2012-09-18 12:06:10 -0500 asked a question How to store "stretching" forces from the PR2 using Gazebo?

Hi,

I am still fairly new using Gazebo, and this time I am trying to simulate the PR2 robot interacting with cloth. I need to obtain, and specially store, the forces the PR2 robot is applying when manipulating the cloth meshes. For example, after the PR2 grasps a rectangular piece of cloth from 2 adjacent edges, I need to store the forces required to stretch the cloth in all possible directions. How can I do this?

Thanks for any kind of help in advance.

Best,

Stalin

2012-08-28 19:57:20 -0500 asked a question How to import Collada (.dae) files into Gazebo (ROS/Fuerte)?

Hi,

I am trying to import a COLLADA (.dae) file into Gazebo (from ROS/Fuerte) in order to run some simulations with the PR2. I created the file using Blender, and it basically has an environment (with some tables and walls) and cloth simulations as well. Unfortunately, I haven't been able to simulate this "world" in Gazebo.

I tried following this tutorial, but the "cob" part seems to be for a different version of Gazebo (not Fuerte); besides, step 5 leads to an infinite loop! I also tried changing the code from the wg_collada.world and wg_collada_world.launch as is recommended here but no luck. Then, I tried this one too, but the source paths are not specified for Fuerte yet, so no luck there either. Finally, this one didn’t work, because of the same reason as the later.

I would really appreciate it if anybody can help me figure this out. Thanks,

Stalin
