I wasn't totally satisfied with my previous basketball hoop so I made another try at the problem. This time with robots and computer vision! I designed and build this hoop from the ground up with the goal of tracking the ball and directing it into the hoop by tilting the backboard. It works pretty well. My old solid state hoop is old news. Long live our robot overlords.
I wonder what V3 will look like...

  • Stefan Shapiro
    Stefan Shapiro

    When you're calculating the trajectory you wait until you have mathematical certainty on the final location and make a single move there. Did you consider beginning the move earlier, based on inaccurate data, then subsequently fine tuning the move? It seems like that could result in slower and smoother motion, though as we both know things aren't always as we guess.

  • Nigel Higgs
    Nigel Higgs

    You have a really creative way of dealing with the ball scenario for your software, most people would just attempt to brute force the identification problem by essentially creating a deep learning model with souped up GPU's to improve inference time, simple data structures along with math is a beautiful way to approach this.

      Ole Ravn Hagland

      @TheVoitel what

    • TheVoitel

      Shouldn’t be that much LinAlg, should be mostly Algebra/Numeric Mathematics. The basic idea should be: X(t) = X0 + V0 t + A/2 t² where X is the coordinate of the ball in space, V0 is its speed vector at time 0 and A is the gravitational acceleration. Then we want to solve for a t1 and an affine reflection R at X(t) of V(t) so that X'(t) = X(t1) + RV(t1) t + A/2 t² hits a specific point P. The reflection R can be parametrised by a normal vector or two angles. We can then separate the problem: If we only look at the angle phi in the x,y-Plane then for each t1 this is a trivial linear problem (and given t1 and phi whe can calculate t so that X'(t)=P if such a t exists). If we look at the height angle theta we then have to solve X'(t1, phi, t)(theta) = P, which involves inverting trigonometric functions (but can be avoided by doing the same with normal vector). (All of this can be done symbolic). So we only need to calculate t1 so that X'(t1, phi(t1), t(t1), theta(t1)) = P has such solutions for phi, theta and that X(t1) close to the current position of the board and phi(t1), theta(t1) close to the current angle of the board. Add some constraints and we basically get a nonlinear optimisation problem.

If you could engineer a time machine that would be great. Also I greatly appreciate the balance of practical knowledge/laughs in your videos.

    Love the concept of a can't miss hoop, and appreciate the engineering and programming that went into this version as well as the others. Not sure if someone has suggested this already, but could you get similar results with a regulation backboard that doesn't tilt in either direction but instead is made up of a grid of small solenoids? You could use all of the same ball tracking you've devised to determine where on the backboard the ball will hit and then rapidly actuate a solenoid or solenoids to redirect the shot in (might not even need to be more than 1 cm of throw for any solenoid). There would be several advantages to this approach if it could be made to work. First, with the solenoids mounted behind the backboard and flush with the surface, unless someone looked carefully they wouldn't notice it was a non-standard hoop (i.e. they wouldn't immediately know you were cheating). Second, solenoids are relatively simple bullet proof components that might be more robust. Third, there might be a way to address the very extreme, line drive shot with this approach. Just a thought. Keep up the good work

    This is awesome! Do more videos like this. I'm an engineer major and am constantly looking for practical ways to use math because I believe that there are far more limitations related to it than what actually could be done.

    Great video. I wonder, if to improve on response time. Could you define a secondary backboard position that would make the final calculated position closer and faster to achieve then from your initial start position. In other words, once ball release is realized it immediately moves from start position to secondary position and once calculated, to final position.

  • quaji1

    Very cool. One possible improvement idea: You said that you wait til the last millisecond to move the board, and that you have timing problems. You might consider moving the board sooner towards a "best current guess" and then constantly refine the position as more data comes in. This might also look cooler as the board will seem to just smoothly move into place instead of the sudden jolt it has now.

    • mike s
      mike s

      ​@haphazard1342 definitely. This problem in particular is probably linear so I doubt you'd ever even find a bad local min. I guess I wanted to point out that in general, making those assumptions about the optimization without checking first that the problem is linear may lead to puzzling results.

    • haphazard1342

      mike s That's true, but he appears to already have enough logic and data to work around that: there are a couple parameters he could use for confidence before starting the open loop/continuous optimization, such as the current time to strike estimate or a ball landing position confidence interval size. The goal here is to start moving as early as possible, because most of the time that's going to get you closer at the last second final move than just waiting still. Also, the rate of movement vs the operating window doesn't appear to be too small. In other words: his backboard can move fast enough, and doesn't have too far to go, that it shouldn't ever run into the scenario you describe, even without the optimizations I mentioned.

    • Cyberguy42

      One option would be to move the board towards an early guess only once the uncertainty in the tracking estimate was below some threshold, that would reduce the likelihood of moving to a completely bad pose

  • Owen Kegg

  • temporary_name

    Awesome project! Isn't it possible to make early guesses? For example when we have 3 frames with maybe balls in them we guess the trajectory and if it comes anywhere near the system we adjust the board's position and then we refine as we get more data. Also, ranking potential solutions seems wasteful - why not just find the one that changes the current position the least?

    I'd like to see it run in the mode where it takes the other quadratic solution if it can. Pop the ball up and let it fall into the net :)

    7:08 you could simply use a faster microcontroller, like an stm32, it has 72mhz clock compared to the arduino mega 2560, wich is 16mhz, as the fastest arduino. And you can also program it with the arduino ide.

    Would it have been possible to have the hoop move continuously to the best estimate based on the current information during the flight of the ball, this might also make the problem of force easier

    I would hope there's a difference with high vs low barometric pressure or dry vs humid air (considering longer shots especially) because it would be cool to adjust for that.

    Your first shot- you throw the ball - POW - the backboard launches the ball through the roof and nearly into orbit - you sit in awe. The math was correct though... The ball does one full rotation around the earth- nothing but net.

      @AlleywayMurder when you throw the ball and it only touches the netting it is called a "splash" therefore the person is "wet"

      carl crooks when has wet been a basket ball term

      Imagine how fast the ball would have to be going to stay airborne

    Thanks for trying to show some of the logic and behind the scenes stuff in your videos that is clearly the most complicated part. Mind blowing stuff.

    Mark Rober: Spends three years creating automatic dart board. Stuff Made Here: Whips up an automatic backboard in a couple weeks... and it talks. (obviously no hate Mark is a legend respect)

      Mark usually gets help from other people, I think this guy did it all himself in such short time, not sure he is doing this full time or not but still impressive!

      Different challenges demand different solutions. Mark Rober's darts required extremely precise high speed tracking so he used a very expensive Vicon system. The basketball problem doesn't require the same tolerances. Let's hope these kinds of projects get more common.

      Seeing multiple engineers tackle the same problem entirely differently is proof we live in the Golden Era

      Daniel Halverson - the speed and tiny size of the dart makes it magnitudes harder to do it Mark’s way, but they’re really similar projects. The software here is arguably impressive for its simplicity - mark’s hardware is another level up from this but obviously took wayyyy longer to build up. I have more than a basic understanding of what’s going on but the computational limits that we’re seeing here are a huge factor.
