No need to lift your robot off the ground if down right.

Re: How are you pushing down bridge?
 

You might want to make sure it will count as one appendage, not two. There's been a lot of discussion about this here and on Q&A. It's my understanding that a two pronged thingy is considered two appendages (and thus illegal) unless it's all one contiguous piece outside of the frame perimeter, even as it deploys.

Re: How are you pushing down bridge?
 

It is one appendage leaving the perimeter that spits it into two equal-sized forks ... what on earth might contiguous mean in this context? It is solid, no articulating etc.

Re: How are you pushing down bridge?
 

I wonder if pictures would help?

I think it means that the part outside the frame perimeter is all connected together.

But I'm not as imaginative as the GDC....

Out being welded but will post the cad later

Re: How are you pushing down bridge?
 

I am also having a problem with "contiguous" (as mentioned in the G21 team update).

Our extension is sort of like a pair of salad tongs. One of the tongs is articulated. The two tongs do not contact each other directly, but they are both connected to one other piece. In other words, they cannot be deployed separately. They are both part of one mechanism that is deployed as a single unit. Is that contiguous?

Wups. I think this may be a better place for my question:

Re: How are you pushing down bridge?
 

Depends on where they connect. If they connect inside the frame then it is my understanding that it is not a contiguous appendage. However, if they fork outside of the frame, then they are considered contiguous.

Re: How are you pushing down bridge?
 

Look OK? And what if we add a little wheel on each fork?

Re: How are you pushing down bridge?
 

::rtm:: Rule posting to follow:

Emphasis mine. From the picture, it would appear that it is contiguous within the frame, and the two forks of the appendage cross at two separate points of your frame. So, I'm not sure, but I do not believe this would qualify as a contiguous appendage.

Re: How are you pushing down bridge?
 

Hey - thanks for looking at it. We sure appreciate the advice. It is hard to tell from this rendering but the cross piece is outside the frame when extended. It is is roughly (vertically) over the edge of the bumpers. The frame is all 1x1 Al extrusion - see it running behind the rendered bumpers?

TIA

Re: How are you pushing down bridge?
 

Very brief violations of the contiguity requirement as a single appendage is being extended or retracted will not be penalized.



yeah.

Re: How are you pushing down bridge?
 

So use pneumatics to actuate your appendage :)

Re: How are you pushing down bridge?
 

Looks a lot like what we have. I guess now it depends on the definition of "very brief," how quickly the mechanism deploys, and probably on which inspector you get on game day.

I think the wheels are much less of a concern than the 2 prongs of the fork.
