Area of Science:

  • Robotics
  • Computer Vision
  • Artificial Intelligence

Background:

  • Quadrupedal robots require advanced perception for autonomous navigation in unstructured environments.
  • Visual perception offers a cost-effective approach compared to multi-sensor systems for robotic autonomy.

Purpose of the Study:

  • To propose an image segmentation-guided visual tracking framework for quadruped robots.
  • To enhance both the perceptual capabilities and motion control of bio-inspired robots.

Main Methods:

  • Developed a cascaded convolutional neural network with a global information guidance module for image segmentation.
  • Integrated segmentation outputs into a biologically inspired central pattern generator (CPG) for motion control.
  • Created a closed-loop visual-motor system for dynamic environmental adaptation.

Main Results:

  • Achieved enhanced segmentation precision, particularly under visually degraded conditions.
  • Demonstrated improved motion flexibility and coordinated limb/spinal trajectory generation.
  • Experimental results show superior performance over existing methods in segmentation and locomotion tasks.

Conclusions:

  • The proposed framework effectively enhances visual perception and motion control in quadruped robots.
  • Vision-guided control strategies show significant potential for real-time robotic navigation applications.
