Hello,

I updated gazebo today (from apt (ubuntu 12.04)) and when i load one of my robots to gazebo all of the robot parts appear in random places.

URDF for my robot is located in : https://github.com/RCPRG-ros-pkg/lwr_robot/tree/electric/lwr_defs

After updating to svn trunk it works much better. But that not solve all of my problems, the second robot link appear translated from its base. It looks like a problem with chaining of fixed links. When i remove the world link and world to world_link joint the offset disappear. image description

update

Ok, there was another issue, thanks konradb3 for the patch! The new release simulator_gazebo 1.6.16 deb is out.

Thanks for posting the model, I was able to test it and found a transform bug when I tried to tweak the urdf2gazebo parser. It's fixed in trunk. I'll make a release (simulator_gazebo 1.6.14) this weekend.

I checked the svn trunk and it works much better but some problems still remains.

Comment by hsu on 2012-08-24:
great. can you list out the problems or ticket them on trac (https://bitbucket.org/osrf/gazebo/issues?status=new&status=open)? thanks!

i'm seeing a similar problem with the Robonaut2 simulator since the update as well.

Problem also exists with the youBot URDF from https://github.com/youbot/youbot-ros-pkg

Comment by bsatzinger on 2012-08-27:
I'm seeing similar problems as well. Is there documentation somewhere on the best way to checkout simulator_gazebo from svn trunk and replace the existing version I got from apt-get without goofing everything up?

Comment by shart115 on 2012-08-28:
any updates on this fix? It is somewhat unclear whether the trunk fixes this issue (and it doesnt look like 1.6.14 has been released yet...

Comment by hsu on 2012-08-28:
just released 1.6.14 yesterday, deb should be out in a day or two. Is the second picture in your original question correct? That's what I see as well. Is there suppose to be a gap between calib_lwr_arm_base_link and lwr_arm_1_link as shown? Also, you mentioned that something else is broken?

Comment by hsu on 2012-08-28:
If possible, can you post a picture of what the model should look like? thanks.

can someone confirm that simulator_gazebo 1.6.14 fixes the issue?
