Apparatus and method for aggregate collection

1. An apparatus, comprising:

a floatable structure configured to be disposed in a water body, the floatable structure comprising:

a body having a substantially spherical surface and including a storage space within the body;

an opening in the body, wherein the opening is configured to form a passage to the storage space; and

a filter structure configured to extend circumferentially in the storage space to allow an aggregate of a particular aggregate size in the storage space; and

a control assembly coupled to the body, the control assembly is configured to set a mesh size of the filter structure to control a collection of the aggregate present in the water body, into the storage space through the opening and the filter structure of the set mesh size,

wherein the collection is controlled when the floatable structure is at least partially immersed in the water body.

2. The apparatus according to claim 1 , wherein the filter structure is one of a semi-permeable membrane or a selectively permeable membrane.

3. The apparatus according to claim 1 , wherein the opening is a slit in the body.

4. The apparatus according to claim 1 , wherein the body comprises a first hemispherical portion and a second hemispherical portion, and

wherein the first hemispherical portion is coupled to the second hemispherical portion so as to form the substantially spherical surface.

5. The apparatus according to claim 1 , wherein the control assembly comprises:

at least one actuator to control movement of the floatable structure, and

a suction device to control the collection of the aggregate.

6. The apparatus according to claim 1 , wherein the control assembly comprises at least one actuator to rotate the floatable structure along a vertical axis when the floatable structure is at least partially immersed in the water body.

7. The apparatus according to claim 1 , wherein the control assembly is further configured to control a movement of the floatable structure when the floatable structure is at least partially immersed in the water body.

8. The apparatus according to claim 7 , wherein the movement corresponds to one of a rotation of the floatable structure, a translation of the floatable structure, or a combination of the rotation and the translation.

9. The apparatus according to claim 7 , wherein the control assembly is further configured to control the movement of the floatable structure based on a first route for navigation of the floatable structure on the water body.

10. The apparatus according to claim 9 , wherein the control assembly is further configured to:

determine a fill level of the storage space based on the collection of the aggregate along the first route;

compare the determined fill level with a defined threshold fill level; and

control the movement of the floatable structure along a second route based on the comparison.

11. The apparatus according to claim 10 , wherein the second route comprises a dumping location, and

wherein the control assembly is further configured to transfer the aggregate from the storage space to the dumping location.

12. The apparatus according to claim 1 , further comprising an anchor,

wherein the control assembly is further configured to release the anchor in the water body so as to limit a movement of the floatable structure beyond a specific boundary.

13. The apparatus according to claim 1 , wherein the control assembly is further configured to:

communicate operational information to a control node within a communication range of the control assembly based on the collection of the aggregate,

wherein the operational information comprises a current status of the collection and a current position of the apparatus; and

receive a user input based on the communicated operational information.

14. The apparatus according to claim 13 , wherein the control assembly is further configured to control a movement of the floatable structure based on the received user input.

15. The apparatus according to claim 13 , wherein the control assembly is further configured to control the collection of the aggregate based on the received user input.

16. The apparatus according to claim 1 , wherein the control of the collection corresponds to a control of one or more of a rate, an aggregate volume, or an aggregate weight.

17. A method, comprising:

disposing a floatable structure in a water body, the floatable structure comprising:

a body having a substantially spherical surface and including a storage space within the substantially spherical surface; and

an opening on the body, wherein the opening is configured to form a passage to the storage space;

filtering an aggregate from the water body through a filter structure, wherein the filter structure is configured to extend circumferentially in the storage space to allow the aggregate of a particular aggregate size in the storage space;

set a mesh size of the filter structure to allow the aggregate of the particular aggregate size in the storage space; and

controlling a collection of the aggregate in the water body, into the storage space through the opening and the filter structure of the set mesh size,

wherein the collection is controlled when the floatable structure is at least partially immersed in the water body.

18. The method according to claim 17 , further comprising controlling a movement of the floatable structure when the floatable structure is at least partially immersed in the water body.
