Trying to transform vectors between local and global frames
Additional question: how do we transform angular velocities? I am not sure, but i thing it is different from transforming vectors?

Unable to change texture of Gazebo oblect
Well, it can be a bug in Gazebo, but I wonder if anyone tried to alter textures dynamically?

Sensor fusion with Kalman filter: what should go as "command" in case we have a choice?
I think I closed it. Thanks.

As I found, the robot rund as expected on a straight path. And it fails when turning. The robot is 4 wheeled dif. drive, so it is all about slippage. Which explains a lot about my failures fith using Kalman filter. Question is, if I use control commands as Kalman input (i.e. speed/angular speed) will Kalman filter work if slippage is 50%? Or will I do better without this input, on sensors only?
