wherein the front radar allows the drone to detect and avoid collisions;

wherein the drone utilizes the front radar, and the LiDAR sensor cooperatively to detect and avoid obstacles;

wherein for liquid application, the drone comprises a pair of primary spray nozzles located beneath the rear rotors;

wherein the pair of primary spray nozzles is supplemented by a pair of secondary spray nozzles added beneath the front rotors.

2 . The agricultural chemical application drone according to claim 1

wherein the drone comprises the plurality of rotors, a motor speed controller, a motor control, a plurality of carbon fiber arms, one or more landing skids, and a chassis made of aluminum;

wherein an individual rotor selected from the plurality of rotors comprises a motor and a propeller at the end of an individual carbon fiber arm;

wherein the chassis comprises a rectangular tubular mounting system and arms that can be folded to decrease the size of the drone.

3 . The agricultural chemical application drone according to claim 2

wherein the plurality of rotors comprise four rotors;

wherein the payload is 150 kg.

4 . The agricultural chemical application drone according to claim 2

wherein a battery selected from a 30 Ah battery and a 40 Ah battery, both waterproof, powers the drone.

5 . The agricultural chemical application drone according to claim 4

wherein the computer processor performs all calculations, including the trajectory, real time kinematics, height determination, and other functions of the drone.

6 . The agricultural chemical application drone according to claim 5

wherein the spraying system comprises the tank to hold an agricultural chemical;

wherein the tank is at least a 60-liter tank for a liquid chemical.

7 . The agricultural chemical application drone according to claim 6

wherein the tank is at least a 100-liter tank for sowing a solid chemical;

wherein the 100-liter tank has a maximum load capacity of 80 kg.

8 . The agricultural chemical application drone according to claim 7 wherein the perception system comprises a LiDAR sensor located on the front of the drone;

wherein the computer processor receives the data from the LiDAR sensor;

wherein the computer processor calculates distances from the LiDAR sensor and determines the distance of the items present through the process of stereo vision;

wherein with these two distance inputs, the computer processor performs obstacle detection, allowing the drone to swerve or avoid an accident.
