On August 26, Hangzhou Unitree Technology Co., Ltd. was awarded a patent for its groundbreaking design of a "humanoid robot foot and humanoid robot." This patent epitomizes advancements in humanoid robot technology, introducing a novel foot structure specifically tailored for such robots. The foot is meticulously crafted with a foot shell and an integrated elastic foot sole, both firmly interconnected. Inside the elastic foot sole, multiple deformable air chambers are strategically positioned, connected to the exterior via air tubes that seamlessly penetrate the foot shell.

The ingenuity of this design lies in its ability to safeguard vulnerable components, such as sensors, from direct ground impact. By positioning only the deformable air chambers within the elastic foot sole, it significantly mitigates the risk of collision damage. Furthermore, the design leverages the spatial changes of the air tubes and air chambers to transmit compression information, enabling swift responsiveness unaffected by motor characteristics. This integrated approach not only enhances performance but also simplifies the replacement and maintenance of the foot components, underscoring Unitree's commitment to innovation and practicality.
