Surgeons at the University of California San Diego complete preclinical procedures using humanoid robots. According to reports, the robotic system performs operations in two procedures involving pig models, removing gallbladders. The work is described as a first step toward potential human trials, with the surgeries used to demonstrate the robots’ ability to carry out delicate surgical tasks in a live setting. While the reports focus on the milestone of using humanoid robots in an operating room environment, they also frame the trials as animal-based tests rather than procedures on people. The two pig surgeries are presented as proof of concept for the robotic approach and a key step in the broader development pathway required before any human clinical use. Both sources report the same location, institution, and type of operation—gallbladder removal in pigs—highlighting that this stage remains limited to veterinary or laboratory research and does not yet represent clinical treatment for patients.
