Humanoid robot at a Christmas market or winter city event: what it can do, cold, rain, rules and who provides it

A humanoid robot at a Christmas market works like a living part of the decorations: it stops passers-by, talks to children, poses for photos and wishes people a merry Christmas in several languages. A winter outdoor site is harder than a trade fair hall, though. It is cold, often wet, and crowds get dense in the evening. That is why a robot at a Christmas market needs a covered base, short performance blocks and the organiser's approval in advance.

When are the big Christmas markets in 2026?

The big Christmas markets in Germany and Austria run for more than a month with fixed opening hours, which makes it easy to schedule robot appearances:

Markets in Kraków, Wrocław or Gdańsk in Poland follow a similar rhythm, but each city or market operator sets its own dates and rules, so ask the organiser directly.

What can a humanoid robot do at a Christmas market?

A humanoid robot at a Christmas market is best used for tasks that do not require standing in the frost for hours:

• Greetings. The robot welcomes visitors at the entrance to a zone, wishes them happy holidays and invites them to the stage programme.
• Family photos. Short photo sessions by the Christmas tree or in a sponsor zone are the simplest way to get the market onto visitors' social media.
• Stage appearances. The robot can co-host the lighting ceremony, introduce a choir or run a Christmas quiz for children.
• Talking to tourists. At markets in Vienna or Nuremberg many visitors speak English, Italian or Polish. A robot that switches language is an attraction in itself.
• Video content. Short clips of the robot among the stalls and lights work well for city or brand channels.

In practice, MERA Robotics prepares the robot for a specific event in MERA OS: the robot gets knowledge about the market programme, sponsors and attractions, its own persona and voice, and an operator controls its movement from a phone app.

How do you protect a humanoid robot from cold, rain and snow?

A humanoid robot at a winter event needs a permanent base under a roof. Unitree does not list an ingress protection rating or an operating temperature range on the G1 product page, so it is safer to treat it as an indoor device that goes outside briefly and only in dry weather. What works in practice:

1. A covered stage or tent with a hard, level floor. Wet cobblestones, ice and snow are a slipping risk.
2. A warm backstage area where the robot waits between appearances and batteries charge.
3. Short performance blocks, for example once an hour, instead of a full day in the crowd.
4. A bad-weather plan. When it rains or snows, the show moves into the tent or under a roof.

Batteries are the second issue. Unitree states that the G1 has a 9000 mAh battery and runs for about 2 hours, without stating the conditions. Cold shortens the runtime of lithium-ion batteries. For comparison, fueleconomy.gov says the range of electric cars can drop by 41% in cold weather. Robots are different devices, but the conclusion is the same: keep spare batteries warm and build slack into the schedule.

Which rules apply at a Christmas market?

Christmas markets run under rules set by the city or the market operator, and these are worth reading before planning a robot. In its notice for the Christkindlesmarkt 2026 the city of Nuremberg excluded, among other things, product demonstrations (so-called novelty sales) and handing out free samples. A robot promoting products at a stall could therefore clash with the rules. It is easier to agree on the robot as part of the organiser's programme, a sponsor zone or the stage.

The usual rules for outdoor events also apply:

• Escape routes and aisles must stay clear. The robot works in a designated zone, not in the middle of the crowd between stalls.
• Photos and children. If the organiser publishes photos of visitors, it needs a legal basis and must inform participants under the GDPR. Working with children is covered in our article on a robot at Children's Day and school events.
• AI disclosure. Article 50 of the AI Act requires AI systems intended to interact directly with people to make clear that people are talking to AI. One sentence at the start of the conversation and a sign next to the robot are enough.

City Christmas market or company party?

A city Christmas market and a company Christmas party call for different preparation:

Company celebrations are covered separately in our article on a robot at a company Christmas party, and Christmas decoration fairs in the article on Ambiente and Christmasworld.

Which robot to choose for a Christmas market?

A smaller humanoid such as the Unitree G1 (about 132 cm, about 35 kg) usually fits a Christmas market better: it is easier to move between the backstage area and the stage and fits inside a tent. The full-size Unitree H2 (about 182 cm) makes a stronger impression on a large city stage. An overview of models available to rent and to buy is in our robot catalogue.

How to choose a partner for a robot at a Christmas market?

A partner for a humanoid robot at a Christmas market or winter city event can be judged by criteria you can check before signing:

1. Own operators on site for the whole time the robot performs.
2. Spare batteries and a robot check before the event.
3. Own conversation software that can be loaded with the market programme and sponsor information.
4. Languages, because big markets draw many tourists.
5. Experience with city and outdoor events.
6. A bad-weather plan agreed with the organiser.

MERA Robotics from Warsaw rents Unitree G1 and Unitree H2 robots together with its own operators and spare batteries, and checks every robot before an event. The company delivers city and municipal events in Poland and abroad, including an international trade fair in Cannes in September 2026. Conversations run on its own MERA OS in more than 30 languages, with a voice matched to each language. MERA's robot Edward Warchocki became known worldwide after a video from a Warsaw street that was covered by Reuters, CNN and BBC News, among others. Pricing depends on how long the robot is needed, the location and logistics. Enquiries: contact@merarobotics.com or the form at merarobotics.com.
