Suzhou, China — Lumos Robotics, a developer of embodied-intelligence systems for industrial applications, has launched MOS2, its next-generation heavy-duty mobile manipulator — and the machine is not waiting for a showcase. It is already deployed on Mitsubishi Electric's core PLC production lines, performing flexible quality inspection, box pushing, screwdriving and material handling.
Built like a worker, not a performer
Positioned as an "AI Worker" rather than a demonstration platform, MOS2 pairs a 50-kilogram-class dual-arm payload with a compact footprint: roughly 1.65 meters tall and just 0.5 square meters of floor space, small enough to maneuver through narrow factory aisles. Rapid end-effector changes let it switch between tools and workflows on the fly, extending its reach from quality control into intralogistics and assembly. Visual and force sensing combine into multimodal perception, so the robot can recognize task conditions and adapt to changes on dynamic lines without extensive pre-calibration.
"Products cannot be perfected in the laboratory alone. They have to be tested, validated and iterated in real-world environments," said Yu Chao, founder and CEO of Lumos Robotics. "Dancing, running and doing backflips may demonstrate a robot's physical capabilities, but they do not prove its industrial value. What industrial customers ultimately care about is task success rate, production cycle time, deployment time and return on investment."
A track record before the launch
The launch rests on a year of validation on the factory floor. The first-generation MOS robots have completed more than 1,000 hours of continuous, failure-free operation at Mitsubishi Electric's Changshu factory, closing the loop between manufacturing-floor data and embodied-operation models.
On PLC visual inspection lines, the robots autonomously identify products of different sizes and use coordinated dual-arm movements to run six-sided, unobstructed defect inspections — before moving on to material handling, screwdriving and box handling, tasks that stretch the system well beyond quality control.
From customer to lead investor
The relationship behind MOS2 is as notable as the hardware. In 2025, Mitsubishi Electric and Lumos Robotics signed a strategic cooperation agreement that opened four industrial scenarios to the startup: quality inspection, assembly, sorting and material handling. Joint laboratories in Suzhou and Shanghai followed, where their jointly developed flexible inspection solution progressed from laboratory validation to live production lines.
In May 2026, Mitsubishi Electric Smart Manufacturing Technology (China) Group Co., Ltd. led Lumos Robotics' Series A1 and A2 financing rounds, lifting the company's cumulative funding above 1 billion yuan (roughly $140 million) since inception.
"Mitsubishi Electric first became our customer and then our investor," Yu Chao said. "This progression shows that customers can first recognize the practical value of our products and then come to recognize the company's long-term value."
What comes next
Lumos Robotics plans to use the Mitsubishi Electric deployment as a benchmark case for pushing MOS2 into a broader range of industrial environments, including electronics, automotive and semiconductor manufacturing. The company operates bases in Suzhou and Nanjing, positioned close to the Yangtze River Delta's manufacturing supply chains — and its stated ambition is to accelerate embodied AI's move from laboratory demonstrations to continuous, scalable deployment on real factory floors.
For an industry still arguing over how to score humanoid showcases, Lumos is staking its case on a different scoreboard: task success rate, cycle time and ROI. The MOS2 launch — a robot already working, not one preparing to — is the clearest signal yet of where the startup believes industrial embodied intelligence will be won.
