NMPC-Augmented Visual Navigation and Safe Learning Control for Large-Scale Mobile Robots
Mehdi Heydari Shahna, Pauli Mustalahti, Jouni Mattila
A large-scale mobile robot (LSMR) is a high-order multibody system that often operates on loose, unconsolidated terrain, which reduces traction. This paper presents a comprehensive…
Vision-based Goal-Reaching Control for Mobile Robots Using a Hierarchical Learning Framework
Mehdi Heydari Shahna, Pauli Mustalahti, Jouni Mattila
Reinforcement learning (RL) has strong potential in robotics, but exploration-based training complicates safe deployment on large-scale robots. For such applications, this paper pr…
