Systems and devices for autonomous lawn care
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.
1. 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.
2. The autonomous lawn mower of claim 1 , further comprising a number of attachment points, the attachment points configured to receive an attachment device.
3. The autonomous lawn mower of claim 2 , wherein the attachment points comprise one or more input/output (I/O) ports to electrically couple the attachment device to the autonomous lawn mower.
4. The autonomous lawn mower of claim 2 , wherein the attachment device comprises one or more of an edging device, a string trimmer, a torch, a sprayer device, a chemical dispenser, a sensor, and a communication module.
5. The autonomous lawn mower of claim 1 , wherein the removable battery is configured to be removed without the use of a tool.
6. The autonomous lawn mower of claim 1 , wherein the removable battery is a rechargeable lithium-ion battery.
7. The autonomous lawn mower of claim 1 , wherein one or more antennas include at least one of a communication antenna and a locating antenna, the communication antenna is electrically coupled to the controller and configured to provide communication to the controller via one or more wireless protocols and the locating antenna is configured to communicate with one or more locating protocols to provide location information to the controller.
8. The autonomous lawn mower of claim 1 , further comprising a processing circuit comprising an operating and control module configured to operate the autonomous lawn mower in a plurality of operating modes based on a user input.
9. The autonomous lawn mower of claim 8 , wherein the operating modes are a plurality of pre-programmed patterns for cutting a lawn.
10. The autonomous lawn mower of claim 1 , further comprising a processing circuit comprising a coordination module configured to communicate with one or more other autonomous lawn mowers to allow for coordinated cutting of a fleet of autonomous lawn mowers at a single job site or at a plurality of job sites.
11. The autonomous lawn mower of claim 1 , further comprising:
an actuator or motor coupled to the cutting blade, wherein the controller is further configured to control the actuator or motor to change an elevation of the cutting blade to control the height of the cutting blade.
12. The autonomous lawn mower of claim 1 , further comprising:
an actuator coupled to the cutting blade, wherein the controller is further configured to control the actuator to change a pitch or angle of the cutting blade during operation.
13. The autonomous lawn mower of claim 1 , further comprising:
an actuator or motor coupled to the one or more wheels, wherein the controller is further configured to control the actuator or motor to adjust a height of the one or more wheels to control the height of the cutting blade.
