Re: [Java-player-users] setPosition

[Matthias W. <mw...@gm...>]

Hi John, thanks your answer!

I didn't have a look at the player code, but now I think you are right. I
used ARIA before, which has a position interface, and thought it would be in
the p2os driver of player, too. I red in Pioneer Operations Manual, but the
position interface isn't on the robot, but in the software, so I have to
implement it myself and not just send a command.

Have a nice day!
