Gyro Programming

[Straberrie]

Hi, how are you?

I am trying to get gyros to work and I never programmed the sensor before, so I made use of the FIRST programming guide to implement gyros in the autonomous period.

Gyro *gyro;
gyro = new Gyro (1);

gyro->Reset();
gyro->SetSensitivity(.005);

float angle = gyro->GetAngle();

myRobot->Drive(-1.0, -angle / 30);
Wait(4.0);

According to the guide, the above should have corrected the robot's path and set it to match the heading of the original angle. Since the original angle was 0, it should have went straight.

However, when we tested it on the robot, it immediately made a sharp turn.

In order to see what is happening with the angle values, I created an if statement

float angle = gyro->GetAngle();

if (angle<0.5)
{
myRobot->Drive(1.0, 0.0);
Wait(0.0);
}
else
{
myRobot->Drive(0.0, 0.0);
Wait(0.0);
}

And it stood, I switched the statements around, and the robot didnt move either. So, I am wondering what I did wrong and how I can make the robot follow a straight path.

Any help would be appreciated,

Thank you!
