The invention relates to a mobile robot loaded with a suspending shock absorption mechanism. The mobile robot loaded with the suspending shock absorption mechanism comprises a chassis and a multi-layer support, wherein mobile system hardware, an infrared ranging sensor, an ultrasonic sensor and a laser radar are installed on the chassis; an industrial control machine and a vision sensor are arranged on the multi-layer support; the mobile system hardware comprises a base plate notch, a welding body, a motor, a suspending support, a driving wheel, a spring seat, a spring, a bearing and a bearing block; and the driving wheel and the motor are movably connected with a robot body via the spring. The mobile robot loaded with the suspending shock absorption mechanism can dive steadily on the ground with hollows, and also can use the own mechanism to steadily cross obstacles, monitor positioning information of the robot in real time, explore and plan a path, and acquire an overall map, and thus human face recognition and intelligent tracing can be achieved; the mobile robot loaded with the suspending shock absorption mechanism is simple in structure, convenient to operate, steady and safe in driving, and extremely strong in convenience and practicability.
