p2os

The ROS stack for hooking up to the pioneer.

Installing

http://www.ros.org/wiki/p2os/Tutorials/Getting%20Started%20with%20p2os After following the directions above, we have to set the p2os/port to our cable's device name:

$ rosparam set p2os/port /dev/ttyUSB0

Running

Run on the base:

$ rosrun p2os_driver p2os

Run on the computer controlling the base:

$ rosrun p2os_dashboard p2os_dashboard

If you get an error like:

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

This command should fix it:

$ rosparam set p2os/port /dev/ttyUSB0

robot commands

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?
