Abstract: A robot foot structure for being used in conjunction with the main body structure of a humanoid robot is provided, the robot foot structure being connected to a bottom of the main body structure, wherein the robot foot structure includes a sole plate and a buffering mechanism provided on the sole plate, the buffering mechanism is configured to be connected between the sole plate and the main body structure of the humanoid robot for buffering a load acted on the robot foot structure generated by the weight of the main body structure during walking of the robot foot structure. A load generated by the weight of the main body structure during walking is acted on the buffering mechanism which in turn absorbs an impact resulted from the load as the robot foot structure touches the ground, such that the service life of the robot foot structure can be extended.
