2012-12-21 10:56:49 -0500	answered a question	Effect of Stiffness and Mass on Gazebo Simulation stability You said: My question is why would stability be affected if I only add an additional variable of type hydmotor? I believe you answered your own question in your first sentence. You added a new model of your hydraulics which was very stiff and consequently you needed to drop your integration plant dt. This sort of problem is endemic to all numerical simulations really. If running your simulation slower isn't an option, I'd investigate if there's any way you can change your hydraulic model to make it less stiff.

2012-12-11 09:00:23 -0500	answered a question	DRCSIM: gazebo crashes when model launced as "pinned" The DRCRobotPlugin unpins the simulation automatically after 10s. There was one bug fixed already regarding the mode setting: code fix Of course you'd have to build from source or wait for the next release to get this fix.
2012-11-15 09:45:58 -0500	asked a question	Gazebo Physics Solver Type: quick vs. world Can anyone expand upon the quantitative/qualitative differences between running with the "quick" or "world" solver settings in Gazebo? My understand is the quick solver is faster than world, but at what expense? Is one or the other quantitatively more accurate? Is the world solver currently supported? In the latest DRCsim release changing the solver type to "world" makes the sim fail. Many thanks
