Autonomous lawn mower

A method of preparing a lawn mower for operation, the lawn mower comprising a chassis, a blade, and a podium having an upper portion and a lower portion, the upper portion being removably coupled to the lower portion and comprising a plurality of sensors comprising one or more of cameras, an inertial measurement unit (IMU), a Global Navigation Satellite System (GNSS) receiver, and an antenna for wireless communication, the method comprising:

• determining calibration data associated with the plurality of sensors;
• and
• coupling, subsequent to determining the calibration data, the upper portion to the lower portion;
• and
• transmitting the calibration data to one or more processors associated with the lower portion.

A autonomous lawn mower comprising:

• a chassis;
• a blade;
• and
• a podium having an upper portion and a lower portion, the upper portion being removably coupled to the lower portion and comprising:
• a plurality of cameras,
• an inertial measurement unit (IMU),
• a Global Navigation Satellite System (GNSS) receiver, and
• an antenna for wireless communication,
• the lawn mower further comprises one or more non-transitory computer readable media which, when executed by one or more processors, cause the one or more processors to perform operations comprising:
• receiving, upon coupling the upper portion to the lawn mower, calibration data;
• and
• controlling the lawn mower based at least in part on the calibration data.
