Re: pic: Team #8's Tube Interface

Interesting design!

Have you checked the air pressure in the ring? do you know what it is supposed to be? (I dont' really know myself)

We noticed a large difference in handing the rings when inflating them from about one psi (as yours appears to be) to over two psi.

FIRST says that the tube should be ~9.5" in diameter when fully inflated, but we have seen that it is much harder to control the tube when it is only slightly deflated. Because this is just a prototype, we will try to figure out all that other stuff when we get everything working. This was just a good proof of concept.

That looks vaguely familiar...

Re: pic: Team #8's Tube Interface

I'm curious what the procedure for grasping tubes looks like. Specifically, if a tube is laying flat along the floor, is this capable of capturing it?

Re: pic: Team #8's Tube Interface

This entire assembly will be attached to an arm, there will also be two large wheels on the end of the two plates (where the holes are) which will "Suck" or "Blow" the tubes. the way the arm will be set up, it will allow us to pick tubes up in any position. We also have a way of getting them off the spider legs.

Re: pic: Team #8's Tube Interface

So I log onto chiefdelphi to see how some teams are progressing... Maybe see if any teams have any good pictures up, and the first one I see is of he grabber my old team just made... what fun...

Laser cutters are quite handy for rapid prototyping

Yes laser cutter are, and I wish we had one...
nice prototype there, like the idea. We will see how effective it will be, i only worry about the pressure consistency of the tubes.

Re: pic: Team #8's Tube Interface

I assume with those two wheels you could also rotate the tube in your grabber by running them in opposite directions?

I must say it's brave of you to be putting up a prototype for widespread speculation. And on that note, have you thought about interference from the huge flange? Or do these two wheels mean to sort of project the tube a short distance?

How easily will that pick up the game pieces?
