Abstract generation in progress
Recently, a paper titled “Live Feasibility Study of Humanoid Robots for Surgical Procedures,” published online by Nature, has drawn attention. The research team brought Unitree Technology’s G1 humanoid robot into an operating room, where human surgeons performed standard laparoscopic cholecystectomy procedures on two live pigs using a remote teleoperation system. This study is also known as the world’s first live surgery performed using a humanoid robot. The paper’s first author, Lucas Zekai Liang, a PhD in the Department of Electrical and Computer Engineering at the University of California, San Diego, exclusively replied to a First Financial reporter via email. He said the project was jointly completed by an interdisciplinary team made up of engineers and surgeons, and that Unitree G1 was chosen mainly because, at the time, it was one of the more readily available commercial options in the market. The research focus of the project was the humanoid robot’s human-like appearance, rather than a specific platform. “For humanoid robots to be truly applied in clinical practice for human patients, it still will take quite a long time,” Liang said. He added that before deploying humanoid robots in clinical settings, further improvements are needed in areas such as precision, sterilization, safety, regulatory approvals, and large-scale validation.
