The Hacker News hive mind is real! I was just reading about JSD the other day after reading about KL divergence...seems like a nifty measurement device for things like sim-to-real …

if you liked this and the history of the industry, "The Prize" is a fantastic read!

No mention of New Jersey, sacrilege.

same! I did some river/lake sailing as a kid on the East Coast but now the urge is calling to me! I remember the "righting the boat" test being the scariest/most fun part of the ex…

I've been super interested in sailing since moving to San Francisco and running around the marinas/Embarcadero. Did some digging and found a sailing school that I haven't asked abo…

mold making is also pretty complicated -- anything in the 1,000-1M parts produced will _probably_ be an aluminum mold (cheaper than steel) but they're still heavy and large to keep…

This scratches a corner of my brain I didn't know I had. It's the start of the month and I'm writing investor updates, and seeing an author who...wants to treat writing a book like…

Bucket Robotics is building AI-powered defect detection for manufacturing. Every year, billions of dollars in parts are scrapped due to undetected defects. We use CAD-based synthet…

I fed TRELLIS an image of the left side of my Vespa, and it correctly (mostly) added exhaust on the other side. Super, super cool to see -- really hyped for what this means for 3D …

Half of college I'd take the Crescent from Philadelphia to Atlanta, then back at the end. It was great -- you could bring on as much as you could carry (I brought a beanbag chair m…

That's another very, very interesting case we thought about tackling. That sounds like something that's ripe for transformer-based vision models to keep the overall size of the mod…

Dude yes exactly!! It's so incredibly frustrating when you're past final assembly of some system, and only then do you see a defect that requires a teardown! You touched upon a rea…

Injection molding houses are heavily concentrated in LCOL areas -- but it's a massive market, so, so much of modern materials are plastic that there's a lot that's done in the US/C…

LLMs like GPT-4o have some pretty impressive image performance. It can actually pick up some of the more obvious defects on our buckets (Steph tested it out just now). Two problems…

> Nice! I have so many questions.. How stable is the injection molding process once it's fully proven out, up and running? Is it a bathtub curve shape, do defects keep randomly pop…

I'll answer in reverse order. Making synthetic data from a 3D model is really nothing too special - it's just a tiny subset of what video game engine does. But there's one extra st…

Regarding pricing: we we charge at a per-model basis -- so the workflow when you're ready to retool your line, send us the CAD and we'll send you the defect detector model and the …

You nailed it - when the part comes out of the mold, it slides down a chute onto a conveyor belt. From here, the arms themselves change depending on the supplier (Kuka/Fanuc/Univer…
