To make Gyro Sensor blocks appear in VEXcode V5, a 3-Wire Gyro Sensor must be configured in the Devices window.

Gyro Sensing#

Gyro Calibrate#

The Gyro Calibrate block is used to calibrate the Gyro/GPS/Inertial Sensor to reduce the amount of drift. It is recommended that this block is used at the start of the project.

  calibrate [GyroH v]

The Brain must remain still for calibration process to succeed, which takes approximately 2 seconds.

Choose which Gyro/GPS/Inertial Sensor to use.

In this example, the Brain’s Inertial Sensor will calibrate for 2 seconds before printing the current orientation of the Inertial Sensor.

  when started :: hat events
  calibrate [BrainInertial v]
  wait (2) seconds
  print ([BrainInertial v] orientation of [roll v]) on [Brain v] ◀ and set cursor to next row

Set Heading#

The Set Heading block is used to set the Gyro/GPS/Inertial sensor’s current heading position to a set value.

  set [GyroA v] heading to (0) degrees

The Set Heading block accepts a range of 0.0 to 359.99 degrees.

Choose which Gyro/GPS/Inertial Sensor to use.

In this example, the Brain’s Inertial sensor will print its starting heading, set its heading to 90 degrees, and then print the new heading.

  when started :: hat events
  print ([BrainInertial v] heading in degrees) on [Brain v] ◀ and set cursor to next row 
  set [BrainInertial v] heading to (90) degrees
  print ([BrainInertial v] heading in degrees) on [Brain v] ◀ and set cursor to next row

Set Rotation#

The Set Rotation block is used to set the Gyro/GPS/Inertial sensor’s current rotation position to a set value.

  set [Inertial1 v] rotation to (0) degrees

The Set Rotation block accepts any positive or negative decimal or integer number.

Choose which Gyro/GPS/Inertial Sensor to use.

In this example, the Brain’s Inertial sensor will print its starting rotation, set its rotation to -100 degrees, and then print the new rotation.

  when started :: hat events
  print ([BrainInertial v] rotation in degrees) on [Brain v] ◀ and set cursor to next row
  set [BrainInertial v] rotation to (-100) degrees
  print ([BrainInertial v] rotation in degrees) on [Brain v] ◀ and set cursor to next row

Angle of Heading#

The Angle of Heading block is used to report the 3-Wire Gyro Sensor or V5 Inertial Sensor’s current heading in degrees.

  ([BrainInertial v] heading in degrees)

The Angle of Heading block reports a range from 0.0 to 359.99 degrees.

Choose which Gyro/Inertial Sensor to use.

In this example, the Brain’s Inertial sensor will print its starting heading, set its heading to 90 degrees, and then print the new heading.

  when started :: hat events
  print ([BrainInertial v] heading in degrees) on [Brain v] ◀ and set cursor to next row
  set [BrainInertial v] rotation to (90) degrees
  print ([BrainInertial v] heading in degrees) on [Brain v] ◀ and set cursor to next row

Angle of Rotation#

The Angle of Rotation block is used to report the 3-Wire Gyro Sensor or V5 Inertial Sensor’s current rotation in degrees.

  ([BrainInertial v] rotation in degrees)

A clockwise direction is reported as a positive value, and a counterclockwise value is reported as a negative value.

Choose which Gyro/Inertial Sensor to use.
