Nice!!

is the wooden plank considered outside chassis

I love our robot and all but the thing that sticks out the most to me in this picture is the tipped over stool. Why is it tipped over?

haha Thanks!!!=D The wooden plank was just a quick way for us to mount a battery because I wanted to drive before the night was over. We decided that one bolt, 2 clamps and a bunch of zip-ties was ok to hold our battery on for that session.... We were amazed that it stayed on

You know how the shop is....

I don't mean to pick knits, but can we use kitbot frames from the previous years? Are they still available as COTS parts?

if you are concerned I would ask the Q&A but since it is still a commercially available product I would say yes it meets COTS requirements. http://www.ifirobotics.com/kitbot.shtml


just FYI the above picture is of the new andymark chassis in the "wide body" setup.

There is a thread which directly answers this question: http://www.chiefdelphi.com/forums/sh...e+COTS+le gal

IFI still has the old kitbot frame on their website, so it could be purchased and used this year. I'd suggest any team doing so have a receipt available for inspectors.

[MattB703]

Thanks, I didn't realize they were still for sale. That clears it up.

[AustinDpOwers89]

doesn't your front end violate the bumper rules?

<R08>
A. BUMPERS must be built in segments, with a minimum length of six inches, and a maximum length that does not exceed the maximum horizontal dimension of the ROBOT

L. The BUMPERS must be fixed to the BUMPER PERIMETER.

M. The entire length of the BUMPER backing must be supported by the structure/frame of the ROBOT (i.e. the backing material must not be in “free space” between or beyond attachment points) (see Figure 8 – 3).

I think it does violate the bumper rules. Which is ridiculous. The GDC needs to clear up the intent of their bumper rules ASAP. Your team, and mine, and dozens of others, have frames that may or may not be illegal, and all we can do is sit and wait for the GDC to make their ruling.

I don't see this frame as violating the rules as long as the end caps are 6" long. Why would you think that it was illegal?
FYI: Check team update 2. They have answered many bumper questions with this update.

[Jared Russell]

It all depends on whether the front ends of their frame are at least 6" wide, so I was a bit hasty to call it illegal. It's hard to say based on the photo. As long as they are, you are right, they are legal.

[Vikesrock]

The front ends of the "wheel modules" of the kit chassis are 6.25 inches wide when constructed as as shown according to my CAD model of a VERY similar chassis we are going to start constructing today.

[AustinDpOwers89]

well if they're 6.25'' then yeah, they're fine. i was just expressing my concern incase they weren't and if 816 wasn't entirely aware of the crappy new bumper rules.

[thefro526]

Thanks for the concern on the bumper rules. The front sections are slightly more than 6 inches wide which will allow up to run a legal bumper on either side.

Btw, for anyone building a wide base from the kitbot chassis this year, we found that if you build it per AndyMark's instruction you'll have and ugly open corner on one end. We fixed this by cutting one side rail 1 inch longer than the others.
