p2os

The ROS stack for hooking up to the pioneer

I (anna) haven't gotten this to work because of my usb issues, but according to Jonathan, when you do:

$ rosrun p2os_driver p2os

if you get an error like

P2OS connection opening serial port /dev/ttyS0...

this command should fix it:

$ rosparam set p2os/port /dev/ttyUSB0

after starting the p2os driver and everything, you can control the robot via keyboard with:

$ roslaunch p2os_launch teleop_keyboard.launch


slam, etc

this diagram is important http://www.ros.org/wiki/navigation/Tutorials/RobotSetup?action=AttachFile&do=get&target=overview_tf.png

currently we don't think we have any sensor transforms

tf references a "world frame" -- is this our map?
