I'm trying to display the PR2 using ros3djs, using 'http://resources.robotwebtools.org/' as the path to resources.. However, I'm getting a bunch of errors from STLLoader.js in the form of:

GET http://resources.robotwebtools.org/pr2_description/meshes/base_v0/caster.stl 404 (Not Found)
Uncaught InvalidStateError: Failed to read the 'responseText' property from 'XMLHttpRequest': The value is only accessible if the object's 'responseType' is '' or 'text' (was 'arraybuffer').

(weirdly enough, the robot is still displayed)

Is there something wrong with my settings, or is the mesh hosting just down? Is there a way to find out?

It's a bug in pr2_common_actions:

https://github.com/PR2/pr2_common_act...

I'm trying to make the PR2 tuck its arms using this command:

  rosrun pr2_tuckarm tuck_arms.py -r t -l t

It works in Groovy, but not in Hydro. It doesn't give any error messages: the script launches, but nothing happens. I've also tried several other ways (like writing a script and calling the tuck arms action from code), nothing seems to work in Hydro. Is it something with my settings, or is it truly broken? If anyone could just check if it works for them in Hydro, that'd help a lot.

Thank you! I installed a new version of rviz (1.9.35) and that worked.

Thanks for the suggestion! The versions of ROS and boost are the same on the robot and the machine I'm running rviz from. I've also just discovered one more way to make rviz crash (see update).

I'm trying to launch the navigation stack for the pr2. Here's what I run:

1. rosrun map_server map_server basement_map.yaml
2. roslaunch pr2_navigation_global rviz_move_base.launch
3. (on the robot) roslaunch pr2_2dnav pr2_2dnav.launch

After I launch the 2dnav on the robot, the robot model appears in rviz. After about 10 seconds the red markers for obstacles appear and rviz crashes immediately. Usually it doesn't give an error message but sometimes there's also this message:

*** glibc detected *** /opt/ros/groovy/lib/rviz/rviz: free(): corrupted unsorted chunks: 0x000000000280e750 ***
======= Backtrace: =========
/lib/x86_64-linux-gnu/libc.so.6(+0x7eb96)[0x7fd273539b96]
/opt/ros/groovy
<....>

(there's a lot more text, here's the full error message: pastebin.com/ArwKkirr)

Sometimes the message looks similar, but starts with "corrupted double linked list" or "malloc error".

The same thing happens if I launch pr2_interactive_manipulation with navigation enabled (without navigation everything is fine).

I'm using Ubuntu 12.04, Nvidia driver 331 (I also tried it with 304 and with a generic driver, same thing happens).

Update: seems that the problem is caused by GridCells visualization. If I start with a fresh rviz ("rosrun rviz rviz") and add navigation-related topics one by one, rviz crashes after GridCells are added with a non-empty topic (for example, "/move_base_node/local_costmap/obstacles")

Update 2: Another way for rviz to crash turned out to be adding DepthCloud with a non-empty DepthMap topic (for example, "/head_mount_kinect/depth_registered/image").
