[Start with Px4: Ground Vehicle Robot]

Hi, I am newbie to PX4. I wish to start using PX4 for my application which includes ground robot (kind of crawler). Is PX4 support this kind of application or only specific to Drones? Please suggest me where should I look more to know about PX4 uses on Ground Vehicle Robot, some basic examples and requirements.
Thanks, Best Regards.
