Elon Musk has shared an update about his brain chip implant startup, Neuralink. The world’s richest man reposted an X post from Neuralink, which said the company is developing a surgical robot to implant its brain-computer interface (BCI) and potentially treat brain-related conditions. In the X post, Neuralink said, “We’re building a surgical robot capable of reaching any brain region. The goal: a generalised neural interface to help solve any condition that originates in the brain.” Musk reposted the announcement and wrote, “Neuralink progress.”The robot is being developed alongside Neuralink’s coin-sized implant, which is placed beneath the skull to interpret neural signals and translate them into digital commands.
How Neuralink’s surgical robot can automate brain implant procedures
Neuralink’s official website says the surgical robot is designed to automate key parts of the implantation process to improve precision and consistency. The system uses an ultrafine needle, thinner than a human hair, to insert flexible electrode threads into the brain.Danish Hussain, head of surgery and mechanical engineering at Neuralink, said, “Here at Neuralink, the robot is critical to our surgical process. After the surgeon has created the opening in the skull and lined up the brain to the robot, the robot’s role is to grab threads off the implant and insert them into the brain.”This robot can move along multiple axes and uses an imaging system and sensors to implant electrodes without damaging blood vessels. It offers a less invasive alternative than previous techniques.According to a report by Engineering and Technology, Neuralink began human trials of its PRIME study last year, with a participant undergoing surgery at the University of Miami Health Centre. While initial procedures were carried out by surgeons, the company is working toward greater automation using the robot.John Harris, head of robot mechanical engineering at Neuralink, said, “The reason we need a surgical robot is that these thin, flexible electrodes are almost impossible for a surgeon to place one by one. Imagine placing a single strand of hair into Jello, and then having to do that hundreds of times.”The implant’s electrodes detect neural activity and transmit signals wirelessly to external devices, enabling users to control systems such as a computer cursor.The company said the robot has undergone multiple design iterations, with updates to its actuators, optics, and needle system. Engineers aim to improve speed and accuracy to support wider use in the future.Sebastian Messier, a mechanical engineer at Neuralink, said, “We want to go faster, we want the threads to go deeper, and help thousands more people. I think we’re going to look back and our grandchildren are going to think it was crazy that somebody could get in a motorcycle accident and never walk again. That’s what we’re working towards here. And it’s all going to be because this robot was able to insert threads that no human could imagine doing on their own.”Neuralink said the robot is not yet in its final form, but it remains central to its plan to expand the use of brain-computer interfaces.
