AI Technical Summary

Technical Problem

The existing technology lacks the optimized design of the center of gravity of the drone, which leads to unstable flight when load changes, which may lead to problems such as slow handling response, reduced stability and easy rolling.

Method used

A pre-hospital emergency drone distribution system is designed, including a drone platform, center of gravity detection unit, inertia detection unit and center of gravity adjustment strategy unit. The position of the load box is dynamically adjusted through the center of gravity adjustment mechanism (including X-axis slide rail assembly, Y-axis slide rail assembly and rotating platform) to ensure that the center of gravity of the drone is always within the preset range.

Benefits of technology

By dynamically adjusting the position of the load box, precisely controlling the center of gravity of the drone, the problem of flight instability caused by load changes is avoided, the safety and reliability of the flight is significantly improved, the battery life of the drone is extended, and the dependence on high-precision sensors is reduced.
