Well, I blogged about it, and wanted to make sure I shared it with the folks
that inspired me (LUGNET). I've never been really interested in LEGO boats,
because in the first place I couldn't see much use for them (guiding a robot
over featureless water being... somewhat challenging), and in the second place
an all-LEGO solution was hard to come by... but then LEGO released new sets with
floating hulls, and I got interested again. so I put together "Serenity", a
proof-of-concept NXT-based water-craft:
On NXTlog:

or for a shorter URL that will still get you there:
http://mindstorms.lego.com/nxtlog/projectlist.aspx?SearchText=serenity
I've also got a YouTube video up. Sending a completely autonomous craft into the
drink was... well, a leap of faith:

I also blogged about it on theNXTstep (http://thenxtstep.blogspot.com/), but
I've not yet put up any more pics on Brickshelf. Critical to making this work
was the compass sensor, as with that I've finally got a way to at least judge
direction on a featureless plain of water. Now if I can just hack a GPS into
this and expand the base, I could get it out on a proper lake...
PLMKWYT, and while we're at it, looking at the above scattered list... dang,
maybe I ought to enter the 20th century and get my own website. Huh.

| (...) Nicely done! Next I wanna see an autonomous NXT controlled sail boat ;) Actually, the name would probably suit a sail boat more... (...) Nope can't waste time on that when you have a sail-boat to build! ROSCO (18 years ago, 12-Sep-07, to lugnet.robotics)

| (...) Wow Brian, that looks cool. I never thought of making a NXT boat. If I did I would probably not let go anywhere much other than a bath tub, it's pretty brave to take it out somewhere. I'd be worried about recovering the craft if the batteries (...) (18 years ago, 13-Sep-07, to lugnet.robotics)

| (...) Brian, ... absolutely cool ! I would like to attract your attention to a rather old Italian site (1999). (URL) Riccardo built a marveleous non-LEGO robot-boat equipped with electronic compass and GPS and travelling over the "Idroscalo Lake" (...) (18 years ago, 13-Sep-07, to lugnet.robotics)
