Abstract
The present invention provides an automatic accompanying system, comprising an user and a accompanying unit following the user, wherein the accompanying unit follows the user according to the user's movement and turning action. The automatic accompanying system comprises: a first pointing unit, a relative position sensing unit and a control module, wherein the first pointing unit detects a facing direction of the user. The accompanying unit collects an orientation signal of the user and a relative position signal for analyzing and generates an instruction signal to control itself to move and turn. Through the said accompanying system, the purposes of accompanying a user in multiple positions, like in the front, behind, by the side, above, increasing safety, reducing the risk of loss, and saving users from paying too much attention on operating the system can be achieved, and it facilitates user to carry out related applications.
