Measure speed and distance using ADIS16495

HI Raja,

I apologize for the slow reply.  In principle, this is not a difficult measurement, as you can integrate the accelerometer data to get velocity, and integrate velocity to get distance. The difficulty is that a double-integration will lead to the rapid accumulation of error that go up with the cube of time. On the other hand, using the wheels of the robot for odometry will lessen the error significantly.

very thanks for your.

actually i have both odo meter and IMU. In pipe odo can slip many times so i want to measure speed and distance using IMU.

Are you ever work on ADIS16495?

actually it has delta velocity register, i can get data from it but i don't know how use it to measure speed and distance in my C code programming language.

and what is the sample rate of delta velocity?

Please reply i need help....
