    Area of Science:

    • Biotechnology
    • Zoology
    • Computer Science

    Background:

    • Accurate, real-time tracking of multiple small organisms is essential for behavioral studies.
    • Existing methods may lack the precision or capacity for simultaneous multi-subject analysis.

    Purpose of the Study:

    • To describe a novel system for simultaneous, high-frequency tracking of multiple animals.
    • To demonstrate the system's utility in studying nematode chemotaxis.

    Main Methods:

    • Development of a tracking system utilizing a 6809 microprocessor and OS-9 operating system.
    • Implementation of application programs in assembly and BASICO9 languages.
    • Real-time determination and display of subject positions at a rate of one per second for up to 25 animals.

    Main Results:

    • The system successfully tracks approximately 25 animals simultaneously.
    • Position data is updated once per second, enabling real-time movement analysis.
    • The system effectively displays movements and direction changes.

    Conclusions:

    • The developed system provides a valuable tool for studying nematode chemotaxis.
    • The technology is adaptable for research on other small animals observable with high contrast.
