Hello, I've just started with gazebo and got stuck at the begining: i'm trying to create simple box following the Model Creation Tutorial (gazebo-svn manual). This is the model I'm using: <model:physical name="box_model"> <xyz>0 1.5 0.5</xyz> <rpy>0.0 0.0 0.0</rpy> <canonicalBody>box1_body</canonicalBody> <static>false</static> <body:box name="box_body"> <xyz>0.0 0.0 0.0</xyz> <rpy>0.0 0.0 0.0</rpy> <geom:box name="box_geom"> <xyz>0.0 0.0 0.0</xyz> <rpy>0.0 0.0 0.0</rpy> <mesh>default</mesh> <size>1 1 1</size> <density>1.0</density> <material>Gazebo/BumpyMetal</material> </geom:box> </body:box> </model:physical> and nothing happens (no box is created). After looking through examples I've changed section describing box_geom to <geom:box name="box_geom"> <visual> <xyz>0.0 0.0 0.0</xyz> <rpy>0.0 0.0 0.0</rpy> <mesh>default</mesh> <size>1 1 1</size> <density>1.0</density> <material>Gazebo/BumpyMetal</material> </visual> </geom:box> </body:box> (i've added <visual> section - not in the manual - where can I read about it?) and I get this error: server/rendering/OgreVisual.cc:95 : Exception: Unable to create a mesh from default Can somebody explain me what am I doing wrong? Do I have to create my own mesh just to get a simple box? I'm using Ubuntu, latest svn verion of gazebo and ogre 1.4.5.

Hello, you can use the standard mesh unit_box, just insert <mesh>unit_box</mesh> somewhere in your visual section. Maybe there's something else, but I can't look it up currently. Hope it helps anyway.

But is it normal, that models are slightly collapsing into each other? For example if I put two boxes one on the top of another, the top one is collapsing into the bottom one. Is it possible to set the "hardness" of the surface? It's frustrating when the boxes with greater mass (100 kg) are falling slightly into the ground plane...

Hi, Try increasing the kp of the geoms, e.g. <kp>100000</kp> You could also try decreasing the cfm of the whole simulation, that helped when I had a similar problem with joints.

Hello, There are also problems when some objects in the environment have disproportionately large masses compared to other objects. If you need an object to be immovable, then make it static. -nate 2008/4/17 David Olsen <raz...@gm...>: > Hi, > > Try increasing the kp of the geoms, e.g. > > <kp>100000</kp> > > You could also try decreasing the cfm of the whole simulation, that > helped when I had a similar problem with joints. > > Thanks, > David > > > > On 18/04/2008, Kamil Muszyński <mus...@gm...> wrote: > > > > > > Benjamin Kloster wrote: > > > > > > Hello, > > > you can use the standard mesh unit_box, just insert > > > <mesh>unit_box</mesh> > > > somewhere in your visual section.
