Is there any way to get a FEN like string at a given position of the game.

I don't think any such thing is defined for Arimaa, but we could define it right now and it might become standard.
+---+---+---+---+---+---+---+---+
8 | r | | | m | | | | |
+---+---+---+---+---+---+---+---+
7 | r | R | c | D | | d | r | r |
+---+---+---+---+---+---+---+---+
6 | | | * | c | r | R | R | |
+---+---+---+---+---+---+---+---+
5 | h | r | | | | | d | |
+---+---+---+---+---+---+---+---+
4 | e | E | r | | | | | |
+---+---+---+---+---+---+---+---+
3 | H | | * | | M | * | R | |
+---+---+---+---+---+---+---+---+
2 | | R | R | | H | h | R | r |
+---+---+---+---+---+---+---+---+
1 | | | C | C | | D | | R |
+---+---+---+---+---+---+---+---+
a b c d e f g h
Imitating FEN from chess, the above diagram would (I think) be
r2m4/rRcD1drr/3crRR1/hr4d1/eEr5/H3M1R1/1RR1HhRr/2CC1D1R
If I may ask, why do you want to use FEN for Arimaa positions?

Sure  ,
I am playing a game here against ThePhantom, and posting at schemingmind.com forum. There one can only post position as a FEN string and corresponding diagram is auto-generated. I have already given the link to the game, but thought that addition of FEN diagram would be more appealing.

Very cool. Thanks for spreading Arimaa into yet another corner of the gaming universe! For the rest of you, here's the link I found:
http://www.schemingmind.com/topic.aspx?topic_id=30012
But why is black missing a pawn?
I input the FEN for the game so far to get you started...

Let me add one more item in the FEN . The next move
r2m4/rRcD1drr/3crRR1/hr4d1/eEr5/H3M1R1/1RR1HhRr/2CC1D1R G or s
G Gold
s silver
we can use capital or lower case. or black or white..
How we standardize it, depends.

In Beginning Arimaa, I proposed putting the move number and side to move in front of the position. For example 28s rrr2rr1/2cdcd1r/3h2r1/8/HDE5/1r2e3/RRCD2C1/1RR2RRR would indicate that it is Silver's turn to move, and even specify that move 28s is upcoming. But I have no idea whether my proposal is reasonable or not, because I have never needed to record a position in condensed fashion.

Wooow this is nice idea of 28s on friend !!Bravo!! i didn't thought of that
I see that bot can use the FEN notation to get the board position and sent the best move back to the front end.
not sure how current bot works.
and I yet to buy your book  but will do it soon
