Abstract

A robot includes a wheeled chassis (12), actuators that ensure the movement of the wheeled chassis (12), and command-control element to which sensors send information, characterized in that the wheeled chassis (12) includes two driving wheels (16) that have axes of rotation in a transverse plane and two wheeled elements (22) along at least two axes of rotation and/or pivoting that each have a vertical pivoting axis (24) that is arranged in the longitudinal median plane of the robot, and in that it includes a laser or radar that is arranged in a horizontal slot (38) that is made in the covering of the robot whose bottom has shapes that make it possible to optimize the field of vision of the laser.

Claims

1. Robot that can be used for personal home assistance, comprising a wheeled chassis (12), actuators (26) that ensure the movement of the wheeled chassis (12), and command-control means (30) to which sensors send information, characterized in that the wheeled chassis (12) comprises two driving wheels (16) that have axes of rotation in a transverse plane and two wheeled elements (22) along at least two axes of rotation and/or pivoting that each have a vertical pivoting axis (24) that is arranged in the longitudinal median plane of the robot, and in that it comprises a laser or radar (44) that is arranged in a horizontal slot (38) that is made in the covering of the robot whose bottom has shapes that make it possible to optimize the field of vision of the laser or radar.

2. Robot according to claim 1, wherein the bottom of the horizontal slot (38) comprises two sections that are arranged symmetrically and that form an angle on the order of 240°

.

3. Robot according to claim 1, wherein it comprises an ultrasound sensor barrier (42).

4. Robot according to claim 3, wherein it comprises a covering that has an essentially square or rectangular horizontal section with rounded angles, and wherein the ultrasound sensor belt comprises ultrasound sensors (42.1) at the covering angles, an ultrasound sensor (42.2) at each lateral face of the robot, an ultrasound sensor (42.3) on the rear face, and two ultrasound sensors (42.4) that are arranged symmetrically on the front face of the robot.

5. Robot according to claim 1, wherein at least one of the wheeled elements (22) along at least two axes of rotation and/or pivoting can move translationally along its pivoting axis (24) to allow the robot access to inclined planes.

6. Robot according to claim 5, wherein return means are provided to keep the wheeled element (22) in contact with the ground along at least two axes of rotation and/or pivoting.

7. Robot according to claim 6, wherein the return means exert a force that makes it possible to obtain—

at the driving wheels (16)—

an adhesion to the ground that does not go below a determined threshold.

8. Robot according to claim 1, wherein it comprises a covering with an upper board (36) that is essentially horizontal and that comprises means for attaching accessories.

9. Robot according to claim 2, wherein it comprises an ultrasound sensor barrier (42).

10. Robot according to claim 2, wherein at least one of the wheeled elements (22) along at least two axes of rotation and/or pivoting can move translationally along its pivoting axis (24) to allow the robot access to inclined planes.

11. Robot according to claim 3, wherein at least one of the wheeled elements (22) along at least two axes of rotation and/or pivoting can move translationally along its pivoting axis (24) to allow the robot access to inclined planes.

12. Robot according to claim 4, wherein at least one of the wheeled elements (22) along at least two axes of rotation and/or pivoting can move translationally along its pivoting axis (24) to allow the robot access to inclined planes.

13. Robot according to claim 2, wherein it comprises a covering with an upper board (36) that is essentially horizontal and that comprises means for attaching accessories.

14. Robot according to claim 3, wherein it comprises a covering with an upper board (36) that is essentially horizontal and that comprises means for attaching accessories.

15. Robot according to claim 4, wherein it comprises a covering with an upper board (36) that is essentially horizontal and that comprises means for attaching accessories.

16. Robot according to claim 5, wherein it comprises a covering with an upper board (36) that is essentially horizontal and that comprises means for attaching accessories.

17. Robot according to claim 6, wherein it comprises a covering with an upper board (36) that is essentially horizontal and that comprises means for attaching accessories.

18. Robot according to claim 7, wherein it comprises a covering with an upper board (36) that is essentially horizontal and that comprises means for attaching accessories.

19. Robot according to claim 10, wherein it comprises a covering with an upper board (36) that is essentially horizontal and that comprises means for attaching accessories.

20. Robot according to claim 11, wherein it comprises a covering with an upper board (36) that is essentially horizontal and that comprises means for attaching accessories.
