Does anyone else NOT use a long arm to place a tetra on top of the Goal?
 
I'm just curious: All the pictures I'm seeing are of a long arm which is used to place the tetra directly on top of the goal. My team's not doing that (and unfortunatly I don't have any pictures), we are sortof pushing it over the goal so that it falls into place. See you at the Duluth competition!

Team 1559 is using an arm thats only about 36 inches long. We have an elevator type lifting mechanism. It is made specifically for the autoloading station.

Cyber Blue uses a lifting mechanism and a rather short arm to put tetras ontop of the goal. :]

A rookie team that came to our practice, 1688, was a very impressive fast little bot with a flipping mechanism that tossed the tetra into the goal.

Team 85 has a short arm and 2 loaders that work just like a candy machine! We will see you at GLR. You can see at picture in the robot showcase.

Take care

We have a tall bot with a short arm, that helps with the complexity and the weight.

we have an elevator system and then a turreting arm that can hold two tetras at a time....http://www.chiefdelphi.com/forums/pi...&quiet=Verbose

though we do have a very large arm, technically it is simply a lift. All of the three arms are connected via a chain linkage and reduction off of a single van-door motor. This causes the third arm/end effector to stay level with the ground at all times; perfectly and constantly in line with the front of the robot.

Ours takes tetras from the human player and with one air cylinder flips them on the goal.

We have a cool accordion kind of thing. It has an angled panel with a flap to hold the tetra on, a cylinder type attachment picks up the tetra, and puts it on the goal. =) It's funky. If you have absolutely no idea what I'm talking about, here's a picture of Moonraker.
:D
