Walden Robotics, a startup spun out from Toyota Research Institute and led by MIT professor Russ Tedrake, has raised $300 million（約480億円） at a $1.1 billion（約1800億円） valuation to build general-purpose robots that learn and improve while performing real work in manufacturing.
The company's robots have already been deployed at a Toyota plant in North America since February, handling production and logistics tasks, and are designed to help industries facing labor shortages while keeping people at the center of operations.
What happened
Walden Robotics emerged from stealth today with $300 million（約480億円） in funding and a $1.1 billion（約1800億円） valuation. The company, spun out from Toyota Research Institute in January and led by MIT professor Russ Tedrake, is building general-purpose robots that continuously learn while performing real work. Since February, the robots have been deployed at a Toyota plant in North America, handling production manufacturing and logistics tasks.
Why it matters
Walden's approach combines large behavior models with real-world deployment, aiming to address labor shortages and demographic shifts across industries including automotive, aerospace, semiconductors, electronics, and life sciences. The company builds its own full stack—hardware, software, and AI—rather than relying on off-the-shelf technology, positioning it to deliver immediate customer value while improving through operational learning.
What to watch
Toyota Motor Corp., Toyota Invention Partners, and Toyota Ventures led the round alongside NVIDIA, Boeing, and others. The robots feature a humanoid torso with two arms and a wheeled base, designed to make factory safety certification easier. Tedrake said the company will share more details on its training methodology soon.

Walden Robotics represents a convergence of academic robotics research and manufacturing operations, with Russ Tedrake bringing a decade of research from MIT and Toyota Research Institute into a commercially-focused startup. The company's emphasis on deployment in real production environments rather than laboratory settings marks a shift in how physical AI companies are approaching the market. By building the full stack in-house and working closely with Toyota—which spun out the company in January—Walden is positioning itself to avoid the gap between research capability and practical manufacturability that has constrained earlier generations of robotics startups.
The rapid deployment timeline is notable: robots were moved from initial pilot to production manufacturing tasks at a Toyota plant in under two months, suggesting that Walden's technology stack has already achieved sufficient maturity to deliver measurable value. Toyota's continued investment and strategic partnership, evident in the company's participation as co-lead of the funding round, signals confidence that Walden's approach aligns with real manufacturing needs. The robot's design—a humanoid torso with two arms and a wheeled base—was chosen partly for practical factory safety certification, reflecting Tedrake's stated commitment to pragmatism and respect for how manufacturing actually works today.
