How does the IQ gyro sensor work?
Gyro's make the turn very accurate. The encoders in the Motor Modules help by accurately moving a specific number of turns. The VEX IQ Gyro Sensor uses a Texas Instruments MSP430 microcontroller running at 16 MHz to process requests and calculate angles.
What is the VEX yaw rate gyroscope?
This sensor is not like the other VEX sensors, which are all color-coordinated in red plastic, and friendly-looking. Think of this as a bare component that VEX commandeered and is making use of. The official name for this sensor is the VEX Yaw Rate Gyroscope Sensor.
How do I connect my sensor to my gyroscope?
Connect this sensor to one of your analog ports with the usual 3-wire extension cable; the black wire of the cable gets plugged into the pin on the gyro that has a small “B” printed next to it. If you plug this in backward, nothing will happen—no data will be returned from the sensor.
What does a Gyro Sensor do VEX IQ?
The Gyro Sensor can be used to keep the robot driving straight and also to make accurate turns. If you want a robot to drive to a location then turn around and return to the same spot, you will need to move straight for an accurate distance, turn exactly 180 degrees, then drive back straight for the same distance.

Why do you have to calibrate the Gyro Sensor?
Calibration is necessary for the gyro sensor because if the robot isn't stationary when turned on or when the gyro is plugged in, the gyro may not understand what it means to be still. This can make the sensor value drift.
How does Lego Gyro Sensor work?
The digital EV3 Gyro Sensor measures the robot's rotational motion and changes in its orientation. Students can measure angles, create balancing robots, and explore the technology that powers a variety of real-world tools such as Segway®, navigation systems, and game controllers.

Why does my gyro drift?
The gyro is sensitive to vibration, a lot. So lots of vibration will cause the gyro to start “drifting” in its returned value; a lot of vibration will cause a lot of drift. And so will a little vibration over a long period of time driving the robot.
What happens if a sensor turns 60 degrees?
So if it turns 60 degrees, the sensor will read 600. Sensor values can be negative! If you turn in one direction from your starting “north pole,” the sensor will give you a positive value; if you turn back to your starting point and keep going, the readings will be negative.
How many degrees per second does a sensor rotate?
According to the easyC help files, the sensor has a maximum rate of rotation between 80 and 300 degrees per second, so if you’re spinning like a Tasmanian devil, it will probably give you … misleading information.
Can you write about integrated motor encoders?
Yes, yes, I keep promising to write about Integrated Motor Encoders. However, one of the other coaches on the VEX World Coaches Association Facebook group and I got started chatting about the VEX gyro sensor, and it had me collate all of the information I have about the gyro in one place. So I thought I’d dump it all here now.
What is a vex IQ?
The VEX IQ Gyro Sensor uses a Texas Instruments MSP430 microcontroller running at 16 MHz to process requests and calculate angles. The MSP430 communicates with the latest MEMS Gyroscope across a very high speed 10 MHz SPI bus. The MEMS gyro measures rotation rate with 16 bit resolution. The data is filtered and tracked over time to determine the angle. All this technology works together to make a smart gyroscope that is simple, flexible, and powerful.
How to demonstrate a gyro?
The quickest way to demonstrate a Gyro is to plug one into a VEX IQ robot. The programs built-in to the Robot Brain will automatically detect the gyro and start using it. The Driver Program will remember the robot's direction when it is turned on. Drive your robot around and when you stop, the Gyro will help it turn back to it's original direction.
How to use a gyro?
Use. The best use for a gyro is to make accurate turns. If you want a robot to drive to a location then turn around and return to the same spot, you will need to move an accurate distance, turn exactly 180 degrees, then drive back the same distance. Gyro's make the turn very accurate.
What is a gyroscope?
Gyroscopes measure how fast it is turning. Also called a Gyro, they are commonly used for navigation. By tracking how fast and which way a robot is turning, they can determine the direction your robot is facing.
How The Gyro Sensor Works
- The Gyro Sensor only detects movements that are clockwise or counterclockwise on the axis indicated on the top of the sensor. So if the gyro is mounted horizontally in the center of the robot, it does not detect if the robot is tilted downward or upward on a slope as long as the gyro hasn’t …
Common Uses of The Gyro Sensor
- Gyro sensors are integrated into many pieces of technology where knowing the orientation of a device or stabilizing an object are important. Some common uses in daily life include: 1. Gyro sensors are integrated into small motorized vehicles that allow the person to control speed by leaning forward and backward, while also keeping the vehicle stable. 2. Gyro Sensors are used t…
Gyro Sensors on A Competition Robot
- The Gyro Sensor can be important for programming a robot for competitions. The gyro is especially important when programming for the autonomous period when the robot has to perform tasks without human input. The Gyro Sensor can make a competition robot better in the following ways: 1. The Gyro Sensor can detect which direction and how far the robot has turned …
The Component
Installation
- First, the top of the gyro is the side with the pins sticking out of it, and the 2 big holes are for screwing it onto your robot somewhere (more on that below). Connect this sensor to one of your analog ports with the usual 3-wire extension cable; the black wire of the cable gets plugged into the pin on the gyro that has a small “B” printed next to...
Mounting / Vibration
- The gyro is sensitive to vibration, a lot. So lots of vibration will cause the gyro to start “drifting” in its returned value; a lot of vibration will cause a lot of drift. And so will a little vibration over a longperiod of time driving the robot. The super-awesome jpearman from the VEX forum did a series of tests on the sensor, mounting it in different places and noting the effects. First it was …
What It Measures
- The sensor outputs the degrees the robot has turned away from the “north pole” of where it was facing when you turned it on and started your program running. The value the sensor returns is in tenths of a degree. So if it turns 60 degrees, the sensor will read 600. Sensor values can be negative!If you turn in one direction from your starting “north pole,” the sensor will give you a pos…
Orienting Itself: Gimme A Sec!
- The robot needs to sit perfectly still for several seconds when the gyro is started in order for it to calibrate itself to the big wide world. In competition programs, you do this gyro-initializing step in the Initialize (easyC) or pre-autonomous (RobotC) portion of the program, so it does this “I need to sit still so don’t bother me” part when the team is standing around doing nothing anyway.
Scaling
- Every device is a little different, and none of them will return 600 exactly when you turn it 60 degrees. So you must figure out the scaling factor for your component before you can really use this thing. The good news is that the scaling factor is linear, so you just have to figure out one number; it’s not some crazy logarithmic or geometric thing you have to figure out. 1. In all of you…
Limitations
- According to the easyC help files, the sensor has a maximum rate of rotation between 80 and 300 degrees per second, so if you’re spinning like a Tasmanian devil, it will probably give you … misleading information.
That’S Lovely, Now What Do I Do with this?
- As I mentioned at the start, now you treat your incoming information the same way you would treat, say, potentiometer data you’re using to lift up an arm. If I wanted to turn my robot 90 degrees, I could use a while loop (in a very simple example): desiredValue = round(90 * 10 * scalingFactor); actualValue = get(sensorValue); while (actualValue <= desiredValue) { set chassi…
