Motion scaling – which allows the robotic arms to mimic the exact movements of the surgeon’s hands, but on a much smaller scale – will enable surgeons to manipulate tissue that is too small for the naked eye to detect. With the development of smaller microsurgical tools and high-performance cameras and monitors, operating at the cellular level will be possible.
此外，机器人手术具有超过无辅助人类能力的潜力。按比例动作缩放——该技术让机器手在小得多的规模上精确模拟外科医生的动作——将能使外科医生操纵肉眼无法察觉的组织。围着更小规模微型外科手术工具和高性能相机和显示器的发展，细胞层面的手术将成为可能。
