Mashable watched the UC San Diego humanoids. They still need a surgeon, and a cooling break.

Mashable's October 5 visit shows the Unitree G1 setup from UC San Diego's July pig gallbladder trial. Shoulders overheat, and the bodies are not sterile enough for a human operating room.

Mashable's camera crew spent October 5 at UC San Diego's Center for the Future of Surgery and titled the visit like a debut: the first humanoid robot surgeon. The operations they walk through happened in July. We wrote that trial up when it landed in Nature. The new video is a look at the same machines, from the side of the table.

The July cases used Unitree G1 humanoids the lab calls Surgie. A surgeon sat at a console and drove the arms. One procedure paired a robot with a human assistant. The next put two robots side by side. Both were gallbladder removals on live pigs, not people. The university still calls that a first for this kind of robot. It is not a robot deciding where to cut.

Standing in the lab, the October report is blunter about the body. The G1's arms are shorter than a surgeon's, so the team keeps shifting the robot to reach the ports. The shoulder joints overheated on a long case, and the work stopped while they cooled. The same write-up says the robots could not be sterilized the way an operating room sterilizes steel tools. A research kit you can buy is not a body you wheel into a human case.

The July paper already had the other catches. The team paused to recalibrate, sometimes for more than three minutes. A person still placed the clips, because the robot had no clip tool of its own. On practice tasks, the humanoid landed between a surgeon's own hands and a purpose-built system like da Vinci. Michael Yip's group talks about a later helper that could fetch instruments. The October chapters ask whether the arms could run without a person. The footage still has someone on the controls.

Unitree G1 stays the catalog robot you can order, from $13,500, for labs and developers. This visit does not change that price, and it does not turn Surgie into a product you book.
