Re: pic: Effective height of the Tunnel

After seeing this, did you (or anyone) happen to check the actual width of the tunnel?

Re: pic: Effective height of the Tunnel

Is the tunnel really 36in. wide or 44?

Re: pic: Effective height of the Tunnel

I'm looking at the diagrams provided in the manual attachments and it lists the inner wall as being 16.5". Is this a discrepancy in the manual or in your measurements? Or am I just completely off-base here?

I don't know; the tape measure wasn't perfectly straight, but it was fairly close. A question for Q&A maybe?

Again, I wasn't the one taking the measurement and I have no idea who it was, but I would be interested if they had other ideas or took other measurements (of the other tunnel, say. This one may have been assembled wrong).

my guess is they will revise the drawings. the rules say 18, changing it to 17.5 is not a huge deal but taking it to 16.5 is a big change. So my guess is that will change.

Re: pic: Effective height of the Tunnel

yeah, I'd like to know the width of the tunnel as well. as in- when going straight through the tunnel- how much room does the robot have from side to side?

The inside wall is 16.5, true, but it sits onto of aluminum piece that is 1.5" tall. In addition to this, there's some plywood that subtracts from the height, and some aluminum plate. All said and done, the CAD model (that I constructed from official FIRST plans) says 17.75 tall.

By the way, if someone wants a CAD of the center field pieces (tower, tunnel, bumps) give me a PM and I'll email them to you. (Solidworks 09)

Edit: You can also grab them from here.
