Thanks for your help.

I ran into a little trouble while connecting to my Pioneer 3 AT. Using p2os stack.

I am using a USB-to-serial adaptor to connect to the Pioneer, in a Ubuntu machine, the same one running roscore. I changed the source code of p2os_driver to use ttyUSB0 instead of ttyS0 (changed the define).

The main problem is that when I start the p2os_driver, i connect to the pioneer succesfully, but once the driver gets to:

Connected to PIONEER NAME, a Pioneer p3at-sh
[ INFO] [1282927100.884548427]: resetting raw positions

The robot starts beeping, with the same sound that happens when a connection is lost. Even though I can read the battery level. Nothing happens when I press the motors enable button on the dashboard, and I cannot teleoperate the robot using a joystick.

Any insight?

PS: i can connect to the robot using the same adapter via Carmen or Player.



Keep Creating,

Pablo

I cannot vouch for the ARIA approach, however, as the developer of the
p2os stack, I can say that we have launch files for doing SLAM with
the gmapping package and for using the move_base node as part of the
nav stack.

There are some pretty good instructions at:

http://www.ros.org/wiki/p2os/Tutorials/Getting%20Started%20with%20p2os

and please email the ros-users list if you are having issues and I
will be happy to help work them through with you.
