Dad's Design

[Tanner]

Here's what I have of Dad's Design so far in CAD. I love 8020, cause it is so easy to CAD.

I allowed 4in b/w the inside/outside of the chassis to allow room for sprockets/chains/stuff. Dad thinks this can be smaller, but if so I can make it smaller. The kicker has to be made smaller, but is now only 14in versus 22in. That's what I get for the 4in of space I took away. It should still be accurate though as far as hitting the ball.

Later, when I get the wheels on and a few other things, I'll design a floor and soccer ball so we can see how it contacts it at example angles and things.

Um, yeah.

Thoughts?

Good Stuff, Really Good stuff.

Just a couple of questions.

1. I'm guessing this chassis will be compliant with your chassis layout?
2. Which part of the frame do the bumpers mount onto?
3. Do you think we can get away with mounting the kicker lower? Mounting it lower will make the actual kicking face smaller, but I really don't like how right now it takes up a lot of space in the under belly.

That's definitely good work. Where you have the kicker, might I recommend some Diamond plating? It's strong, and flexible at the same time. Or maybe even some plexi.

From here, could you basically take this and cut it down and add some of the mods that you and I talked about? Maybe move the tubing into the inside of the kicker, like that one vid. and then move the cocking mechanism to behind the kicker? Save as v2 or something.

It could be, though I'm not doing that at the moment. I want to figure out the top-side and then do the bottom.

2. Which part of the frame do the bumpers mount onto?

Haven't gotten there yet, but the normal part where they would I guess.

Lower? Like lower in the drivetrain? I can't make it any lower otherwise, it'd touch the ground.

Dad said the only point of contact is pretty much the end, so I put a "toe" there and just supported the area around the axel. I guess I should put something around the curved part of the kicker to help it.

Tubing to the inside of the kicker and cocking mechanism behind the kicker? Hm?

The only problem I kind of have at the moment is the placement of the kicker as far as forward/back on the robot and a bit up and down. The forward/back movement is limited by the length of the arm part of the kicker (i.e. the part that latched onto the gate release). If I make it shorter, ergo, allowing me to move it forward more, we'd need stronger surgical tubing. And vice-versa.

Ok. I'm done CADDing for tonight.

I added a motor and a roller in the back. Dad was asking how we could tension the tubing for different strengths and I said we just do it by wrapping it around a large pulley thing which would increase the tension. It'd have to be a strong motor though.

As for cocking the device, up in front there'd be a linear actuator that is pulling on a string. Through a series of pulleys, the string pulls on the "arms" of the kicker until it is cocked forward. Then using some sort of pneumatic, we release it.

I like it. Simple.

Well, you'd have to reduce the size of the kicker to make it work, but that's the idea. The kicker system is HUGE right now.

Well, place the kicker in a manner so that when the ball is all the way in the 3", the kicker kicks it with a curve, and when it's saying 1" into the system, the kicker kicks it almost straight, but still a little up.

Yeah, it is quite big. There's only around 10in of space left on the drivetrain practically.

Team 987? Incomplete thought?

Hm. True. I'll see if I can do that, though adjusting the little feet I have for the ribs of the kicker is really a pain (they're kinda made up as they are now). I think it is made up of circles, but I'm not sure how much I can do. I'll see.

The robot that kicked the ball so hard it knocked down a clock.

The strength of their kick is provided by high tension bands and REALLY unnecessary. If we can take our surgical tubing and put it in a similar fashion, we can save a lot of space.

I can't find their bands in the video. I see a lot of black cord that could be a band, but don't see how they are attaching it.

-Tanner

Yep, the black cords are the bands. They have one end attached to the lower part of the frame, and then one end attached to the actual kicker. When the kicker pulls back, the bands pull from the bottom, and when it's released, they shoot forward.
