 dustpan with a roller on a servo. the roller works like a pickup brush on a vacuum cleaner and sucks robots into the claw and helps hold them in place.

Black Friday went like this for me:
Went to work at 12:01 a.m.
Worked until 7:30 a.m.
Bought 4 items from my own store (no line no wait wheee)
3 of them were items that a friend asked me to pick up for her.
Went home... slept from 8 a.m. to 1 p.m.
consumed some string cheese and an energy drink.
Went out to donate some items to a local shop that gives away stuff to poor families who can't afford gifts. (couple NASCAR cars / a CD Rack / some other stuffs)
Shopped locally and bought a couple unique crafted items.
got home at 4:00... poured a nice glass of porter.
T'is a good day so far.
:D
How is everyone else doing?
i've been off work all week because i work as a cook at a boarding school and they've been closed all week. :P i tried to black friday last night but that didn't work cause the line was crazy and i said forget it. today i bought a drill and impact driver and some other assorted hand tools.

so why exactly do you need heavy armor ?
from the sounds of it a bunch of people are entering non damaging sns and the wide design is good at stopping sns.

win about 4/10 of wedge on wedge with the original. might have to play around with counterweights but it's still stupidly wedgey.

dsl bars, beater bars, something less giant. take a look at real spinners and try to emulate their style. don't tell me you cant. i've seen how good at cloning you are.

picture from previous page for ease of viewing  the DSL Bars look a bit pointless.
but i build irl too much so dsl bars start looking good on everything Any specs/internals at all?
 npc, 4 ants, ti3, 799.7 also has ti 1/2 sheet bottom and 2 steel skirts for top armor. i originally had eteks and less weapon. thats why the drive setup is kinda stupid

you can make it smaller. if you can make it smaller is better because you can go thicker on the armor. you can use nutstrip for anything.
i don't like your plow because it will be a pain in the butt to make and attach. if you were to attach it you could probably have an internal vertical 1/2" thick uhmw wall and attach it with a pair of .25" lag screws. I'd personally go with a generic wedge instead of the plow shape.
also what is you experience with building things? i'm asking so i can help give you better advise about how to go about this project.

Are thwackbots legal in the 30lb Sportsman class?
no. the weapon has to function independently of the drive.

2 2s 300mah packs in series will get you 4s
i reccomend using nutstrip to hold the robbot togeather.
also your robot shape is still stupid.

I see:
Don't bother with Copals, they have plastic gears. I suggest the Finger Tech Sliver Spark motor. http://www.robotmarketplace.com/products/0-FT-SSPARK-50.html, I have the Gold spark motor, and it works great. Sliver Sparks have bigger teeth, reducing the chance of striping.
Don't bother with the mounts, they won't fit the sparks, even if they did, you would have to bond the mounts with a lexan surface. If you really want a mount, use a finger tech mount.http://www.fingertechrobotics.com/proddetail.php?prod=ft-bearing-block. It comes with a ball bearing pressed in, so it won't cause to much strain on the motor shaft.
The wheels are fine.
Dave's hubs are fancy indeed, but the Finger Tech hubs(http://www.robotmarketplace.com/products/0-FT-LITE-HUBS.html) will work just as well.
Avoid Tactic products. Use a Spektrum Dx5e(http://www.robotmarketplace.com/products/0-SPM5500.html) with the Hobby King Orange rx(http://www.hobbyking.com/hobbyking/store/__11965__OrangeRx_R610_Spektrum_DSM2_6Ch_2_4Ghz_Receiver_w_Sat_Port_.html). Costs less than that Tactic system, and will work far better.
That ESC is nice, but the Finger Tech Tiny ESC(http://www.fingertechrobotics.com/proddetail.php?prod=ft-tinyESCv2) is better. It works great, and are way lighter than the Saber tooth.
That battery is WAY over kill, that's a huge chunk of your allowed weight. A smaller battery(http://www.hobbyking.com/hobbyking/store/__18204__Turnigy_nano_tech_850mAh_4S_45_90C_Lipo_Pack.html) would be much better here.
You haven't selected a charger. I'd recommend the Turnigy Accucel-6 50 watt(http://www.hobbyking.com/hobbyking/store/__7028__Turnigy_Accucel_6_50W_6A_Balancer_Charger_w_accessories.html).
1/16 thick aluminum is way too thin, go with 1/4 thick UMHW plastic(http://www.onlinemetals.com/merchant.cfm?pid=12550&step=4&showunits=inches&id=785&top_cat=181), easy to work with, super strong, and light weight.
1/8 Grade five titanium heat treated would work wonders for a good spinner killer plow. Check Titanium Joe(http://www.titaniumjoe.com/6al4v%20sheet.htm)!
A good way to mount your stuff is high strength Velcro, of the highest quality.
Hope that helps you a little.
This helped a LOT, but I still have some questions:
-Can I get the titanium pre-bent and cut to size?
-How would I cut UMHW plastic? Also, how would I put all the armor pieces together?
-Aren't Hobbyking parts poorly made?
-Where would I buy the Velcro?
Also, some other notes:
-I had no idea copals used plastic gears, this info helped a lot.
-That tiny esc looks hard to work with, I wanted the sabertooth because it seems easy to use and there's a bunch of tutorial stuff for it at the robot marketplace.
sabertooths suck don't use them. hobbyking radio gear is badass. 850mah is way too big. you need 300mah. tops 1/8" ti is like 220 armor thick. you could do 1/32" and be fine. also your shape is stupid. try a more conventional wedge shape and see how that looks. you can buy velco at walmart you can bend 1/16" ti with a pair of plyers and a blowtorch. just heat up till orange and bend.
