AI Surgical Robot Achieves Flawless Gallbladder Removal on Pig Cadavers
UNITED STATES, JUL 10 – The Surgical Robot Transformer-Hierarchy completed 17 complex gallbladder removal tasks with 100% accuracy on pig cadavers, marking a major step toward autonomous surgeries, researchers said.
- On July 9, 2025, Johns Hopkins researchers announced that a robot autonomously performed a gallbladder removal on a pig cadaver with 100% accuracy in a laboratory setting.
- This milestone followed prior work in 2022 when Axel Krieger's team created AI systems that taught robots foundational surgical skills by watching videos and performing small animal surgeries.
- The robot completed the 17-step procedure eight times, self-correcting multiple times and responding to voice commands, demonstrating adaptability even during unexpected situations.
- Ji Woong Kim stated that their research demonstrates AI technology has reached a level of dependability suitable for autonomous surgery, while Krieger highlighted that the system responds dynamically to anatomical variations in real-time, similar to how a human surgeon operates, marking a significant advancement toward practical clinical use of autonomous surgical robots.
- Researchers stressed the need for further testing, expanded surgical capabilities, and regulatory approval before clinical use, as challenges remain to safely translate this technology to human patients.

Humanoid robot Ai-Da that sold first robot art at auction for over $1 million now says it's not aiming to ‘replace human artists’
The ultra-realistic robot, one of the most advanced in the world, is designed to resemble a human woman with a life-like face and brown hair cut in a bob.
Trained with both machine learning and verbal instructions, SRT-H is not as fast as a human, but its work rivals that of trained surgeons.
The fact that AI models are reliable, autonomous surgeons is now confirmed by an experiment by researchers from Johns Hopkins University in the USA. Using artificial intelligence, the robot has removed a gallbladder from pigs without help.
