Whoa! lasers! There are two ways of getting past this. The simple way is use 
Jep with the dynamite and blow up the BOX. 2) Use Jep with the Screwdriver and
solve the puzzle.

The Puzzle might look difficult but its actually very simple, All you have to 
do is make sure all the green lights are on. But how? Well, make sure that each
light has in some way a connection to the central ending node! Just play with 
the red buttons. And you will get it. 

My combination was 



                      v < > < >  
  
                                 ^   
                                 < 
                                 >
                                 ^
                                 < 
 

Well I hope decoding the above signs isnt another puzzle for u guys.hehe... 

Its the Direction the tip is pointing. If you have trouble Deciphering it, just
go to http://www.geocities.com/amalrajshetty/1stpuzzle.JPG . 

So now the Lasers are off, We go further down and see another robot, albeit its
broken. Mina doesnt want to destroy it instead she wants to decode it and get 
the stuff out. Alrighty, we try to decode it.

So you racked you brains enuff? Well its the 1st puzzle, so decoding it should
be that much easier. Just remember all the puzzles have to do with the word 
NAUTILUS. 

The way to go about any combination puzzle is just put a single number for all
letters. So say we have  A U L S    ...well just mash a single number for all 
of them , hmm, say 3 3 3 3 . Now If you are lucky it will show up a green on 
one of them. Just remember the corresponding Number and letter. So in this case
its U = 3. Do the same again for another letter, make sure u dont put 3's coz 
its already known for U. Say you get A=2. So A=2 , U=3 , T=4 .....sounds like a
series... Could it be
  
         N =1  A=2  U=3  T=4  I=5  L=6  U   S=8            

Now since we alreday have U=3, we cant have U=7. Also to make up for that 
extra U , they have put in another letter V. remember V =0


So the sequence is       N=1  A=2  U=3  T=4  I=5  L=6  S=8   V=0


Wow you cracked this one too! The thruster comes off and the key falls off. 
Grab them.

Now you have 4 keys.. so 4 crystals. Return back to the Nautilus. Combine all 
the 4 crystals with the Key and vallah! you have a new key! Use the Key on the
Key slot.
