Abstract

Exemplary embodiments relate to applications for soft robotic actuators in the manufacturing, packaging, and food preparation industries, among others. Methods and systems are disclosed for packaging target objects using soft robotic actuators, for moving and positioning target objects and/or receptacles, and/or for diverting or sorting objects. By using soft robotic actuators to perform the fixing, positioning, and/or diverting, objects of different sizes and configurations may be manipulated on the same processing line, without the need to reconfigure the line or install new hardware when a new object is received.

First claim

The invention claimed is:

1. A system comprising:
a moving surface for carrying a target object;
a soft robotic actuator in proximity to the moving surface, the soft robotic actuator comprising a compliant or flexible body having a reservoir and configured to be inflated by supplying an inflation fluid to the reservoir; and
a controller unit, adjacent to the moving surface, to couple in a fluid-tight seal with the reservoir of the soft robotic actuator when the soft robotic actuator moves into proximity with the controller unit and cause a change in state of the soft robotic actuator via the coupling.

2. The system of claim 1 , wherein the soft robotic actuator is movable and the controller unit is stationary.

3. The system of claim 2 , wherein the soft robotic actuator is coupled to the moving surface.

4. The system of claim 1 , wherein the controller unit is movable and the soft robotic actuator is stationary.

5. The system of claim 1 , wherein the controller unit is movable and the soft robotic actuator is movable.

6. The system of claim 1 , wherein the change in state comprises: causing the inflation fluid to be delivered to the soft robotic actuator.

7. The system of claim 1 , wherein the change in state comprises: causing the inflation fluid to be removed from the soft robotic actuator.

8. The system of claim 1 , the controller unit further to cause a second change in state of the soft robotic actuator when the soft robotic actuator moves away from the controller unit.

9. The system of claim 1 , the controller unit further configured to cause a change in state when the soft robotic actuator approaches or departs the controller unit through the use of wireless signals.

10. The system of claim 1 , wherein the change of state causes the target object to be moved from a first location to a second location.

11. The system of claim 1 , wherein the change of state causes the target object to be released at a fixed rate.

12. The system of claim 1 , wherein the change of state causes the target object to be released at a variable rate.

13. The system of claim 1 , wherein the change of state causes the target object to be fixed in place.

14. The system of claim 1 , wherein the soft robotic actuator is a linearly-extending actuator.
