What it solves

It transforms basic, "dumb" robotic lawn mowers—which typically move in random patterns until they hit a boundary—into intelligent, GPS-guided machines. It eliminates the need for physical perimeter wires and allows for precise, map-aware autonomous mowing.

How it works

OpenMower replaces the original hardware "brain" of a compatible mower (such as the YardForce Classic 500) with a custom open-source hardware and software stack. The system uses ROS (Robot Operating System) for navigation, planning, and state management, combined with RTK GPS for precise positioning. It includes a dedicated operating system image, custom firmware for motor control and sensors, and a mobile/web app for user control.

Who it’s for

DIY enthusiasts with intermediate skills in electronics, Linux, and mechanics who want to build a low-cost, smart autonomous mower.

Highlights

• No Perimeter Wires: Uses GPS guidance instead of physical boundary cables.
• Obstacle & Weather Awareness: Includes features to detect and avoid obstacles and pause mowing during rain.
• Safety First: Integrated emergency stops for when the robot is lifted or crashes.
• Modular Ecosystem: Split into dedicated repositories for ROS navigation, firmware, hardware designs, and a control app.
