1. A robot, comprising a robot body, a detection system, and a controller, wherein the robot body comprises a mobile chassis, the mobile chassis comprises a suspension system, and the detection system and the suspension system are electrically connected to the controller; and
the detection system is configured to detect operating information of the robot body, the controller is configured to control the suspension system to adjust a suspension hardness of the suspension system based on the operating information, and the operating information comprises ground information during operation of the robot body and pose information of the robot body;
wherein the pose information comprises a swing amplitude of the robot body, and the detection system comprises a fourth detection member configured to detect the swing amplitude;
wherein when the swing amplitude is greater than or equal to a preset amplitude, the controller controls the suspension system to adjust the suspension hardness of the suspension system from a first suspension hardness range to a fifth suspension hardness range, wherein the fifth suspension hardness range is less than the first suspension hardness range;
wherein at least three fourth detection members are arranged, and the fourth detection members are respectively located on an upper portion, a middle portion, and a lower portion of the robot body;
wherein each fourth detection member is an inertial measurement unit configured to detect an acceleration and a rotational speed at a mounting position of the inertial measurement unit, when the robot is in a swinging state, a front-to-rear acceleration and a left-to-right acceleration detected by the inertial measurement unit arranged on the upper portion are greater than those detected by the inertial measurement units arranged on the middle portion and the lower portion.
