Abstract
A system for providing autonomous lawn care services. The system includes a number of autonomous outdoor power devices, and one or more service vehicles. The one or more service vehicles are configured to selectively load and unload one or more of the autonomous outdoor power devices at a jobsite based on instructions received by a controller of the one or more service vehicles.

An autonomous lawn mower, comprising:
- a removable battery having a capacity of at least 800 Watt-hours;
- a plurality of sensors;
- one or more wheels;
- a cutting blade;
- one or more antennas;
- a controller configured to allow the autonomous lawn mower to perform a grass cutting function at a jobsite and to control a height of the cutting blade without human interaction;
- one or more motors;
- and
- at least one of an accelerometer and a gyroscope;
- wherein the controller is further configured to:
- determine whether a roll angle is greater than a first predefined amount, wherein the roll angle is measured from at least one of the accelerometer and the gyroscope;
- in response to determining the roll angle is greater than the first predefined amount, stop operation of one of the one or more motors configured to provide rotational drive power to the cutting blade;
- and
- wherein the controller is further configured to:
- determine whether the roll angle is greater than a second predefined amount;
- and
- in response to determining the roll angle is greater than the second predefined amount, stop operation of each of the one or more motors.
