## What it is
OpenMower is an open-source project that converts cheap off-the-shelf robotic lawn mowers into smart, RTK GPS-guided mowing robots by replacing their stock electronics with custom hardware and software. It provides autonomous, map-aware, app-controlled lawn mowing without perimeter wires, with obstacle avoidance and safety features.

## Use cases
- convert a cheap robotic mower into a smart GPS-guided robot
- mow the lawn without installing perimeter wire
- build a DIY autonomous lawn mowing robot
- add RTK GPS navigation to a YardForce mower
- control a mowing robot from a mobile app
- detect and avoid obstacles while mowing

## When to choose
- you want a wire-free, GPS-guided robotic mower at lower cost than premium commercial models
- you enjoy DIY hardware projects and are comfortable modifying electronics
- you want an open, hackable robot lawn mower with app control and obstacle avoidance

## When to avoid
- you are not comfortable with hands-on hardware modification and electronics work
- you want a plug-and-play commercial product with warranty and support
- you need a solution cheaper than ~€700 plus the base mower and RTK station

## Facets
- artifact type: application
- maturity: active
- function: robotics, monitoring
- domain: robotics, iot, hardware
