I need help making a UML diagram for a maze robot using Java. The robot is a Finch robot that has IR sensors and a buzzer. It's supposed to traverse through a maze from start to finish while avoiding obstacles. It sounds the buzzer at the finish line.

2. I need help with a UML class diagram that explicitly documents the design of the application.
4. I need help with a UML class diagram that documents the relationships between user-developed classes.
