Interesting, you can’t use their SDK or you can’t load whatever you want on it?

E.g. Unitree R1 has attractive low price but missing the “secondary development” pack (access to Jetson Orin and all the firmware stuff to let you run custom software). It’s all just their software. Useless tool. Click button and it dances. Then what.

I've seen a similar setup with a different Chinese cutting edge product. App access is free, ssh is open, but API keys and the ssh password is priced like a cheap car.
