WHAT IS CLAIMED IS:

1. A whipstock system comprising:

a whipstock body;

a control unit mounted on or in the whipstock body, the control unit comprising transmitters and receivers operable to receive commands from an external source; activatable components mounted on or in the whipstock body, and

a hydraulic system in the whipstock body, the hydraulic system in

communication with the control unit, the hydraulic system including at last one hydraulic power unit operable to repeatedly activate and de-activate the activatable components.

2. The whipstock system of claim 1, wherein the activatable components comprise at least one slips assembly and at least one seal assembly.

3. The whipstock system of claim 2, wherein the activatable components comprise an upper slips assembly and a lower slips assembly.

4. The whipstock system of claim 1, wherein the hydraulic system comprises: a reservoir and an expansion chamber in the whipstock body; and

a pump in the whipstock body in fluid communication with the reservoir and the expansion chamber;

wherein transfer of fluid from the reservoir to the expansion chamber activates at least one of the activatable components.

5. The whipstock system of claim 4, wherein the control unit comprises:

one or more processors; and

a computer-readable medium storing instructions executable by the one or more processors to perform operations comprising:

receiving, from the external source, instructions to perform whipstock operations within the wellbore; and

transmitting, to the hydraulic system, at least a portion of the instructions.

6. The whipstock system of claim 5, wherein the hydraulic power unit is operatively coupled to the one or more processors and the hydraulic power unit configured to receive at least the portion of the instructions from the one or more processors.

7. The whipstock system of claim 5, wherein the pump is hydraulically connected to an upper slips assembly or a lower slips assembly.

8. The whipstock system of claim 7, comprising a mandrel movable to engage an anchor portion of the upper slips assembly or lower slips assembly.

9. The whipstock system of claim 4, wherein the hydraulic pump is hydraulically connected to the at least one seal assembly.

10. The whipstock system of claim 4, wherein the operations further comprise: receiving, from the whipstock assembly, status signals representing a whipstock status of the at least one of the plurality of whipstock assembly; and

transmitting, to the surface of the wellbore, the status signals.

11. The whipstock system of claim 4, wherein the external source comprises: one or more transmitters at the surface, the one or more transmitters configured to transmit the instructions to the one or more processors; and

one or more receivers at the surface, the one or more receivers configured to receive the status signals from the one or more processors.

12. The whipstock system of claim 11, wherein the one or more transmitters and the one or more receivers are configured to communicate wirelessly with the one or more processors.

13. The whipstock system of claim 4, wherein the control assembly further comprises a power source mounted on or in the whipstock body, the power source electrically coupled to the one or more processors.

14. The whipstock system of claim 13, wherein the power source is a wireless, stand-alone power source.

15. The whipstock system of claim 14, wherein the wireless, stand-alone power source is a lithium battery.

16. The whipstock system of claim 14, wherein the hydraulic system comprises a check valve.

17. A method of deploying a whipstock in a wellbore, the method comprising:

receiving, by a control assembly deployed within a wellbore, instructions to perform whipstock operations within the wellbore;

transmitting, by the control unit, at least a portion of the instructions to a hydraulic system on a whipstock assembly; and

activating at least one independent hydraulic power unit of the hydraulic system in response to the portion of the instructions transmitted by the control unit to activate components of the whipstock assembly.

18. The method of claim 17, wherein activing at least one independent hydraulic power unit of the hydraulic system to activate components of the whipstock assembly comprises activating at least one independent hydraulic power unit of the hydraulic system to activate a slips assembly or a seal assembly of the whipstock assembly.

19. The method of claim 17, comprising activating at least one independent hydraulic power unit of the hydraulic system in response to the portion of the instructions transmitted by the control unit to deactivate components of the whipstock assembly.

20. The method of claim 17, wherein activating at least one independent hydraulic power unit of the hydraulic system comprises pumping fluid from a reservoir in the whipstock assembly to an expansion chamber of the whipstock assembly.
