Design Principle

Precision in complex procedures can be significantly enhanced through integrated sensor feedback (vision, force) and automated control systems.

How to Apply

When designing automated or semi-automated systems for precise placement or assembly, consider integrating cameras for real-time visual tracking and sensors for force or tactile feedback to guide the process.

Limitations

Experiments were conducted on 3D-printed models, and further validation on human patients is required. The study focused on positioning accuracy, with less emphasis on long-term functional outcomes.
