I was just wondering if anyone has had (or even tried) making a successful floating boat (not using the "Boat Really Floats" pieces)? -- Clay Aucoin (25 years ago, 14-Jun-99, to lugnet.robotics, lugnet.build)

(...) I've considered using empty air tanks from pneumatic LEGO sets as sort of 'pontoons'... my one quick test of this so far was too top-heavy (I only have three air tanks), but it seems like it should work, as long as the floats are far enough (...) (25 years ago, 14-Jun-99, to lugnet.robotics)

When I was a kid Lego boats came with a large keel piece which was quite heavy (filled with iron or lead?) and effective at putting the CoG below the water line.

A few came back. One was to use the pnuematic air tanks, sounds good but: 1. the only way to get them is to buy complete usually expensive) sets. 2. they probably wouldn't allow the boat to go very fast. Another was to put a plastic bag at the (...) (25 years ago, 15-Jun-99, to lugnet.robotics)

(...) The boat could probably still go pretty fast using the air tanks, I think. The problem with the plastic bag is that you're using non-LEGO pieces and you may as well go buy a chunk of RC modeler's blue foam and carve out your own hull. E² -- (...) (25 years ago, 15-Jun-99, to lugnet.robotics)

I was kind of looking at a twin hull "speed" boat design powered with the LEGO props. Now I know that it might not go very fast, but it's just something that I enjoy, remote control boats! I've never actually owned one, but a friend use to build the (...) (25 years ago, 15-Jun-99, to lugnet.robotics)

Actually, if this is your idea, i used to play w/water rockets when i was a kid, but i don't know if any1 still sells them. It is a light plastic rocket about 4-12" long, filled halfway w/water, & pumped w/air from the bottom, & then launched by (...) (25 years ago, 15-Jun-99, to lugnet.robotics)

(...) Some complications i would see w/this is that #1, u would have to use it immediately after pumping because there is no way to stop the air-flow (unless u could cork it w/a needle or something). #2, it will probably not propell the boat evenly.

Since I wrote this, I've seen the setup in person. The Palm V's are connected serially to a Sun PC which broadcasts IR from a standard Lego IR tower to the tanks' combat arena. The messages sent to the tanks use 3 bits for the tank id and 5 bits for (...) (25 years ago, 18-Jun-99, to lugnet.robotics)
