Back when I was brainstorming the first moving basketball hoop it was immediately clear that a hoop that moved in 3D was inevitable. Aside from being the logical conclusion of a moving hoop, it's also awesome. 

I mention in the video that this hoop is capable of much higher speeds. I couldn't hit those speeds due to a number of limitations with the actuators, cables, electronics and software that kept me from pushing it any faster. It was hard, but I successfully held off fixing them until I could get the video done. 

But now that's out of the way, I'm going back in and trying to make it go way faster. My main objective is getting it to do a double (or triple??) score from a single throw. I think it would move so fast it would just be mind boggling to see. If I can get that working I'll probably make another video about it (Hoop V4 part 2 :). Do you think that would be interesting?

If you have any ideas of other cool things that I could do with the system I'd love to hear them. Maybe they'll make it into the next video!

I hope you all enjoy this project and I appreciate your patience since it took me a long time to get this one done. Aside from the project taking a tonnnn of hours, I've also been doing a lot of manual labor for a workshop that I'm building which has made my pace slower than I would like. 

If you haven't seen it, you can check out the video here.

As always thank you so much for the support!

Would the action of the first/second/third goal slow the descent of the ball enough that you could keep it in an endless loop?

Mitchell Grenier

I wonder if it would be interesting to have the ball "unsink itself". So the ball goes in then hoop moves such that the ball goes through the hoop the other way.

Mitchell Grenier

In that same vein maybe he could bounce the ball back and forth between two different positions of the backboard

Dogburt Junior

That was in the video, the wife mode

Hey Shane! Awesome stuff, per usual. If I had to pick a few crazy things (and none of these may be feasible): 1) "Around the World", this would be absolutely wild, but if you could circle the whole hoop around the ball once before catching it. You'd probably need it to be at the top of the parabolic arc where the ball velocity is closest to 0. Any velocity is going to make that loop bigger and bigger. 2) "Around the World with a Kick". Same as above, but add a "bump" at the beginning that tips the ball straight up in the air. Bonus points for making the circle as big as possible. 3) "Bump, Set, Spike!" - Off the backboard at an angle, then straight up, then it can either sink a shot, or spike the ball into the ground (and maybe through the hoop? That's quite a sequence though. 4) "Back to Papa" - There's a move in street ball where the ball handler throws the ball from a distance hard against the backboard and it comes back to them. Maybe you could do the same? See if you could hit the ball back to the sender with any accuracy. 5) "Show-Off" - Take a shot, have the backboard hit it as hard as is possible across the plane, but have the hoop catch up to it and make a shot. It would likely involve swooping down underneath the ball and basically making the shot with the hoop at a ~90 degree angle (rim straight up at the ceiling) Apologies if these are outside the realm of possibility. Might be able to think of a few more, but here's some that came to mind.

Truly fun video and project. Thanks for doing all the heavy lifting and sharing that with us.

Gareth Farrington

If it did go a lot faster… could it play a human at ping pong? 🏓

Mitchell Grenier

In my mind I'd like to see the hoop literally turn upside down and have the ball go through it fully the other way though I do think the principal is close :)

Brent Foley

Amazing video! Hoop V4 part 2 sounds so cool! You astound me with the stuff you make happen.

EvySpaghetti

You should hire some interns to help with the grunt work involved with these large builds. We’re lucky you’re so dedicated to making cool stuff that you’ll do all that work yourself.

Since the backboard can zoom faster than the ball, make the backboard be an entire basketball team! "It's Backboard, dribbling the ball off its chest while floating 8 feet in the air! It passes the ball to...Backboard! Pass back to Backboard. Another pass. Going for a 3-pointer, it shoots....it scores!!!"

DenHundBeisstDerMan

This is a great idea, I was thinking of badminton or another lighter impact racket sport as the size of the machine lends itself to a court.

Andrew O'Toole

I actually think if you get it going fast enough, being able to have multiple balls in the air at once and have every single one made would be cool. Or, other ideas: - Mount a dart board on the backboard and do something similar with 5 people throwing darts all at once and making 5 bulls-eyes. - I think this system can actually be used to play pingpong or volleyball against. At the end of the day, it is a flat surface in 3D space that can move at incredible speeds to hit a ball. - In that thread, maybe a board that bounces a ball into a basket behind you! This feels like the most complex.

Forest Roberts

I loved this video and I think it is awesome that you are pushing to make it even faster. But I was wondering how accurate/smooth you could make it move slowly? Do the motors require the snappy movement? It seems like you would want to start approaching your target immediately, then adjust as it gained confidence in the intersection point. Could you get it stable enough to balance an inverted pendulum while doing other things?

