Robot lawn mower without boundary wire and without RTK: the third generation of lawn care
No wire to bury, no RTK antenna to mount: robot lawn mowers without boundary wire and without RTK navigate purely visually using an AI camera. This guide explains how the technology works, where its strengths lie compared with RTK-GPS – and which gardens it is the best choice for.
Three generations of robot lawn mower navigation
Generation 1 – boundary wire: A live wire is buried around the lawn. Drawbacks: laborious installation, wire breaks, no systematic lanes (chaos principle).
Generation 2 – RTK-GPS: A reference antenna in the garden corrects the satellite signal to within 2–3 cm. Works well on open areas – but: trees, roof overhangs and house walls block the signal. In winding or tree-rich gardens the robot stops. The antenna needs a mounting spot with a clear view of the sky, plus power.
Generation 3 – AI vision: Cameras + AI recognise lawn, edges and obstacles directly – just like a human. No wire, no antenna, no signal dropouts. The TerraMow V600 and V1000 map the garden fully automatically on their first run and then mow in clean, systematic lanes.
Vision vs. RTK: the direct comparison
| Criterion | AI vision (TerraMow) | RTK-GPS | Boundary wire |
|---|---|---|---|
| Installation | 5–10 min, charging station only | Mount antenna + calibrate | Bury wire (hours/days) |
| Trees / overhead cover | No problem | Signal dropouts possible | No problem |
| Winding gardens | Well suited | Limited | Laborious |
| Obstacle detection | 3D camera, detects hedgehogs & toys | Usually only bump sensor/ultrasound | Bump sensor |
| Cutting pattern | Systematic lanes | Systematic lanes | Random pattern |
| Follow-up costs | None | Antenna accessories | Wire repairs |
Which gardens is a robot lawn mower without RTK ideal for?
- Gardens with trees and shrubs: where RTK signals cut out, the camera simply keeps seeing.
- Winding plots: multiple zones, narrow passages, front and back garden – the visual map makes it possible.
- Rented gardens & new lawns: nothing is buried or permanently mounted; simply take it with you when you move.
- Anyone who doesn't want an antenna in the garden: no compromises on looks, no extra power cable to the antenna.
Frequently asked questions (FAQ)
Which robot lawn mower works without a boundary wire and without RTK?
Camera-based robot lawn mowers such as the TerraMow V600 (up to 600 m², 899 €) and TerraMow V1000 (up to 1,200 m², 1,199 €) navigate purely visually using AI – with no wire in the ground and no RTK antenna in the garden.
What is the downside of RTK robot lawn mowers?
RTK needs a clear line of sight between the reference antenna and the robot. Trees, roof overhangs, house walls or carports interrupt the signal – the robot stops or mows incompletely. In addition, the antenna has to be mounted and supplied with power.
How does a robot lawn mower navigate without RTK and without a wire?
Via an AI camera system: using three cameras (TerraVision™), the TerraMow recognises lawn areas, edges and obstacles, maps the garden automatically on its first run and then mows in systematic lanes.
Is a camera-based robot lawn mower reliable in poor light?
The TerraMow mows reliably in daylight and at dusk; in the dark it pauses by default – which also protects hedgehogs and other nocturnal animals.
How much does a good robot lawn mower without boundary wire and without RTK cost?
The TerraMow V600 costs 899 € (RRP 999 €) including a garage, 27 spare blades and a 4G module for 1 year. The larger V1000 for up to 1,200 m² costs 1,199 €.
