Reactive Behaviors and Algorithms
Upon detecting an obstacle, the mower must execute a pre-programmed reactive behavior. This may involve stopping, altering its trajectory, or performing a combination of both. The algorithms that govern these reactive behaviors are critical to avoiding collisions and ensuring the mower continues its mowing cycle efficiently. For instance, upon detecting a child’s toy, the mower should halt and change direction to avoid running over the object. Similarly, when encountering a tree, the mower should navigate around its base to ensure complete lawn coverage.
-
Sensitivity Adjustment and Customization
The sensitivity of the obstacle detection system must be adjustable to accommodate different lawn environments. A lawn with numerous small objects, such as rocks or fallen branches, may require lower sensitivity to prevent the mower from constantly stopping.
