Humanoid robots, operated remotely by surgeons, removed gallbladders from live pigs in a first-of-its-kind preclinical trial.
The experiment, published in the journal Nature, involved teleoperated humanoid robots performing minimally invasive procedures on living animals. Surgeons controlled the robots' movements throughout — these were not autonomous machines making independent decisions. The research team behind the trial includes Shanglei Liu, an assistant professor of surgery at the UC San Diego School of Medicine.
The significance here is less about the surgery itself and more about the hardware. Specialized surgical robots already exist, but they are expensive and require significant floor space, limiting their use to well-resourced hospitals. Humanoid robots, by contrast, could slot into smaller operating rooms at a fraction of the cost — making remote robotic surgery plausible for rural clinics, military field settings, or, per Liu, even space.
The gap between "worked on pigs in a trial" and "cleared for human patients" is substantial, and Nature publications have a way of generating headlines that outrun clinical timelines. Still, if the cost and size advantages hold up under scrutiny, this is a more pragmatic case for humanoid robots in medicine than the autonomous-surgeon narrative that usually dominates the pitch deck.
