Title:
DRONE DEVICE FOR COATING AND COATING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/057825
Kind Code:
A1
Abstract:
[Problem] To provide a drone device for coating and a coating method capable of performing maintenance coating safely and inexpensively. [Solution] The drone body part 10 has an IMU 15 that acquires the tilt angle of a drone device 1, a GPS receiver 16 that acquires the location coordinates of the drone body part 10, a distance sensor 18 that calculates the coating distance from the drone body part 10 to the coating target, and a control unit 14 that changes the position of the drone body part 10 and changes the nozzle angle of a nozzle 341 based on the current tilt angle of the drone body part 10 and the coating distance. The spray control unit 142 that constitutes the control unit 14 computes the discrepancy in the nozzle spray direction arising due to the acquired tilt angle and computes correction of the nozzle angle in the up/down and right/left directions by taking into consideration offset of the nozzle position in the vertical/horizontal directions arising due to the distance between the roll center of the drone body part 10 and the nozzle 341.
