Researchers have developed a new Dyna-style framework that significantly improves the data efficiency of reinforcement learning (RL) for quadrupedal locomotion. By integrating a learned transition model to generate synthetic data, the method reduces the number of simulation steps required for stable control. Experiments on Unitree Go1 robots showed convergence with 19.64 million simulation steps, a reduction from 27.53 million, and a 12.24% decrease in training time without sacrificing policy performance. The framework's effectiveness was further validated on ANYmal and Unitree Go2 robots, demonstrating its ability to achieve high-dimensional locomotion control with less simulation experience. AI
