I am basically setting up this control framework for use with EtherCAT enabled devices (I will do the setup for EtherLab, and ROS), so I am looking for hard real time requirements - the system will be used for robot control primarily. I have searched the internet for RT-Preempt kernel based installations, but have heard that there is a significant latency introduced into the system. At this point, I can't really comment on how that would affect any specific performance objectives, so I thought of trying out Xenomai from the word go. </span></div>

Hi Ankit,<br>
<br>
what are the real time requirements of your application? You may try
the RT-Preempt kernel and have a look if it fulfil the real time
requirements. It is much easier to develop real time software with
it, as with Xenomai or RTAI. We use the 3.2er Debian RT-Preempt
Kernel from the Debian repository in Ubuntu 12.04 to control a 4 to
6 DoF robot arm with joint elasticity in combination with Orocos to
build up the real time control and ROS for network communication
between different parts of our software, and it works well.<br>
<br>
Regards,<br>
Jürgen<br>

<div dir="ltr">Hi,
<div><br>
</div>
<div>I am working on setting up a real time control framework on
my machine with Ubuntu 12.10 installed (Linux
3.5.0-17-generic). I have tried using the RTAI package but I
have had a series of failures while trying to get that to work
(it expects a Linux kernel of 2.6.35.9). </div>
<div><br>
</div>
<div>I am planning to use Xenomai to set up my real time kernel
and then install etherlab. With the same requirements of
etherlab for linux kernel, what should I do to make this
installation hassle free? Should I install an older version of
Ubuntu and configure it with a similar Xenomai kernel OR would
a 3.5.7 xenomai kernel work with etherlab installations?</div>
<div><br>
</div>
<div>I am confused between these compatibility issues and will
be really grateful if anyone could help me out.</div>

<div>Thanks,</div>
