Hello I am having the same problem as you (except for all the namespace errors). I am trying to use the hinge2 joints in a model that a have created myself. But I get this error:
ODE INTERNAL ERROR 1: assertion "bNormalizationResult" failed in _dNormalize3() [../../../include/ode/odemath.h] Aborted I also get the same error when trying the simplecar .world example. The simplecar.model also uses hinge2 joints for its front wheels (so that you can turn). I have been trying to tweak hinge properties to make it work, but so far I have been unsuccessful. Hinge joints with one axis and ball joints have no problems. Could it be a Gazebo or ODE bug? Or do you have to tweak your hinge and wheel properties to make it work? I am running the latest Gazebo SVN with ode-0.11. /Peter Timothy Chan wrote: > Hi all, > > > I have Gazebo 0.9.0 running on ubunto 8.10.
