Hi all,
I have Gazebo 0.9.0 running on ubunto 8.10. When I try one of the
examples,
simplecar.world, I get an error. The Gazebo gui opens up and then
closes
after a moment, and this is what the terminal says:
gazebo simplecar.world
Gazebo multi-robot simulator, version 0.9.0

ODE INTERNAL ERROR 1: assertion "bNormalizationResult" failed in

Hello Timothy,
I had the same problem with file simplecar.world, which I traced to
file simplecar.model. It appears this is an error in file
simplecar.model itself.
The required namespaces are not included in file simplecar.model.
A patch for this specific problem is attached, and has been
submitted. A patch for the "ODE INTERNAL ERROR" was also submitted.
I realize this is months later, but perhaps this will help the next
person who has this problem.
Regards,
J. C. Allen