Tyler Jensen

Like others said, being able to sink balls in the hoop as fast as someone is able to throw them would be so cool to see.

I agree catching / deflecting a large of balls thrown all at once would be impressive. Maybe dodgeball?

Other idea * glue a cup to the board and catch a large number of grapes in it * Glue bowl on board. Call it an "anything catcher". Throw large numbers of stuffed animals / fish / bizarre objects onto it. * make a giant floating polystyrene eyeball which flies around rapidly above your head and stares at you accusingly from various angles. ** Same, but with 3D printed model of wife's head. ** make head able to catch cowboy hats thrown in air

Badoiu Andrei

Would love to see kids with disabilities use it. To understand that everything is possible, that there's no limitation. Early morning thoughts...

Françoise Díaz

Awesome stuff! For a future iteration, I would like to see two adversarial devices going against each other. It wouldn't be basketball, maybe more like voleyball? Replacing the hoop with a paddle and trying to score points (or maybe even trying to get it into the opposite's robot's hoop). Probably too expensive and difficult to actually make, but that'd be cool to see. Like the next step in robot sports!

David Everlöf

Awesome suggestions here! Really looking forward possibly seeing them come to life! One small suggestion: while the board doesn't have any shoots to process maybe it could do something more "lively"? Like, making it seems as it is hoovering? It could basically have it's own life since it could nod or shake its head, etc.

Rick W

Can it carry a waste paper bin to catch any ideas you crumple up and throw away?

Trevor Flowers

Thinking of it as a generic 6dof actuator, it could be neat to change the backboard for a light and then make long exposure photos of it tracing 3D meshes, words,, vector drawings, etc.

Bill Schuller

Soccer goalie? Return the ball to a specific spot - maybe even straight back to the kicker?

Bill Schuller

Have it catch trash you throw at it in a bucket and then empty it into a trashcan.

No requirement for snappy movement. I just drove it as fast as I could. The initial intersection point estimate is very noisy, to the point that I might have to reverse direction on some motors which is slow to do. That's why I waited until I had quite a bit of data. You could probably balance an inverted pendulum. The software would be the hard part

stuffmadehere

that would be awesome. I might have to make a few more balls and try that

stuffmadehere

Volleyball is actually in my list! One of my friends suggested that - I Think it is mostly do-able - avoiding the net with the wires is the one tricky bit

stuffmadehere

That's a good idea that I'm probably going to steal

stuffmadehere

I had been thinking about doing something like that with the robot arm, but the scale of this is pretty interesting. Filming it with stereoscopic cameras might make for a really cool VR experience

stuffmadehere

haha I think it could. Tracking the crumpled paper is the hard part since my tracking system requires retro-reflective markers. I'd have to crumple it up then stick a marker on it before I throw it... I guess that adds a certain level of comedy to the whole thing

Gustav Linde

I love the idea of two of these robots without the hoops playing tennis or volleyball. Maybe there is another Youtuber out there that would like to challenge you? That would be inShane!

Gustav Linde

I see someone else made a similar suggestion I'll have to like it. They say great minds think alike and fools don't differ, still figuring out which one I am haha.

Gustav Linde

Make it swing the explosive bat! When you throw a baseball at it : )

Emily Washington

Or just a tennis rally "opponent" that will always return the ball to you or force you to run back and forth. Obviously I would prefer to see it playing Real Tennis, but lawn tennis is fine.

Emily Washington

Building a robot to catch and throw baseballs/tennis balls would be awesome. Bonus points for building a robot that can play fetch with the dog.

Jared

I second someone's suggestion about having two robots compete against each other in a sport like ping pong or something. Probably way too expensive but it's a cool idea. Definitely interested in seeing the 3D basketball hoop developed.

Nathan Myers

It would be fun to see it dribble the ball a couple of times and pop it back to the shooter, after; I guess it would have to get close to the floor, then. Just ducking under and bouncing the ball back where it came from would be fun by itself.

Jörg Thomsen

I think the idea of the basketball hoop has lost it's charmes. It seems more like an unhealthy obession... I strongly believe you should do something truly novel next and NOT return another repetition ... I find it rather boring.

stuffmadehere

I can see that point of view. Although I don't actually don't care about the hoop all that much. Its mostly an excuse to do things that I think are interesting. What's really exciting to me is improving my (quite rough) prototype for the the 6dof parallel cable actuated robot. That's why I'm trying to think about for more excuses to do that :)
