Researchers at the University of California, San Diego have achieved a significant milestone in robotic medicine after humanoid robots successfully performed gallbladder removal surgeries on live pigs, marking one of the most advanced demonstrations yet of humanoid robotic surgery.
The groundbreaking research, published in the journal Nature, represents an important proof of concept that could eventually pave the way for human clinical trials. While the technology remains in the preclinical stage, scientists believe the success could reshape the future of surgery by expanding access to specialized medical care around the world.
Historic Robotic Procedures
The UC San Diego research team completed two separate laparoscopic gallbladder removal procedures using humanoid robots nicknamed “Surgie.”
During the first operation, a humanoid robot worked alongside a human surgeon, who assisted throughout the procedure.
The second operation marked an even greater milestone, with two humanoid robots successfully completing the surgery together without direct human assistance during the operation itself.
Researchers described the achievement as an important step toward eventually testing the technology in human patients.
“As a proof of concept, it absolutely worked,” said Dr. Ryan Broderick, interim director of UC San Diego’s Center for the Future of Surgery.
A Different Kind of Surgical Robot
Unlike conventional robotic surgical systems currently used in hospitals, the new humanoid robots are designed with a human-like body featuring a head, torso, and two arms.
Their compact size allows them to move naturally around an operating room without requiring the large, stationary robotic platforms commonly found in modern hospitals.
“The space constraints didn’t exist like in traditional robotic surgery,” Broderick explained.
Researchers believe this design could significantly simplify surgical workflows while making advanced robotic procedures possible in smaller hospitals and mobile medical facilities.
Expanding Access to Surgery
One of the team’s primary goals is improving access to quality surgical care.
Researchers envision the humanoid robots eventually assisting patients in:
- Rural hospitals
- Military field hospitals
- Ships at sea
- Disaster relief operations
- Remote villages
- Developing nations
- Emergency response environments
Dr. Shanglei Liu believes the technology could dramatically improve healthcare availability in locations where specialized surgeons are difficult to recruit.
“You can imagine this device being deployed on a ship, in a village somewhere, in a smaller operating environment that’s not in major cities,” Liu explained.
Addressing Healthcare Worker Shortages
Hospitals across the United States continue facing staffing shortages affecting nurses, surgical assistants, and operating room personnel.
Researchers believe humanoid robots could eventually assist surgical teams by:
- Preparing operating rooms
- Handling surgical instruments
- Assisting during procedures
- Transporting equipment
- Supporting surgeons in repetitive tasks
Michael Yip, professor of Electrical and Computer Engineering at UC San Diego and one of the study’s senior authors, said the long-term goal is collaboration rather than replacement.
“Our goal is an operating theatre of the future, where humanoid robots and humans work side by side as an integrated team.”

Challenges Still Remain
Although the surgeries were successful, researchers acknowledge several technical hurdles remain before human clinical trials become routine.
Current limitations include:
- Communication latency
- Robot recalibration during procedures
- Increased operating time
- Additional safety validation
- Regulatory approval
Because the surgeries were remotely operated rather than fully autonomous, surgeons maintained control throughout the procedures.
Researchers stress that additional animal studies, safety testing, and regulatory review will be required before the technology can be evaluated in human patients.
The Future of Surgery
Medical robotics has advanced dramatically over the past two decades, with robotic-assisted systems already performing millions of procedures worldwide.
Humanoid robotic platforms represent the next stage of development by combining advanced dexterity with human-like mobility.
Rather than requiring specialized operating rooms built around large robotic systems, these compact robots could eventually work alongside surgeons in existing hospitals while expanding access to advanced surgical care in underserved communities.
If future human trials prove successful, today’s experimental technology may eventually become a familiar sight in operating rooms around the world.
Faith Perspective
Advances in medical technology have long helped physicians save lives and reduce suffering. Many people of faith view medicine as one way human creativity and knowledge can be used to care for others. At the same time, rapid developments in artificial intelligence and robotics raise important ethical questions about accountability, oversight, and preserving the central role of human judgment and compassion in patient care. As these technologies continue to evolve, thoughtful stewardship and ethical safeguards will remain just as important as scientific innovation.
Conclusion
The successful gallbladder surgeries performed by humanoid robots represent a remarkable step forward in robotic medicine.
Although the technology remains years away from widespread human use, researchers believe these early successes demonstrate that compact humanoid robots could eventually expand access to surgical care, support healthcare workers, and transform operating rooms around the globe.
Whether assisting surgeons in major hospitals or delivering life-saving procedures in remote communities, humanoid surgical robots may become one of the defining medical innovations of the coming decades.
Frequently Asked Questions
What procedure did the humanoid robots perform?
The robots successfully completed laparoscopic gallbladder removal surgeries on live pigs during preclinical testing.
Were the surgeries performed on humans?
No. The procedures were conducted on pigs as part of preclinical research before any human trials.
Who developed the robots?
Researchers and surgeons at the University of California, San Diego conducted the study.
Are the robots fully autonomous?
No. The surgeries were teleoperated, meaning human surgeons controlled the robots remotely during the procedures.
When could humans receive surgery from these robots?
Researchers say additional testing, regulatory approval, and human clinical trials are still required before widespread medical use.
