Hi all, We are working on a simulation model of an autonomous football table. We already build our model but we're struggling with the realism. We solved a lot of problems but to this one, we can't find an answer to. Here is a movie of the weird/unrealistic behavior: Movie: http://www.student.tue.nl/W/r.p.w.appeldoorn/gazebo_tablesoccer.avi Has someone perhaps experienced similar problems or perhaps does someone want to take a look at our code because we're probably making trivial mistakes. Code: http://www.student.tue.nl/W/r.p.w.appeldoorn/simulation.world Thanks in advance, Rein |

Hi Rein, Not sure if this will help, but have you tried reducing the friction coefficients of the wheels <mu1> and <mu2> to something less than 1? also, make sure that in the version of gazebo you are running, contact.surface mode has "dContactApprox1" in it. contact.surface.mode = dContactSoftERP | dContactSoftCFM | dContactApprox1 | dContactMu2; John On Thu, Jun 9, 2011 at 5:51 AM, Rein Appeldoorn <re...@gm...> wrote: > Code: http://www.student.tue.nl/W/r.p.w.appeldoorn/simulation.txt > <http://www.student.tue.nl/W/r.p.w.appeldoorn/simulation.world> > > On Thu, Jun 9, 2011 at 2:43 PM, Rein Appeldoorn <re...@gm...> wrote: > > > Hi all, > > > > We are working on a simulation model of an autonomous football table.

John, Thanks for your reply. What do you mean with the friction coefficients of the "wheels"? And how do I check my Gazebo-settings if they are right?

I checked my gazebo settings in /server/physics/ode/ODEPhysics.cc and they were as follows: contact.surface.mode = dContactSlip1 | dContactSlip2 | dContactSoftERP | dContactSoftCFM | dContactBounce | dContactMu2 | dContactApprox1; So this can't be the problem in my opinion. The parameters for the geometries of the table are as follows: <mu1>0.3</mu1> <mu2>0.3</mu2> <mass>1e5</mass> Any idea what we are doing wrong?

ah, sorry, I just went back to see the video again, and apparently I saw the wrong video earlier! Ok, the bouncing table problem is most likely a problem with max contacts specified. I've seen this when max contacts is set too low for the mesh involved. What version of gazebo are you running? can you attach or point me to ODEPhysics.cc? One way to fix this (not the best way) is, try putting a small box block under each corner of your "wall" mesh.

I'm using Gazebo version 0.9. This is because I had a problem with actuating the hinges via the generic-actarray in Gazebo version 0.10. Therefore, I'm using version 0.9 now. I'm not using a wall mesh; the wall consist of multiple box geometries. The movement of the table, what you saw in the movie, happens when rotating the rod. This is weird because the static part of the table (walls) have the following parameters: <mu1>0.3</mu1> <mu2>0.3</mu2> <mass>1e5</mass> I've added my ODEPhysics.cc and my .world-files: http://80.56.19.206/files/ODEPhysics.cc http://80.56.19.206/files/simulation_010.world (Gazebo 0.10) http://80.56.19.206/files/simulation_090.world (Gazebo 0.09) Thanks for responding!

Hi Rein, does the strange behavior change at all when you increase/decrease mass of the walls?

No, that's the weird fact, it doesn't change at all when I'm varying different parameters like mass, friction etc. What do you mean with "off the trunk"? I attached the piece of code for moving the rods: http://80.56.19.206/files/movingrodscode.txt More and more, I start to think that my Gazebo isn't set-up properly. First on 0.10, I got strange behavior when using the act-array interface. I couldn't event rotate a single hinge. Now, on 0.9, other thinks occur which aren't really explainable. Is there a way to check if your Gazebo is set up properly? Thanks again for helping me!

Hi all, I have a similar problem with the simulation of a modified pioneer on an inclined plane. If I make a pioneer with a mass of 21 kg to crash against a box of mass of 3000 kg, then the box starts rolling over the plane. My suggestion is that the moment of inertia of all the objects is set to a very low value (about 10e-10) and then even a small torque on an object cause it to roll. The same happens to you when the rod rolls, so that it applies a torque to the other objects (due to friction). Given the very low moment of inertia of teh table, it starts rolling. I even tried to set the inertia, but nothing changed. I post here because I think the two problems are related. I attach the files of my simulation. http://dl.dropbox.com/u/20433489/gazebo/pioneer3d.model http://dl.dropbox.com/u/20433489/gazebo/pioneer3d.world Any suggestions? thanks in advance Paolo 2011/6/16 Rein Appeldoorn <re...@gm...> > No, that's the weird fact, it doesn't change at all when I'm varying > different parameters like mass, friction etc. > > What do you mean with "off the trunk"? > > I attached the piece of code for moving the rods: > http://80.56.19.206/files/movingrodscode.txt > > More and more, I start to think that my Gazebo isn't set-up properly.
