As a Reconnaissance Soldier myself, I too think it’s pretty funny. Although the price isn’t all that bad if it could do what it shows. Although it’s size alone would be a huge drawback. Since you could tip a fridge in front of it and it wouldn’t be able to get past. lol
Since the Robotex AH is nothing more than a “concept video”, they might as well make it fly and become invisible. 
I don’t think that project will ever get off the ground [size=59]u thread-jackers[/size]

Final version of the finished MARC Robot:

Taken out in the snow. No harsh shadows and the snow makes for a clean white background. Proffessional eh?
Italian_guy299,
Nice work. Looks very professional.
By the way, where did you get the Airsoft Uzi?
Is the mechanism all metal or is it plastic?
Regards,
TCIII
Thanks TCIII,
The gun is a Crossman M70 airsoft gun which shoots 6mm pellets. Unfortunately I wasn’t able to get it to fire very accurately becuase the recoil makes the servo struggle to hold position.
I bought it at my local Canadian Tire:

Italian_guy299,
Unfortunately your link ask for a postal code before it will proceed to the website and I do not have a Canadian postal code.

Italian_guy299,
Thanks for the Walmart link. Much appreciated.
Here is an interesting website concerning the Crossman M70 gun and several links showing how to cut the gun down to a smaller size: tgi.net/~andrew/?p=22

Interesting. Originally I planned to mod the gun, however I decided not to for safety reasons. There are rules I have to follow when entering my local science fairs and all these rules must comply with CWSF (canada wide science fair). To make it there I have to follow these rules. 1 being not to modify guns/ammo(this is considered a gun by CWSF since you must be 18 to purchase it).
You would probably get better accuracy and control if the gun mount was ridgidly mounted to the bot and the gun tilted on the mount itself. Look at the below setup to see how to tilt a mounted object using a simple linkage. This would allow for much finer aiming and the gun would be steadier on the mount. Bottom is the UZI which might be more compact.

Thanks for the comments guys. Its too late to change my project for the science fairs, but I plan to continue with this project until I am satisfied with its performance. Its a project I am very fascinated in and will be complete when I say so
UPDATE: It is kind of a late announcement, however, last week the MARC took home a gold medal in my school fair. I’ve just completed my registry for my regional fair and if all goes well I may end up with a gold there as well a long with the grand prize to Ottawa for the Canada-Wide Science Fair (won that last year).
BTW: i just recently downloaded Google Sketchup and I must say it is very good! Its not exactly a 3-D imaging program like autocad, but it is very good for modeling chassis’ etc. I highly recommend it to newbie CAD drawers.
Heres my first CAD ever:

Its pretty good however it isn’t to scale as I just learned how to measure lines etc using the tape measure tool. Over all a very good and user-friendly program.
Got any pics of the medal?
Google Sketchup is quite simple. Thats the first program I used. Very quick, easy to use interface.
Looks cool and congratulations.
You can do some pretty intense things with sketchup. Depends on how good you get at it. I hate that it doesn’t have drill points though. And it has serious issues with exporting DWG and DXF files.
yes, I wish it had drill points too.
And heres the gold:

Nice!
Congratulations! Keep up the good work!
Thanks Zenta, Cudos for winning the Trossen Robotics competition as well! 
Here is the final project for my regional fair this week:
