I have successfully executed the command

rosrun robot_upstart install myPackage/test.launch

and also

sudo systemctl daemon-reload && systemctl start myPackage

But after I reboot or restart, I can confirm by using rosnode list and rostopic list that the nodes listed in the launch file never start. Starting the launch file using roslaunch works fine so that's not the issue.
Here's the content of test.launch

<launch>
      <node name='node' pkg='myPackgage' type='simple_node' />
      <node name='graph' pkg='rqt_graph' type='rqt_graph' />
</launch>

Update 1: Additional information:
- Starting the service manually doesn't work (even before reboot).

sudo service myPackage start

No error, but nodes don't run.
- Files installed during the robot_upstart install process are still there after reboot.
- There is no log file for robot_upstart in /var/log/
- There's only one user account, and logging into it I can see the packages and environment variables.

Update 2:
I tried launching a couple other nodes and they worked fine. But that one node which receives sensor data still doesn't run. (rqt_graph doesn't run either, but it doesn't matter since it's useless as a daemon.)

Glad to hear that!

AFAIK, the SOEM packages that are written specifically for ROS and OROCOS are available for Indigo. Still, you might be

Take a look at the Indigo tab of this tutorial. for ROS + OROCOS

Hello. The solution that I think might work is ROS Indigo + OROCOS + RTT_SOEM. I say "might" because I haven't tested it

Hello. The solution that I think might work is ROS Indigo + OROCOS + RTT_SOEM. I say "might" because I haven't tested it

I should also mention this tutorial and the following packages: rtt_soem_robotiq, rtt_soem and soem.

I haven't run this for a while, but I remember that it was working fine. Have a look.

In theory of Kalman filters, we should have a model of the system. For example, if we are using the "simple" Kalman filter for a linear system, the algorithm contains the following prediction step:

Here the matrices A, B and the input u are assumed to be known.
But in ROS packages robot_pose_ekf, robot_localization (and elsewhere), I have not encountered a code that actually asks the user to enter A and B matrices or the input u. So how do they get away with ignoring the system's dynamics?

I have been trying to implement a synchronizer with approximate time policy in a class. The following code compiles with no problem. But how should I define the Synchronizer and the registerCallback? (The two commented lines)

#include "header.h"
using namespace message_filters;
typedef control_sys::IntWithHeader myMsg;

class Node
{

public:

    Node()
{
    sub1.subscribe(node, "in1", 1);
    sub2.subscribe(node, "in2", 1);

}
    void callback(const myMsg &in1, const myMsg &in2)
{
        std::cout << "Synchronization successful" << std::endl;
}   


private:

    ros::NodeHandle node;
    ros::Publisher pub;
    std_msgs::Int32 out;
    message_filters::Subscriber<myMsg> sub1;
    message_filters::Subscriber<myMsg> sub2;
    typedef sync_policies::ApproximateTime<myMsg, myMsg> MySyncPolicy;
    // This is how I would define them inside main()
    //Synchronizer<MySyncPolicy> sync(MySyncPolicy(10), sub1, sub2);
    //sync.registerCallback(&callback);
};

int main(int argc, char **argv)
{

    ros::init(argc, argv, "synchronizer");
    Node synchronizer;

    ros::spin();

}

Update 1: Headers included:

#include <ros/ros.h>
#include <std_msgs/Int32.h>
#include <iostream>
#include <message_filters/subscriber.h>
#include <message_filters/synchronizer.h>
#include <message_filters/sync_policies/approximate_time.h>
#include "control_sys/IntWithHeader.h"

Update 2: Error output of catkin_make (in terminal)
