Abstract: The present disclosure relates to a smart stroller and a method of controlling the same. The smart stroller includes a sensor part for sensing various information regarding a space in which a baby is seated and information regarding the surrounding environment in which the smart stroller is traveling. The sensed information is transmitted to a controller so as to be calculated as information for controlling operation of the smart stroller or information for informing to a user. This may enable the smart stroller to travel in a stable manner. This may also allow the user to check the state of the baby in real time and take necessary action.

Abstract: A cart can include a body having driving wheels mounted to left and right sides thereof; a motor configured to rotate the driving wheels; a frame comprising a lower part connected to the body, the frame extending upwards from the lower part; a handle connected to the frame; a sensor unit including a tilt sensor configured to detect a tilt of the body, and a touch sensor configured to detect whether the handle is grasped; and a controller configured to in response to determining that the handle is not grasped based on data detected by the touch sensor, determine whether the cart is located on a slope based on data detected by the tilt sensor, change a control parameter of the motor based on whether the cart is located on the slope and perform a braking operation in different ways based on whether the motor is rotating.

Abstract: The present disclosure relates to a cart unit and a method of controlling the same. The cart unit includes a touch sensor that is mounted inside a handle to sense an object such as a user's hand approaching the handle, and a controller that calculates operation information according to information sensed by the touch sensor. The cart unit can be operated according to the calculated operation information. This can result in improving user convenience.
