The course is very good.
The classes are well taught and show general concepts. It is necessary to do research on the internet, to solve the assignments. This is not a bad thing in my point of view

I think this is very good course of aerial robotics research. Being a student of robotics, I feel that some of stuffs in this course needs a good background in control and mechanical engineering.

This course is a great course for beginners who are stepping into the world of robotics and the perfect course to start a specialization. The course content is exciting and there are a lot of instructional concepts. However, I was not satisfied with the way the content was presented. Being used to the chalk and talk environment, and following online videos where the tutor writes the equations on the screen as they go through them, the " PPT slides and voiceover" method did not attract my attention. But the content of the course kept me going. I found some of the qualitative quiz questions quite difficult as they were not taught in the class explicitly.
Understanding quadrotors, I see that there could not be much done when it comes to programming tasks. Programming tasks Weeks 2 and 3 were extremely easy to code, but tuning the PD gain parameters was the most infuriating task. Even when I got the correct code for Week 3, I was doubting whether I made any mistakes in the code for a long time while the issue was caused by a bad PD gain ratio. The tuning part could be removed by providing a considerable range of possible values of the gains. This would save a lot of wasted time. That being said, I found the final task to be insanely interesting and the satisfaction of solving the final task was extraordinary. I would also appreciate the work done in creating the simulation model and the way the quadcopter was visualized and the trajectory was plotted.
Overall, this course pretty much teaches you all the basic theory you need to know to control a quadrotor. If you dont mind wasting a few hours tuning 6-8 values, you would walk out of this course with great satisfaction.
PS: There are a few videos of quadrotors doing insane stunts both as a swarm and individually inside the course.

I really enjoyed this course and it really hooked me onto this topic, definitely this will not be the last robotics course I am going to follow. That being said there are some points of improvement.
The main parts necessary to program the simulation assignments are covered in the materials, but there are still some of them that need to be pursued independently. Some assumptions have to be made that are not so obvious, I do not know whether it is the intention of this course to do so or not, but since they are minor footnotes that may hinder completely your results, I think they should be made explicit.
The Matlab files available for the course work as intended, what is not so obvious though is how they are intended to work, that is because there is very little documentation about them, it would be great if there was more documentation available, especially for people who have never used such tools before.
Finally, even though I personally enjoyed this course and I think it had an achievable level of challenge for me, I would definitely not recommend this course for total beginners, or people who do not have followed a math, physics or engineering degrees. The way the course is laid out, even if you do not understand the concepts behind each topic you will still manage to answer the quizzes and get the simulations to work eventually, however to truly understand what they mean and be able to replicate them in other environments requires some prior knowledge that cannot be taught in just a few hours.

I really enjoyed this course and felt the material was appropriate in scope and quality for an introduction to Aerial Robotics. I have a few issues with it though.
While this wasn't a problem for me, I feel those who haven't done maths with vectors and matrices before would struggle with the maths presented here.
There was some inconsistency in notation throughout the lectures - though I expect this will be fixed in future runs of this course.
Given how much the programming assignments involved tuning PD controllers, I think there should have been some additional material provided on how to go about doing this.
The difficulty of the last programming assignment came out of nowhere and given that you need to pass all the assignments in order to pass the course, this made it especially stressful. Having gotten almost full marks on the course until that point, the prospect of that all being for naught because I couldn't complete the final assignment in time was incredibly stressful and unfair. The simulation would fail with a Matlab ode45 error - with absolutely no information as to why that should fail. Trying to debug something by guesswork on a time limit is not a valuable educational experience.
I feel all of these issues are fixable though and on balance I think this was a very good course.
