Defensive Escort Teams via Multi-Agent Deep Reinforcement Learning

no code implementations9 Oct 2019 Arpit Garg, Yazied A. Hasan, Adam Yañez, Lydia Tapia

When compared to a state-of-art algorithm for obstacle avoidance, our solution with a single escort increases navigation success up to 31%.

RL-RRT: Kinodynamic Motion Planning via Learning Reachability Estimators from RL Policies

no code implementations10 Jul 2019 Hao-Tien Lewis Chiang, Jasmine Hsu, Marek Fiser, Lydia Tapia, Aleksandra Faust

Through the combination of sampling-based planning, a Rapidly Exploring Randomized Tree (RRT) and an efficient kinodynamic motion planner through machine learning, we propose an efficient solution to long-range planning for kinodynamic motion planning.

Deep Neural Networks for Swept Volume Prediction Between Configurations

no code implementations29 May 2018 Hao-Tien Lewis Chiang, Aleksandra Faust, Lydia Tapia

Swept Volume (SV), the volume displaced by an object when it is moving along a trajectory, is considered a useful metric for motion planning.

PRM-RL: Long-range Robotic Navigation Tasks by Combining Reinforcement Learning and Sampling-based Planning

no code implementations11 Oct 2017 Aleksandra Faust, Oscar Ramirez, Marek Fiser, Kenneth Oslund, Anthony Francis, James Davidson, Lydia Tapia

The RL agents learn short-range, point-to-point navigation policies that capture robot dynamics and task constraints without knowledge of the large-scale topology.
