I tried to send this out a few weeks ago and it disappeared. Here's trying again!
Susan ---------- Forwarded message ---------- From: Susan Fox <f...@macalester.edu> Date: Tue, Jun 2, 2009 at 11:03 AM Subject: Pyrobot, Player/Stage, and Ubuntu 8.0... To: pyro-users@pyrorobotics.org Hi, there, I have installed Player/Stage 2.0.3 on my Ubuntu system, running Hardy Heron, and I've gotten it to work (I can open up the simulator and connect to it with playerv, at least). I have also installed three different versions of pyrobot, including the latest, and I have seen the same behavior each time (I may need to use Pyrobot 4.6 in order to communicate with the even older Pyrobot on my ancient Pioneer robots). I can start up the Stage simulator, but when I try to connect using Player.py or Player6665.py I get a playerc error. It does not complete the connection to the simulator, and I cannot do anything from that point on. I'm including a transcript that illustrates what happens. I'm using a fairly simple simulated world, just one Pioneer robot in it. The Pyrobot simulator works just fine, so far as I can tell. Someone posted about this earlier, and it was suggested that the robot is trying to connect to the port the simulator is using. But I don't know how to avoid that problem... The problem occurs with the world files provided with Pyrobot, and with those that came with Stage, and with those I created on my own. Could this be a Player issue? I ran the tests that the Player installation called for... I appreciate any help you can provide... Thanks, Susan Here is the transcript: ----------------------------------------------------- macales...@zorro:~/Desktop/Aug2007Vers/simulator$ pyrobot -s StageSimulator -c olin.cfg Using PYROBOT on posix with CPU 0 in '/usr/lib/python2.5/site-packages/pyrobot'... * Part of the Player/Stage/Gazebo Project [ http://playerstage.sourceforge.net]. * Copyright (C) 2000 - 2006 Brian Gerkey, Richard Vaughan, Andrew Howard, * Nate Koenig, and contributors.
