Claim Text:
1. A method of coating a sealant composition to an inner surface of a tire, the method comprising: extracting coordinates for coating a sealant composition with reference to a central point of a target tire using a computer-aided design (CAD) file of the target tire; setting robot moving coordinates and setting a coating width based on the extracted coordinates; and ejecting the sealant composition by a nozzle provided to a robot arm, wherein the robot arm is moved according to the set coordinates, wherein a distance between a distal end of the nozzle and a central axis of the tire is measured by a distance sensor and transmitted for feedback to a robot controller to control the nozzle to move at a constant linear speed based on the transmitted data in order to uniformly coat the sealant composition to the inner surface of the tire.
