I'm am interested in putting together another order for the 6811
processor for the miniboard.  I talked to someone at Active this
afternoon who said that they have 2600+ in stock, ready to ship.
This sounds a bit too good to be true; I will call again tomorrow to
double check, but wanted to get this rolling anyway.  Orders must be
for entire rails, in this case 23 units.  I need between 4 and 6 for
myself, so I'm looking for another 17-19 orders.  Send me email if
you're interested and I'll record orders.  The price I got from Active
was $18.50/ea.  Unless people really object, I'll make it an even $20
which will include shipping within the US and Canada.

Make your reservation now!

Might I suggest, 'a funding of robots'?  This is, you will be quick to
observe, fully in keeping with the political zeitgeist: it seeks to
enshrine hope.

When I searched in the library computer, I came across following record:

"Title: Mobile robot map making using sonar.
 Author: Zelinsky, A.
 Corporate Source: Univ of Wollongong, Wollongong, Aust
 Source: Journal of Robotic Systems v 8 n 5 Oct 1991 p 557-577
 CODEN: JRSYDB  ISSN: 0741-2223"

The abstract describes that the article deals with a method of producing high-
resolution maps of an indoor environment. The method is based on investigating
straight line segments extracted from the sonar range data describing obstacles
near the robot. The mobile robot then moves parallel to the straight line sonar
segments, in close proximity to the obstacles, continually applying sonar
barrier test. This determines whether or not a sonar line segment is a true 
obstacle edge or a false reflection.

Sounds interesting, doesn't it? Unfortunately I don't have access to this
publication myself. Would anyone who has, like to reply to me?

There does seem to be a persistent tension associated with this topic.
Maybe the solution here is to create a "comp.robotics.hardware"
newsgroup.  There appears to be enough interest, and I have to admit
that I, for one, try to skip over the hardware-related articles and
concentrate on the "softer" stuff, or more general issues pertinent to
robotics.

I am also looking for users who can relay mail to non computer

This idea sounds good until you consider the amount of work involved.  How many
sites are there?  Each one of us placing a call on a map keeper.  I guess it 
could be automated.  But then, so could checking for dupes.

I for one am against renewing map addresses.  Its like applying for the same 
street address.  Geese.  I don't even have to renew my drivers license more 
than once every five years.

Then of course you have the problem of an administative error where a whole 
block of map addresses get screwed up.  I tell you, your proposal could become
a night mare.  Regards, Terry.

	Well, since UUCP *per se* is NOT a mailer, but a simple file
transfer protocol for point-to-point dial up connections, UUCP has no
business trying to be a mailer *per se*

	Now, most UUCP packages *should* have the capability to respond
to the sender when a uucp request gets hung in the queue and doesn't get
dispatched in a reasonable length of time.   In this case, the UUCP
cleanup daemon looks to see if it is a mail message, and tries to inform
the original sender as well as the local administration.

	You forget also that a UUCP link is not necessarily
bi-directional!   Generally, if a site polls another, messages going in
both directions can be exchanged, but there are ways to break the
symmetry, and there may not be a mailer on the reverse link that
understands uucp syntax.

	Additionally, there are some sites that allow anonymous UUCP
connects with "rmail" privledge, which would allow any site to dump mail
bound for some site into the stream, but there would be no reverse
channel.

	This can be quite frustrating too.  Someone may dump mail into
your site via the anon uucp connect, and then wonders why you don't
answer their email request. :-(

	As another example, the recent flak over the link between
zuma.UUCP and antatolia was set up so that zuma could dump news into the
net, but not have a useable reverse channel.  This "convenient"
arrangement allows Serdar Argic to propagandize the net while not being
subject to any form of peer or social pressure for doing so.  (And this
arrangement also violates the existing Usenet/NetNews RFC's.)

I agree! I recently had a major disruption in service (that is still in
progress) due to a site in California that started using my site name
memalph. I need to know how to send a message to this guy. I have used this
site name for about 4-5 years and the new guy is starting to tick me off.

Why not have each "volunteer" uucp map maintainer set up a script that
emails to each machine in question on 6mo. or maybe one year anniversaries
of the original registration the requires the site to respond within a
fixed period of time (say 30 days) or the site will be dropped from the
maps.  Shoot, even the response could be automated and as long as the
site stays up, it stays in the maps.

In some parts of the world, like here in Ontario, you are legally
required to notify the appropriate authorieis when you change address so
you license can be updated.

However its not a fair analogy.  You don't have to notify the licencicng
authorities if you decide to stop driving and take the bus instead.

I'm in favour of a time-out period.
The administrators could just as well post reminders - like I get a
reminder to renew my license and plate sticker...

And mailing the reminder will see if it bounces and so give a strong
hint as to whether the site is around.

The other approach is one of 'mutual recognition of coresponsibility' to
use the old phrase from the '60s.  Keep YOUR maps acutrate and resubmit
when a site you connect to goes away.  The regional administrator can -
our does he tells me - run pathalias to see what is unreachable.
High probability of site that is either a typo or has no connections
'cos its gone away and everyone else has been diligent.

This used to fail if the interconnecting sites were using different
flavours of uucp.  It may work for you, but it won't necessarily work
for everyone else.
