Well, we're not entirely out of the gazebo realm. that's a resource related to the <transmission> tags in the urdf

Nope. The model is fine now that I've fixed the inertia tensor.

@chapulina, looks like I found the issue. There was some error when the model was created in solidworks and there wasn't

@chapulina, The robot looks fine before the simulation is started. I don't really see anything in verbose mode either. G

2016-09-08 12:11:36 -0500 asked a question Help understanding what's going on with the forces on Atlas' foot.

I'm recording the forces on Atlas' foot while walking normally. The forces in the beginning behave as expectedimage description.

However there's some crazy oscillation towards the end when both the feet are on the ground. I'd like to understand why that is happening.

Thanks

2016-08-11 15:21:16 -0500 asked a question Can't seem to add plugins to DRCsim models

I'm trying to add a bumper plugin to the drcsim atlas model so I tracked down the atlas.urdf file that is run by roslaunch drcsim_gazebo atlas.launchand added the following code for the r_foot link

<gazebo> <plugin name="${name}_gazebo_ros_bumper_controller" filename="libgazebo_ros_bumper.so"> <alwaysOn>true</alwaysOn> <updateRate>${update_rate}</updateRate> <bumperTopicName>${name}_bumper</bumperTopicName> <frameName>world</frameName> </plugin> <gazebo>

By my understanding this is supposed to create a topic called atlas_bumper but I don't see anything of that sort when I run rostopic list. I'm new to this, what am I doing wrong?

Thanks

2016-08-11 14:30:16 -0500 asked a question Where is the Atlas urdf file used by drcsim stored?

I'm trying to add a bumper plugin to the atlas robot and so I'd like to find the URDF file. I run roslaunch drcsim_gazebo atlas.launch to launch the simulation. So far I've managed to find the launch file but I don't know where to go from there. Thanks.

2016-08-01 11:13:42 -0500 asked a question How to check which functions are being called?

I'm trying to take a simple event in which the Atlas steps on the ground plane. I want to see which functions ODE calls and the functions ODE uses to determine the constraint forces. I'd like to see this happen while the simulation is running. Is there a way I could do that? I'd like to know what constraint equations and constraint forces ODE is using for that particular case. Thanks.

2016-07-05 10:12:32 -0500 commented answer How does ODE determine contact points in Gazebo?

Thanks for that answer. The Atlas feet are indeed approximated as boxes however the STL file is already made up of triangles I don't know how I would refine it further and whether that refinement would stop gazebo from approximating it as a box.

2016-06-22 14:47:13 -0500 asked a question How does ODE determine contact points in Gazebo?

I was looking at the contact points for the Atlas in the DRCsim package. Each foot has 4 contact points at each vertex of the rectangle. I'd like to know how these points are determined. I've tried looking at the ODE code, but C++ isn't my strong suit so I had some difficulty figuring out what was going on. What I understand is that ODE compares the geometries one by one however it's not possible to compare all points so it only compare a select few points. What I'm trying to understand is what basis are those particular points selected? Why does the Atlas have the 4 contacts set up the way they are, and not some additional points on the heel? Can I add them myself?

Thanks.
