Team 469's Robot for 2006 pic 2

Here is a picture I took while we were practicing on some morning this past weekend (not sure which one...it's all a blur)...

Some specifics:

- 4 motor, 3 speed drive
- 180 degree rotating turret which can be controlled by the camera (including exit angle)
- dual wheel shooting mechanism with velocity and spin control
- 30+ ball helix storage system
- floor loading cabable
- center goal tracking and scoring (2 bps)
- corner goal scoring capable
- expansion (not totally shown) for easier human loading

Here are some large videos I took with my digital camera when we were debugging the transistion from the helix to the conveyor system.

what sort of equipment did you use to make the helix?
we were going to use some emt conduit tubing on our robot and we had a hard time making a regular circle

also I think that loading from the floor through the center of the helix is a very clever idear

Yet another spiral.

We used a central aluminum pipe that holds 60 aluminum rods in the formation of a spiral staircase. It's a bit heavy, but we can make it with less machining and stuff.

I really love your hopper.. looks a bit heavy, but it wins for the ammount of balls it can hold

I spent a little bit of time with 469 a day or two before ship, and that hopper is money! Very light, very sturdy, and great capacity. I can see some Industrial Design in this hopper.

Oddly enough, the helix, with ball-stop mechanism, weighs 4.69 lbs.

Thanks Rich.

In fact, the helix storage weighs less than 5 pounds complete. Completely made from 0.035" wall aluminum tube. Thanks for the comments.

We are anxious for GLR.

Wow, by the look of that robot, I'd say you were 15 pounds over. But looks can be deceiving I guess.

The entire frame is made of aluminum square tubing. That stuff is hella light.

Actually, a lot of it is 1/16" thick angle...

So it's hella lighter?!?
