This Landroid tool handles different obstacles differently. When it encounters small objects like toys, sticks or dog poop, it runs over them. But with bigger objects like a tree branch, it will either bump into the branch and turn around or sense the branch and go around it. To detect obstacles, the Landroid uses an Anti-Collision System (ASC), but this comes as an add-on and is not integrated into the robot. The ASC helps detect obstacles and navigate better via ultrasonic detection.
