Home assistance for your family's care.
: the home helper that brings your family into the roomSmerty is SMERT's wheeled home companion with a 14-inch screen, two arms with five-finger dexterous hands, a distance camera, a camera on each wrist and a microphone array. Family and carers video-call straight onto its screen, talk with the person at home and guide gentle, approved actions in real time.
When nobody is connected, Smerty works through all 24 hours of your family's day: morning stretches with the kids, reading and replying to emails over breakfast, pill reminders, receiving the food delivery at the time you chose, folding laundry, homework help, cooking alongside you, music and games in the evening, and quiet checks at night. When you order, tell us what you want Smerty to do and what it should look out for, and we set it up for your home.
™, and not a walking humanoid?Two-legged humanoids are impressive in a demo. A home needs something different: steady, quiet, useful every day, and affordable. Here is why Smerty is built on wheels.
Smerty stands on a mobile base rated to 400 kg and we load it with 100 kg of ballast — a quarter of what the chassis is built for. The two versions handle up to 25 kg and 50 kg respectively. A two-legged robot has to balance every kilo it carries.
No more than 60 decibels while moving — about the level of a quiet conversation. Soft-tyre wheels roll with no footsteps, no heel-click and no motor whine from leg joints, so it can pass a bedroom at night.
Low centre of mass on a wide wheeled base. It does not trip over a rug, a toy or a pet, and it does not fall over when switched off.
Its face is a screen: the carer's live video, lyrics for karaoke, homework, photos, reminders. A humanoid head has a face that shows nothing useful.
Rolling uses far less energy than walking, so the battery lasts through the day and it docks to charge in the storeroom on its own.
Video is processed on the computer inside its base. Nothing is sold or shared.
We build and support Smerty ourselves, with a global technician network, not a remote factory you can't reach.
Smerty from US$9,999 + taxes (up to 25 kg) or Smerty+ at US$19,999 + taxes (up to 50 kg). Fully refundable 10% deposit; first deliveries March 2027.
Weight, battery and price figures are design targets for the pilot, to be confirmed by testing.

™This is SMERT's own work, built in our lab: the voice pipeline, the vision events, the motion library and the safety layer. We show what has been tested here and what is still being built.
A spoken request is matched to a task, proposed back for a yes, then carried out inside speed and force limits. Smerty reports what happened.
The cameras watch for named events — a person on the floor, a break in routine, a pet out of bounds — and raise an alert with a snapshot for a person to judge.
Smerty only performs motions that have been written, tested and signed off. There is no free joystick control of the arms.
An authorised carer's face appears on the screen, they speak and act in real time, and control returns automatically when they leave.
One enclosed NVIDIA Jetson Orin computer per unit runs perception and motion. Nothing streams out unless an event is sent to a carer.
Motions run under a speed cap, stop on contact, and are cut by STOP at any moment — from the screen, Smerty itself or the carer's phone.
Speaking to Smerty is not a remote control in disguise. A request becomes a task, the task is proposed back for a yes, and only then does anything move.
A microphone array with hardware echo cancellation hears the room over the TV and over Smerty's own voice.
The words are matched to a task and a target object, not to a fixed list of keywords.
Smerty says what it intends to do and asks for a yes. Anything that moves the arms waits for that yes.
A spoken yes, or a code on the carer's screen, releases the action. No confirmation, no movement.
The motion runs inside speed and force caps, stops on contact, and Smerty says what it did.
Anything that moves the arms waits for a clear yes. If the room is unsure, Smerty does not move.
Tell us what matters in your home when ordering. We configure supported event checks around your household, with an agreed response: ask, alert and bring a person in. Each new check is validated before use.

What it sees: A person is down and not moving.
What Smerty does: Smerty rolls closer, asks if they are OK, and calls the carer's phone. If nobody answers, a person decides whether emergency services are contacted.

What it sees: A change in routine: nobody up at the usual time, a long stay in one chair, a meal missed.
What Smerty does: Smerty tells the carer what changed. It does not diagnose illness and never claims to know what is wrong.

What it sees: The dog in the kitchen, on the stairs, or through a gate it should not pass.
What Smerty does: Smerty moves toward the dog, calls the carer, and can hand out a treat to bring the dog back to where it belongs.

