Warning
1. The Obstacle Avoidance Radar is only compatible with the AGRAS
TM
MG-1S. DO NOT use it with
other products.
2. The Obstacle Avoidance Radar can be used with at farmland only and cannot be used with slope
elds where height dierences may occur.
3. To avoid interference, ensure that there is no other equipment using microwave radio frequencies
nearby. For example, automotive microwave radars, satellite communication stations, etc.
4. Before use, ensure that the outer protective cover is not cracked, chipped, sunken, or misshapen.
5. Keep the protective cover clean. Clean the surface with a soft damp cloth and air dry before using
again.
6. The obstacle avoidance functions are disabled in A-mode (Attitude).
7. Obstacle avoidance is adversely aected when aircraft pitch exceeds 15°. Please y with care.
8. Obstacle avoidance is disabled when ying over surfaces at a height of < 0.8 m.
9. Aircraft speed should not exceed 5 m/s when ying over surfaces at a height of < 2 m. Aircraft
speed should not exceed 7 m/s when ying at a height of ≥ 2 m. Obstacle avoidance will otherwise
be greatly compromised or even disabled.
10. Please maintain full control of the aircraft at all times. DO NOT rely solely on the DJI MG app. Keep
the aircraft within a visual line of sight observing it at all times. Use your discretion to operate it
manually to avoid obstacles.
11. DO NOT attempt to disassemble any part of the Obstacle Avoidance Radar that has already been
mounted prior to shipping.

Introduction
The Obstacle Avoidance Radar is compatible with the Agras MG-1S. Microwave technology means
the radar is fully operational in dusty, misty, or nighttime conditions. It enables the aircraft to sense
obstacles in front of or behind it within 30 meters (refer to Specications for details), improving operation
safety. The DJI MG app will display obstacle information according to the orientation of the aircraft. A
built-in stabilized gimbal means that attitude changes cause no interference to the detection of angles.
Additionally, front and rear obstacle detection can be switched when ying forward or backward.

Aircraft Actions
1. If obstacles are detected more than 6 m away from the aircraft during ight, it will slow down and
hover in place about 6 m away from the obstacle.
2. If obstacles are detected within 6 m from the aircraft during ight, the aircraft will immediately brake
and hover in place. Braking distance is required when stopping mid-ight. Observe the distance
between an obstacle and the aircraft at all times. If necessary, y in a dierent direction than the
obstacle to avoid a collision.
3. When the aircraft is in Smart Operation Mode (A-B Route) or F-mode (Route), it will pause the current
task and record a break point when slowing down. Users can resume operation after controlling the
aircraft to avoid the obstacles. Refer to the “Operation Resumption” section in “MG-1S User Manual”
for more details.
Disable Obstacle Avoidance Functions
When not in use, disable the obstacle avoidance functions in the DJI MG app. To do this, enter
Operation View, tap on top of the screen, then turn off the Obstacle Avoidance Radar in
Aircraft Settings.

简 介
高精度雷达避障模块是一款适用于 DJI MG-1S 农业植保机的配件，采用微波测距技术
实现障碍物感知，可适应尘土、喷雾等恶劣作业环境，且支持夜间作业。避障模块根据
飞行器飞行方向可感知前方或后方 30 m 内的障碍物（详见规格参数），并在 DJI MG
App 中显示相应信息，以提升植保作业的安全性。内置增稳云台确保雷达探测角度不受
飞行器姿态变化的影响，同时根据飞行器前飞或后飞切换前方或后方障碍物探测。

飞行器动作
1. 飞行过程中，若在距飞行器 6 米外的探测范围检测到障碍物，则飞行器将减速，
然后在距离障碍物约 6 米处悬停。
2. 飞行过程中，若在距飞行器 6 米内的探测范围检测到障碍物，则飞行器将立即刹
车至悬停。飞行器完全停止需要一定的刹车距离，在此情况下用户应时刻关注飞
行器与障碍物的距离，必要时可操控飞行器向反方向飞行，以免发生碰撞。
3. 若飞行器处于智能作业模式（A-B 点作业）或 F 模式（航线作业），则减速过程中
飞行器暂停当前任务并记录中断坐标点。用户操控飞行器绕过障碍物后，可进行
作业恢复，详见《MG-1S 用户手册》的“作业恢复”章节。
关闭避障功能
若不使用避障功能，可在 App 中关闭。进入 App 作业界面，点击右上方的 图标，
在 植保机参数中关闭避障模块。
