Walden Robotics spins out of Toyota Research Institute

Traditional industrial robots work behind a cage, repeat a single task and were never designed for today's market complexities, which is why manufacturers now want general-purpose machines that can switch tasks and improve as processes evolve. Walden Robotics, which spun out of Toyota Research Institute in January 2026, is one bet on that shift. It launched with $300 million in July, and its robots have worked full production shifts alongside people since May, handling machine tending, parts kitting, and subassembly — work that had either failed to be automated or had never been attempted.

The technical path runs through compute long before the factory floor. CoreWeave, which has been betting on physical AI, brings mechanical engineers and robotics experts into customer engagements alongside its infrastructure, and its VP of field engineering John Mancuso notes that a tremendous amount of simulation happens in the virtual world before a model does anything physical. But simulation alone cannot make a robot perfect, so Walden pairs autonomous machines with remote human assistants — a setup Gaidon compares to the automated looms of 120 years ago, when one person oversaw 40 machines. Gaidon also points to the roughly half a million open machinist positions in the U.S., arguing that part of that job does not require craft or human creativity.

The outcome hinges on whether continuous learning on the job and human assistance really deliver the adaptability Walden promises, and whether factory operators come to trust robots that change their behavior after deployment. For manufacturers weighing general-purpose robots against cage-bound fixed automation, that trust question — not raw robot capability — looks like the deciding factor, and it is likely to be settled on live production lines rather than in simulation.
