For software support, the software is open source, so the community can keep it going even if we’re no longer around (hopefully not anytime soon).

For repairs, the components are inexpensive enough to simply swap in a new one, and you can always find replacements on AliExpress.

NextJS (and Vercel) is really easy to use ;)

We will have a two-arm version available, as well as a kit for people to convert the current version to two arms—probably in August or September.

Yes, we 3D print and assemble in San Francisco, and ship from there.

It will probably be available in late July. We’re expanding the team, so we might be able to offer it sooner.

I hear you, man. After using 7-DOF arms, there’s no going back to 6 DOF. I’ll try to develop a version and hopefully get it out in August.

We’ll probably have an electronics-only kit available in late July. However, it won’t be much cheaper, as we’re running on a very thin margin.

Kuka had this demo years ago: https://youtu.be/tIIJME8-au8

Nowadays, if you’re running a 2–3B parameter foundation model on a standard computer, you’ll probably get a rollout frequency of 1 to 10 Hz. ACT would be faster, but I still don’t think it’s fast enough.

I need to ship the current orders before taking the next batch, so it will probably be sometime in late July. You can sign up for an email notification for the next batch here: https://vassarrobotics.com/newsletter

XLeRobot and LeKiwi are both great!

The robot is only as good as the amount of time you’re willing to spend teaching it. If you put in, say, 20,000 hours and make "some" hardware upgrades, you can get it to do things like this: https://www.physicalintelligence.company/blog/pi05

I’m running on a very thin margin here. I want to get the robot into the hands of robot lovers without them having to eat McDonald’s all month just to save up for it. (I did that once myself, and I strongly advise against it—it’s really bad for your health, both physically and mentally)

Very good suggestion! They look really promising. I’ll talk to the company to see if the price will be acceptable.

Interesting. Their servos seem to be PWM servos, which are available at a very good price. I would look into how to hook up all the servos—you’ll probably need an MCU to convert USB to PWM for each servo.
