Abstract: An autonomous lawn mower includes removable batteries, one or more electric motors, a cutting blade, one or more wheels, an angle sensor, and a controller. The cutting blade is driven by one of the electric motors. The wheels are driven by one of the electric motors. The controller is configured to allow the lawn mower to perform a grass cutting function at a jobsite without human interaction. The controller is configured to determine whether a roll angle is greater than a first predefined amount using data from the angle sensor. In response to determining the roll angle is greater than the first predefined amount, the controller is configured to stop operation of one of the one or more electric motors configured to provide rotational drive power to the cutting blade.
