System and method for self-contained modular manufacturing device having nested controllers
A system and method for a self-contained modular manufacturing device having self-contained modular tools configured to collectively accomplish a specific task or function in a hierarchical control manner. In an embodiment, the modular device includes a housing that has a mount configured to engage a robotic arm or other form of maneuvering actuator (such a crane or gantry). The housing provides a base by which additional modules may be mounted and coupled. The modular device also includes an interface configured to communicate with a remote master control system capable of control the robotic arm. The modular device also includes one or more other modules that are configured to accomplish a particular task or function. Such modules are sometimes called end-effectors and work in conjunction with each other to accomplish tasks and functions. In a self-contained modular manufacturing device, individual processors disposed in the housing are configured to control the functional tools (e.g., each end-effector) independent of the overall manufacturing control system and pass control of the self-contained modular device between local controllers in a hierarchical manner.
1. A method, comprising:
maneuvering a first self-contained modular manufacturing device to a position to accomplish a first manufacturing function, the maneuvering controlled by a master controller remote from the first self-contained modular manufacturing device;
indicating to the first self-contained modular manufacturing device that the first self-contained modular manufacturing device is in the position;
accomplishing the first manufacturing function, the accomplishing controlled by a first local controller disposed in the first self-contained modular manufacturing device;
maneuvering a second self-contained modular manufacturing device to the first position to accomplish a second manufacturing function, the maneuvering controlled by the first local controller;
indicating to the second self-contained modular manufacturing device that the second self-contained modular manufacturing device is in the position;
accomplishing the second manufacturing function, the accomplishing controlled by a second local controller disposed in the second self-contained modular manufacturing device;
indicating to the first local controller that the second self-contained modular manufacturing device has accomplished the second manufacturing function; and
indicating to the master controller that the first and second self-contained modular manufacturing device has accomplished the second manufacturing function.
2. The method of claim 1 , wherein the position comprises a rough estimate of a final position and wherein the method further comprises relinquishing control of the maneuvering to the first self-contained modular manufacturing device to maneuver the first self-contained modular manufacturing device into the final position with greater precision.
3. The method of claim 1 , further comprising accomplishing the first or second manufacturing task by actuating an end-effector configured to accomplish the manufacturing function.
4. The method of claim 1 , further comprising storing results of accomplishing the first or second manufacturing function in a local memory disposed in the first self-contained modular manufacturing device.
5. The method of claim 1 , further comprising loading parameters for accomplishing the manufacturing function from a local memory disposed in the first self-contained modular manufacturing device prior to accomplishing the first or second manufacturing function.
6. The method of claim 1 , further comprising:
maneuvering the first self-contained modular manufacturing device to a second position to accomplish the first manufacturing function, the maneuvering controlled by the master controller remote from the first self-contained modular manufacturing device;
indicating to the first self-contained modular manufacturing device that the first self-contained modular manufacturing device is in the second position;
accomplishing the first manufacturing function, the accomplishing controlled by the first local controller disposed in the first self-contained modular manufacturing device.
7. The method of claim 1 , further comprising:
maneuvering a third self-contained modular manufacturing device to the first position to accomplish a third manufacturing function, the maneuvering controlled by the second local controller;
indicating to the third self-contained modular manufacturing device that the third self-contained modular manufacturing device is in the position;
accomplishing the third manufacturing function, the accomplishing controlled by a third local controller disposed in the third self-contained modular manufacturing device; and
indicating to the second local controller that the third self-contained modular manufacturing device has accomplished the third manufacturing function.
