Abstract/Summary

Grass lawns are a common hallmark of the American home. In 2019, a survey from the National Association of Landscape Professionals found that 81% of all Americans owned a lawn [1]. Mowing is a time consuming and costly chore that is part of maintaining a grass lawn. The manual labor in mowing a lawn can exceed 40 hours per year [2]. People commonly incur weekly costs on mowing services to save time. Traditional gas powered mowers are physically demanding and use engines that need routine maintenance. They operate loudly enough that users should be wearing hearing protection and the noise commonly disturbs neighbors. Air pollution from gas emissions are also a concern for both the user and for the environment.

An electric autonomous mower utilizes rechargeable batteries for power. Without a gas-engine, it is significantly quieter and requires little maintenance. No user is necessary to push the mower and there are no gas emissions. The mower returns to a docking station for charging its self-contained battery and leaves to mow as scheduled by the user. Collision avoidance and object detection are part of the mower’s completely autonomous navigation. These features allow the user to spend their time freely after the initial setup. Additional functionality such as blade mowing patterns and routine check-up reminders can be controlled through a wireless remote interface.
