[Ri3D] Team Indiana Presents: Veronica

[Jacob Paikoff]

Great looking robot, I would expect nothing less from Team Indiana.

Why did you guys decide not to scale?

[Mr. B]

What do you mean by "Googly eyes for +1 vision tracking."
Great Job, Thanks

[nxtmonkeys]

Amazing robot.

It can do almost everything...
I want one.

Can you make it jump-hang?

[waialua359]

2 Questions that come to mind.
1. What prevents the ball from shooting out of the flywheel once its in the robot? Cant really tell what kind of release mechanisms it has.
2. With a tall 4 1/2 foot robot in front of the robot without touching it (in case its in the safe zone), can it shoot over it or will it be blocked?

Those aren't your everyday googly eyes, those are advanced googly eyes. The robot is actually partially alive

I think it's just human intuition.

What are the specs for the shooter?

There is a holding position where the ball rests before reaching the wheels of the shooter.

Okay now this is my favorite Ri3D robot of the year. Great job packaging everything and doing it all but the hang in 3 days. Awesome!

For a brief moment in 0:20 to 0:21, you can see the roller holding the ball against a blue plate.

Not that Betsy's answer wasn't sufficient, but I'd like to add a "little" bit more detail.

We do not have a release mechanism currently. It's more based driver instinct to not drive the ball into the shooter wheel at the moment. We experimented with a current sensor to try and find a difference in intake current, but had no luck (and little patience). A beam-break sensor would be ideal, but that's for later addition.

Our shooting sweet spot is right in front of the tower, with wheels touching the BATTER (base of the tower). Ideally, we'd beat the defense to the spot and take away the chance of the defense blocking our shot. The video of us shooting from farther away was taken during prototyping. An issue we saw with shooting from a distance was the difference in compression between a fresh boulder and a used boulder, which affected shot performance.

Great job!! Really nice package, and I like that it's also a homage to our dear departed Dozer.

It looks like the arm gets hung up on the drawbridge trying to side down. Would something simple (like a tennis ball) on the end work?

Can you give some examples of how the wear affected shot performance? How much wear are we talking about?
That makes me nervous. 5254 and 20 haven't tested with worn balls yet because both teams have only one ball right now.

If I was to guess, it was somewhere around 50 shots. We dialed in the prototype shooter until it worked with one ball, then we tried another ball, which flew completely over the goal.

The foam directly under the skin "crumples" slightly after many shots. You can feel the difference when you squish them by hand.

What was the length of each pieces of the double jointed arm?

I don't remember the exact number, but it's pretty easy to calculate--subtract the height of your mounting location from the height of the drawbridge, then divide by 2 and add a few inches to account for the joint and a bit of extra space for the drawbridge grab.
