The automation of lawn mowers can eliminate many boring manual work and save labor. The focus of this article is to develop a fully automatic mowing robot. The mowing robot can be set to automatically cut off weeds in the designated area, or it can be manually controlled by wifi using a mobile phone, allowing the user to remotely control the mowing robot. We first bought a mower to modify it and completed the manual control. After that, we assembled a small robot car to simulate the automation part for the convenience of testing. The automated part uses the RTK method to get the precise GPS coordinates of the current car and the next target, and then combines the gyro sensor plus the PID to complete the straight line to reduce the overlap ratio during walking.
