Basic Java – Robotics Programming

The purpose of this section is to provide a basic introduction to the Java language. This is not to be considered an in depth study, what we are going to try and do is introduce the basics that you will need to know in order to work through the various robot programming tutorials. So let’s get started by creating our first program using Eclipse.

If you do not currently have Eclipse installed you can check out the Installing Tools section for instructions on how to set up your computer.

  public void execute() 
  {
    Logger.Log("ArcadeDriveCommand", -1, "execute()");
    
    double	y	= m_joystick.getY();
    double	x	= m_joystick.getX();
    
    if (x < 0)
    {
      x = -x * x;
    }
    else
    {
      x = x * x;
    }
    
    if (y < 0)
    {
      y = -y * y;
    }
    else
    {
      y = y * y;
    }
    
    m_subsystem.setPower(y + x, y - x);
  }

public void execute()

{

Logger.Log("ArcadeDriveCommand", -1, "execute()");

double y = m_joystick.getY();

double x = m_joystick.getX();

if (x < 0)

{

x = -x * x;

}

else

{

x = x * x;

}

if (y < 0)

{

y = -y * y;

}

else

{

y = y * y;

}

m_subsystem.setPower(y + x, y - x);

}
