I’m trying to simulate a roomba with some extra stuff in Stage but I have some problems with the position 2d proxy. When I want to get the pose of the simulated robot, I always get a (0, 0, 0), no matter where the robot is and no matter I use GetXPos(), GetYPos() or GetPose(). I tried to use my client in the examples that are already written in the Stage distribution, but I also get the same result. I even did a SetOdometry(x,y,yaw) just before calling to GetPose(). The result is once more (0,0,0). Could anybody help me? Is this a common problem? Thanks in advance.
