UAV Obstacle Avoidance
Release time:
2026-03-12

Application Overview
Drone obstacle avoidance enables UAVs to detect and avoid obstacles during autonomous flight. By using onboard sensors, drones can monitor their surroundings in real time and identify potential hazards along the flight path.
When an obstacle is detected, the flight controller automatically commands the drone to hover or adjust its flight path, ensuring safe and continuous operation.
Solution
Nanjing Surertech Intelligent Technology Co., Ltd. provides the VB Series LiDAR modules for UAV obstacle avoidance. With detection ranges of 20 m and 50 m, these sensors enable drones to detect obstacles early and respond quickly during flight.

Flexible & Easy to Install
Adaptable for different setups and system expansions.
Cost-Effective Solution
High performance at an affordable price.
Obstacle Avoidance for UAV: Typical Installation Methods of VB50A
1. Top Installation
The LiDAR can be integrated with a servo module to form a single unit.
By controlling the rotation of the servo, the VB50A performs single-point scanning, enabling dynamic obstacle detection during flight.

2. Embedded Multi-Directional Installation
The VB50A series LiDAR sensors can also be embedded into the drone fuselage for fixed installation. Multiple sensors can be arranged in different directions to achieve comprehensive obstacle detection.
Typical configurations include:
Six-direction installation: Sensors mounted on the top, bottom, left, right, front, and rear sides of the drone, enabling full spatial obstacle detection.

Four-direction installation: Sensors mounted on the front, rear, left, and right sides of the drone, providing multi-directional obstacle avoidance.
