This study introduces a two-grade interpolation algorithm for high-intensity focused ultrasound (HIFU) robots. The method enhances coordinated dynamic performance for precise robotic movements.

Area of Science:

  • Robotics
  • Medical Engineering
  • Control Systems

Context:

  • High-intensity focused ultrasound (HIFU) requires precise robotic control.
  • Serial-parallel robots present unique kinematic and dynamic challenges.
  • Existing interpolation schemes may not meet stringent dynamic performance requirements.

Purpose:

  • To develop a novel 2-grade interpolation algorithm for HIFU serial-parallel robots.
  • To address the dynamic performance limitations of current robotic interpolation methods.
  • To provide a detailed procedural description of the proposed interpolation algorithm.

Summary:

  • A 2-grade interpolation algorithm, comprising rough and fine stages, is presented for HIFU serial-parallel robots.
  • The algorithm incorporates pre-acceleration and post-acceleration techniques.
