Disclosed is a control system suitable for controlling a ceiling structure of a carrier. The control system includes: a processing module; a sensor module, electrically coupled to the processing module and senses an external wind-force; and a driving device, electrically coupled to the processing module and controls unfolding and folding of the ceiling structure, wherein when the processing module determines through the sensor module that the external wind-force is greater than a predetermined wind-force threshold, the driving device is controlled such that the ceiling structure shelters at least part of the carrier. Also disclosed is a carrier including a ceiling structure, and a control method suitable for controlling a ceiling structure of a carrier.

In accordance with an embodiment, a mobile infant care device includes a carrier having an inner space configured to hold an infant positioned therein, and driving wheels provided at a lower part of the carrier; a monitoring system affixed to the carrier and configured to monitor a state of the infant positioned in the inner space of the carrier; a driving system coupled to the driving wheels, the driving system configured to move a position of the carrier by driving the driving wheels; a communication system configured to wirelessly transmit a monitoring result of the monitoring system to a user terminal device or to wirelessly receive an operation input from the user terminal device; and a controller configured to cause the driving system to move the carrier based on the monitoring result of the monitoring system or the operation input received through the communication system.
