GrASPE: Graph based Multimodal Fusion for Robot Navigation in Unstructured Outdoor Environments
Kasun Weerakoon, Adarsh Jagan Sathyamoorthy, Jing Liang +3
We present a novel trajectory traversability estimation and planning algorithm for robot navigation in complex outdoor environments. We incorporate multimodal sensory inputs from a…
HTRON:Efficient Outdoor Navigation with Sparse Rewards via Heavy Tailed Adaptive Reinforce Algorithm
Kasun Weerakoon, Souradip Chakraborty, Nare Karapetyan +3
We present a novel approach to improve the performance of deep reinforcement learning (DRL) based outdoor robot navigation systems. Most, existing DRL methods are based on carefull…
Sim-to-Real Strategy for Spatially Aware Robot Navigation in Uneven Outdoor Environments
Kasun Weerakoon, Adarsh Jagan Sathyamoorthy, Dinesh Manocha
Deep Reinforcement Learning (DRL) is hugely successful due to the availability of realistic simulated environments. However, performance degradation during simulation to real-world…
AdaptiveON: Adaptive Outdoor Local Navigation Method For Stable and Reliable Actions
Jing Liang, Kasun Weerakoon, Tianrui Guan +2
We present a novel outdoor navigation algorithm to generate stable and efficient actions to navigate a robot to reach a goal. We use a multi-stage training pipeline and show that o…
TerraPN: Unstructured Terrain Navigation using Online Self-Supervised Learning
Adarsh Jagan Sathyamoorthy, Kasun Weerakoon, Tianrui Guan +2
We present TerraPN, a novel method that learns the surface properties (traction, bumpiness, deformability, etc.) of complex outdoor terrains directly from robot-terrain interaction…
