The Holy Stone Hs720G drone has gained popularity among both amateur and experienced pilots. Its advanced features include a GPS system, 4K camera, and an anti-collision system designed to enhance safety during flight. This article explores the effectiveness of the anti-collision system based on a series of flight tests.

Overview of the Holy Stone Hs720G Anti-collision System

The anti-collision system in the Holy Stone Hs720G utilizes sensors positioned around the drone to detect obstacles in its flight path. When an obstacle is detected, the system can automatically stop, slow down, or navigate around the object. This feature aims to prevent crashes and improve flight safety, especially in complex environments.

Flight Test Setup

The flight tests were conducted in various environments, including open fields, urban areas, and indoor spaces. The drone was flown at different speeds and altitudes to evaluate the anti-collision system’s responsiveness and reliability. Multiple obstacles such as trees, poles, and walls were used to simulate real-world scenarios.

Test in Open Field

In open areas, the drone demonstrated smooth navigation with minimal false detections. When approaching stationary objects like trees, the anti-collision system effectively slowed the drone and altered its course, avoiding collisions in most cases. The system’s reaction time was approximately 1-2 seconds, which is adequate for open-field flying.

Urban Environment Test

In urban settings, the drone encountered more complex obstacle patterns. The anti-collision system successfully detected and avoided larger obstacles such as building edges and poles. However, in tight spaces with multiple small obstacles, the system occasionally failed to detect some objects, leading to near-misses. This indicates that while effective, the system has limitations in cluttered environments.

Indoor Flight Performance

Indoor flights tested the system’s ability to handle obstacles like walls, furniture, and hanging objects. The anti-collision sensors performed well in detecting larger obstacles, prompting the drone to stop or change course. However, small objects like thin wires or narrow gaps were sometimes missed, which could pose risks in confined spaces.

Overall Effectiveness and Limitations

The Holy Stone Hs720G’s anti-collision system provides a significant safety feature, especially for beginner pilots or those flying in unfamiliar environments. It effectively detects and avoids larger obstacles in most scenarios, reducing the risk of crashes. However, its limitations in detecting small or multiple obstacles highlight the need for cautious flying and supplementary manual control.

Conclusion

The anti-collision system in the Holy Stone Hs720G is a valuable addition that enhances flight safety. While not infallible, it performs well in open and semi-urban environments, making it suitable for casual and semi-professional use. Users should remain vigilant, especially in cluttered or indoor spaces, to ensure safe operation.
