A micro grid apparatus and associated method of formation. Multiple tiers are formed. The tiers are distributed and sequenced in a vertical direction such that each tier is at a different vertical level in the vertical direction. Each tier includes a multiplicity of complex shapes interconnected by bridge modules. Each complex shape is a physical structure having an exterior boundary. Each complex shape includes multiple docking bays such that each docking bay is configured to have a module latched therein. Each complex shape is either a power hub including rechargeable batteries or a processor hub including processors. A sensor module is latched in a sensor docking bay and an actuator module is latched in an actuator docking bay of each complex shape in one or more tiers of the multiple tiers.
