J100 Intelligent Flight Info/ Obstacle Avoidance Logic

Key J100 EAVision Drone Obstacle Avoidance Techniques used in Intelligent Flight, including obstacle avoidance, obstacle circumvention, obstacle crossing, terrain follow, and fixed altitude flight.

Key Drone Obstacle Avoidance Techniques

The J100 relies on advanced systems to avoid obstacles and operate safely. Below are the essential techniques used through Intelligent Flight:

Obstacle Avoidance: General methods to prevent collisions with objects.
(If flying in manual the obstacle avoidance will not let you land, as the land is seen as an obstacle. Click here for a video of how to turn the manual vertical obstacle off.)
Hovering Obstacle Avoidance: The drone stops and hovers when an obstacle is detected.
Obstacle Circumvention: The drone flies around obstacles by shifting left or right.
Obstacle Crossing: Navigates above or below objects in the flight path.
Terrain Follow: Adjusts altitude in real-time to stay at a consistent height above crops or terrain.
(If drone is not following terrain, click here for video to troubleshoot this issue.)
Fixed-Altitude Flight: Maintains a constant height regardless of ground changes.

These technologies help drones navigate safely, improving efficiency and precision in agricultural tasks.

Autonomous flight perception setting mode:

Off Intelligent bypass, off terrain following: The drone will fly at a fixed altitude and will not bypass when encountering obstacles.
On Intelligent bypass, off terrain following: The drone will bypass left and right when encountering obstacles;
Off Intelligent bypass, on terrain following: The drone will fly up and down when encountering obstacles;
On Intelligent bypass, on terrain following: The drone will prioritize flying up and down when encountering obstacles;

(If the obstacles cannot be avoided up and down, left and right, the drone will hover and wait for manual operation)

Manual flight perception setting mode:

After turning on Forward avoidance: the drone will stop and hover urgently when it is close to obstacles horizontally (adjustable from 4 to 11 meters).
After turning on Manual V-avoidance: the drone will stop and hover urgently when it is close to obstacle below (adjustable from 2.5 to 5 meters).

Note: When flying manually and landing, you need to turn off Manual V-avoidance. If it is not turned off, it will always be in the detection state and landing is not allowed.

J100 Obstacle Avoidance Guide

In a plot without obstacles, can turn off terrain following, set the operating altitude to a safe altitude, and then fly at a fixed altitude.
Do not turn on Intelligent bypass for obstacles such as windbreaks. Turning on Intelligent bypass may cause the bypass to fail and cause hovering.

There must be no wires within 8m of the plot boundary, otherwise the wires on the left and right sides may not be detected due to the limited radar vision.

Power lines

When the power line above the operating route are higher than the operating height and there are electric poles, it is necessary to turn on the Intelligent bypass function and make the route perpendicular to the power line. Because the upward field of view of the drone is limited, it is necessary to avoid the drone climbing the electric poles.
In the case of newly built black rubber shiny wires and wires with a diameter less than 1.5cm, it is recommended that the flight speed be lower than 2.5m/s, and the route planning be perpendicular to the wires to avoid the route being parallel to the wires.
In plots where it is uncertain whether obstacles can be identified, you can test at a slow speed (2m/s), no load, and at a flight altitude higher than the obstacles to observe whether the drone recognizes the obstacles.

Note: If there is a risk of collision, you can switch to manual mode in time.

Pay attention: parameter setting and route planning

Flight speed and altitude parameters (limited parameters under different states)

Flatten field: 0°~5°

Gentle Slope: 5°~25°

Steep Slope: 25°~90°

When entering and exiting a plot,

When entering and exiting plots, detours and terrain following parameters need to be set separately to avoid collisions with obstacles outside the plot. At this time, non-downward terrain following can be set to avoid the problem of excessive height difference when entering and exiting the plot.

When planning the route, it is necessary to ensure that the route is perpendicular to the wires or at an angle with the wires, so that the lidar can better scan linear obstacles. At the same time, the angle of the route can be adjusted to ensure that the route is facing the wires (this function can improve the operation efficiency)
