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.
