Autonomous Boxfish AUV Demonstrates Efficiency in Freshwater Survey Missions

Boxfish Robotics R&D team has taken another big step in advancing the autonomous capabilities of the Boxfish AUV. As part of our phased validation approach, we recently conducted a successful mission in Lake Pupuke, New Zealand, a freshwater crater lake ideal for controlled demonstrations.

Mission Overview

Using Boxfish Mission Planning Software Safepath, we programmed the AUV to perform a 15 × 15 m grid survey at an altitude of 1.7 m, travelling at a speed of 0.3 m/s. The result? A highly detailed 3D model of the lakebed, created from over 800 overlapping images captured in a single 26 minute run.

This tightly packed visualisation of image overlap illustrates the precision and efficiency of the coverage is an essential foundation for reliable photogrammetry, habitat analysis, and environmental monitoring.

Scientific Value of the Mission

This mission demonstrates the AUV’s ability to autonomously:

• Navigate pre-planned paths with high spatial accuracy
• Maintain stable altitude and speed throughout the mission
• Capture data suitable for scientific-grade 3D reconstruction

For researchers, environmental agencies, and marine consultants, this test shows the potential of Boxfish AUV for:

• Lake and shallow water surveys
• Baseline habitat mapping
• Monitoring change over time

Towards Greater Impact

The next phase of our programme brings the AUV into coastal and open ocean environments, where we will showcase performance in more dynamic conditions and larger-scale missions. Later this year, we plan to collaborate with partners on real-world applications, including coral reef surveys.

Stay tuned as we expand the envelope of autonomous underwater exploration.
