A home robot you can teach.

A personal teachable assistive robot. Say what you want, show it, or point. When unsure, it asks. Then it remembers.

  • Two arms with grippers
  • A little bigger than a robot vacuum
  • Talks and listens in plain language
  • Weighs less than a toddler
  • Based on trustworthy AI methods
  • Built in Vienna
AhaRo: a slim wheeled base, a tall column carrying two small arms with grippers, and a camera head on top. One arm reaches toward the viewer.

Your robot does not need to work everywhere. It needs to work at your place.

Instead of learning a general solution, we provide a general learning method for user-specific solutions. Taught its own home and the tasks that matter to you, by the people who live there.

Most robots are built to

  • work in any home, on paper
  • learn from huge datasets
  • carry on when something has moved
  • do one step, then lose the thread
  • do things one standard way

AhaRo is built to

  • do your tasks well
  • learn from a few demonstrations
  • notice when something has changed, and ask
  • combine skills into new tasks
  • do things your way, and remember it

Show it once.

All in plain language: no app, nothing to program. You talk to AhaRo as you would to a helper, and it talks back. Teaching is not setup. It is everyday use, and it gets shorter each time.

YouThis is my home. Here is the fridge, and this is how you open it.

Skills it has learned

  • cups, bottles, cloths, the things that end up on the floor
  • the cloth, the fruit bowl, your glasses, wherever they were last
  • yours needs a firm pull, then it swings
  • the bedroom door swings, the balcony door slides
  • on its own, when the battery runs low

New capabilities, no new lesson

  • find the cloth, bring it, take the cup to the sink
  • open the fridge, pick up the juice, open the balcony door, bring it out
  • pick up the cups, put them by the sink, dock
  • find it where it saw it last, pick it up, bring it
  • checks what it saw this morning and answers. And at 13:00, unasked: here are your pills for one o'clock

Built for a home, not a factory.

Light enough to lift into a car, slim enough for any doorway. Sized for a flat, not a production line.

  • A depth camera sees the room, the objects in it, and your gestures. When you point, it works out what you mean.

  • Lightweight arms with two-finger grippers, sized for cups, bottles, handles and switches. They give way if they meet something unexpected.

  • Both arms ride the column, so AhaRo reaches a remote on the floor and a cup on the counter.

  • A little bigger than a robot vacuum. Carries the computer and battery on two drive wheels and casters, low to the ground.

Weighs less than a toddler. Images are renders; photos and specifications will follow.

What it does at home.

Everyday abilities to start with, more as you teach it. You ask in plain language; it answers the same way.

  • Brings what you name or point at. Bring me my glasses.

  • Everyday speech. Asks back when unclear, tells you what it is about to do.

  • Learns your layout and moves between rooms on its own.

  • Picks up, places, tidies, puts away.

  • It goes and looks, then tells you. Where did I leave the keys?

  • Medication, meals, appointments. Brings what the reminder is about.

  • Swinging or sliding, once it knows which is which.

  • Which pot, how much, how often, once you have shown it.

  • Fills the bowl on schedule, throws the ball when you are out.

  • Ask from anywhere, it goes to look. Is the stove off?

  • Docks on its own when the battery runs low.

  • Someone you choose sees what was done, adjusts the schedule, and steps in from their phone when asked.

Who it is for.

  • An extra pair of hands for reaching, carrying and remembering, without giving up your own place.

  • There between your visits, and tells you what happened.

  • Bowl filled, ball thrown, plants watered, on schedule, and the home looked after while you are away.

  • Taught once per resident's room and routine; takes the small errands off staff rounds.

From passive to active intellect.

Today's robot AI recognises and imitates well. It does not know when it is unsure, and it does not plan past the next step. AhaRo adds the proactive part: knowing how sure it is, deciding when to ask, and reasoning about the whole task.

Where most robot AI stops

  • it has read a lot
  • it can tell a cup from a bottle
  • it can copy a movement
  • it has a rough idea how things move

Where AhaRo starts

  • it knows when it is unsure
  • it knows when to hand over to you
  • it learns from you as you go
  • it thinks a task through before acting

A hybrid cognitive architecture, neuro-symbolic in research terms. Learned skills give it a feel for the physical world. A step-by-step planner chains them into longer tasks, with repeats and fallbacks. A memory of your home holds where things are, how they work and how you like them handled.

Every skill knows how confident it is. When confidence drops, AhaRo stops and hands the decision to you, or to someone you trust, from wherever they are. Nothing happens on a guess.

More than five years of robot learning research at TU Delft and RWTH Aachen. Key parts of the system are the subject of patent applications.

Pilot with us.

AhaRo is not for sale yet. We are shaping it with pioneer customers in Vienna, around real homes and routines. Status: working prototype, first pilots in preparation with care providers.

  • Ask us to keep you posted; we write when there is something to show.

  • Tell us about your home and the tasks you would hand over first. Some households try AhaRo remotely; a few host it at home, with our engineers alongside.

  • A few providers in Vienna to run AhaRo in a resident's room or on a care round, with our team on site.

  • The same address reaches the founder directly.
