Researchers have developed a novel two-stage deep reinforcement learning framework to enable quadrupedal robots, specifically the Unitree Go2, to navigate and adapt to various indoor staircases for firefighting missions. The approach first trains the robots on abstract pyramid terrain in Isaac Lab and then transfers this learned policy to more complex, realistic indoor staircases, including straight, L-shaped, and spiral designs. This method allows for unified learning of navigation and locomotion using only local height-map perception, demonstrating successful policy generalization across diverse stair shapes and providing an analysis of performance under increasing difficulty.
