- FIGs 2a and 2b schematically show another embodiment of a mobile 30 combined movement of the invention.
- the mobile 30 is identical to the mobile 10 shown in Figures 1a and 1b. Indeed, the mobile 30 with combined movement can move on a horizontal plane 14.
- the mobile 30 comprises a body 9 comprising a contact zone 17 on the horizontal plane 14.
- the mobile 30 with combined movement comprises a cam 31 rotatable relative to the body 9 about a cam axis X.
- the cam 31 has a contact surface 32 in contact with the horizontal plane 14 during its rotation.

- the cam 1 1 slides at the point of contact.
- the mobile 10 is no longer rotatable about the vertical axis Z.
- the cam 1 1 is eccentric and the second angular sector 19 has two zones of linear radius variation, it follows that when the cam 1 1 is rotatable about the cam axis X and in contact with the horizontal plane 14 at the second portion 1 6, the cam 1 1 slides without rolling on the horizontal plane 14 and the body 9 connected to the cam 1 1 at the cam axis of the cam 21 rotates around the Y axis. More precisely, since the contact with the horizontal plane 14 is at the level of the cam 1 1 and the contact zone 17, the upper part of the mobile 10 performs a translation. The translation performed is determined by the shift of the point C with respect to the point O.
- the invention also applies to a cam of circular shape and non-eccentric, that is to say for a wheel.

- the frequency can for example be adapted according to the angular velocity of the cam 1 1, and n ' is not necessarily the same frequency as that implemented during the first phase of rotation.
- Figures 3f to 3h show the return of the mobile 10 from its tilted position to its vertical position.
- the image sensor 50 can produce images during the entire duration of the second phase of rotation or only during the first part of this phase when the mobile 10 goes from a vertical position to a tilted position or only during the second part of this phase when the mobile 10 goes from a tilted position to a vertical position.
- FIGS. 4a and 4b show schematically the views taken by the mobile 10 combined movement according to the invention after two cycles of operation. Each cycle is composed of two rotations, one resulting in a vertical translation and the other in a rotation.
- the mobile 10 has carried out a first cycle making it possible to scan sector 53 vertically and to scan sector 54 by rotation.
- FIG. 4b mobile 10 has carried out a second cycle enabling sector 55 and FIG. to sweep sector 56 by rotation.
- the second phase is a phase of immobilization of the mobile 10.
- the mobile 10 only scans the sectors 54 and 56.
- the immobilization phases of the mobile 10 can then serve as a control loop. delay for example to allow the mobile 10 to transmit the images produced during the rotation phase to an external storage medium wireless connection.
- FIG. 5 diagrammatically represents the totality of the views taken by the combined movement mobile device 10 according to the invention, after several cycles of operation, corresponding to a rotation of 360 ° of the mobile 10 around itself.
- the mobile 10 has carried out a first cycle for vertically scanning the sector 53 and rotatingly scanning the sector 54.

- the image sensor 50 of the mobile 10 has scanned the sectors shown in FIG. the mobile 10 provides a three-dimensional graphical representation of its environment. This graphic representation may be more or less refined depending on the ability of the image sensor to produce a more or less wide image around the axis of orientation 51.

- the digital image storage medium is able to save a succession of images produced as and when the cam 1 1 rotates about the cam axis X. It is then possible to have the digital image storage medium mobile 10 several cycles of operation so that it saves the succession of corresponding images. After carrying out the operating cycles, the storage medium (possibly the cam 1 1) containing the succession of images may be used elsewhere to make the succession of images available to a user.

- This embodiment of the mobile 60 with a combined movement differs from the embodiment shown in FIGS. 3a to 3h by the shape of its body 9.
- the body 9 has a substantially rounded base so that that the contact zone 17 on the horizontal plane 14 forms a point of contact, whatever the phase in which the mobile 60 with combined movement, ie in phase of rotation about the axis, is located.
- vertical Z as shown in Figures 6 and 7, or in phase of rotation about the Y axis, as shown in Figure 8.
- the body 9 is configured to rotate relative to the horizontal plane 14 around the vertical axis Z perpendicular to the cam axis X when the first portion 15 rolls without sliding on the horizontal plane 14 and to rotate relative to the horizontal plane 14 about the horizontal axis Y perpendicular to the cam axis X and to the vertical axis Z when the second portion 1 6 slides without rolling on the horizontal plane 14.
- the center of gravity of the mobile is situated on a vertical axis passing between the contact surface of the cam 1 1 with the horizontal plane 14 and the contact zone 17 when the first portion 15 rolls without sliding on the horizontal plane 14. So when the second portion 16 slides without rolling on the horizontal plane 14, the body 9 sways forward, as shown in Figure 8, without risk of falling forward.
- This embodiment is particularly advantageous since the contact zone 17 with the horizontal plane 14 is always a point, which makes it possible to obtain a natural pivot effect at the center of the mobile and not at the edge of the mobile. This results in a better stability of the mobile.
- the natural pivot effect decreases the lever arm approximately by a factor of two, and thus the power of the motor required for rotating the cam can be divided by this factor.
- FIGS 9a, 9b, 9c, 9d schematically show different cam configurations according to the invention.
- the cam 1 1 is shown in a substantially flattened shape such as a disc. It is not beyond the scope of the invention with a two-dimensional or three-dimensional cam, for example of geometric shape with three dimensions of uniform or non-uniform contour

- the first portion 15 is wider in order to produce a greater contact force when this portion is in contact with the horizontal plane 14.
- the second portion 1 6 may be narrower to minimize the contact between the cam 1 1 and the plane horizontal 14 and promote the sliding of the cam 1 1 on the horizontal plane 14.
- FIGS. 9c and 9d represent cams whose first 15 and second 16 portions of the rolling surface 12 of the cam 1 1 have a fairly large width, the width of the first portion 15 being greater than the width of the second portion 16 to promote contact with the horizontal plane 14.
- the width of the second portion 1 6 is minimized as much as possible so that the cam 1 1 forms a point contact with the horizontal plane 14 when the second portion 16 is in contact with the horizontal plane 14.
- the width of the first portion 15 is greater than the width of the second portion 1 6.
- the invention thus comprises any cam of any shape having a first portion and a second distinct portion, each of the first and second portions having a distinct coefficient of friction, the coefficient of friction of the first portion being greater than the coefficient friction of the second portion.
- the invention makes it possible to obtain a mobile of very simple structure, little bulky and inexpensive, requiring no particular maintenance, being able to be rotated around itself and to translate vertically.
