WEED CONTROL WITH AN AUTONOMOUS WORK DEVICE

A weed control method for an autonomous work device is proposed, wherein the autonomous work device comprises driving means configured to move the autonomous work device in an outdoor environment. The autonomous work device further comprises sensor means configured to sense an environment of the autonomous work device and to generate a sensor signal based on the sensed environment, and a control circuit configured to control the driving means to navigate the autonomous work device in the environment based on the sensor signal. The weed control method comprises a step of obtaining a location of a target plant in the environment. The control circuit controls the driving means in a weed suppression mode, to position at least one wheel of the driving means on the computed location of the target plant and to perform a predetermined movement pattern of the autonomous work device while simultaneously maintaining the at least one wheel in an area at the location of the target plant.
