Re: reset position of the controller using supervisor_field_set

Sorry, me English es very poor:

I want reset the position of the my robot, I wan't receiver
information in my robot. I only want put my robot in a place when need
it. I want the code for put my robot in a coordenades when the normal
controller need it.

I want apply Swarm Intelligence for learning to move for the laberint
and I need use fitness funtion that each execute reset the position
the robot for can evaluate the fitness of the movement. I don't
understand why I have to use the supervisor.
