New TACLO framework enhances robot locomotion on unstructured terrain

Researchers have developed a new framework called TACLO (Trajectory-Level Automatic Curriculum Learning) to improve the training of legged robots for navigating unstructured terrain. TACLO generates training tasks directly from terrain maps, using an evaluator to learn a difficulty function for the current policy and a sampler to propose new trajectories. This iterative process continuously matches the curriculum to the evolving policy, resulting in a 56.3% improvement in trajectory success rate compared to direct training without a curriculum. The framework also outperformed handcrafted curriculum learning methods, showing an 18.5% increase in success rate on difficult terrain tasks and up to 39.74% improvement when evaluated from diverse approach directions.
