Player/Stage : Error in running 3 roomba robots

General Discussion

Hi,
I am working on a player/stage project which currently has 3 (Later it will be extended to 6) iRobots -Roomba.
As suggested in Jenny Owen’s Tutorial on player/stage http://www-users.cs.york.ac.uk/~jowe...ial-manual.pdf , I was giving different port numbers to each one of the robots.

Here is my .cfg file :

driver
(
name “stage”
provides [ “simulation:0”]
plugin “stageplugin”
worldfile “pacman.world”
)

driver
(
name “stage”
provides [ “6665:position2d:0” ]
model “pacman”
)

driver
(
name “stage”
provides [“6666:position2d:0” ]
model “ghost1”
)

driver
(
name “stage”
provides [“6667:position2d:0” ]
model “ghost1”
)

But, I am getting this error when I am running ./ghost1 and ./ghost2 :

playerc error : got NACK from request

The simulator is not able to run the other two robots, I guess.

Kindly help me in this regard.

I have no experience with the player/stage project but just noticed that you have two models named the same:

driver ( name "stage" provides ["6666:position2d:0" ] [b]model "ghost1"[/b] )

driver
(
name “stage”
provides [“6667:position2d:0” ]
model “ghost1”
)
