According to an embodiment, the surface of the ball structure 300 may be a sphere. The description that the surface of the ball structure 300 is a sphere may mean that the surface has an “entirely or partially” or “approximately or completely” sphere-type surface.
According to an embodiment, the outer ring structure 400 is configured to be separate from the ball structure 300, and may move independently of the ball structure 300. Movements of the outer ring 400 may be implemented through an interaction with the ball structure 300 while being separated from the ball structure 300.
According to an embodiment, the outer ring structure 400 may be configured to remain separated from the surface of the housing 301 of the ball structure 300 using principles of magnetic levitation.
According to an embodiment, the ball structure 300 and the outer ring structure 400 may include magnet units, respectively, and respective magnet units may be positioned to face each other. Accordingly, the outer ring structure 400 of the electronic device 200 (for example, the electronic device 101) may be spaced apart from the ball structure 300 by a predetermined distance such that the outer ring structure 400 is substantially levitated.
According to an embodiment, the outer ring structure 400 may be a ring-shaped member having a predetermined thickness. The inner diameter of the outer ring structure 400 may be larger than the outer diameter of the ball structure 300 such that the outer ring structure 400 surrounds the ball structure 300.
According to an embodiment, the outer ring structure 400 and the sphere-type ball structure 300 may form concentric circles when viewed from the top and thus have the same center c1. As shown in
Referring to the direction components illustrated in
According to an embodiment, the ball structure 300 may roll in a first direction while being placed on the floor, and may yaw with reference to a rotating axis perpendicular to the first direction. According to an embodiment, assuming that a virtual plane defined by the direction components Xc and Zc is the floor on which the electronic device 200 moves, the ball structure 300 may roll in the first direction (for example, the direction parallel with the Xc direction) of the virtual plane defined by the direction components Xc and Zc, and the ball structure 300 may change directions by rotating with respect to an axis parallel to the direction component Yc.
According to an embodiment, the ball structure 300 and the outer ring structure 400 are coupled to each other and move together such that, when the ball structure 300 moves, the outer ring structure 400 can also move. The outer ring structure 400 can move independently of the ball structure 300, and the inclination by which the outer ring structure 400 is oriented may tilt (or pitch) with respect to the ball structure 300. Further, the outer ring structure 400 may rotate in its circumferential direction. According to an embodiment, prior to any movement of the ball structure 300, the outer ring structure 400 may be initially horizontal with the floor. When the ball structure 300 is moving on the other hand, the outer ring structure 400 may slope around the center c1 such that, for example, a camera module 480 provided on the outer ring structure 400 faces in the upward direction, as shown in
According to an embodiment, when the ball structure 300 is moving in a direction parallel with the direction component Xc axis, the outer ring structure 400 may move while remaining parallel with a virtual plane defined by the direction components Xc and Zc. As another example, while the ball structure 300 moves, the outer ring structure 400 may move while remaining inclined instead of being parallel with the virtual plane defined by the direction components Xc and Zc. As still another example, the inclination of the outer ring structure 400 may vary while the ball structure 300 moves.

