Abstract: A system and a method for following a target are disclosed. The system includes steps of: A. providing a signal transmitting RF module mounted on a target, a signal receiving RF module on a moving carrier, and at least 3 laser rangefinders aside the signal receiving RF module; B. calculating an estimated distance and a directional angle; C. driving the moving carrier toward the target while maintaining the directional angle substantially 0 degree; D. repeating step B and step C until the estimated distance is shorter than a control exchange distance; E. dynamically tracking the target by one of the laser rangefinders so that a relative distance between said laser rangefinder and the target can be successively calculated while calculating the estimated distance and the directional angle; and F. driving the moving carrier to keep the relative distance within a predetermined range and maintain the normal direction substantially toward the target.
