 Levels of autonomy (LASR) and AI integration (LIAI2) classification scales.

ScalePurposeRangeCore concept at the highest level
LASR (autonomy)Classifies the robot’s degree of independence from human control0 (no autonomy) to 5 (full autonomy)Full autonomy: The system performs the entire procedure based on predefined objectives without human intervention.
LIAI2 (integration)Classifies the sophistication and depth of integration of AI and advanced imaging within the workflow1 (guided assistance) to 5 (full autonomous navigation)Full autonomous navigation: The system fully integrates advanced imaging and AI to independently perform and navigate the intervention.

AI: artificial intelligence; LASR: Levels of Autonomy in Surgical Robotics; LIAI2: Levels of Integration of Advanced Imaging and AI.
