Hyundai's Ulsan strike shows the humanoid robot fight has moved to the factory floor

The strike began on 13 July. Day and night shifts at Hyundai's automotive production complex in Ulsan, South Korea, ended two hours early from 13 to 15 July. The union planned four-hour strikes from 20 to 22 July, The Korea Times reported. Ulsan is the world's largest automotive plant.

The trigger is Atlas, the two-legged humanoid built by Boston Dynamics, the US robotics company that is about to become a wholly owned Hyundai subsidiary. Hyundai Motor Group showed the latest version at the start of this year.

Its scale is the point. Hyundai aims to deploy more than 25,000 Atlas robots across Hyundai and Kia manufacturing plants, The Korea Herald reported. The company says it will start with US factories in 2028 and has not disclosed a timeline for anywhere else.

The economics that worry the union

Each Atlas costs an estimated $130,000 but may pay for itself within about two years of operations, according to Samsung Securities analyst Esther Yim, speaking to Bloomberg. James Hong of Macquarie Securities Korea Ltd. suggested that if the robot cost eventually falls to $100,000, its operational cost could drop below the US federal minimum wage of $7.25 and significantly undercut a typical auto worker's salary.

The Hyundai Motor union represents more than 39,000 South Korean workers. It wants production workers' hourly pay shifted to a fixed salary to cushion any automation-driven cut in work hours, and it wants the retirement age raised from 60 to 65, The Wall Street Journal reported. Bigger bonuses are also on the table.

Hyundai is not alone in this. Tesla is developing Optimus for its own electric vehicle factories. BMW has run pilot tests with humanoid robots from Figure AI at its plant in Spartanburg, South Carolina. Chinese carmakers including BYD are trying humanoids too, and some are building their own.

"The real value going forward is for our robots to be contextually aware of their environment and able to use their hands to manipulate any object," Robert Playter, CEO of Boston Dynamics, told WIRED. "And we think manufacturing environments, like in Hyundai factories, are a perfect place to deploy that today."

That January 2026 WIRED report described Google DeepMind putting its Gemini Robotics model on Atlas and Spot, with tests planned at Hyundai factories. Playter's counterpart at Google DeepMind, Carolina Parada, framed automotive as a starting point rather than the end goal.

Georgia first, and a weaker union

Hyundai's first Atlas deployment is set for Metaplant America, its EV factory outside Savannah, Georgia, starting in 2028. The company may meet less organised resistance there because the Georgia workers are not unionised. The United Auto Workers, which represents about 400,000 autoworkers across the US, Canada and Puerto Rico, has been trying to organise the site.

Metaplant America is already described as the most heavily automated automotive factory in the United States. IEEE Spectrum reported it has more than 850 robots unloading parts, stamping steel, assembling frames and installing doors, plus 300 automated guided vehicles moving parts between stations. Boston Dynamics' four-legged Spot is on site doing what the company calls exterior quality inspection in the weld shop. An Atlanta Journal-Constitution reporter visiting in July 2026 described the robotic dogs probing sensor-embedded noses to sniff out defects.

Atlas would start with sorting and organising parts. Jerald Roach, a general assembly executive at Metaplant, told the AJC the humanoids would not threaten the human workforce. He pointed to the sense of feel and touch in human hands, which he said is needed for soft parts such as hoses, wires, carpets and trim panels.

Hyundai has committed to 8,100 full-time human workers at Metaplant America by 2031 under its economic development deal with Georgia. State and local leaders provided an incentive package worth an estimated $2.1 billion. The AJC found the facility already employed more than 3,800 workers by the end of 2025.

The older automation story

None of this arrives on empty ground. More than 1 million robots were already in automotive factories worldwide by 2021, accounting for one third of robots across all industries, according to the International Federation of Robotics. The United States had deployed 38,000 industrial robots as of 2025, with the automotive industry alone installing 13,500 units.

What is different now is the pitch. Traditional industrial robots do one task. Humanoid makers argue their machines, running the latest AI models, could eventually do many tasks and fit into workplaces built for people. That requires solving training and hardware problems first, and the evidence from public demonstrations is mixed.

At the World Humanoid Robot Games in Beijing from 22 to 26 August 2026, robots beat human records in the 100-metre sprint and standing high jump, according to Ars Technica. Some also crashed into barriers, broke at the waist in showers of sparks, or caught fire because they could not stop running. Many competitors were still teleoperated, which the event penalised but allowed.

The organising question in Ulsan is simpler than any of that. Hyundai has 25,000 robots planned and a union with 39,000 members. Fifteen rounds of talks did not settle it.
