      there arent any magical sensors, they probably are just cameras with a lot of trained images with that little ball. so u should be able to make them with any camera and AI software. you cant even pump up the resolution cause they would slow the algorithms so the only real difference they can have is the light rings

  • unfa🇺🇦

    The fact that your wife is able to hit such a tiny target flying so fast is just insane. And the amount of engineering that was required to emulate that, just shows how amazing her skills are. Though I must say - when the autobow finally hit a moving target - it felt really great to watch, after witnessing your struggle.

    As I watched this, I almost fell out of my chair cracking up, and I immediately subscribed. As an old, former software engineer, who provided well for his family for 35 years as an embedded software engineer at Bell Labs and other fascinating places; and, whom his friends and family told him, would never get an interesting job pursuing super boring degrees in mathematics, I love how you encourage young people with wit, humor, and marvelous inventions. At the end of my career I decided to teach Adult Ed to those needing a high school diploma or GED and it was a wonderful, life affirming experience for me. Most of my jokes didn’t land as well as yours; however, it was always wonderful to see students eyes light up in their awakening to science, math, and writing; and see many head off in a positive vector. I remember I got so excited when the Arduino and Raspberry PIs came out, and nobody could seemingly understand why. After about ten cool inventions for my grandkids I think they all get it. Look forward to watching your videos.

    As an archer myself, I will tell you that you will get more accuracy out of that compound bow with a drop away rest than the force inducing whisker biscuit. Try that first. In addition, even with a compound bow you cannot get away from the archer's paradox. Spine to tip weight to bow draw weight absolutely matters. Hit me up if you want to discuss - software engineer who has a complete obsession with archery. Love the vids.

      @MyLonewolf25 Substantially maybe not. He’s trying to hit a Lego Apple (size of an aspirin) consistently. I’m not aware of any tournament compound bow archers that use whisker biscuits. They introduce forces that make your shooting less deterministic.

      Per Westermark

      @Radix 53 Lots of engineers can do a self-aiming robot. The main question is how long it takes and how expensive. Engineering is on one hand a question of iterations, where a better engineer has a faster convergence on the iterations. And on the other hand, it's a question of ability to think outside the box. Which means either magnificent failures. Or big gains by doing something cheaper or smaller or faster than when going the traditional way. Anyway - it's silly with thread debates arguing if person x can or can not do something similar. It isn't that far from "mu dad has a bigger..."

    If you had used a bow with a draw length that suited you, you could've drawn it back further and not have been punching yourself. Also, maybe a beeper to indicate when it would release? Dunno how hard that'd be to incorporate, though.

      I need no channel youtube!

      @Kommentator Correct. The problem here is made up of the tracking, the ballistic compuiter program, and the automatically aimig system (and the harness for it, which to me looks like an off the shelf camera stabilizer). And the tracking was indeed off the shelf.

    • Kommentator

      @I need no channel youtube! All true, but only an issue when trying to turn this into a product which can be used in the real world. My point isn't that this would be easy or hard, but that this is a mostly unrelated problem. The bow shown in this video doesn't care how the tracking is done. The cool part is the auto-aim. Imagine combining this with @JoergSprave 's auto legolas. Actually Joerg tried to convince @StuffMadeHere to do this, but he declined (for good reason).

    • I need no channel youtube!
      I need no channel youtube!

      @Kommentator Tracking is indeed the hard, and as yet unsolved part of this challange, which is why you dont see smartgums irl. Target tracking is impossible to implement on an individual scale in a practical manner. It is however possible with large infrared sensors, and is in fact in common use in most vehicle based weapons, and has been for years.

    • I need no channel youtube!
      I need no channel youtube!

      @Kommentator Object recognition is incredibly computationally taxing, albiet finally possible via AI. There is good reason real word tracking systems either use something very high contrast (the balls in this example, massive heat signitures, radar returns in emlty air or sonar in ocean etc.) Or they require the target to be manually designated via a specialised marker, usually a laser.

    • I need no channel youtube!
      I need no channel youtube!

      This is basically a ballistics compuiter. Things like this were already on warships in ww1. Granted, those ususally abstracted the problem down to two dimenaions, but they were also mechanical, and had to track via viaual instruments and manual coordinage input.
