Package edu.wpi.first.wpilibj

Class RobotBase

java.lang.Object
edu.wpi.first.wpilibj.RobotBase
All Implemented Interfaces:
AutoCloseable
Direct Known Subclasses:
IterativeRobotBase
public abstract class RobotBase
extends Object
implements AutoCloseable
Implement a Robot Program framework. The RobotBase class is intended to be subclassed to create a robot program. The user must implement startCompetition(), which will be called once and is not expected to exit. The user must also implement endCompetition(), which signals to the code in startCompetition() that it should exit.

It is not recommended to subclass this class directly - instead subclass IterativeRobotBase or TimedRobot.

  • Constructor Details

    • RobotBase

      protected RobotBase()
      Constructor for a generic robot program. User code can be placed in the constructor that runs before the Autonomous or Operator Control period starts. The constructor will run to completion before Autonomous is entered.

      This must be used to ensure that the communications code starts. In the future it would be nice to put this code into its own task that loads on boot so ensure that it runs.

  • Method Details

    • getMainThreadId

      public static long getMainThreadId()

    • close

      public void close()
      Specified by:
      close in interface AutoCloseable

    • getRuntimeType

      public static RuntimeType getRuntimeType()

    • isSimulation

      public static boolean isSimulation()
      Get if the robot is a simulation.
      Returns:
      If the robot is running in simulation.

    • isReal

      public static boolean isReal()
