Purpose of the Study:

  • To develop an optimized area coverage path planning approach for microrobots.
  • To address environmental uncertainties in controlled drug delivery.

Main Methods:

  • Proposed a genetic algorithm (GA)-based area coverage approach.
  • Integrated online and offline path planning for adaptability.
  • Implemented an expandable chromosome concept for efficient path selection based on length and turning angles.

Main Results:
