Abstract: Provided is a transmitting device for a cart with an auto following function, which can sense the position and moving path of a user and move while following the user.
The transmitting device for a cart provides a sensing and communication function such that the cart with the auto following function can sense and follow the position of the transmitting device. Thus, the cart can sense and follow the position of the transmitting device.
Furthermore, since the transmitting device for a cart can be conveniently worn like a watch, a user's convenience can be improved.
