European startup Nucleus exited stealth on August 5, 2026, announcing that it had deployed humanoid robots into a German factory in under 90 days. The company sells no robots — it bills hourly for physical work completed, and the machines operate from day one under the control of remote operators.
Key takeaways
- Nucleus exited stealth on August 5, 2026 and deployed humanoids in a German factory.
- The deployment took under 90 days, which the company sums up as "Day 91."
- The business model is robotics-as-a-service — hourly billing for work done, with no hardware sales.
- The robots are Unitree G1 units with Nucleus-branded protective suits and custom grippers.
- The team is made up of veterans from CERN, ESA, 1X, NEURA Robotics, Agile Robots and Foundation.
Who Nucleus is
Nucleus is a European company that spent its first months in stealth. Its co-founder is Melvin Schwarz, and the company describes its team as veterans from institutions and firms including CERN, ESA, 1X, NEURA Robotics, Agile Robots and Foundation. That mix — big-science physics, the space sector and hands-on humanoid robotics — is meant to explain the pace at which the startup went from concept to a working deployment.
How the deployment works
Nucleus splits deployment into three stages. First it performs a 3D scan of the factory. Then it recreates the site in simulation to find bottlenecks in the processes. Finally, for about three weeks the robots work under human supervision, controlled remotely, while the system simultaneously gathers training data. The company says the machines do useful work from day one, rather than only after reaching full autonomy.
Nucleus's three deployment stages — from factory scan to supervised work and data capture.
Most of the industry is waiting for full autonomy before a real-world deployment. We move faster. Our humanoids perform useful work from day one.

Hardware: Unitree G1
Instead of designing its own robot, Nucleus uses humanoids from Unitree — specifically the G1 model. It is a relatively cheap humanoid: per the maker it stands 1.32 m, weighs about 35 kg, has 23 degrees of freedom and starts at $13.5K. Off-the-shelf hardware proved insufficient for logistics tasks, so the company added its own protective suits and custom end effectors — including ones for pulling boxes off shelves, where fingertip precision is required.

| Degrees of freedom | 23 |
| Price | from $13.5K |
Business model and data
Nucleus does not sell robots. It bills hourly for physical work completed, in a model it calls robotics-as-a-service?Robotics-as-a-service: A model where the customer pays for the work robots complete (e.g. hourly) instead of buying and maintaining the hardware.. Along the way it is building a proprietary dataset of industrial edge cases and treats it as a competitive advantage. The company compares the strategy to how Tesla and Waymo gathered driving data to train autonomous systems: the more real hours of work, the better the control models.
Why it matters
Nucleus reverses the usual order in humanoid robotics — instead of waiting for full autonomy, it leans on teleoperation and supervision as a way into factories right now. If hourly billing catches on, it lowers the barrier for plants that do not want to buy and maintain expensive hardware. The risk is baked into the model, though — remotely operated work is not autonomy, and the cost of human supervision may cap scaling. The value hinges on how fast the collected data translates into real relief for operators.
What’s next
- Nucleus says that by 2027 it wants to run one of the largest deployed humanoid fleets in the world.
- After the three-week supervised period, the company intends to increase autonomy using the data gathered at the German factory.
