Deep Reinforcement Learning for Coordinated Payload Transport in Biped-Wheeled Robots

D. Mehta, A. Joglekar, V. Krovi

IEEE International Conference on Robotics and Automation (ICRA), pp. 14992–14998

A single deep reinforcement learning agent controls two biped-wheeled robots carrying a shared payload, trained with massively parallel simulation in Isaac Lab and transferred to hardware zero-shot within a 0.5 m error range.

Agile Off-Road Terrain Traversal of an Ackermann Steered Platform using Deep Reinforcement Learning

D. Mehta, A. Salvi, V. Krovi

IFAC-PapersOnLine (Modeling, Estimation and Control Conference), Vol. 59(3), pp. 79–84

Learning-based goal-to-goal navigation with a point stabilization task for a mid-scale off-road platform, with reward shaping tuned for stability and a custom off-road simulation environment. 86% success rate at reaching the desired goal.

Rough Terrain Path Tracking of an Ackermann Steered Platform using Hybrid Deep Reinforcement Learning

D. Mehta, A. Salvi, V. Krovi

IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), pp. 685–690

A model-based controller combined with a deep reinforcement learning policy for path tracking across diverse terrains, with rough-terrain assets authored in Blender and exported to OpenUSD. 98.5% precision on unseen real-world tracks.

Actively Articulated Wheeled Architectures for Autonomous Ground Vehicles – Opportunities and Challenges

D. Mehta, K. C. Kosaraju, V. Krovi

SAE Technical Paper 2023-01-0109

A survey of actively articulated wheeled architectures for autonomous ground vehicles: where the added mechanical degrees of freedom buy real capability off-road, and what they cost in control complexity. This review framed the direction of my dissertation work.

Vibration Control in Meta-Structures Using Reinforcement Learning

D. Mehta, S. Malladi

Conference Proceedings of the Society for Experimental Mechanics Series, Springer

Reinforcement learning applied to active vibration control in meta-structures — my first published use of RL, from before the robotics work, and where the interest in learned control started.
