Ultrasonic Sensors
Ultrasonic sensors emit high-frequency sound waves and measure the time it takes for the waves to return after hitting an object. This method is effective for detecting obstacles in the mower’s path, allowing it to slow down or change direction before collision. In the context of “testsieger mahroboter ohne begrenzungskabel 2024,” mowers equipped with advanced ultrasonic systems demonstrate a heightened awareness of their surroundings, reducing the risk of damage to garden ornaments, trees, or pets. For example, models with a wider detection range and faster processing speeds can react more effectively to moving objects, such as children or animals playing in the yard.
-
Computer Vision and Camera Systems
Computer vision systems utilize cameras to analyze the mower’s surroundings, enabling it to identify and classify objects with a higher degree of accuracy. This approach allows the mower to differentiate between various obstacles, such as flowers, trees, or sidewalks, and respond accordingly. High-resolution cameras, coupled with sophisticated image processing algorithms, empower mowers to make informed decisions, avoiding not only physical obstructions but also areas deemed off-limits, such as flower beds or vegetable gardens. Mowers with advanced vision systems exemplify the “testsieger” criteria by providing a more nuanced and adaptable approach to obstacle avoidance.

Bump Sensors and Physical Contact Detection
While less sophisticated than ultrasonic or camera-based systems, bump sensors provide a basic level of obstacle detection by registering physical contact with an object. When a bump sensor is triggered, the mower typically stops and changes direction. Although this method is effective for preventing damage from direct collisions, it lacks the proactive avoidance capabilities of more advanced systems. Mowers relying solely on bump sensors may still qualify for the “testsieger” designation if they demonstrate exceptional performance in other areas, but their obstacle detection capabilities are generally considered less advanced than those of models incorporating ultrasonic or camera technology.
