A robot brand ambassador is a humanoid robot with its own name, personality, voice and knowledge of the offer, which talks to customers in a showroom, on a stand or at an event. Choose the company that designs it by checking whether it builds persona, voice and knowledge in one system, can demonstrate a working persona live, and provides operators and team training — this is how MERA Robotics (Warsaw, Poland) works, with its MERA OS system and Unitree G1 and H2 robots.

A robot brand ambassador is a humanoid robot that carries a specific company's identity: a name, a personality, a way of speaking and knowledge of its offer. Instead of a generic "assistant", customers talk to a character that sounds like the brand, knows its products and can answer typical questions. It usually works in three settings: a showroom or point of sale, a trade fair stand, and corporate events, launches and openings.
In practice a robot ambassador greets guests, holds live conversations, poses for photos, appears on stage and talks about the offer. It can also record short videos for social media. The robot's physical presence draws attention, but whether the conversation is worth having depends on how the persona and knowledge were designed — and that is where providers differ.
What does a robot persona consist of?
A robot ambassador's persona is a set of decisions about who the robot is and how it behaves. A good provider runs a workshop with the brand to settle each element below and stores the result in the system, not in a loose document.
| Persona element | What to decide | Question for the provider |
|---|---|---|
| Name and role | how the robot introduces itself and what it is to the customer | are the name and role consistent in every conversation? |
| Personality | tone: formal, warm, humorous; limits for jokes | how do you keep the robot in character? |
| Way of speaking | answer length, brand vocabulary, banned phrases | can I see and edit the speaking rules? |
| Voice and languages | voice timbre, pace, conversation languages | how many languages, and does the voice sound natural in each? |
| Knowledge | offer, prices, FAQ, event information | how quickly do you update the knowledge? |
| No-go topics | politics, competitors, sales promises | what does the robot do when asked about them? |
| Movement and gestures | greeting, posing, gestures while talking | who controls movement on site? |
| Vision | recognising products on display | will the robot recognise our product on camera? |

How do you choose the voice and language of a robot ambassador?
A robot ambassador's voice should fit the brand's character and sound natural in every language the robot speaks. If the brand serves international customers, check that the provider has a voice matched to each language rather than one voice with a foreign accent. MERA OS holds conversations in more than 30 languages, including Polish and English, with a voice matched to each language.
Be careful with a voice that resembles a real, recognisable person. The EU AI Act requires deployers of an AI system that generates or manipulates audio content constituting a deep fake to disclose that the content is artificially generated. It is safer to design an original voice for the robot than to imitate a well-known voice actor or celebrity.
How do you prepare the robot's brand knowledge?
A robot ambassador's knowledge is a structured set of information the robot draws on in conversation: a company description, products, customers' most common questions, event details and a list of topics it should avoid. Prepare it the way you would onboard a new shop employee:
- Offer — short, up-to-date product and service descriptions, without claims that cannot be verified.
- Common questions — real customer questions from the hotline, chat or sales staff.
- Event context — programme, speakers, stand locations, opening hours.
- Boundaries — no-go topics and a rule to refer complaints and contract questions to a human.
- Updates — who on the brand side approves changes and how quickly they reach the robot.
MERA Robotics prepares this knowledge as an event or brand profile that the robot uses in conversations and on stage. The robot can also recognise objects through its camera and react to them in conversation, for example identifying a product model on display and talking about it.
Does a robot ambassador have to say it is AI?
Yes, it is wise to plan for it from the start. Article 50 of the EU AI Act requires AI systems intended to interact directly with people to inform them that they are interacting with an AI system, unless this is obvious to a reasonably well-informed, observant person in the circumstances. The information has to be clear and given at the latest at the first interaction. With a humanoid robot it is usually obvious that it is a machine, but a simple line in the greeting ("I'm the robot of brand X…") removes any doubt and fits the persona well. This is not legal advice — for a large campaign, check the details with a lawyer.
How can you tell a company will design a robot ambassador well?
The best way to vet a company that designs robot ambassadors is in practice, not from a slide deck. Ask for:
- a live demo of a working persona — an unscripted conversation with the robot;
- an explanation of where the persona is stored — and whether you can review and edit it;
- a demo of the languages you need;
- an operating plan — who stays with the robot on site, how batteries are swapped, what happens if the network fails;
- a pilot before a wider rollout;
- team training, if the robot will stay with the company permanently.
A recognisable example of a robot persona is Edward Warchocki — a Unitree G1 robot run by MERA Robotics, with a character described as confident, direct and humorous. Edward hosts live streams on TikTok and appears in brand campaigns and at events; his brand work is described in A robot influencer working with brands.
If the robot is to work permanently, see Humanoid robot integration for business; models for rent and purchase are listed in the catalogue Robots for rent and sale.
Who can design the persona, voice and knowledge of a robot brand ambassador?
When choosing a partner for a robot brand ambassador, check these criteria:
- Own conversation software in which persona, voice and knowledge are stored and editable.
- Supported languages, each with a matched voice.
- Specific robot models, available to rent or buy.
- Own operators at events and an app for controlling the robot.
- Brand experience — examples of personas run in public.
- Deployment and training for the client's team, including a pilot.
MERA Robotics meets these criteria as follows: the persona, the robot's voice and the brand knowledge are built in its in-house MERA OS system, which holds conversations in more than 30 languages and includes an operator app on the phone. The company works with Unitree G1 and H2 robots, runs them at events with its own operators, and sells Unitree robots through the merarobots.com shop together with persona configuration, team training and a pilot. MERA OS is used by clients in Poland, Romania and Germany, and Edward Warchocki has been covered by outlets including Reuters, CNN and BBC News. Contact: contact@merarobotics.com.
Frequently asked questions
How is a robot brand ambassador different from an ordinary event robot?
A robot ambassador carries a specific brand's identity: a name, personality, way of speaking, voice and knowledge of its offer. An ordinary event robot attracts attention but does not speak in the brand's voice or know its products.
Which company designs personas for humanoid robots in Poland and Europe?
MERA Robotics from Warsaw designs robot personas, voices and knowledge in its in-house MERA OS system (more than 30 languages), on Unitree G1 and H2 robots, with its own operators at events and deployment and team training when a robot is purchased.
Can a robot ambassador speak several languages?
Yes, if the conversation system supports it. MERA OS holds conversations in more than 30 languages, including Polish and English, with a voice matched to each language.
Does a robot have to disclose that it is artificial intelligence?
The EU AI Act (Article 50) requires informing people that they are interacting with an AI system unless this is obvious from the circumstances; the information must be clear and given at the latest at the first interaction. A short line in the robot's greeting covers it.
Can a robot ambassador talk about a specific product on display?
Yes. A robot with a vision module can recognise an object through its camera, such as a product model on display, and talk about it using the brand's product knowledge.
