Boston Dynamics' 25,000-Robot Plan Runs Into a Union in Korea

Boston Dynamics opened the first phase of a training facility for its Atlas humanoid robot at Hyundai Motor Group Metaplant America on Sept. 21, built to prepare the 25,000 Atlas units Hyundai has committed to its own factories. Zack Jackowski, Boston Dynamics' chief product and technology officer, called the Savannah, Georgia, site a "Robot Behavior Factory," built to teach Atlas automotive tasks before it works unsupervised on a production line.

The Robot Report was first to report the opening. The facility, called the Robotics Metaplant Application Center, combines real automotive parts, fixtures and workcells with Atlas units and human operators. Boston Dynamics trains the robot three ways: teleoperation, reinforcement learning run in simulation, and recordings captured with handheld Universal Manipulation Interface devices that let an operator demonstrate a motion without the robot itself. The company's own blog post introducing the arrangement, "Enterprise Robotics, Redefined," names Hyundai as Atlas's first production customer and says a fleet was scheduled to ship to the center in 2026.

What "first phase operational" does not say

Boston Dynamics said the center's first phase is running and that a second building, about 10 times the size, opens in 2027. It did not say how many Atlas units are inside the current building, how many hours a day they run without a teleoperator nearby, or what share of tasks they finish without a human stepping in. "First phase operational" and "generally deployed" are different claims, and Hyundai's 25,000-unit figure is a target for its global Hyundai and Kia plants over the next few years, not a count of robots working today.

That gap matters more than it would for most factory equipment, because Atlas is not close to running a full shift on its own. A September 2026 review of humanoid deployments in auto plants found Atlas's battery lasts two to four hours depending on the task, that a swap takes three minutes, and that a full charge takes an hour and a half, meaning a shift of eight to 12 hours needs several swaps. The same review found the robot still underperforms conventional industrial arms on speed, precision and repeatability, and struggles to grip parts it has not seen before in a consistent shape, size or weight. For comparison, Figure AI's rival humanoid, Figure 02, had logged about 1,250 operating hours and 1.2 million steps over 10 months at a BMW plant supporting production of more than 30,000 X3 vehicles, a pace that gives some sense of how much runtime one unit accumulates even in an established deployment.

Atlas spec	Value
Height	1.9 meters
Reach	2.3 meters
Battery life	Up to 4 hours
Battery swap time	Under 3 minutes
Repeated lift capacity	30 kilograms
Operating temperature	-20°C to 40°C

The denominator Hyundai has not disclosed

Boston Dynamics and Hyundai have been specific about the ceiling: 25,000 Atlas units at Hyundai Motor and Kia plants, and a U.S. factory Hyundai wants building up to 30,000 robots a year by 2028. Neither company has said how the 25,000 figure splits between Georgia, Hyundai's other U.S. sites and its plants in South Korea, where Hyundai Motor actually builds most of its cars.

That omission is not incidental. The Korean Metal Workers' Union's Hyundai Motor branch said in January 2026 that "not a single robot can enter the workplace without labor-management agreement," and named the union's summer 2026 contract talks as the point where the dispute was expected to come to a head. Robert Playter, Boston Dynamics' chief executive, has described the robots' role as taking on "the really repetitive, really back-breaking labor," which is precisely the kind of job a metalworkers' union counts as headcount. Georgia's Metaplant is not unionized, which is one reason Boston Dynamics can open a training center and describe a fleet shipment there without clearing that hurdle first. Hyundai's home country is a different arithmetic, and the 25,000-unit figure means little without knowing how many of those units are meant for plants where the union has already said no.

What would change the read

None of this means the Georgia buildout is not real. The first phase is running, and Boston Dynamics has committed to a second building, about 10 times the size, opening in 2027. What would change this read is Boston Dynamics or Hyundai publishing an actual operating-hours figure out of the Metaplant Application Center, the way Figure AI's BMW deployment already has, or the Korean union reaching a labor agreement that lets Atlas onto a production line in the country where Hyundai builds most of its cars. Until one of those happens, the verified count of working Atlas units is the first phase of one Boston Dynamics facility in Georgia, not 25,000, and the XPeng humanoid program racing to catch up faces the same gap between a funding number and a shift count. Boston Dynamics is not alone in leaving that number out: the cheapest open-source robot arms on the market still ship with no published duty-cycle figure either, which is the same omission at a tenth the price.