According to an embodiment, the housing 301 may include an upper housing 301a and a lower housing 301b. According to an embodiment, the upper housing 301a and the lower housing 301b may be hemispheres coupled to each other so as to form a sphere-shaped housing 301 as a whole. According to an embodiment, the fastening surface 302a of the upper housing 301a and the fastening surface 302b of the lower housing 301b may have various fastening structures. For example, screw coupling may be adopted, or separate fastening members may be employed. The upper housing 301a and the lower housing 301b may be firmly fastened to each other such that the housings are not separated when the ball structure 300 travels on uneven surfaces or traverses stairs.
According to an embodiment, the housing 301 may have a space formed therein such that various constituent elements of the electronic device (for example, the electronic device 101) are mounted therein. Compared with the space, the thickness of the housing 301 may be relatively thin, and the housing 301 may be made of a material for preventing scratching, hollowing, or fracturing.
According to an embodiment, the housing 301 may be made of various materials such as polyethylene, polyethylene terephthalate, polycarbonate, glass, acrylic resin, and/or synthetic resin. According to an embodiment, the housing 301 may be made of a non-transparent material. According to another embodiment, the housing 301 may be made of a transparent material such that the interior is visible from the outside.
According to an embodiment, various constituent elements of the electronic device (for example, the electronic device 101) arranged inside the ball structure 300 may be primarily housed by the lower housing 301b. Such arrangement of various heavy constituent elements in the lower housing 301b may lower the center of gravity of the electronic device, thereby enabling stable operation of the electronic device. Various constituent elements of the electronic device (for example, the electronic device 101) arranged inside the ball structure 300 may include a power management module (for example, the power management module 188 of
According to an embodiment, a first driving module 310 may be provided to enable travel for the ball structure 300. According to an embodiment, the first driving module 310 may include a first motor part 311 and a plurality of inclined wheels 314b and 314b. The plurality of inclined wheels may be divided into two inclined wheels, that is, a first inclined wheel 314a and a second inclined wheel 314b. The first inclined wheel 314a and the second inclined wheel 314b may face in opposite directions and may contact at least a part of the inner curved surface of the housing 301.
According to an embodiment, the first motor part 311 may be connected to a processor (for example, the processor 120) so as to receive a control input regarding the first driving module 310 and to drive the same. The first motor unit 311 may provide driving power that moves the first inclined wheel 314a or the first inclined wheel 314a and the second inclined wheel 314b. In connection with the plurality of inclined wheels 314a and 314b, the first inclined wheel 314a and the second inclined wheel 314b may both contact at least a part of the inner curved surface of the housing and may move simultaneously. To this end, the first inclined wheel 314a and the second inclined wheel 314b may have tapered shapes when viewed in the lateral direction.
According to an embodiment, the driving of the second inclined wheel 314b may be dependent on the driving of the first inclined wheel 314a. Alternatively, the second inclined wheel 314b may be driven independently of the first inclined wheel 314a. For example, when the first inclined wheel 314a is driven by the first motor part 311 (e.g. when the first inclined wheel 314a rotates due to it sharing a rotating axis with the first motor part 311), the second inclined wheel 314b may rotate together.
According to another embodiment, each of the first inclined wheel 314a and the second inclined wheel 314b may be connected to the first motor part 311. In this case, two objects may provide the first motor part 311 with driving power. For example, the first motor part 311 may include a plurality of motors (for example, a (1-1)th motor and a (1-2)th motor), the first inclined wheel 314a may be connected to the (1-1)th motor, and the second inclined wheel 314b may be connected to the (1-2)th motor. In this case, the first inclined wheel 314a may be synchronized with rotation of the (1-1)th motor and be moved accordingly, and the second inclined wheel 314b may be synchronized with rotation of the (1-2)th motor and be moved accordingly.
According to an embodiment, the inner curved surface of the housing 301 may be moved by the first inclined wheel 314a and the second inclined wheel 314b due to friction, and the housing 301 may accordingly roll in a first direction (for example, direction parallel with Xc direction) or yaw around an axis defined by a direction (for example, direction parallel with Yc direction) perpendicular to the first direction.
According to an embodiment, when the electronic device (for example, the electronic device 200) travels forward or backward, the first inclined wheel 314a and the second inclined wheel 314b may rotate in the same direction. According to another embodiment, when the electronic device (for example, the electronic device 200) yaws, the first inclined wheel 314a and the second inclined wheel 314b may rotate in different directions.
According to an embodiment, the first driving module 310 may have a weight member 315 arranged thereon. The weight member 315 is configured to be positioned on the lower part of the first driving module 310 and, according to an embodiment, may be positioned on the lower surface of the first motor part 311. So that the first driving module 310 is compactly provided inside the lower housing 301b, the weight member 315 may have a shape corresponding to shape of the inner curved surface of the lower housing 301b for the purpose of compact configuration.
According to an embodiment, in order to facilitate rolling and yawing of the ball structure 300, slipping between the first inclined wheel 314a, the second inclined wheel 314b, and the lower housing 301b, should be minimized. For example, parts of the first inclined wheel 314a, the second inclined wheel 314b, and the lower housing 301b that contact each other may be at least partially made of a material that can increase frictional force.
According to an embodiment, the electronic device (for example, the electronic device 200 of

