AI Technical Summary

Technical Problem

Existing zooplankton sampling methods are inefficient and cannot accurately pinpoint the sampling location, resulting in low sampling accuracy.

Method used

A zooplankton sampling device for marine biological surveys was designed. It uses vertical and horizontal propellers in conjunction with a controller and camera navigation to enable the device to move freely underwater and accurately locate sampling points. The opening and closing of the sample inlet gate is controlled by a baffle motor, the light source controller attracts zooplankton, and the cooperation of the filter and the sample outlet gate ensures the purity and activity of the sample.

Benefits of technology

This improved the accuracy and authenticity of sampling, ensured the purity of the samples and the activity of zooplankton, and increased the efficiency of sample collection for staff.
