Researchers in China and Hong Kong have developed an AI framework that teaches humanoid robots to stand up quickly from an idle position.The framework, called Humanoid Standing-up Control (HoST), uses reinforcement learning to allow the robot to learn through trial and error.The HoST framework was first trained in simulations and then deployed in a Unitree G1 Humanoid Robot for experimental testing.The successful results pave the way for integrating standing-up control into existing humanoid systems, expanding their real-world applicability.
