Lumen 55′′

Lumen is a robot with a transparent screen you can see the room through, and it drives itself. It stands as tall as an adult, speaks 60 languages and does not point visitors in a direction, it walks them there. We install it, fill it with your content and stay responsible for it.

A transparent screen at eye level, a life-size avatar and movement through the room. Where a poster or a fixed screen fails because nobody looks twice, this robot stops people.

Visitors ask anything, by voice or by touch, and get the answer in their own language. Never away from the desk, never tired. It replaces the info point that stands empty most of the day.

02 · Where it works

  1. 01

    Among the shelves in a shop

    It takes a shopper to the product they are looking for and tells them along the way what is on offer this week. A category from your catalogue is mapped to a point in the space.

  2. 02

    A shopping centre

    On the transparent screen it shows a map and the way to a shop, and the visitor sees the space behind it rather than a black panel. Alongside the wayfinding, the centre operator content runs.

  3. 03

    A hotel reception

    It greets guests in the language it hears, gives the pool and restaurant hours and walks them to the lift. The night shift is no longer left without someone to ask.

    Hospitality and hotels

  4. 04

    A fair or showroom

    It stops passers by because it moves and speaks, and answers a question before the exhibitor arrives. We change the content on the screen remotely, during the day too.

  5. 05

    A public building or information point

    It directs people to a counter or a department and answers in the visitor language, including a foreign one. What it says is put together in advance and can be attached to tender documents.

03 · Why this robot

Category Lumen

  1. 01Presence you cannot walk pastA transparent screen at eye level, a life-size avatar and movement through the room. Where a poster or a fixed screen fails because nobody looks twice, this robot stops people.
  2. 02A guide in 60 languages at onceVisitors ask anything, by voice or by touch, and get the answer in their own language. Never away from the desk, never tired. It replaces the info point that stands empty most of the day.
  3. 03It does not point, it leads"Take me to shop X" and the robot walks ahead of the visitor to the spot. No more standing in front of a floor plan on the wall. It drives without floor markers, avoids obstacles on its own and returns to the charger.
  4. 04Advertising space that movesThe transparent screen is advertising space that goes where the people are. Messages change through the day, the avatar takes on the tone of the campaign, and what is shown is tied to the hour and to the spot in the room.
  5. 05Insight a fixed screen cannot giveThe robot records what people ask and where they go, anonymously and in aggregate. That shows what visitors cannot find, where the crowding is and whether a campaign worked.
  6. 06EU by designVoice and data processing stay in the EU. In our installation the robot does not recognise faces. For public institutions, healthcare and tender documents that is a requirement, not an extra.
  7. 07We install it and we stayDelivery, mapping the space, content, staff training and support are ours. We do not sell the robot and leave: it stays connected to our platform and we stay responsible for it.

Works the whole opening time. When it gets quieter, it returns to the charging station by itself, and is back before you need it again. The robot complements your staff, it never replaces them.

Who it is for

Retail

Entrance and promo island, where the message changes during the day and there is no time to print.

Shopping centres

Shared floors, where the screen walks a visitor to the unit and does not block the path.

Fairs and events

A stand where people stop at a screen you can see straight through.

Frequent questions

Does the robot need floor markers or changes to the space?

No. We map the space with a laser rangefinder and the robot drives from the map that comes out of it. No floor markers and no building work. It needs a charging station with a socket and a clear path to it.

What happens when somebody steps in front of it?

It stops and waits, then recalculates the route. It drives at 0.3 to 1 metre per second, slower than walking, and among people it stops often. That is deliberate.

Does it record visitors or recognise faces?

In our installation the robot does not recognise faces. Questions and routes are recorded anonymously and in aggregate, and processing stays in the EU.

Who prepares the content the robot talks about?

We do. From you we need what you already have: a floor plan, a list of shops or services, opening hours and frequent questions. We build the content from that and review it with you before the robot goes out.

How long from order to a robot that works?

Usually a few weeks. Mapping the space and preparing the content take the most time, not delivery.
