➀ Researchers at the University of Illinois Urbana-Champaign have developed a machine-learning framework called HUMANUP that enables humanoid robots to stand up autonomously after falling.

➁ The framework uses reinforcement learning (RL) to identify effective limb trajectories and refine initial motions into smooth and controlled movements.

➂ Tests in simulations and real-world settings using the Unitree G1 humanoid robot showed promising results, indicating the robot can autonomously recover from falls regardless of its position or the surface beneath it.
