We are having trouble with coding our Inertial Sensor. When it is supposed to stop it still proceeds to keep turning in a circle

If anyone can help it would be much appreciated

As with any programming question, can you post your code?

LFmotor.spin(forward);

LBmotor.spin(forward);

RFmotor.spin(forward);

RBmotor.spin(forward);

waitUntil((Inertial.rotation(degrees) >= 45.0));

LFmotor.stop();

LBmotor.stop();

RFmotor.stop();

RBmotor.stop();

wait(10, msec);

After the RBmotor.spin(forward); command, place a Brain.Screen.print(intertial.rotation(degrees); Your code should look like this:

LFmotor.spin(forward);
LBmotor.spin(forward);
RFmotor.spin(forward);
RBmotor.spin(forward);
Brain.Screen.print(Intertial.rotation(degrees));
waitUntil(Intertial.rotation(degrees) >= 45.0);
LFmotor.stop();
LBmotor.stop();
RFmotor.stop();
RBmotor.stop();
wait(10, msec);

The value on the screen would be your rotation in degrees. I have a feeling that it is reporting negative values. Which way is the robot rotating?

ok thanks I’ll try this
it is rotating counter clockwise btw

If its rotating counterclockwise you could just set the wait until function to be less than or equal to -45.0 degrees, like this:

waitUntil(Intertial.rotation(degrees) <= 45.0);
