When Boundary Obstacle Avoidance is ON Yarbo will intelligently bypass obstacles along the boundary using both visual and ultrasonic sensors—based on the Obstacle Avoidance Mode you select (Sensitive / Moderate / Gentle Contact / Custom).
When It's OFF Yarbo will turn off visual and ultrasonic obstacle detection near boundaries, but still rely on its physical bumper bar for basic collision response.
This gives you more control over how Yarbo reacts to complex edges like fences, trees, or garden decor. Test it out and adjust for the perfect balance of caution and confidence!
