When a Roomba encounters an object, it typically goes through a series of actions designed to navigate around or interact with the obstacle. Here's what typically happens:
Detection: Roombas are equipped with various sensors, such as infrared sensors, bump sensors, and sometimes cameras or LIDAR (Light Detection and Ranging) sensors. These sensors help the Roomba detect obstacles in its path.
Bump and Redirect: When the Roomba physically touches an obstacle, the bump sensors detect the impact and trigger a response. The Roomba will then change its direction and continue cleaning in a different path to avoid the obstacle.
Infrared Detection: Infrared sensors help the Roomba detect walls and larger objects without making physical contact. When it senses an object or a wall, it will adjust its path to avoid hitting it.
Virtual Walls: Some Roomba models come with virtual wall barriers. These devices emit an infrared signal that creates an invisible barrier the Roomba won't cross, helping to keep it away from certain areas or delicate objects.
LIDAR or Camera-Based Detection (Advanced Models): High-end Roomba models may be equipped with LIDAR or cameras that provide more sophisticated obstacle detection and mapping capabilities. They can detect objects with greater precision and create detailed maps of the environment to navigate around obstacles more efficiently.
Cautious Navigation: Roombas are designed to navigate with some degree of randomness, and when they encounter an obstacle, they typically slow down and navigate cautiously to avoid collisions.
Trying Different Angles: If the Roomba repeatedly encounters the same obstacle, it may attempt to approach it from different angles to find a clear path around it.
Edge Detection: Roombas are also equipped with sensors to detect edges and prevent them from falling down stairs or other drops.
It's important to note that while Roombas are generally good at avoiding obstacles, they may still occasionally get stuck in some situations. For example, they might have difficulty navigating complex or cluttered environments or dealing with certain types of obstacles (e.g., very low-clearance objects). Regular maintenance, keeping the area free of clutter, and using virtual walls can help optimize the Roomba's performance and prevent it from encountering too many obstacles.
