I get from the device the angular velocity, quaternion and linear acceleration. I'm good with the rotation but not with translation. So.I'm trying to get it from linear acceleration but I can't exclude the gravity. Do you have some suggestions? 2016-05-27 11:46:36 -0500 commented question Imu acceleration to position exclude gravity effect Im using this device: https://store.3dr.com/products/3dr-pi... And Im working with ROS, so I get the linear accelerations but with the gravity include and I need to exclude it. 2016-05-27 11:33:06 -0500 received badge ● Popular Question (source) 2016-05-27 09:19:23 -0500 commented question Imu acceleration to position exclude gravity effect Many thanks for your suggestion. Maybe do you have or know another method to get the position? 2016-05-26 08:47:06 -0500 asked a question Imu acceleration to position exclude gravity effect Im working with a Pixhawk 3DR. And I need to get the position of the robot. I'm trying to calculate with the linear accelerations and a delta time, but I can't exclude the gravity effect. Im trying with this: x_posicion_var = (0.5*alx)*(delta_time*delta_time) y_posicion_var = (0.5*aly)*(delta_time*delta_time) z_posicion_var = (0.5*alz)*(delta_time*delta_time)  does some know how to resolve it? thanks 2016-05-26 08:40:24 -0500 commented answer IMU linear acceleration to position Hi. I have almost the same problem. And checking your inputs, you are taking a velocity value, where is it coming from? And how do you exclude the gravity effect ??? 2016-04-17 17:11:35 -0500 commented question Issues with RViz and Displaying IMU data Hi, I was trying your code, but I got an error.. IOError: [Errno 2] No such file or directory: 'input.bag' Do I have to write an script to make a tf?? or Do I have to write also an script to record such bag files? 2016-04-10 18:32:13 -0500 commented question Issues with RViz and Displaying IMU data Thank you very much. I will try it. Regards 2016-04-05 00:14:42 -0500 commented question Issues with RViz and Displaying IMU data I have the same situation. Did you solve the problem?