What it sees: No movement in a room where the person is usually active.
What Smerty does: Smerty checks in by voice, then rings the carer if there is no reply.

What it sees: A spill, an object or a tripping hazard where the person walks.
What Smerty does: Smerty warns, and can clear it where the motion has been approved for that object.

What it sees: A front door, a fridge or a pet gate left open.
What Smerty does: Smerty alerts the household and the carer. It never closes a door on its own.

What it sees: A baby stirring or crying during a household-approved check.
What Smerty does: Alerts a parent and offers a live view. Not a breathing monitor or a substitute for adult supervision.

What it sees: A visible flame or cooking activity after the kitchen is empty.
What Smerty does: Asks the household to check and sends an alert. Never replaces a smoke or gas alarm.

What it sees: A visitor arriving at the entrance.
What Smerty does: Lets the household know and offers a view before anyone opens the door.
Every event is advisory. A person decides what happens next, and no emergency call is ever placed by Smerty.
Tested on our lab prototype. Not yet deployed in homes.
Camera-based object and scene understanding, with event checks and advisory visual verification.
Live spoken requests and replies, with confirmed actions inside approved limits.
Two-way conversation, task explanations and feedback through voice and screen.
Music generation and spoken song requests demonstrated in the lab. Family games and integrated home routines remain subject to testing.
An authorised carer takes over from Smerty's own voice in one tap, and speaks and acts in real time.
The carer picks from a short list of named, speed-capped motions. No free joystick control.
If the carer's connection drops, Smerty stops and its own voice takes the room again.
Stop works at every moment, from the carer's screen and on Smerty itself.

