Abstract

An actuator assembly that includes an angled bottom plate having an opposing first side face and second side face; a first set of one or more inflatable actuators engaging the first side face of the angled bottom plate; and a second set of one or more inflatable actuators engaging the second side face of the angled bottom plate. The first and second sets of inflatable actuators are configured to be separately fluidically inflated.

Claims (38)

1. A pneumatically actuated solar panel array system comprising:

a plurality of separate actuator assemblies that each include:

an angled bottom plate, the angled bottom plate having an opposing first side face and second side face,

a first set of one or more inflatable actuators engaging the first side face of the angled bottom plate,

a second set of one or more inflatable actuators engaging the second side face of the angled bottom plate, and

the first and second sets of inflatable actuators being configured to be separately pneumatically inflated, where the pneumatic inflation expands the inflatable actuators to control a pressure ratio between the first and second sets of inflatable actuators; and

a plurality of solar panels coupled to the actuator assemblies, the solar panels configured to be actuated based on inflation of the one or more inflatable actuators associated with the plurality of actuator assembles.

2. The pneumatically actuated solar panel array system of claim 1 , further comprising:

a first pneumatic channel operably coupled to each of the inflatable actuators of the first sets of inflatable actuators of the plurality of actuator assemblies and configured to inflate each of the inflatable actuators of the first sets of inflatable actuators simultaneously; and

a second pneumatic channel operably coupled to each of the inflatable actuators of the second sets of inflatable actuators of the plurality of actuator assemblies and configured to inflate each of the inflatable actuators of the second sets of inflatable actuators simultaneously.

3. The pneumatically actuated solar panel array system of claim 1 , wherein each of the first and second sets of inflatable actuators comprises no more than two inflatable actuators.

4. The pneumatically actuated solar panel array system of claim 1 , wherein the bottom plates of the actuator assemblies are V-shaped.

5. The pneumatically actuated solar panel array system of claim 1 , wherein the bottom plate and the first and second sets of one or more inflatable actuators collectively define a central axis of symmetry.

6. The pneumatically actuated solar panel array system of claim 1 , wherein each of the inflatable actuators comprises a rigid constraint disposed about a peripheral edge of the inflatable actuators.

7. An actuator assembly that comprises:

an angled bottom plate having an opposing first side face and second side face;

a first set of one or more inflatable actuators disposed engaging the first side face of the angled bottom plate;

a second set of one or more inflatable actuators disposed engaging the second side face of the angled bottom plate;

the first and second sets of inflatable actuators being configured to be separately fluidically inflated, where the fluidic inflation expands the inflatable actuators; and

one or more solar panels coupled to the actuator assembly, the one or more solar panels configured to be actuated based on inflation of the first and second sets of one or more inflatable actuators associated with the actuator assembly.

8. The actuator assembly of claim 7 , further comprising:

a first fluidic channel operably coupled to each of the inflatable actuators of the first set of inflatable actuators of the actuator assembly and configured to inflate each of the inflatable actuators of the first set of inflatable actuators simultaneously; and

a second fluidic channel operably coupled to each of the inflatable actuators of the second set of inflatable actuators of the actuator assembly and configured to inflate each of the inflatable actuators of the second set of inflatable actuators simultaneously.

9. The actuator assembly of claim 7 , wherein the angled bottom plate has an axis of symmetry.

10. An actuator assembly that comprises:

an angled bottom plate, the angled bottom plate having an opposing first side face and second side face, wherein the bottom plate of the actuator assembly is V-shaped;

a first set of one or more inflatable actuators engaging the first side face of the angled bottom plate; and

a second set of one or more inflatable actuators engaging the second side face of the angled bottom plate,

wherein the first and second sets of inflatable actuators are configured to be separately fluidically inflated.

11. The actuator assembly of claim 10 , further comprising one or more solar panels associated with the actuator assembly, the one or more solar panels configured to be actuated based on inflation of the one or more inflatable actuators associated the actuator assembly.

12. The actuator assembly of claim 10 , wherein the angled bottom plate is rotatably associated with one or more solar panels via a joint, the joint being disposed at an apex of the angled bottom plate.

13. The actuator assembly of claim 10 , further comprising:

a first fluid channel operably coupled to each of the inflatable actuators of the first set of inflatable actuators of the actuator assembly and configured to inflate each of the inflatable actuators of the first set of inflatable actuators simultaneously; and

a second fluid channel operably coupled to each of the inflatable actuators of the second set of inflatable actuators of the actuator assembly and configured to inflate each of the inflatable actuators of the second set of inflatable actuators simultaneously.

14. The actuator assembly of claim 10 , wherein the bottom plate has an axis of symmetry.

15. The actuator assembly of claim 10 , wherein each of the first and second sets of inflatable actuators comprises no more than two inflatable actuators.

16. The actuator assembly of claim 10 , wherein an apex of the V-shaped bottom plate points upward toward at least one solar panel associated with the actuator assembly.

17. The actuator assembly of claim 10 , wherein each of the inflatable actuators comprises a rigid constraint disposed about a peripheral edge of the inflatable actuators.
