The Holy Stone Hs720g is a popular drone among enthusiasts and beginners alike. Its advanced features include obstacle avoidance technology, which is crucial for safe and efficient flying. In this article, we will explore how the Hs720g performs in obstacle avoidance during flight tests.

Overview of the Holy Stone Hs720g

The Holy Stone Hs720g is equipped with GPS positioning, a 4K camera, and intelligent flight modes. Its obstacle avoidance system uses sensors located on the front, back, and sides of the drone to detect objects in its path. This feature aims to prevent collisions and make flying more accessible for users of all skill levels.

Obstacle Avoidance Technology

The drone's obstacle avoidance system employs infrared sensors and ultrasonic sensors to detect nearby objects. When an obstacle is detected, the drone's flight controller automatically adjusts its course or hovers in place to avoid a collision. This system is designed to work in various environments, including indoor and outdoor settings.

Sensor Placement and Functionality

The sensors are strategically placed on the front, rear, and sides of the drone. The front sensors are primarily responsible for obstacle detection during forward flight, while the rear sensors activate during backward movement. Side sensors help prevent collisions during lateral maneuvers.

Flight Test Results

During flight tests, the Holy Stone Hs720g demonstrated effective obstacle avoidance capabilities. When approaching objects at moderate speeds, the drone successfully detected obstacles and either slowed down or changed direction. In some cases, the drone hovered in place to reassess its surroundings before proceeding.

In outdoor environments with trees and other natural obstacles, the drone's sensors responded well, preventing collisions. However, in cluttered indoor spaces, the obstacle avoidance system occasionally struggled with small or low-contrast objects, highlighting some limitations.

Limitations and Considerations

  • Sensor range is limited; very close or very far objects may not be detected.
  • Small or transparent obstacles can sometimes be missed.
  • Rapid maneuvers may reduce obstacle detection effectiveness.
  • Environmental conditions like fog or rain can impair sensor performance.

Conclusion

The Holy Stone Hs720g's obstacle avoidance system provides a valuable safety feature that enhances the flying experience. While it performs well in many scenarios, users should remain cautious and maintain visual line-of-sight, especially in complex environments. Overall, the drone's obstacle detection capabilities make it a solid choice for those seeking a reliable and user-friendly flying camera.
