I have used Openrave 0.8.2 on ubuntu 11.10 for a long time.
Recently my operating system was updated to Ubuntu 13.04, and I have installing openrave 0.9 from the testing PPA,
ppa:openrave/testing. But I find that some previous programs running on openrave 0.8.2 do not work, it seems that the
problem comes from the controller. I have also tested some examples of openrave 0.9, all of them have problems.
For examples, both testphysics_diffdrive.py and testphysics_controller.py can not work correctly. the robot can not be
controlled when the ODE is set.
