n the "Navigation through Traffic" module, learners use the ultrasonic sensor to simulate smart traffic systems by navigating a classroom maze. The obstacle avoidance logic dictates that the FOSSBot repeats its forward movement until the distance to an object is less than 5 cm. When setting up your physical mazes using chairs or boxes, how tight do you make the turns for the 13-16 year old groups? Do your students usually struggle with programming the exact sequence of stopping, showing a red light, and rotating 90 degrees?
