Walden Robotics is a Cambridge, Massachusetts full-stack Physical AI company building general-purpose robots that continuously learn on the job. Spun out of Toyota Research Institute work on Large Behavior Models, Walden deploys robots into manufacturing and logistics production environments from day one.
Walden Robotics is a full-stack Physical AI company building and deploying general-purpose robots that continuously learn and improve while performing real work. Founded in 2026 by robotics and AI pioneers from Toyota Research Institute, MIT, Stanford, and Amazon, Walden commercializes Large Behavior Models (LBMs) and related research including Diffusion Policy. Co-founder and CEO Dr. Russ Tedrake is a professor at MIT and former SVP of Large Behavior Models at TRI. Walden launched out of TRI in January 2026 and, since February 2026, has robots performing useful production work at a Toyota plant in North America. On July 15, 2026 the company emerged from stealth with US$300M in funding at a US$1.1B valuation, co-led by Toyota (Toyota Motor Corp, Toyota Invention Partners, Toyota Ventures) and Deviation Capital, with participation from NVIDIA, Boeing, AE Ventures, Samsung Ventures, Prologis Ventures, CoreWeave Ventures, Calibrate Ventures, Menlo Ventures, and others. Target applications include machine tending, tool setting, parts kitting, and assembly across automotive, aerospace, semiconductors, electronics, logistics, and life sciences.

July Was Loud in Robotics — Here's What Actually Mattered
Dhruv AtkinsTrack Walden Robotics's valuation over time.
In January 2026 Walden launched out of Toyota Research Institute, combining hardware, software, frontier Physical AI, and an application layer for manufacturing and logistics deployments.
Walden reported that from February 2026 its general-purpose robots have been doing useful production work—loading/unloading parts, cleaning machinery, kitting—on multi-hour shifts alongside human teams at a North American Toyota plant, moving from pilot to real work in under two months.
January 2026 - Walden launches out of Toyota Research Institute to commercialize Large Behavior Models and full-stack general-purpose robots for real production work.
February 2026 - Walden robots begin useful production work at a North American Toyota plant, moving from pilot to real shifts in under two months (loading/unloading parts, cleaning machinery, kitting for assembly).
July 15, 2026 - Walden emerges from stealth with US$300M seed-stage funding at a US$1.1B valuation, co-led by Toyota entities and Deviation Capital with a broad strategic investor syndicate including NVIDIA, Boeing, AE Ventures, and Samsung Ventures.
The company positions its robots as useful from day one in manufacturing and logistics, continuously improving through real-world practice while keeping skilled people at the center of production work.
