No problem! Channels like Articulated Robotics is tricky, I'm not aware of too many more. I'll send some of my favorite technical channels that do maths, programming, electronics, and some robotics: Stuff Made Here: www.youtube.com/@StuffMadeHere - really excellent videos, including a puzzle-solving robot to check out! Computerphile: www.youtube.com/@Computerphile - great computer science videos. Take a look at the AI videos by Rob Miles in particular for AI in robotics: ru-vid.com/group/PLzH6n4zXuckquVnQ0KlMDxyT5YE-sA8Ps Numberphile: www.youtube.com/@numberphile - similar to computerphile, but more about pure mathematics Simone Giertz: www.youtube.com/@simonegiertz - great DIY videos, including some with robots in Michael Reeves: www.youtube.com/@MichaelReeves - uses tech in entertaining videos (not intended to be as educational!) Electroboom: www.youtube.com/@ElectroBOOM - electronics videos with technical explanations Hope that helps - I'm sure there are more great channels I'm not aware of!
