This study introduces a vision-based algorithm for quadruped robots to safely follow users, enhancing mobility support for an aging population. The system ensures reliable tracking and maintains a safe distance, paving the way for robotic walking partners.

Area of Science:

  • Robotics
  • Computer Vision
  • Human-Robot Interaction

Background:

  • Aging population requires advanced mobility and care solutions.
  • Commercial quadruped robots have limitations in safe and predictable user following.
  • Existing following modes lack necessary safety margins and consistency.

Purpose of the Study:

  • To develop a robust, vision-based algorithm for reliable person-following with quadruped robots.
  • To enhance safety and predictability in human-robot interaction for mobility assistance.
  • To address the limitations of native following modes in commercial quadruped robots.

Main Methods:

  • Utilized a ZED 2 stereo camera and Robot Operating System (ROS) on a Unitree Go1 platform.
  • Implemented a finite state machine for deterministic target tracking.

  • Employed a velocity control strategy with distinct motion zones based on depth data.

    • Main Results:

    • Achieved a mean processing latency of 66.5±4.3 ms in headless mode.
    • Demonstrated 0.0% intrusion into the intimate safety zone, ensuring user safety.
    • Maintained consistent operational stability and effective velocity synchronization (0.47-0.54 m/s).

    Conclusions:

    • The developed algorithm provides a stable technical foundation for robotic walking partners.
    • The system shows promise for assisting with mobility in aging populations.
    • Further clinical testing with elderly users is recommended for deployment.
