Neuralink Readies Robots to Place Its Brain Implants at Scale

Elon Musk stated that starting in 2026, Neuralink will commence mass production of brain implants, with a complete move to automated surgery for each implantation. People who have previously received the implant can already use it to control computers and robotic arms using only their thoughts.

Testing Phase and Financial Growth

Early testers—people who were paralyzed and had little mobility—were able to play video games, navigate the internet, post online, and move cursors across screens. Neuralink began human testing in 2024 after convincing regulators to approve the project despite safety concerns. By the end of last year, there were about twelve persons worldwide who had the devices fitted, with a more recent estimate putting the figure around twenty. Having some extra cash undoubtedly helped things along; in June, Neuralink received a 650 million dollar investment round, raising its valuation to roughly $9 billion. That money is going into device production and the work required to clean up the operating area.

High Precision and New Technologies

A video from the company demonstrates how it all works, with the machines taking over the difficult part of the process. The engineers created a specialized surgical method to allow the implant’s thin, flexible threads to nestle directly in the brain tissue. The threads are finer than a strand of hair and must pass through living tissue hundreds of times without causing damage. The prior manual process simply wasn’t precise enough.

Once a surgeon has made the initial cut in the skull, the robot takes over. It has eight cameras, an optical coherence tomography scanner, and can observe what’s happening under the brain’s surface in real time. It picks up each thread, places it in the proper location, and releases it cleanly. The arm that supports the implant is much smaller than it used to be, thanks to numerous design changes. This makes the system easy to use and much faster.

Process Optimization

It hasn’t always been smooth sailing, but they’ve lately reached a turning point. In previous iterations, the surgeon had to remove the dura—a protective barrier around the brain and spinal cord. Now, the robot simply pokes a hole in it and inserts the device without fussing around. This saves a step, speeds up the operation, and makes the entire procedure easier to repeat. They’ve already gone through several different variations; each has been adjusted to improve the actuators, optics, needle design, and sensor response. The present model has five axes so that it may adapt to any craniectomy spot that a patient requires.
