On September 23, 2026, Boston Dynamics officially opened the first phase of the Robotics Metaplant Application Center (RMAC), a dedicated factory-level training facility for the electric Atlas humanoid robot, located inside Hyundai Motor Group's Metaplant America (HMGMA) in Bryan County, Georgia, near Savannah. Hyundai plans to deploy 25,000 Atlas units across Hyundai and Kia global factories in the coming years.
Key takeaways
- RMAC is a real factory-floor training site, not a demo hall: Phase 1 is operational, and a new building roughly ten times larger is expected in 2027.
- Hyundai Motor Group plans to deploy 25,000 Atlas robots in Hyundai and Kia plants worldwide.
- Boston Dynamics also plans a US-based production facility with 30,000 Atlas units/year capacity—the largest mass-production plan announced by any humanoid robotics company so far.
- The electric Atlas is still described as a "humanoid robot platform under development," with no production start date given.
- Hyundai Motor Group's existing industrial robot fleet: ~50,000 units (traditional arms and cobots).
- Global automotive industry robot fleet: ~1,000,000 units.
- Global deployed humanoid robots (as of mid-2026): ~20,000 units, about 95% in China.
- 2026: Logistics, parts sequencing, pre-assembly preparation (active)
- 2027 onward: Component assembly
- 2030 onward: High-repetition, high-intensity tasks including heavy lifting
- The number of Atlas units at RMAC
- Which subtasks already run autonomously
- Cycle time, positioning accuracy, uptime, or other performance data
- Tesla Optimus: small-scale production before end of 2026; industry estimates of 50,000–100,000/year as a starting point
- Figure: 10,000/year (RoboFab facility)
- Agility Robotics: ~10,000/year scale (Digit, RoboFab 2027 plan)
- Boston Dynamics: 30,000/year (planned, no timetable given)
- Figure: Helix 2.5 zero-shot 30-room generalization (July 2026)
- Agility: Digit 5 launch with over $300M in orders (August 2026)
- Tesla: Optimus production acceleration and Yangtze Delta supplier audits (August 2026)
- Apptronik: Apollo 2 whole-body coordination demo (September 2026)
- XPeng: IRON targeting thousands of units/month by end of 2026
- Progress on RMAC Phase 2 ahead of the 2027 opening
- When Atlas achieves fully autonomous parts sequencing (no teleoperation)
- Financial details behind the 25,000-unit commitment
- How the Tesla Optimus vs. Atlas technology curves diverge
The numbers in context
The promised 25,000 Atlas units would approach half of Hyundai's existing robot fleet and more than double the world's installed humanoid base—closer to a purchase commitment than a pilot.

This is the first time Boston Dynamics has given Atlas an explicit application-expansion schedule.
What RMAC Phase 1 actually does
The announcement is deliberately restrained: trainers are teleoperating Atlas, which is performing logistics and parts-sequencing—arranging automotive components in assembly order. Not disclosed:
One confirmed fact matters a great deal: RMAC shares a building with Hyundai's real automotive production line, so Atlas trains with real parts from real stations—fundamental to training-data authenticity.
The 30,000/year US production plan
Boston Dynamics plans a US manufacturing facility with 30,000 units/year of Atlas capacity—about 2,500 per month, comparable to the monthly output rhythm of traditional industrial robot arms (e.g., ABB IRB series). Benchmark plans:
Strategically, Boston Dynamics is positioning itself as a next-generation industrial automation supplier, deeply bound to a top-ten global automaker—more stable than a pure R&D model, but with single-customer concentration risk.
Why RMAC sits inside the Metaplant
Unlike traditional training centers located away from customer factories, RMAC is embedded in the plant itself:
1. Continuous real-data feedback: Real parts, deformation, oil stains, mislabeled parts, and missing components—the long-tail cases simulation cannot capture—feed directly into the training pipeline, an extreme form of sim-to-real. 2. Near-zero fault recovery time: Engineering teams can reach Atlas within minutes when issues occur, versus weeks under conventional deployment models. 3. Human-robot coexistence: Trainers operate Atlas alongside Hyundai staff in the same physical space—the most direct cobot scenario and a serious test of humanoids on the factory floor. (Trainers are likely Boston Dynamics engineers, though not specified.)
What was left unsaid
| Not disclosed | Likely reason | |---|---| | Number of Atlas units at RMAC | Numbers adjust with training | | Share of tasks running autonomously | Autonomy rate still climbing; teleoperation-dominant | | Timeline for the 25,000-unit deployment | Staged factory ramp-up | | Site of the US production facility | Early planning stage | | Financial terms between Hyundai and Boston Dynamics | Commercial confidentiality |
The most telling omissions are unit counts and autonomy rates—the hard indicators of production progress and AI capability, respectively.
Industry context (2026 H2)
Unlike Tesla's supply-chain auditing, Boston Dynamics is already training robots inside a customer plant. RMAC signals that humanoids have moved from demos to in-factory training, that customer demand has been validated at the 25,000-unit scale, and that Boston Dynamics is betting on both US manufacturing reshoring and next-generation industrial automation.
What to watch over the next 12 months
