Hope you like, guys!
Salutes from The Brazilian Machine!!!

That looks really cool, how much range can you get out of it?

Re: #383 ball launcher system teaser
 

I want to see this thing working. those arn't even mini-cims so I cant imagine you get a very good shot out of it

Re: #383 ball launcher system teaser
 

RS- 775s work pretty darn well for shooters. I think you'd be very surprised.

Re: #383 ball launcher system teaser
 

A "good" shot in this game might not necessarily be a distance shot anyway. But I also wouldn't be surprised to see these wheels launch it pretty far.

I love it, and look forward to seeing it in action!

Re: #383 ball launcher system teaser
 

we are launching up to 16 feet, but he is actually very reliable at 10 feet. the principal is not the engine, which is very good, but the pressure and the area of contact on the ball ...

also, there is a chance of a video for today, but tomorrow is for sure!

Re: #383 ball launcher system teaser
 

We used rs-775s last year on our shooter with a 4:1 gear reduction. This brought us down to about the same rpm as a CIM but with more torque. We could even do full-court shots with them. They can pack a punch if used correctly.

Re: #383 ball launcher system teaser
 

OP - Very cool, haven't seen anything like it on CD yet this year. I would love to see a video of it working!

You should read up on motor power ratings before making such statements/assumptions.

Re: #383 ball launcher system teaser
 

RS775-18 = 273W
MiniCIM = 229W

A 775 can provide more power than a MiniCIM. I'm betting they are shooting just fine.

Re: #383 ball launcher system teaser
 

We are finishing the mechanical parts from the robot, probably 3 or 4 more hours and we will be ready to record some shootings and post here...

here's a picture from the work up to now...

Re: #383 ball launcher system teaser
 

What's that material on the rollers?

Re: #383 ball launcher system teaser
 

By the rollers i suppose you are referring to the "brownish" pipes???
they are 40mm (+- 1.57 in) PVC water pipes...

Re: #383 ball launcher system teaser
 

Looks powerful. Nice.

Re: #383 ball launcher system teaser
 

Here I thought our puncher was a monster! That thing looks spectacular. My compliments to whoever was involved in the assembly. Yet, I cannot clearly see any form of ball intake. Does your design make you reliant on your partners to hand the ball to you before shooting?

Re: #383 ball launcher system teaser
 

Hello guys,

here comes the video!!!!!!

Re: #383 ball launcher system teaser
 

Does that intake work with bumpers on the robot?

Re: #383 ball launcher system teaser
 

I was thinking the same thing. That dip on the intake side looks lower than 7 in off the ground.

Re: #383 ball launcher system teaser
 

Nice to see another solid machine from our pals from down south. :)

Re: #383 ball launcher system teaser
 

That is incredible! that shoots really powerful.

Re: #383 ball launcher system teaser
 

Re: #383 ball launcher system teaser
 

nice to see something different! awesome work

Re: #383 ball launcher system teaser
 

How much does the compression of a ball affect the shot? Have you tried with balls blown up to different sizes yet?

Re: #383 ball launcher system teaser
 

Hi,

I can't tell you exactly how much pressure there is, but, as you can see, in the video there are 2 balls (red and Blue), and they got a big pressure difference between them.

We tested many times the difference on the range with the 2 balls, but there is a limit distance in which it's irrelevant.

Re: #383 ball launcher system teaser
 

Awesome concept, even more impressive packaging.
It's a shame we won't be seeing you guys traveling up here to New England anymore.
Good luck this season.

Re: #383 ball launcher system teaser
 

So cool. My favorite robot so far!

Re: #383 ball launcher system teaser
 

New video from test #3:

http://www.youtube.com/watch?v=32cyE4vHi_A

4 shots:
* #1 - close range: 7'5"
* #2 - medium range: 18'7"
* #3 - long range: 24'6"
* #4 - Truss

(sorry for the uncut video)

Re: #383 ball launcher system teaser
 

Putting backspin on that truss shot is really clever and something I doubt most shooter could do. Was it intentionally designed to keep the ball from rolling forward in case of a missed catch as well?

Re: #383 ball launcher system teaser
 

Thakns a lot! And, yes it is!:cool:

Re: #383 ball launcher system teaser
 

Looks great guys, I love the variability that the wheels allow you to build into the shots.

Re: #383 ball launcher system teaser
 

Thanks!!!

Also, tomorrow, by the midnight here in Brazil (22:00 EST), i will create a new thread for the robot 100% done, with a video in better quality, but i will keep uploading robot photos for today and tomorrow here!

Re: #383 ball launcher system teaser
 

Do the double wheels per motor provide a significant advantage over just single wheels?

#383 ball launcher system teaser
 

Yes, they provide more pressure making the shot more precise.

Re: #383 ball launcher system teaser
 

Jeser and I from 1772 were just talking about this, the Brazilians are coming to Orlando looking to win it all I see.
