If possible use all the same fastener or as much of one as possible because you will spend less time looking for tools if they all need the same allan key and box wrench. You can minimize loose parts by using flange head bolts to eliminate washers also.

The kitbot is standardized to take 1/4-20 hardware. The accompanying screws are SHCS. As has been stated, if you make everything SHCS, you won't have to worry about phillips/flathead screwdrivers (students always grab the wrong kind). With the exception of the electronics and drive axles, we exclusively use 1/4-20. We also buy about a dozen allen key sets each year - the tools tend to get rounded or lost. I'd recommend the kind where all keys are connected together like a pocketknife - the individual parts are less likely to get lost. We also get about a dozen 1/4" drill bits - they tend to snap at the most inopportune times. (I know, if used properly, drill bits shouldn't snap - but I also know that teenagers tend to test the boundaries of "should")
IIRC some of the electronics take 8-32 hardware, and axles are 3/8-16; plan accordingly.
Ratcheting gear wrenches are awesome. Especially the kinds with flexing heads.
In addition to the plywood, get some 10' 2X4s. Like 8 or 10 of them. They'll be probably used in the field. It would be a great task for the parents to build the key field elements the first week.

Re: 2 robots: Don't worry about it. One robot is more than enough work. Lots of respectable, competitive teams do it with one robot. That's not to say don't build two - the advantages are numerous - but don't kill yourselves trying to get two. Focus on Number One, make it right and good.

Re: NEW TEAM NEEDS

Here is the 2011 Kit of Parts, it will give you an idea of what has come in the KOP in the past and what might be in this year's KOP

Re: NEW TEAM NEEDS

Tools.

Hand tools like screwdrivers (get 3 sets), wrenches (2 sets), a socket set, hacksaws, files, lots of pliers (including a cutter for #6 copper wire), aviation shears, center punches, hammers, and so on. Anyone who is handy at home will imagine what you need. If money is tight - and where isn't it? - order all that from harbor Freight to start out, then replace stuff that fails with better stuff later. Oh, and a tool box or three. Pop-rivet gun and rivets.

Chain. #35 chain, along with lots of master links, half links, and a chain 'breaker'. Sprockets can come later.

Lexan. NOT Plexiglas (Acrylic) but Polycarbonate. 1/16" thick for decorations, 1/8 & 3/32 for structural elements. 4' x 4' sheets. Also 0.062 and 0.093 aluminum sheets, 2'x4' should be good.

Drills, and drill bits. NOT TiN coated, this isn't great for aluminum. Also a big step bit for when you need to drill a 1.25" hole in a sheet of something. Get extras of the small (under 1/4") sizes.

Power tools like a drill press and a power sander (small belt or disk), and if money allows a metal-cutting band saw for thin sheets, a cold saw (or, if you like to live dangerously, a far-cheaper chop saw) to cut extrusion, an air compressor to blow and inflate things, maybe a lathe and mill....

A vacuum cleaner. For all the metal chips. Broom and dustpan too.

Electronics tools, like fine hand tools, a soldering iron and solder, a ratcheting terminal crimper (mandatory) and lots of extra high-quality terminals (yellow, blue and red, mostly fork and ring terminals), a good wire stripper, several rolls of 3M black electrical tape and a roll each of several colors. Heat-shrink tubing kit, and a heat gun.

Rolls of electrical wire, automotive type, copper. Stranded, red & black, in #10 & #12 (50' each), #14, 16 & 18 (100' each), and some #20 or 22 in red, black and white. You'll use it all, but it'll get you going.

Storage shelves, plastic cheapies are OK, but kids need places to put their work in progress. Bin boxes too, even old liquor boxes will do. A way to organize your supplies, even just a little.

...-.-

The one thing that saved our butts more often than ANYthing else? An open account with McMaster. They deliver UPS overnight, and sell almost everything.

Do you have a farm store nearby, the kind that deals with machines like lawnmowers or combines (not sure how rural you are...)? A WalMart? Sears? Farm Supply? Ace Hardware? All of these will be your friend.

Check the yellow pages. There HAS to be a machine shop within an hour. They can help you find where to get stuff too.

I'm sure there's loads I forgot, but that'll get you started.

Re: NEW TEAM NEEDS

this may sound very basic but you can never have enough duct tape and electrical tape. Duct tape if anything can be used to hold carpet together for practice. Electrical tape will be used a lot for batteries and such. A box cutter is always a good idea to have around. Also keep a small first-aid kit (latex free if someone is allergic) and a fire-extinguisher around not only for your safety, but also for safety judges at competition. Sharpies and dry-erase markers are useful to mark basic lines on metal ( I have even used liquid white-out), though you dont want to use them if you need really precise cuts. Allen wrenches (both L and T handle) are both useful. Pencil and Paper to make hardware store- run lists. Once you find out the challenge you will probably want to build a mock field to practice on, which can often be made out of wood, so you could possibly talk to a local lumber yard about donating that . Most importantly dont be afraid to ask for help. This site is my best-friend during build season. Good luck and I hope you have a great season
