HiRT introduces a transformative hierarchical framework that enables robots to perform complex tasks with higher control frequency while maintaining intelligence.

• Dual-layer architecture separates high-level planning from low-level control, achieving up to 167Hz operation frequency
• Reduces computational demands while preserving the capabilities of large Vision-Language-Action models
• Demonstrates superior performance in dynamic manipulation tasks compared to existing approaches
• Maintains high success rates even in challenging scenarios requiring rapid adaptation

This innovation addresses a critical engineering challenge: enabling robots to respond quickly in dynamic environments without sacrificing the intelligence provided by large models. The hierarchical approach offers a practical pathway to deploy advanced AI in real-world robotic applications where both speed and intelligence matter.
