I'm trying to install a hard realtime kernel in Lucid for some robotics work. My preference is RTLinux ( by Wind River Systems. I also see that there is a package by the name "linux-rt" in the repositories, and its description is: "complete Realtime (RT) Linux kernel".

My question is: are these two the same? If not, what are the differences between them and the pros and cons of each?

From the faq, the linux-rt kernel is no longer maintained, and is (was) based on the ubuntu (patched) kernel.

The page you referenced, RTLinux, looks like a separate project, based on a non-ubuntu, vanilla kernel.
