Cortical Labs, a biocomputing company based in Melbourne, has wired a group of human neurons grown on a chip to a four-legged robot dog, and the neurons steer it toward a target marked on a simple map. The demo has been circulating since the second half of October 2026, with ScienceAlert covering it on October 31 and New Atlas writing about it on the 19th. Cortical Labs grows human neurons, derived from stem cells, directly on a silicon chip full of electrodes that send electrical signals to the cells and read their responses in both directions. The product is called CL1, which the company presents as the first biological computer programmable with code and, according to PC Games Hardware, costs about $35,000. Cortical Cloud lets users write Python code from a browser with Jupyter notebooks and run it on a network of CL1 units. The quadruped heads toward a goal on a basic map, with movement arising from the activity of a small group of nerve cells; the company speaks of electrical feedback loops guiding the robot, while New Atlas reports the frequency at which the neurons fire steered the movements. Cofounder and chief executive Brett Kagan calls it a simple demonstration, useful for making tangible the idea that progress in biological systems can leave the lab, and says over the long run such an approach could serve robots and autonomous systems that must make decisions in unpredictable environments.
