Inventor Tetra Connector

[team222badbrad]

Thanks!!!!

The file works great.

I have included a picture of the tetra using your piece.

It seems that you are all bending it on one line. In reality the clovers have a smooth curve. Have you thought about drawing the curve as a surface inb AutoCAD and importing it? This might be more than you want though.

It does not matter how they look, just as long as they allow Inventor to make constraints that do not crash!

I'm not sure what you're making these models for, perhaps the animation? Anyways, if they are supposed to look like the tetras that will be on the field, there will be end caps on the pipe that the connectors connect to (team222badbrad - you just connected the connector directly to a pipe)

Also, I met with Dave Lavery just the other day to discuss what materials and coloring will be on the field, and he told me the pipes for the tetras will be aluminum with a matte finish, while the end pieces will be a similar shade metal, but more glossy.

[team222badbrad]

Yes I know they need end caps, but I do not have dimensions for those...

If anyone has those would you please share?

I am personally not modeling them for anything in particular. I may eventually build a whole field just for something to do.

I just build the model shown in this thread to see if the tetra pieces part on here, actually allowed me to make constraints in Inventor.

Could anyone post a full model of a tetra? I'm not the best with inventor, but I want one that I can look at and spin around and such with.

If you do post a file can you also post a .STP (STEP) file so that I can import it into SolidWorks.

thanks a million guys, we have completed the side goals, but are still in a dead end when it comes to the centre goal, as we do not have any drawings of the centre couplet or the base couplet.

I will put up a drawing of the goal if we get how to make it, hopefully by tomorrow
In the meantime, any help on how to make them will be greatly appreciated

[ajlapp]

please do post the completed tetra.........better to share our resources than try to build one from scratch.

I tried opening that one that was posted, but when it opened, I could not see the part. Mousing over the model parameters, I could see the outline, but how do i make it visable?

I'm using Inventor 8 Pro

[team222badbrad]

You have to open the file.

Once it is open drag the little red circle with a white X named END OF PART to the last place on the list.

This is located in the browser bar. If you do not see the red circle click view, then toolbars and then click on browser bar.

I will try to post the tetra without the end caps...

we are trying to create a centre goal to test our robot design, but we are having problems with the base couplet (flat surface) and the middle couplet (four attachments)
has anyone been able to create that? FIRST did not provide the design in their manual
help on making them would be greatly appreciated

We'll post it on our website as soon as we have it (the site) set up for it - probably in a couple of days. The assembly is way to large a file to post as an attachment - the connector alone just made it under the 100K limit.
