When the user moves, the stroller will constantly update the changes in the user's position information. When the distance between the user and the stroller is greater than a certain value, the motor controller controls the driving brake motor 38 and the steering motor 6 to achieve the purpose of following. The set sound can play music to coax sleep.

[0044] The overall working principle of the present invention is as follows:

[0045] The first servo motor 18 drives the first screw 17 to rotate, which can drive the storage shell 2 to rise and fall along the corresponding connecting block 33 through the limit rod 10, so that the height of the cradle 15 can be adjusted, which is convenient for the user to adjust according to the height, and convenient for observing and caring for the baby. The set rocking component can drive the cradle 15 to swing back and forth, which is convenient for coaxing the baby to sleep. Specifically, the second servo motor 24 drives the reciprocating screw rod 23 to rotate, which can drive the slider 25 to move back and forth along the slide rail 22, thereby driving the connecting seat 27 on the first rotating shaft 26 to move back and forth, and then through the insertion rod 28 and the sleeve 32, the cradle 15 can be driven to swing back and forth around the first supporting frame 11 through the second rotating shaft 31 at the bottom of the second supporting frame 14. The user connects to the Bluetooth module through the mobile phone Bluetooth, and the three-eye camera and laser radar obtain surrounding The surrounding information is compared with the user location information obtained by the Bluetooth module to obtain the user's location information and some features in the environment. When the user moves, the baby stroller will constantly update the changes in the user's location information. When the distance between the user and the baby stroller is greater than a certain value, the motor controller controls the driving of the brake motor 38 and the steering motor 6 to achieve the following purpose. The set audio can play lulling music. During the following process, other objects in the environment will be regarded as obstacles. After fusing the information obtained by the three-eye camera and the lidar, the control system will plan the obstacle avoidance path in advance according to the obstacle avoidance strategy. The baby stroller will travel along the planned path. When the surrounding environment is very complicated and the baby's safety cannot be effectively guaranteed, the baby stroller will stop and brake. At this time, the brake motor 38 is powered off and the brake assembly is locked, so that braking can be performed.
