Robot Challenge

I finished my first complex NXT programming project tonight. I wrote it with NXT-G -- the programming environment that comes with the NXT.

It rolls a die randomly, and draws it on the screen, as you can (sort of) see in the picture to the right.

The main program ("Draw Die Test") just chooses a random number from 1 to 6, and then calls a "My Block" called "Draw Die" to (drumroll, please) draw the die. This is the most complex code because there are seven different "spot" position that make up the various die drawings. I actually pretend like there are nine, not seven, so I can do computations assuming a three-by-three grid, numbered from zero to eight. Spots one and seven are never used.

Not quite as complicated, but still using a number of math functions is the "Draw Die Spot" block. It draws just one little circle, in one of the nine positions.

Finally, there is no built-in modulo division function (% to C-language programmers), so I had to steal write a block for that. It's called "Mod".

You can dowload the program here. If you have any questions, please post a comment.

Update: As of 1/8/08, the folder is still not public on BrickShelf.
You can download the four necessary programs here, here, here and here!
