I am currently working on a project where I am using some pretty complex equations to move my robots. However, I can see (even when im not applying any velocity, nothing) that my robot pose on rot.z is changing by itself (little values, but I want it to be = 0 if there is no reason not to be).

I don't understand why, my robot is a Pioneer3AT, I used the official robot on wich I added an hokuyo laser at it's top. Where does this problem come from ? I think it's from a setting in the .world file but I don't know what it could be.

Here is my file : (sorry it's very messy)

thank you in advance guys, it's for my internship it's pretty important.

Could be the contact parameters. In the GUI would you mind turning on contact visualization, transparency, and then taking a video?

Actual answer this time:

Gazebo has a long-standing bug till latest 7 ( This causes pioneer to strafe with constant velocity. Remove fdir1 param from the xacros and do make. It should fix the ussue.

Can't try if it is okay in gazebo 8, sorry
