Carpet at Competition

[Hebrew]

So all we do is hook up the two wheel like the pervious four, add a sprocket and we are good to go? Or is there something fancy to do? (No one is currently at the robot so I cannot check myself and we will be doing this immediately tomorrow morning).

Is there extra sprockets in the KOP?

Edit: I am not on the build team so some of my questions might be silly, but they didn't do it so I am switch I am helping out since I have nothing else to do

Nope, nothing fancy. The bad news is that only 4 sprockets came in the KOP; for a short-term solution, move the wheels on the light end of the robot to the middle and have the wheels at that end unpowered until you can get sprockets in. (The KOP sprockets can be found at http://www.andymark.com/product-p/am-0737.htm for $9+shipping; I'd get 4 so you can have a shorter chain run to the front wheel.)

Ah, so we split our long chain into two medium chains for each side.

Is there absolutely no temporary solution for a four wheel drive so we can still do decent at the scrimmage we are going to tomorrow?

Yep, move the powered wheel to the center and leave the light end unpowered.

Or, as I noted earlier, wrap zipties all around the rim of the light-end wheels. That's one of the oldest tricks in the book, and it works as a temporary measure. (Or a permanent one, in some cases.)

When I say "light end", often robots (particularly 6WD robots) will have one end heavier than the other, which means the CG is slightly to one end or the other. The wheels where the CG is not tend to carry less weight, so modifying them is less detrimental to traction.

Thanks for the help, we will try the zip tie thing tomorrow and then as a last resort unpowered six wheel drive.
