Abstract
Methods and apparatus are disclosed for automatic sensitivity adjustment for an autonomous mower. An exemplary mower includes a drive system and one or more cameras for capturing one or more images. One or more processors are configured to generate a grass value by applying a machine learning algorithm to the one or more images, instruct the drive system to maintain a current direction in response to determining that the grass value is greater than a mowing threshold, instruct the drive system to turn in response to determining that the grass value is less than or equal to the mowing threshold, determine a trigger rate that indicates how often the grass value is less than the mowing threshold within a predefined period of time, and decrease the mowing threshold by a predefined increment in response to determining that the trigger rate is greater than an upper threshold rate.
