System of guidance and positioning relative to a fixed station (

1

) for an autonomous mobile robot (

7

) utilizing at least a directional infra-red beam (

2

′) emitted by the fixed station, the mobile robot being provided with a directional system of detection (

10

a

, 10

b

) of infra-red emission connected to a microcomputer incorporated in the said robot, the robot moving on a work surface in an essentially random manner, the microcomputer (

44

) including an algorithm able to control the return to fixed station (

1

) by displacement of the robot (

7

) towards the direction of emission of said infra-red beam (

2

′), characterized in that the infra-red beam (

2

′) is a narrow directional beam and in that the system of detection (

10

a

, 10

b

) is located on a frame at the center of rotation of the robot (

7

), oriented in the direction of movement of the robot, precise positioning in the fixed station (

1

) being carried out by rotation of the machine around a vertical axis according to an algorithm based on the detection of the narrow beam (

2

′).
