Nature Reports Demonstration of Humanoid Robot Surgery in a Live Pig

A demonstration study applying a humanoid robot to laparoscopic surgery was published in Nature on July 8, 2026. The research team developed a humanoid teleoperation system using general-purpose surgical instruments and conducted a benchtop evaluation, dry-lab trials with users of varying levels of surgical experience, and an in vivo trial in a live pig. Through these evaluations, the team quantified technical feasibility, task performance and clinical readiness compared with existing surgical platforms.

The study is significant because it systematically evaluated, for the first time, how far humanoid robots can be applied to a highly specialized medical procedure such as surgery. Depending on the results, it could affect the competitive landscape of the surgical robot market and how robots are used in medical settings.

This study is groundbreaking in showing, through systematic evaluation, how close humanoid robots are to practical use in surgery, particularly minimally invasive surgery. Conventional surgical robots have largely been platforms designed specifically for surgery, represented by Intuitive Surgical’s da Vinci system. In contrast, this study takes an approach that combines a general-purpose humanoid with general-purpose surgical instruments to perform laparoscopic surgery through teleoperation. This sets it apart from existing purpose-built robots. The study was structured in three stages: benchtop evaluation, dry-lab trials and in vivo trials in a live pig. It examined the process step by step, from technical feasibility to clinical readiness. In particular, the dry-lab trials involving users with varying levels of surgical experience provide evidence of how acceptable the humanoid’s operability may be not only to experienced practitioners but also to beginners. This is important data for considering adoption in clinical settings. In terms of implications for the industry, the study indicates that humanoid robots are expanding beyond nonmedical fields such as logistics and caregiving into medicine, where high precision and safety are required. If humanoids become practical for surgery, the advantage held by purpose-built machines in the surgical robot market could be shaken. However, this study is only an evaluation of feasibility, and many challenges remain before clinical application. The paper’s abstract also refers to “critical technical challenges that must be addressed before clinical translation,” including the humanoid’s control precision, adjustment of force and safety assurance. Unresolved questions include which humanoid model was used in the study and details of the quantitative performance comparison with existing surgical robots, which are not clear from the abstract. Further information is also awaited on the success rate of the live-pig trials and whether clinical trials are planned.

The research team developed a teleoperation framework for laparoscopic surgery using a humanoid robot. The evaluation was conducted in three stages: benchtop characterization, dry-lab trials with users of varying levels of surgical experience, and in vivo trials in a live pig. Numerical source data and analysis code from the dry-lab trials are available on Zenodo (DOI: 10.5281/zenodo.20434260). Code supporting the study is also available on Zenodo (DOI: 10.5281/zenodo.18023650).
