Vision navigation technology allows the robotic lawnmower to navigate in space using the built-in camera. The camera senses the mower's surroundings and specialised software, which often uses artificial intelligence features, analyses the image and recognises different surfaces and objects. This allows the mower to identify where the lawn to be mowed is and where, for example, a flower bed, patio or other obstacle begins. The main purpose of this technology is to allow the mower to operate without the need to install perimeter wire, which physically defines the working area in older models. Based on visual data, the mower either creates a virtual map of the garden or decides its route in real time based on what it "sees" in front of it. The system's functionality can be affected by lighting conditions such as direct sun or deep shade, and requires clearly visible boundaries between the lawn and other areas.
