Re: reset position of the controller using supervisor_field_set

I just want to reset the position of my robot, but I don't want to
receive the real position in it.
Instead of that, I only want to use the normal controls of the robot
to place my robot in a determinate coordinate.

I am implementing "Swarm Intelligence" algorithm to learn how to move
within the labyrinth and it's necessary that
the "fitness" function leaves the position of the robot in the same
place in which it was before its execution.
That is the reason why I need resetting the position of the robot in
the robot controller and .

What I don't understand is why I must use the supervisor and if I only
want to move my robot with its
controller, I would not need sending anything from the emitter. In
addition to this I want to reset the position when
I need it not when the supervisor would think it is the time for that.
