United StatesDid you try putting the full specification for it in the field?
http://www.roboticage.eu
Folks have gotten lazy in leaving off the URL prefixes. They assume the http part. There are other forms of URLs, with different prefixes.
As a followup, I used the Edit function and set my blog to www.roboticage.eu just to confirm the message appeared. Then I set it to http://www.roboticage.eu Yup. Worked. Then I unset it again.

Melbourne, Australiawww.roboticage.eu is not a url, its an address (ie it resolves to75.127.69.109). http://www.robticage.edu/ is a url. Web browsers assume http since it is the most common protocol in use. The protocol tells people how to actually talk to the address.
As MrScott mentions, there are several other protocols.
for example...
https://www.paypal.com/ - Secure (ie encrypted) http
ftp://ftp.au.debian.org/ - File Transfer Protocol
mailto://not@an.email.com - email
gopher://wwww.michaeleshun.4t.com/ - gopher, a text based predecessor to the web
telnet://www.robocommunity.com:80/ - telnet
http://www.robocommunity.com:80/ - hyper text transfer protocol, but with a port number.
All of these are valid URLs. Not all of them will work with most browsers (without adding handlers), but they are still valid URLs.
I forget if you need the trailing / for it to be a technically valid URL or not. Several of my friends poke fun at me because I always use valid urls. Then again, if they worked with html in a text editor, they wouldn't be laughing.

United StatesRegarding the trailing slash; if it is not supplied the web server actually errors out. Using http://host.name gets your browser to the machine, and the server says "you didn't ask for anything, try http://host.name/" using a 302 error (formerly "302 Moved Temporarily", now "302 Found" and used incorrectly instead of the more correct "303 See Other")
It's probably not noticeable to humans, but failing to use the trailing slash in a browser request takes longer, as it's actually having to perform two lookups instead of one.
To be really obnoxious, according to the W3C (whoopee doo dah) use of the term URL is deprecated and should no longer be used, replaced by the more correct URI, since all URLs are URIs.
No, I'm not really that picky about this stuff, I still use the term URL :)
Watch out, don't step in the anthropomorphization.

Melbourne, AustraliaTrue, though most browsers add a trailing / as well these days. Though that doesn't mean that a trailing slash is required for it to be a valid URL. Since, if you add a trailing slash to a mailto, the training slash is included as part of the address.
Its required with http, since otherwise (as you pointed out) you are not actually requesting anything (GET / being the lowest).
