Let's Make Robots!

Icebreaker Lenin


I started this project this summer. It's a model of the Russian Nuclear Icebreaker Lenin. Originally I was going to use cupper as the skin but I had difficulty fixing it to the rib so I decided to take the easy way out and use fiberglass. The ship will be a robot in the sense that it will have DP 2nd class. What this means is that it will be radio controlled with the ability to hold position and move to specified co-ordinates while holding the desired heading just like a real ship would. The position will be held using a compass, GPS, and either a laser or sonar. I might take it one more step and also set up a taut wire.

It is to bad you can't have like a pocket fuel cell of some kind. That would add a very nice feature and practicly limitless power. I wonder how long it would take before the battery's are flat at full power with all electronics and two of those lights. The lights would be a real nice touch by the way;-)

The vessel will have two motorcycle batteries and so they will last for a long time. If I used fuel cells which need hydrogen and oxygen to produce electricity, I would need a lot more space to run the vessel for the same amount of time as the batteries. The cool factor would definitely be a lot higher.

Would one of these qualify as a pocket fuel cell? Only 54x54x25mm for the double back-to-back cell that I used.

It did start its service in 1959 and finished in 1989.

I wanted to build this ship since I got the plans 13 years ago.

That ship has got an odd hull shape. Very Russian. i like soviet and Russian machines because of their style and shape.

I just put on the first layer of skin. I will add 2-3 more after this dries completely and the rudder assembly is added on the back. I put just one layer on so that I will be able to clean up any problem spots and make sure there is no mistakes.

Your hull looks great. I’m building a plug for a fiberglass mould that seems to be about the same size (120cm). I need two hulls since I am building a catamaran  version of the Whirligig http://letsmakerobots.com/node/16995.

Maybe I should have used your approach and covered the bulkheads with fiberglass instead of filling the void with foam.  Too late to change that now. I’ll get there anyway J

This looks good!

My initial idea was to have the whole thing made out to metal. I was going to have the ribs cut from steel or cupper with a water jet cutter and cover it with the same material. I then change to having the ribs out of plywood and just cover with cupper but when I was securing the cupper to the ribs it was splitting the ribs even though everything was predrilled. So in the end I decided to just stick to fiberglass. If I went the fiberglass root from the beginning I would have taken your approach and made a negative then a positive impression. You don't have to compete with ribs and any imperfections would be eliminated in the negative stage.

Hello and thanks.

 

The ship will be made to spec so it will have 3 props and one rudder. I believe the real one had bow thrusters but my plans don't show that so I do have some searching around to do. Also I'm not 100% sure if the Lenin had DP but that is a feature that all the vessels that I work on have and it's a really cool one so I decided to put it on the Icebreaker.

 

As for the ribs in neat little order. There is a 5 foot long wing just above the picture from a piper cub which maybe one day can be turned into a drone.

What motor(s) will drive it?
