A humanoid robot performed live surgery for the first time, steered the entire way by a human operator working remotely.
Researchers at UC San Diego's Center for the Future of Surgery tested a teleoperated humanoid robot during a live animal surgery. The team took a general-purpose humanoid body, built for walking and manipulating objects, and adapted it for an operating room, a harder problem than designing a surgical arm for one task from scratch. During testing, the robot ran into performance drops and overheating that operators had to manage mid-procedure. Live animal surgery was necessary rather than a simulation, since only real tissue and real stakes test whether a teleoperation setup actually holds up.
Robotic surgery already exists, but today's systems, like the Da Vinci, are fixed, single-purpose arms bolted into one operating room. A humanoid body raises a different possibility: one machine that walks between rooms, gets repositioned, or even travels to understaffed facilities instead of sitting idle between procedures. That promise only matters if teleoperation performs reliably under pressure, and the thermal issues here suggest it is not fully there yet.
The team is already floating the idea of AI autonomy down the road. For now, every incision still needs a human hand guiding it from somewhere else.
