Slopes, pits, and uneven surfaces reduce a robot's operating efficiency. Slippery grass and saturated soil further complicate traction. Choosing solely based on the maximum permissible slope is not enough.
At the slope, the boundary and the conditions near it are important
Conquering a slope depends on more than just the maximum gradient specified by the manufacturer. A dry, even slope and the same gradient on wet, uneven grass can result in entirely different traction. Check where the slope begins and ends, whether there is room for turns, and if there are risky obstacles at the bottom. The robot must not only be able to climb but also move safely, turn around, and stay within boundaries. If an area is constantly slippery, a more powerful model alone will not change the soil and lawn conditions.
When comparing parameters, it is essential to distinguish percentages from degrees. For example, a 30 percent slope means a 30 cm rise over 1 m of horizontal distance, not a 30-degree angle. Also, the manufacturer may specify different requirements for the interior of the work area and at its boundary. When buying an inexpensive model, do not overlook these details: proper traction and stable operation must be essential criteria. If the plot has particularly steep or dangerous sections, they may require a different maintenance strategy rather than pushing the robot to the limit of its capabilities.
How to apply this in practice?
Wheels, weight distribution, navigation, and safe distance to boundaries are important. The maximum slope within the work area may differ from the allowed slope at the edge.
- Measure the slope and correctly compare percentages and degrees.
- Check the manufacturer's requirements for work and boundary zones.
- Evaluate moisture, unevenness, turns, and the area at the bottom of the slope.
- Do not plan operation beyond the documented limits of a specific model.
Practical example
A slope may be small, but a narrow strip near a pond at its bottom makes the route complicated. Such an area should not be evaluated solely based on the incline. Safe distances and physical protection requirements must be observed, and in case of doubt, an alternative maintenance method should be planned.
Does navigation technology improve traction on its own?
No. Navigation helps determine location and route, while traction is determined by the chassis and the surface. When choosing, evaluate both aspects together, but do not replace terrain requirements with the promise of more advanced navigation.
What is worth remembering?
Measure the most difficult areas of your plot and compare them with the model's manual. If conditions are near the limit, choose a greater safety margin or change the work zone.
