Mobile Robot Path Planning in Dynamic Environments through Globally Guided Reinforcement Learning

1 code implementation11 May 2020 Binyu Wang, Zhe Liu, Qing-Biao Li, Amanda Prorok

Path planning for mobile robots in large dynamic environments is a challenging problem, as the robots are required to efficiently reach their given goals while simultaneously avoiding potential conflicts with other robots or dynamic objects.
