2014-11-10 22:17:25 -0600 asked a question DART support for Mac OS X?

I'm running Gazebo on Mac OS X and I'd like to use the Dart physics engine.

When installing Gazebo, I followed the instructions to compile from source (http://gazebosim.org/tutorials?tut=install). Under "Compiling from Source (Mac OS X)" --> "Optional dependencies", it says to run "brew install gazebo4 --with-bullet --with-simbody", but makes no mention of how to install Dart.

Is this because there isn't Dart support for Mac OS X? Or is there some other command I can run to enable it?

Thanks very much!

2014-10-31 01:20:31 -0600 asked a question Simple robot bounces when placed in world

I have a simple structure that is a vertical pole connected to a horizontal pole at its top (forming an upside-down-L shape). A box hangs from the end of the horizontal pole. Since the structure isn't balanced, I added a joint between the body and the world to keep it from falling down. It doesn't fall down anymore, but now when I place it in the world it keeps bouncing up and down a small amount. Please let me know if you have any advice! Here's my model.sdf code:

<link name='body'>
