- Commodity name: R21-1 Obstacle Avoidance Radar on Drone
UAV-R21-1 drone obstacle avoidance radar is a kind of tiny millimeter wave radar which is self-designed by Microbrain. It can guide the drone to avoid front obstacles automatically to ensure its work safety during flight.
Product Details
R21-1 77GHz-81GHz millimeter wave obstacle avoidance radar is mounted on farming agriculture drone front/rear. It can detect obstacles and keep obstacle avoidance automatically during drone flying.
This radar tell whether there’s obstacle in front by sending fan-shaped 79GHz electromagnetic wave forward and processing returned signals. By using the 79GHz high frequency band millimeter wave radar, the radar will get data feedback about the relative distance from obstacle to radar, the speed and the angel, then finally guide the drone to avoid the obstacles and ensure work safety.
Product Features
● 1.5~27m obstacle detection;
● CAN connect interface;
● Adapt to Pixhawk / Ardupilot flight controller;
● IP67 protect level;
● Tiny body with only 105g.
