Abstract: It is described an autonomous system for tracking an individual, comprising: wheeled vehicle; 3D depth camera, distance and/or touch sensors; at least two motors, each to drive one or more wheels respectively from both sides, left and right, of the mentioned vehicle; data processing module, comprising a decision unit configured to: if the 3D depth camera detects that the distance between the system and the individual to follow is inferior to a predetermined limit, decrease the speed of the two motors; if the 3D depth camera detects that the person to be followed exceeds a predetermined limit on the left or right of a horizontal predefined point, increase the engine speed on the right, slowing the speed of the left engine, or vice versa.
