p2os TCP instead of serialport/usb [closed]

edit

Hello,

I would like to use the p2os stack to interface an Amigobot, which is an Adept MobileRobots (ActivMedia) robot. This robot uses ARIA as firmware, and so do Pioneer 2/Pioneer 3 (DX and AT). According to http://www.ros.org/wiki/p2os/Tutorials/Getting%20Started%20with%20p2os a computer fixed to the robot is required. I was wondering if the p2os_driver also supports to connect via TCP to the robot instead of using a serial/usb interface.

In robot_params.h I could see these defines

/* conection stuff */ 
#define DEFAULT_P2OS_PORT "/dev/ttyS0" 
#define DEFAULT_P2OS_TCP_REMOTE_HOST "localhost" 
#define DEFAULT_P2OS_TCP_REMOTE_PORT 8101

I guess the DEFAULT_P2OS_TCP_REMOTE_HOST refers to the port where to publish messages? Is it possible to set the DEFAULT_P2OS_PORT to an ethernet interface?

I would like to run both nodes, p2os_driver and telop_keyboard on a laptop an have p2os_driver sending the commands to the ARIA firmware via wlan. Is this possible?

Thanks for any hints,

BR

EDIT:

Do you mean setting tcp_remote_host and use_tcp with rosparam set ? If so this didn't work for me. p2os still tries to establish a connection using the serial port.

rosparam set use_tcp true rosparam set tcp_remote_host 192.168.1.15 rosparam set tcp_remote_port 8101

I have also tried to use ROSARIA, the ARIA Port to ROS. In RosAria.cpp I found this in the Setup routine

    int RosAriaNode::Setup()
{
  ArArgumentBuilder *args;
  args = new ArArgumentBuilder();

  size_t colon_pos = serial_port.find(":");
  if (colon_pos != std::string::npos)
  {
    args->add("-rh"); //pass robot's hostname/IP address to Aria
    args->add(serial_port.substr(0, colon_pos).c_str());
    args->add("-rrtp"); //pass robot's TCP port to Aria
    args->add(serial_port.substr(colon_pos+1).c_str());
  }
  else
  {
    args->add("-rp"); //pass robot's serial port to Aria
    args->add(serial_port.c_str());
  }

I tried to run RosAria using this command:

rosrun ROSARIA RosAria -rh '192.168.1.15' -rrtp '8101'
NonCritical Error: ARIA could not find where it is located.
[ INFO] [1350643787.727256660]: using port: [/dev/ttyUSB0]
ArLog::init:  File(aria.log)     Verbose     Logging Time    Not also printing
setup failed...

Still Rosaria seems to ignore any arguments passed to it.

Do you have any clues?
