zolotas +2
Recent advances in quadrupedal locomotion have focused on improving stability and performance across diverse environments. However, existing methods often lack adequate safety anal…
Data-Driven Sampling Based Stochastic MPC for Skid-Steer Mobile Robot Navigation
Ananya Trivedi, Sarvesh Prajapati, Anway Shirgaonkar +2
Traditional approaches to motion modeling for skid-steer robots struggle with capturing nonlinear tire-terrain dynamics, especially during high-speed maneuvers. In this paper, we t…
Predictive Mapping of Spectral Signatures from RGB Imagery for Off-Road Terrain Analysis
Sarvesh Prajapati, Ananya Trivedi, Bruce Maxwell +1
Accurate identification of complex terrain characteristics, such as soil composition and coefficient of friction, is essential for model-based planning and control of mobile robots…
A Probabilistic Motion Model for Skid-Steer Wheeled Mobile Robot Navigation on Off-Road Terrains
Ananya Trivedi, Mark Zolotas, Adeeb Abbas +3
Skid-Steer Wheeled Mobile Robots (SSWMRs) are increasingly being used for off-road autonomy applications. When turning at high speeds, these robots tend to undergo significant skid…
