1. No. Stage doesn't model the kind of physical interactions that are
important in box-pushing. You might try Gazebo, which uses a more
plausible physics engine, but I don't know how realistic object
interactions in Gazebo are.
2. That's odd. If you still have the source for Stage where you compiled
it, look in the file 'config.h', and find the #define COLOR_DATABASE.
Make sure it points to your rgb.txt file. If it doesn't, you can
re-configure Stage, passing --with-color=<path>, where <path> is the
absolute path to your colors file. Then re-make and try again.