The horizontal shaft member 331 may transfer driving power from the second driving module 330 to the inner ring structure 320, thereby driving the outer ring structure 400. Therefore, the horizontal shaft member 331 may have a high level of strength and may be firmly fastened to the inner ring structure 320.
The tilting member 332 may be coupled to at least a part of the horizontal shaft member 331 so as to rotate the horizontal shaft member 331 such that the inclination of the inner ring structure 320 can be adjusted. A plurality of gear trains 333 may be arranged inside the tilting member 332 such that the horizontal shaft member 331 can be tilted with reference to a horizontal axis (for example, an axis parallel with direction component Xc), and the inner ring structure 320 can also be tilted accordingly. For example, when the horizontal shaft member 331 is tilted with reference to an axis parallel with the direction component Xc, the inner ring structure 320 may slope at various angles with respect to the plane defined by the direction components Yc and Zc, along the inner surface of the housing 301.

According to an embodiment, a second motor member (not illustrated) may be coupled to each of the tilting member 332 and the rotating member 334 in order to independently control driving of the tilting member 332 and the rotating member 334. For example, the second motor member may include a plurality of motors (for example, a (2-1)th motor (not illustrated) and a (2-2)th motor (not illustrated)). For example, the (2-1)th motor may be coupled to the tilting member 332, and the (2-2)th motor may be coupled to the rotating member 334 such that the tilting member 332 and the rotating member 334 can be driven independently.

According to an embodiment, the inner ring structure 320 may include a body portion 321 and a first magnet containing portion 322, and may have a first magnet unit 323 provided in the first magnet containing portion 322. According to an embodiment, the outer ring structure 400 may include a body portion 410 and a second magnet containing portion 420 arranged to face the first magnet containing portion 322, and may have a second magnet unit 421 provided in the second magnet containing portion 420.
According to an embodiment, the first magnet unit 323 and/or the second magnet unit 421 may be a permanent magnet. According to another embodiment, the first magnet unit 323 and/or the second magnet unit 421 may be an electromagnet.

The shapes and arrangements of the first magnet unit 323 and the second magnet unit 421 disclosed herein are used as examples only. According to other embodiments, the first magnet unit 323 and the second magnet unit 421 may have various structures and shapes so that the outer ring structure 400 and the inner ring structure 320 are dynamically balanced, such that, for example, when the outer ring structure 400 and the inner ring structure 320 are moving, the relative position between the two elements is within an allowable range.
According to an embodiment, the electronic device (for example, the electronic device 200 of
For example, if the first magnet unit 323 and the second magnet unit 421 become increasingly misaligned during operation of the electronic device (for example, when the electronic device is moving), the outer ring structure 400 and the inner ring structure 320 may return to their original positions by the magnetic force generated between them. However, if the first magnet unit 323 is excessively misaligned from the second magnet unit 421, i.e. when the first magnetic unit 323 moves away from the second magnet unit 421 by greater than an allowed range, the dynamic balance may be broken. The present disclosure encompasses various shapes, numbers, and relative positioning of the first magnet unit 323 and the second magnet unit 421, as long as dynamic balance is maintained.

According to an embodiment, a repulsive force may act between the second magnet unit 421 arranged on the outer ring structure 400 and the first magnet unit 323. As explained above, magnets are arranged such that an attractive force acts between the second magnet unit 421 and the first magnet unit 323. If the dynamic balance between the second magnet unit 421 and the first magnet unit 323 is then broken, a part of the outer ring structure 400 may come to contact the housing 301, which may render the electronic device (for example, the electronic device 200) inoperable. Accordingly, according to an embodiment, a repulsive force may be provided between the second magnet 421 and the first magnet unit 323 to keep the outer ring structure 400 off the housing 301, such that, even if the dynamic balance is broken by an abruptly applied large external force, the electronic device (for example, the electronic device 200) can operate while the outer ring structure 400 and the housing 301 remain spaced apart by the repulsive force.
