Experimental surgery performed by AI-driven surgical robot
The AI on display, Surgical Robot Transformer[1], is based on the work of Action Chunking with Transformers[2]. These are both transformer models, which means they are fundamentally token-based...

Cara – High Precision Robot Dog Using Rope
I recommend a Brachiograph build. It will introduce you to some fundamentals of PWM and inverse kinematics. It is well documented but not cookie-cutter. Using a Raspberry Pi will give you more direct access to running the servos than the microcontroller experience. All the parts are infinitely reusable afterward if you don't want to keep it around.

Making my first robot as a software engineer
Reminds me of the https://www.brachiograph.art/ . I tried to replicate this, but found the position drifted and jittery.... Probably due to poor glueing technique...

Getting arty with a Pi
This is absolutely not my invention! I came across it in the most recent issue of The MagPi magazine, and immediately wanted to build one. The BrachioGraph was created and documented by Daniele Procida, all of the code is on GitHub, and it has been around for a number of years, since originally being introduced at a PyCon in 2019.
