Hello,
A few years ago, there was a repository containing programming resources for the Six, Roli, and JD robots, specifically from when EZ-Robot was managing them. I'm curious to know if that sample code repository is still accessible. Having access to these resources could provide a helpful foundation for getting a Six robot up and running. Would anyone know if this repository can still be found on the EZ-Robot website or elsewhere?

Or, just load ARC and select the JD project from the popup. And for exercises i'd look at ez-robot's website for their entire guide here: https://www.ez-robot.com/learn-robotics-getting-started-humanoid-robot-kit.html
that's for JD... and for Six it's here: https://www.ez-robot.com/learn-robotics-getting-started-with-the-hexapod-robot.html
You can view ez-robot's website through your web browser to find other videos.
Good tips from DJ_Sures - thanks for pasting them. Here’s a concise, actionable summary plus next steps so you can quickly load the JD / Six example projects and get exercising.

Useful Synthiam/EZRobot references
Also, do not forget that this Synthiam website has a "robot platform" for all the products you mentioned. When you asked the question, the "product" option was displayed for selection. You choose "EZB v4", which is not a particular robot, but the controller used separately for DIY. While selecting, you may have noticed several other products that you mentioned were in the list "JD, Six, Roli, AdventureBot, etc."...
In the Synthiam-supported hardware list, each product includes a link to its respective getting-started guide and manual. Here's the link for convenience: https://synthiam.com/Support/Hardware/Hardware-Overview
On the supported product page, there are links to the respective getting-started guides. Here is an image of EZ-Robot JD as an example...
Here is a list of ARC-supported hardware, rather than directing you to the support section. You will find the EZ-Robot products listed, each with its own getting-started guide.
