Reinforcement learning framework achieves precise excavator control with minimal training

Researchers have developed a novel online model-based reinforcement learning framework designed for precise and high-speed control of hydraulic excavators. This system learns a probabilistic dynamics ensemble model directly from hardware interaction, prioritizing path accuracy with a precision-gated contouring objective. In simulations and real-world tests on a Menzi Muck M445 excavator, the framework demonstrated superior sample efficiency, achieving comparable tracking accuracy to controllers trained for significantly longer periods after only 20 minutes of interaction.
