Xittx
i have been trying alot making a global map from the local maps genrated at robot ends. i have been able to send laser data to and position2d data between the robots but canot be able to utilize them to build a global map.

void PositionProxy::FillData (   player_msghdr_t   hdr,
                const char *   buffer
        )  

could this function be helpful for this. plzz help me.

There are a couple of mapping algorithms that ship with Player: mricp
and mbicp for example.  You may be able to use either of those drivers
to make your map.  There are a lot of other algorithms at openslam.org
that you could probably modify to use with Player.  The FillData
function is not related to mapping.

thankyou for ur answer Rich. mricp only require only one position2d data . my concern is to build a global map that requires position data of multiple robots along with their laser data. what would you recommend me , should i modify the existing mricp or try openslam ? . any hint would be appreciated.
thankyou