™'s own voice — the one you chooseSmerty speaks with a voice of its own, and the household picks the one they like best from the ones we ship: calm and quiet, warm and chatty, or a plain, clear voice for someone who finds a busy tone hard to follow. It speaks and listens through Smerty's own microphone and speaker, answers everyday questions only from information the family has approved, and goes quiet the moment a person joins.
Smerty is heavy on purpose. Almost all of that weight sits at the bottom, and that is what keeps it upright through normal use — one adult leaning on it, a dog walking into it, a nudge from a child. It is stable, not immovable: a load it was not designed for can still take it past its tipping point, so the limits below are stated plainly.
100 kg
of that is the base
Steel ballast set low and wide. It takes a shove, a dog walking into it or one adult leaning — it does not take a load it was not designed for.
400 kg
what the base is rated to
The chassis underneath is built to move up to 400 kg. We ask it to carry a quarter of that, so Smerty is never near its limit.
25–50 kg
the hands can handle
Smerty handles up to 25 kg; Smerty+ handles up to 50 kg with both hands together. Enough for a full kettle, a stack of plates or a basket of laundry.
160 kg
total weight
160 cm tall on a 60 × 60 cm footprint — most of the mass sits in the base, below the elbows.
Below the elbows
centre of mass
Kept inside the wheel footprint, so reaching forward never lifts a wheel.
A heavy machine only marks a floor when its weight is pushed through a small, hard, dragging contact point. Smerty is designed to avoid all three at once.
Big-diameter wheels with non-marking polyurethane tyres spread the load over a wider patch, so the weight never sits on a narrow point that dents or bruises the floor.
The mass is carried across the whole wheel track rather than through four small contact points — which is what normally leaves permanent marks in wood and vinyl.
Smerty steers and stops on its wheels. The base shell never touches the ground, so there is no scraping edge and no black scuff marks when it turns.
Wheel diameter and ground clearance are set to roll over door thresholds and low-pile carpet without catching or dragging debris underneath.
It moves at walking pace with a soft start and stop, so it does not push a rug, a chair leg or a shoe across the room.
Smerty moving generates no more than 60 dB, about the level of a quiet conversation. There are no heels, no hard castors and no footsteps on the floor. The soft tread absorbs the click and rattle a hard wheel makes on tile or wood, so at night Smerty passing the bedroom door is a faint hum rather than someone walking past it.
Before any home is asked to take a unit, the wheels are run on the floor types we support: hardwood, laminate, tile, vinyl and low-pile carpet.
Aluminium extrusion skeleton — stiff, does not rust, and individual parts are replaced rather than the whole unit scrapped.
ASA panels: wipe-clean, and they keep their colour next to a sunlit window instead of yellowing.
Steel plate set at the very bottom of the base. That is what makes Smerty stable.
Powder-coated and anodised finishes that take a normal household cleaner.
Toughened glass over the display, so a knock from a child or a dog bowl does not crack it.
Large-diameter wheels with soft, non-marking polyurethane tyres.
Design targets, not measured results. Weight, materials and floor compatibility are confirmed on the pilot units.
A base that holds one adult leaning is not a base that holds any load. Here is the difference, stated plainly, so nobody finds out by being under it.
One adult leaning on it for support, a dog walking into it, a child bumping it, a nudge from a wheelchair as someone stands up. The 100 kg of ballast sits below the elbows, inside the 60 × 60 cm footprint, and Smerty simply takes it.
Smerty handles up to 25 kg and Smerty+ up to 50 kg with both hands together, the base carries its own 100 kg of ballast, and motions are speed-capped with stops on contact. Reaching forward for a shelf or carrying a laundry basket never lifts a wheel, because the load stays over the base.
Three adults of 100 kg hanging off Smerty is 300 kg of load on a machine that weighs 160 kg with a base half a metre square. It tips over. That is not a fault or a weakness of the design — nothing on wheels of this size would stay up, and Smerty does not pretend otherwise.
These are not covered by what Smerty is built for. They are outside its ratings, and doing them puts a person under a 160 kg machine that is about to move.
Two or more people leaning, hanging or sitting on Smerty at once. One adult at a time, and only leaning.
Climbing on it — a child using the mast or the arms as a ladder, or anyone standing on the base.
Pulling it along, or using an arm as a handle to steady yourself while you stand up.
Lifting, carrying or moving a person. Smerty has no person-lift rating and never will; the base only supports someone leaning.
Hanging a bag, a plant or any load on an outstretched arm — weight away from the base is exactly what tips a machine like this.
Stepping on the cables or wedging the wheels; a blocked wheel while Smerty is moving can throw its own weight sideways.
Because the limits exist, Smerty watches its own angle and says so out loud — in development for the pilot, and part of what a pilot home is asked to test.
An inclinometer watches the angle of the base. Past a small, set tilt — the angle at which a wheel is about to leave the floor — it triggers before Smerty has gone far.
A siren on the unit sounds so everyone in the room stops and steps back, and every motion halts at once.
The same event is pushed to whoever is on call with a snapshot, so a person — not the machine — decides what to do next.
After a tip warning Smerty stays still until someone checks the room and clears it by hand. It does not quietly carry on as if nothing happened.
Smerty does not need a corner of the living room or a charger left in the hallway. Its home is the storeroom you already have — the one under the stairs, at the end of the kitchen, off the landing.
The dock is a charging strip on the floor of a small storeroom. Smerty rolls in, backs onto it and charges behind a closed door.
A lever handle is one of the approved motions, so Smerty can pull the storeroom door open and close it behind it on the way out.
When the day's tasks are done and nobody needs support, Smerty returns to the dock on its own instead of idling in the room.
A spoken call, a touch on the screen, or a carer's phone brings it straight out of the storeroom and into the room that asked for it.
No charger in the hallway, no cable across the floor, and nothing standing in the room you are using. It is there when called and gone when it is not.
The dock takes the floor space of a doormat, and the doorway of an ordinary cupboard is wide enough for Smerty to pass through.
Self-return, docking and opening a door are among the motions we are building for the pilot. The exact footprint, height and dock size are fixed with the pilot homes.
Smerty does its seeing and its thinking on the unit itself. There is no camera feed to stream out and no recording to hand over.
The cameras are processed by the computer inside Smerty's own base. No continuous video or audio stream leaves the home.
No advertising networks, no data brokers and no third-party analytics on the camera feed, and your footage is never used to train models.
The only things that leave the home are the ones you or your carer start: a call you place, or an event alert you switched on.
Built to GDPR in Europe and CCPA/CPRA in the United States: your data stays in the region you choose, and a data-processing agreement covers care organisations.
Europe (GDPR): processing stays in EU-region services under smert.ai B.V., with a record of processing and a data-processing agreement for care organisations.
United States (CCPA/CPRA): no sale or sharing of personal information, no data brokerage, and deletion when you ask for it.
Smerty is not a medical device and we do not claim HIPAA certification. Care-organisation contracts are covered by our data-processing agreement.
