One-Degree-of-Freedom System

761
In mechanical engineering, one-degree-of-freedom systems form the basis of a wide range of electrical and mechanical components. Using these models, engineers can predict the behavior of various parts in a larger system, which gives them insight into how different forces interact with each other.
A one-degree-of-freedom system is defined by an independent variable that determines its state and behavior. One example of a one-degree-of-freedom system is a simple harmonic oscillator, such as a...

Area of Science:

  • Robotics in Medicine
  • Surgical Navigation Systems
  • Medical Imaging and Image Processing

Background:

  • System calibration is critical for surgical robot accuracy.
  • Conventional methods struggle with irregularly shaped tools in orthognathic robot systems (ORSs), requiring manual intervention and reducing precision.
  • Automated calibration is needed to enhance efficiency and accuracy.

Purpose of the Study:

  • To develop and validate an automatic calibration method for orthognathic robot systems (ORSs).
  • To improve the accuracy and efficiency of surgical robot calibration, particularly for irregularly shaped end tools.
  • To minimize errors associated with manual calibration processes.

Main Methods:

  • Developed an automated method aligning 3D tool models to preoperative CT space for image registration and hand-eye calibration.
  • Reconstructed hand-eye-tool calibration equations using preoperative data to define tool endpoints (TEPs).
  • Employed a robust least-squares optimization method to solve transformation matrices and automated robot path planning for calibration.

Main Results:

  • Achieved a calibration error of 1.04 ± 0.54 mm in simulated experiments.
  • Reduced the total execution error to 1.56 ± 0.61 mm.
  • Demonstrated successful automation of the entire calibration process without human involvement.

Conclusions:

  • The proposed method automates surgical robot calibration, enhancing system accuracy and stability.
  • This approach is expected to facilitate more autonomous and efficient surgical procedures.
  • Future work will address limitations like marker-based tracking dependency and small sample sizes by integrating markerless tracking and machine learning.
