The invention discloses a precise variable
fruit tree pesticide application
robot based on multiple sensors. The
robot comprises a self-propelled
system, a
laser sensor (10), a camera (11), an industrial
personal computer and a
single chip microcomputer (9); the self-propelled
system is used for installing equipment and driving the whole
robot to move forward; the
laser sensor (10) is used for detecting whether or not a target exists, sending a
signal to the industrial
personal computer after the target is detected and collecting and transmitting distance information to the industrial
personal computer; the camera (11) is used for collecting images of the target and transmitting the images to the industrial personal computer for
processing; the industrial personal computer is used for receiving the
target signal of the
laser sensor (10), judging the
disease level according to the collected image information, obtaining the total
canopy volume of the target according to the distance information of the target to determine the
pesticide spraying amount and transmitting the
pesticide spraying amount information to the
single chip microcomputer (9); the
single chip microcomputer (9) is used for receiving the pesticide spraying amount information, controlling a pesticide supply
system to supply pesticide to a variable spraying system and controlling the variable spraying system to apply the pesticide. The robot obtains the accurate pesticide spraying amount by accurately detecting the volume of the target and identifying the degree of diseases and pests.
