Questions tagged [gyro]

A gyroscope measures angular orientation and is calibrated relative to it's starting orientation. A true Gyro is a relatively rare and expensive piece of equipment, Most MEMs based "gyros" are actually rate gyros which have an output proportional to the rate of change of angular orientation.

What are the differences between a gyroscope, accelerometer and magnetometer?

What is the difference between a 3-axis gyroscope, 3-axis accelerometer and 3-axis magnetometer? How do these sensors work? Why are all 3 used in some devices like smartphones, tablets, quadcopters etc.?

How to determine position from gyroscope and accelerometer input?

I have a 3-axis accelerometer and a 2-axis gyroscope. I intend to measure something that only moves in the X and Z axis. I've heard of using Kalman filters to smooth out the acceleration vectors, but I can't find a good tutorial for a complete…

How Precise can I get with Accelerometer and Gyroscope

I want to build a little project to track an objects position in space. For this I intend to use an accelerometer and a gyroscope. The problem is I want this tracking to be very precise, and I haven't been able to figure out how precise you can…

Limits of dead reckoning using MEMS sensors

I'm trying to track body parts relative to a person's torso. I see quite a few questions about using MEMS accelerometers and gyros for dead reckoning, and they confirm my suspicions that various factors greatly limit their usefulness for these sorts…

AHRS algorithm under continuous linear accelerations

I have tried several algorithms to get pitch, roll and yaw under continuous linear accelerations and vibrations (smaller than 0.4g, frequency lower than 10HZ). None of them give good results because the readings either drift or are affected too much…

Dead reckoning with accelerometer & gyro. Possible?

I have a 3 axis accelerometer and a 3 axis gyroscope. I've been tasked with developing a dead reckoning system using this hardware. Essentially what's needed is for me to develop some code to track the position in 3d space of the board in real time.…

How to read a gyro/accelerometer

I recently purchased this MPU6050 GY-521 breakout board. I tried it with my Arduino Mega using this Arduino sketch provided by official arduino.cc. (MPU-6050 Datasheet, InvenSence (producer) Page) Man, it gives this weird output!!! InvenSense…

Does a gyro need to be placed at the center of rotation?

When using a gyro chip to measure angular velocity, does it matter whether it is located at the center of rotation? I've seen it mentioned online without much explanation that it should be placed at the center, but in my introductory physics courses…

accelerometer/gyro combo question

I have a system arm that free-ranges within a certain area. The arm swings, translates and rotates about a vertical axis which sits atop a mobile base. The mobile base can move any direction in the X-Y plane. It's movements are strictly…

L3G4200D random spikes

I've searched this forum a bit in regards to the L3G4200D gyroscope, and haven't seen this problem mentioned, but I have seen others talk about it on other forums. I am seeing a strange large value in my output when the gyroscope is stationary.…

Do MEMS or optical gyroscope record Earth's rotational and revolutional angular velocities?

I am using a 3 axis gyroscope (Android device) to record angular velocities using a sensor data logger application. When the device is placed stationary, the gyroscope recorded the following values: X: 0.003 Y:0.00042 Z:0.0045 At an instantaneous…

Is The Magnitude of Gyro XYZ Meaningful?

Say I have a gyro that outputs degrees/second, and I take the euclidean magnitude of the x,y, and z rotations: $$ \text{magnitude} = \sqrt{x^2 + y^2 + z^2} $$ Is this actually useful? Is magnitude now "total degrees/second"? Or does the weirdness…

Arduino + gyro/accelerometer == flight controller ...?

Can I use the combination of an Arduino Mega + MPU-6050 gyro/accelerator module instead of a flight controller? Is there something else needed? It is said that the gyro/acceleration can be used to maintain the balance of the flying vehicle. How is…

Msp430g2553 i2c communication library with itg3200 gyroscope

I've been creating an I2C library for communicating with ITG3200 gyroscope for MSP430g2553 experimental launchpad. I still have slight problems with sequential reading and the signed values but I'm nearly complete. Can you help out the last problems…
