Description

[0026] These and other features of the invention will be elucidated in conjunction with the accompanying drawings.

[0027] FIG. 1 shows a perspective view of a device according to the invention.

[0028] FIG. 2 shows a schematic view of the device according to FIG. 1.

[0029] In FIG. 1, a device 1 is shown. The device comprises a spherical housing 2 made of aluminum. In the housing, a plurality of cameras 3 are arranged and fixed to the housing 2 with overlapping fields of view. In addition to this, a plurality of light emitting diodes 4 is fixed to the housing 2 via a triangle shaped heat sinks 5 made of copper which are, with the bottom connected to the housing 2, and with the top connected to the light emitting diodes 4. Housing 2 comprises a number of housing segments, of which housing segment 6 is shown hinged outwardly from its normally closed position, allowing inspection of the interior of housing 2. Device 1 furthermore comprises a foot 7 which is connectable to a movable frame (not shown) through connection 8. A router (not shown) is arranged in foot 7. Device 1 is furthermore provided with a fan inlet 9 at the top of the housing 2. Device 1 furthermore comprises antennas 15, connected to the router, and an omnidirectional microphone 16.

[0030] In FIG. 2, the device 1 is shown without cameras 3 and light emitting diodes 4. The housing 2 is provided with a fan inlet 9 and fan outlet 10 at the bottom of the housing 1. The housing is arranged on a movable frame 11 with wheels 12, movable over a floor 13. Fans 14, shown in dotted lines are arranged within the housing 2 arranged for drawing air from the outside of the housing 2 through and outward from the housing 2.

[0031] Furthermore, publication US 2016/0261829 A1 discloses a device comprising a spherical housing, a plurality of cameras, arranged to and projecting outwardly from the housing and a plurality of light emitting diodes, arranged to and projecting outwardly from the housing. In this device, the light emitting diodes are recessed within the housing. In this device, still a large amount of heat is transferred to the housing.
