2016-12-12 01:51:41 -0600 asked a question tracked robot Gazebo-ROs

hello, I'm trying to create a simulator in gazebo under ROS, for a robot base. This robot base has tracked wheels. I would like to ask you how to implement them in ros and Gazebo, in particular:

  • is there any kind of specific transmission ?
  • do I have to build the urdf xacro in a particular way ?
  • is there any kind of example (I didn't find it from my own)?

thanks in advance

Yes, exactly! I tried to re-install again ROS, but the problem persists. shape_world.launch is the only one who doesn't return me the error.

Hi, thanks for the comment! I'm able to run 'gzclient', but when I run 'gzserver' I have the same error terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc but if I run some launch file for spawn robot into gazebo, it works! I don't know why the I run only gazebo or the empty_world.launch, it doesn't work BTW, I tried to install the last versione gazebo7, but returns me the same problem

Hello there, I'm an italian student who is starting to use Gazebo and ROS Hydro to implement a simulation with youBot KUKA for my Master Thesis. In order to make a good work, I would ask you what are the best computer configuration required to obtain the best simulation. Thanks for all
