A network of modular, multitier mobile units that are each capable of collecting data for processing as a user uses them in their residence or business premises performing a task or a chore, or as they move about within an area in a property based on their mobility capabilities and current location. The modular, multitier mobile units are designed including NFC or other near or full contact pads on which emitters and/or sensor units and/or other robot mechanical/electrical units can be docked and powered without requiring connectors. The modular, multitier mobile unit networks are designed to function in many different tiers, such as tier zero node, tier one node, tier two node and tier three cloud node, each having capabilities to process the collected data. The modular, multitier mobile units are capable of sharing the collected data and resources with each other. The tier three cloud node provides additional processing power that does not exist in lower level tiers and also provides artificial intelligence, voice recognition and synthesis, face recognition capabilities.
