PROMO: Preference-conditioned Multi-Objective Reinforcement Learning for Quadrupedal Robots
PROMO introduces Preference-Conditioned Multi-Objective Reinforcement Learning (MORL) for quadrupedal robots. It allows a single policy to adapt its behavior dynamically based on operator preferences—like prioritizing tracking, stability, or efficiency—at runtime. This enables robots to trade off locomotion objectives without needing separate controllers or retraining.
