Choose the section for the coding language or resource you are using.
Use the sidebar or search bar to find a device, category, block, command, method, or class.
Read the description to understand what the command does and when it is useful.
Check the parameters to see what inputs are needed and what options are available.
Review the example to see one way the command can be used in a project.

For text-based examples in Python or C++, select the Copy button to copy the example, then paste it into your coding environment.

Start with the device or category you are working with, such as Drivetrain, Brain, Controller, or Sensors.
Read the description before copying an example so you understand what the command is meant to do.
Check parameter tables carefully. Small changes to inputs can change how the robot behaves.
Use examples as a starting point, then change values, directions, ports, or names to match your own project.
