[Mindstorms] [MOC by AC] 遙控 Lego 船 - 真係可以"放船仔"!

[MOC by AC] 遙控 Lego 船 - 真係可以"放船仔"!

This is the 1st time I publicize my MOC. All comments are suggestions are warmly welcomed.

MOC - Remote Controlled (RC) Lego Ship (that really moves ON WATER!)

 

NOTE: v2 updated here: http://www.minifigs.net/forum/viewthread.php?tid=35841&page=1&extra=page%3D1#pid424899



How did I come up with this idea?
Last time I made a helicopter (that has fast spinning rotor but can't fly of coz...) with Mindstorms, so I figure out if lego can't fly, it may float...

What are the Important parts?
- Hull of set 7994 - only this hull is large enough to house the motors + remote + battery + Mindstorms expansion (that I'll add later)
- Power Functions (for RC and power)
- TONS of gears (self explanatory in the photos)
- Technic parts
- Rotors that can house "+" axle (not "o" one)

How does it work?
- 8884 gets 2 separate signals from 8885
- Each signal drives individual 8882 (XL motor) which is ON THE BOAT (not under)
- Power transmitted to underwater rotor through CHAIN OF GEARS (you might come up with different methods but believe me, this is the most reliable and sturdy one)
- 2 Rotors in same direction - forward or backward.
- 2 Rotors in different direction - turn left or right

What's Next? (Not here yet - will be implemented next stage)
- Cannon (similar to Mindstorms Shooterbot) on board that shoots 10mm marbles (max range 6m - tried)
- Adjustable cannon mount controlled by Mindstorms NXT
- Remote control through Bluetooth from another NXT brick with Gyro sensor to control aiming of cannon in joystick-style

Btw I'm too lazy to decorate and polish it yet, so it appear a bit "empty" - what I wanna try here is to make a real ship with RC - everything else can be added later as there are plenty of space on board

有冇試過轉用LEGO出的螺旋漿?

另外船的速度如何,能否拍片分享?

Thanks for suggestions

 

(1) Video clips uploaded and in the contents above.

(2) Ship upgraded and new videos/photos in next thread here: http://www.minifigs.net/forum/viewthread.php?tid=35841&page=1&extra=page%3D1#pid424899

(3) You're very sharp - the propeller is the most critical part of this design... I know there are such parts (3-blade propeller with "+" axle) but I just can't find it... I have searched in In's Point and Kai Wong mall but in vain, and that's why have to use this "home-made" propeller... speed of the ship is "baby-crawling" speed because (a) it's only geared up 3 times and (b) the propeller piece is not quite fluid-dynamic. Nevertheless imma try order it from Lego US website and have it shipped to HK, and after that I'll try further gear up to 9X. Hopefully it can achieve "baby walking" speed.

 

I also inserted a partition to separate the 2 propellers in the version 2 ship (next thread) to reduce turbulence. The improvement is surprisingly significant and the cracking noise (when both are rotating) is eliminated.

 

Do you know where to find the propeller piece in HK? Thanks!
