RTK helps the robot navigate using a virtual map and follow mowing trajectories consistently. This is one way to maintain a lawn without a perimeter wire.
Consider the RTK robot as a complete system
An RTK solution consists of more than just a robot with a satellite receiver. Crucial elements include correction data, its transmission, base or network service requirements, and the map. Aligning these parts helps maintain virtual boundaries and planned mowing strips. If corrections are unavailable or the position is unstable, operation depends on the specific model's additional sensors and software. This is why you should look into the system architecture beforehand. A general "RTK" label does not reveal how your chosen version will be installed.
For a practical assessment, mark problematic areas in your yard: near tall walls, dense trees, and between buildings. The manufacturer's manual will help you choose the right location for the base station, if required. It is worth reading app error messages carefully — navigation, connectivity, and charging issues require different actions. RTK is not an automatic solution for all lawn difficulties: a slippery slope or an unsuitable passageway remains a physical problem. That is precisely why a good choice includes both precise navigation and an assessment of terrain, obstacles, and installation.
How to apply this in practice?
Accurate performance depends on the availability of satellite signals and corrections. The location of the base station, buildings, and trees can have a significant impact, so the installation cannot be evaluated based solely on marketing materials.
- Find out where the model will receive RTK corrections and what is required for this.
- Check signal conditions for the base station and all work zones.
- Distinguish navigation messages from connectivity or docking station problems.
- Evaluate the model's additional sensors and permitted terrain.
Practical example
If the robot only stops by a specific building wall, the issue should be evaluated as a local navigation condition matter. If it fails to connect to the station, the entry or the contacts may be important. Both symptoms hinder mowing but should not be addressed by the same universal setting change.
When to consider LiDAR instead of RTK?
When you want to compare a different environmental assessment technology and there are challenging satellite conditions in the yard. However, a LiDAR model also has its own requirements. Base your choice on an evaluation of the specific territory and model, rather than just the technology name.
What is worth remembering?
Before purchasing, inspect the most complex areas of your yard. If the navigation is supplemented by cameras or LiDAR, find out how the model works in weaker signal zones.
