ATI has provided the source code written with Java.If you read it,you will find that it just got data by sockets.First,s

That's ok,I will edit the answer later.

I am doing a project about robot-teleoperation now. By using ROS I have accomplished the position-control（even though there are time-delay between the master and slave）.I find that the position control is not flexible enough,so I want to control the robot with velosity-control .After reading the explaination about link text ,I learned that maybe it's possible to control the jointspeed. After I

 roslauch ur_modern_driver ur_driver

and

 rostopic echo /ur_driver/jointspeed

There is no response anywhere,what's failure and what I should do to control the jointspeed? Any help should be appreciated!

oh,I got it.Thanks,gvdhoorn.By the way,I should use trajectory_msgs::JointTrajectorydirectly instead of control_msgs::Fo

Dear friends: I have built two nodes :main and listener. The main nead to read (x,y,z) from a device and publish to the listener. The main code can read the data but the listener can't get the published data now,and i even don't know whether the publish is success,how should i handle it? Thanks for you help. The result of rosrun talker: X=0.013095 Y=-0.0524488 Z=-0.0401042

But the listener is like this: X: 0 Y: 0 Z: 0

The rosmsg show is: dong@dong-H61MHB:~/Project/robot_test$ rosmsg show rosfalcon/falconPos float64 X float64 Y float64 Z The source code of publisher

int main(int argc, char* argv[]) 
   { ros::init(argc,argv, "main");
    if(init_falcon(0))
    { 
        std::cout << "Falcon Initialised Starting ROS Node" <<std::endl;
       m_falconDevice.setFalconKinematic<libnifalcon::FalconKinematicStamper>();
       ros::NodeHandle node;
       ros::Publisher pub = node.advertise<rosfalcon::falconPos>("falconPos",10);
while(node.ok())
     {       boost::array<double, 3> Pos;
            Pos = m_falconDevice.getPosition();
            rosfalcon::falconPos position;
            position.X = Pos[0];
            position.Y = Pos[1];
            position.Z = Pos[2];
            pub.publish(position);
            std::cout << "X="<< position.X<< "  Y="<< position.Y<< "
Z="<< position.Z << std::endl;      
            }
        m_falconDevice.close();
    }   return 0;
    }

And the main part of listener is:

int main(int argc, char *argv[])
{
  ros::init(argc, argv, "listener");
  ros::NodeHandle node;
while(node.ok())
{
  ros::Subscriber sub = node.subscribe("position", 10,&positionCallback);
}
  ros::spin();
  return 0;
}

I did rostopic echo and found that my publisher didn't work.I guess that there are something wrong in my cmakelists.

yeah,I found the my topic name is wrong.It should be same,and the first one is not the fatal error.Thank you.
