Re: [DIYbio] Opentrons OT-2 release

Last time I talked to one of the devs, they would like to get an OT port once they're more widespread. It's not here yet. 

And yep, that sounds about right for copyright situation. I'd rather write my own software and own it under MIT.

It appears that Antha itself is still FLOSS and gratis:

However, perhaps this GUI you mention is not FLOSS, and it's possible that they are not releasing device drivers. Because they are the copyright holders of Antha, they can do that even though for someone else it would be a GPL violation. :/

I'd still expect the OpenTrons Antha drivers to be open though, because it's OpenTrons.

(actually, if I remember correctly, you have to purchase actual Antha for support of running on the bots? It seemed like it was good for labs doing high throughput work but didn't want to have to think about running robots and developing code)

Antha is also pretty pricey per year, I think 4 times an OT cost?

That said, I met with some developers of Antha and I really like it. Their GUI is really great for management and wonderful for multifactorial optimization. Their data from optimizing GoldenGates was very impressive. It's a piece of proprietary software I would consider purchasing, if I had the money to, since mainly what you're paying for is support and the user interface supporting the bottom-level code. Also, yea it's not really vendor lock-in because it works across many platforms - but python is pretty hard to beat when working with libraries.

Here are some videos of our OT1s doing work with our codebase. When in "build-mode" we run about 3 at a time, cloning about 300 plasmids a day.

(At the end of this video, you can see how we're doing the serial dilutions. Extremely important to note: you want to slowly dispense the liquid above the plate, creating a small droplet that sticks to the sides of the tip, and THEN move down to drop the droplets while stabbing the agar a little. If you do it when you're already down in the agar, you're gonna have a bad time)

Antha removes the vendor "lock-in" that you are talking about and allows for cross-platform workflows (which becomes useful when you are working in a DNA foundry environment). And when you already have a $30 000 robot it's difficult to justify to your PI to buy a $10 000 one... especially when that robot is already fully equipped with all of the accessories.

I completely agree though that the opentrons is great for every day work in the lab and its programmability makes it very attractive.

What makes it easier to justify?  After Koeng's email on how wonderful programmability without vendor lock-in is, I don't get you.
