It is possible to use a copy of the world to evaluate the trajectory of an object (like a ball a robot want to catch)
and then sincronize the copy with the real world?
what i need is a a way to clone the dynamic world and make several step with all or some of the object active (i would prefer that the robot can not simulate all the object in the world but only some, i.e. those that it has seen) and then to move the state of the cloned world back to that of the true world.
Any suggestion is wellcome.. consider that I'm a newbie
