Watching videos from Brian Douglas is a huge reason why I decided to go back to school to study controls, and now also why I can't stop researching autonomous robots. These videos are so unbelievably good, and bring so much joy.
Wow! This simplifies complex ideas quite comprehensively in a way that is easy to understand! The visuals really help as well! Thank you for making such an incredible resource free!
Love how you go through not only the solution, but the motivating context and problem framing. Details like that are what distinguish truly great teachers. Keep it up!
Sir, I just got a hold of your map of control theory, and have been watching your videos for some time. Congrats on your work. Honest, you deserve a Nobel prize!
The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
I operate an autonomous floor-cleaning robot in a high traffic retail space. That's a prime example of one of the many problems an autonomous vehicle must solve: navigating safely around unpredictable human obstacles. Because let's face it: a lot of retail customers are downright oblivious to everything around them. How do you predict what a human will do when even the human has no clue what they're doing?
hey, how can I also make writings like that? Do I need a tablet and a specific pen? I have a tablet and stylus, but it certainly does not look like that.
