The “Smart Home” and the Robot “Butler.”

In Build the Ecosystem, Not Just the Robots. Examples, we suggested the “Robot Butler.”

Creating a single all-purpose household robot may be aiming at the wrong target. The ordinary home contains hundreds, perhaps thousands, of different tasks, many requiring very different physical abilities. A robot that can cook dinner, clean a bathtub, wash windows, mow the lawn, fold laundry, repair a faucet, carry groceries, change a light bulb, and make a bed would require an extraordinary collection of sensors, manipulators, tools, skills, and programming.

Humans accomplish these things with hands, legs, brains and a general understanding of today’s culture, that nature has spent millions of years developing. Reproducing all of those capabilities in one machine may be extraordinarily difficult and, more important, unnecessary.

A simpler approach is to divide the household into specialized functions. Instead of teaching an all-purpose robot to push a vacuum cleaner, build a vacuum cleaner that moves by itself.

Instead of teaching the robot to wash windows, build a specialized window-cleaning machine or incorporate cleaning mechanisms into the windows.

The same principle can apply to lawn care, laundry, food preparation, dishwashing, security, climate control, inventory, deliveries, and dozens of other household functions. Each specialized machine needs to solve only its own relatively narrow problem. This is the principle I described earlier: automate the household rather than the housekeeper.

The general-purpose robot then becomes something quite different. Think of it as the butler robot. It might have wheels, arms, cameras, and manipulators for miscellaneous jobs, but physical labor would not be its primary function.

Its most important job would be to understand what the resident wants and translate those wishes into instructions for the household’s specialized machines.

Tell the butler robot, “Get the house ready for six guests at seven o’clock,” and it might instruct the floor-cleaning robot to vacuum, the food system to prepare dinner, the climate system to adjust the temperature, the lighting system to prepare the dining room, and the lawn machine to finish its work before the guests arrive.

The butler robot would coordinate the jobs, monitor their progress, handle conflicts, and ask the human for a decision when necessary.

We already have a miniature example of this concept: the modern automobile. In that system, the human serves as the butler.

Walk toward the car with the key in your pocket and one specialized system recognizes the key, tells another system to unlock the doors, and may tell still another to turn on the lights.

Press the Start button and a sequence of specialized machines and computers prepares the car to operate. Select reverse and the transmission engages reverse while the backup camera comes on and proximity sensors begin watching for obstacles.

Shift into drive and the camera turns off, the transmission changes its function, and other systems begin monitoring speed, approaching traffic, lane position, engine conditions, tire pressure, and dozens of other variables.

As conditions change, headlights may turn on, windshield wipers may activate, warning signals may sound, and braking or steering systems may intervene.

No single mechanism does all these things. Specialized components perform specialized jobs and exchange information so quickly and routinely that the driver experiences them as one machine: the car.

The automated house would extend essentially the same principle to a much larger and more varied collection of machines, with the robot butler assuming many of the coordinating functions now performed by the automobile’s human driver.

This approach creates another problem, however. The butler and all those specialized machines have to be able to talk to one another. A homeowner should not have to buy every appliance, robot, window, thermostat, security device, and lawn machine from the same corporation. Nor should the manufacturer of the butler robot have to write entirely new software for every product ever introduced by every other manufacturer.

What is needed is a common language—a set of standards allowing machines made by different companies to identify themselves, describe their capabilities, accept instructions, report their status, and communicate problems.

There already is a precedent for exactly this kind of industrial cooperation. The Connectivity Standards Alliance developed Matter, an open smart-home communications standard supported by hundreds of companies. Amazon, Apple, Google, Samsung SmartThings, Signify, and many others participated in its development.

Matter is intended to allow smart-home products from different manufacturers and ecosystems to communicate using a common protocol. Today’s Matter already provides such functions as device discovery, provisioning, secure communications, and control.

The household-robot system I envision would take that principle much further. The objective would not merely be to let the butler turn on a light made by Company A or change the thermostat made by Company B. The standard would allow a machine to tell the entire household system what it is, what it can do, what it needs, what commands it understands, and what information it can return.

Imagine bringing home a new window-cleaning robot made by a company from which you never before have purchased anything. The butler should not require special WindowBot software. The new machine should be able to announce, in effect: “I am a window-cleaning device. I can wash, rinse, dry, and inspect windows. I require electrical power, water, cleaning fluid, and access to the window. I accept commands to start, stop, pause, resume, inspect, clean a specified area, and return to my storage location. I can report my location, progress, supply levels, equipment condition, problems, and completion.”

If both machines conform to the standard, the butler robot already knows how to employ its new worker.

Creating such standards would require cooperation among companies that normally compete with one another. A House-Robot Committee could begin with companies that already possess pieces of the necessary technology. Amazon, Apple, Google, Samsung, and perhaps OpenAI could contribute artificial intelligence, speech, vision, operating systems, and home-control expertise.

Indeed, Amazon Echo, Google Nest Hub, Apple HomePod, and Samsung SmartThings already can function as hubs for Matter devices.

Companies specializing in household robotics could provide another part of the expertise. iRobot and Roborock, for example, have experience with autonomous navigation, mapping, docking, obstacle avoidance, and specialized cleaning machines.

Appliance manufacturers such as Whirlpool, LG, Bosch, and Samsung could represent refrigerators, ovens, dishwashers, washers, dryers, and other stationary machines—which really are specialized robots whether or not we call them robots.

Building-system companies also would be essential. Schneider Electric could contribute expertise in electrical and energy-management systems; Honeywell in environmental controls and sensors; Signify in lighting; and companies specializing in locks, doors, windows, plumbing, security, and building materials could represent the increasingly automated structure itself.

Husqvarna and similar companies could represent robotic lawn and outdoor equipment. NVIDIA and semiconductor manufacturers could contribute the processors, sensors, communications hardware, and artificial-intelligence infrastructure on which the entire network would depend.

Many companies in these categories already participate in the Connectivity Standards Alliance, demonstrating that cooperation among otherwise competing manufacturers is quite practical.

The committee should not try to standardize the robots themselves. That could inhibit innovation. A company should remain free to invent a better window cleaner, another a radically different food-preparation system, and another a lawn machine nobody previously imagined.

What should be standardized are the interfaces among them: how machines describe their capabilities, how tasks are requested, how permissions are granted, how priorities are established, how status is reported, how errors are communicated, and how one machine discovers what another machine can do.

This also changes the economics of household robotics. No corporation has to solve the entire almost impossibly difficult problem of building an artificial human. Hundreds of companies can solve smaller problems at which they already have expertise.

A refrigerator company improves refrigerators. A window company improves windows. A robotics company improves mobile machines. An AI company improves the butler’s ability to understand people and coordinate machines. Improvements can be introduced one component at a time without replacing the entire system.

The result ultimately may make the distinction between the robot and the house increasingly meaningless. The mobile butler is merely the human’s principal representative within a network of specialized machines, sensors, appliances, computers, and structural systems.

Intelligence and physical capability are distributed throughout the house. One machine does not have to know how to do everything because the system knows which machine can do each thing. Further, the failure of one  machine would not require replacing the entire system, nor would it disrupt the entire system. The faulty part simply could be identified and replaced.

In that sense, the most important household robot of the future may not be a robot at all. It may be the house itself—a modular robot consisting of hundreds of specialized components, coordinated by an intelligent butler that understands what its human residents want. When the car  radio goes down, the car doesn’t stop. You just replace the radio.

The first step toward building it may therefore have surprisingly little to do with building robots. The first step may be getting the companies that eventually will build all those pieces into the same room and agreeing on how their machines will talk to one another.
