The course was challenging, but fulfilling. Thank you Coursera and University of Pennsylvania for giving this wonderful experience and opportunity that I might not experience in our local community!

The topic was very interesting, and the assignments weren't overly complicated. Overall, the lesson was fun and informative , despite the bugs in the learning tool(especially, the last assignment.)

The lectures were good, but many assignments had errors (graders, errors in code)

So I'll start with the positives. The material was appropriate and interesting and well presented. CJ Taylor is an enthusiastic lecturer and the material was presented in an enjoyable easy to understand way and having finished the course, I definitely want to learn more about computational motion planning.
The problems I have with this course though are numerous. This is the second part of the Robotics Specialization and compared to the first part, this course was very weak. There was very little lecture material and the course felt thin - as if it were 2 weeks of material stretched over 4. There were many instances where the lectures could have gone in to much more detail and just didn't, I appreciate that you can't cover everything in lectures, but would it have killed you to provide or at least point to some good additional reading resources?
The assessments were the worst part. The quizzes barely tested what I had learnt and could mostly be solved by common sense. What I find shocking is that there were so few questions with few multiple choice answer that you could easily brute-force these quizzes if you really wanted to. Compare this to the Aerial Robotics course where the quizzes took time and forced me to think and understand what was discussed in lecture.
The programming assignments were shockingly bad. They were hard for completely the wrong reasons. I spent most of my time on them not coding the solution, but trying to figure out what was actually wanted and fixing bugs that were in the provided code that we WEREN'T EVEN SUPPOSED TO EDIT. The autograder would never tell you why you were wrong, just "I'm sorry, your solution didn't pass all of our test cases." This meant that finding the solution was based on guesswork rather than considered thought. This was made even worse by the fact that some simulations took a long time to run which made iterating guesses very slow - and doing this on a time limit is just pointlessly stressful.
One of the assignments had the solution already in the source code as the instructors had forgotten to take it out.
The final assignment wouldn't even run out of the box without fixing bugs in the provided code. This would have taken seconds to check had the person who wrote it bothered to check their work beforehand.
Thing is, the tasks provided in principle weren't that hard, they were actually kind of too easy. Dijkstra's algorithm isn't that difficult to implement from scratch, and yet all that was asked of us was to implement a small 10 line for-loop. That said, I appreciate that as a software engineer, I might find this sort of thing much easier than most, but even so I don't feel as though the programming assignments helped me learn anything.
Overall, regardless of how interesting the material was, this course was very shoddily put together. I appreciate this is the first time the course has been run, but this really felt phoned in and unacceptable. I paid money for this course and the quality of it is notably worse than most free MOOCs I have taken. I feel ripped off and I sincerely hope that the next section is better otherwise I doubt I will bother to continue until the end. I thought Penn University was better than this.

Prof. Taylor's lectures were clear and easy to understand. The course taught the basics of planning pretty well.
The teaching staff, unfortunately, was completely unavailable. The solution checkers for the Matlab assignments were very brittle and wasted a lot of students' time. There were several queries about the assignments on the Discussion forums most of which did not elicit any response from the teaching staff. The students ultimately figured it out by spending several laborious hours figuring out the peculiarities of the solution checkers, and by helping each other. This certainly soured my experience with the course.

The contents and quality of the video lectures are great.
The quality of the supplementary materials (like the quizzes and the Matlab code) provided by TAs for the assignments are very poor. The assignment guides are written with very poor grammar. The Matlab code is written using the worst coding and documenting practices. The automatic evaluation system (the system for grade the submissions), doest't provide useful feedback. As people can read in the course discussion forums, students have been asking for months for improvements to the grading systems.

This was an interesting course, however there were bugs and errors in most of the assignment materials, which really impaired the learning experience since much of it was reduced to debugging the course organiser's code... Also the 3rd and fourth sections, including assignments, seemed to be rather small and to cover very little material, with little or no supporting material. Moreover, course staff were conspicuous by their absence on the course forums. A stark contrast to the abundance of support provided and material covered in aerial robotics.

The assignments were hard, not because of the contents of the courser, but for understanding the context of the method being implemented (what each variable meant and how it was expressed).
Also, there should be a range of submissions that could be right but having higher or lower scores depending of how long it took to find the path, or how long the path was to reach the goal.

The topic is very important and interesting, but I think that lectures are way very short, and the student is left with some pieces of code that many times don't run in MATLAB 2014 or older.Finally, the graders must be tweaked after reading the forums. I don't know if that is truly the point, but a student may get too much confused with the grader response.

matlab assignments are horrible, very poorly explained and documented and the submission process does not give the correct resulhalf the time. I had to change submissions that looked perfectly correct (and gave correct results) to something that did not look right just to pass the grader.
The course is good, but the matlab part really needs improvement

The assignments in this course take much more time than indicated. Feedback from staff is minimal. If you are not a good programmer, think twice. Nevertheless, the lectures are interesting and well taught. So if you do not want a certicficate, I recommend this.

Sorry but the course videos are really too short and the explanations could be better. I would appreciate if in some cases you would go more into mathematical background/detail. The programming assignments and some grading were in my opinion too strict.

The assignments would be easy except that the provided code has bugs, and some of the assignment details are wrong, making it very difficult to pass the test cases.
There is also very little information on how the work will be graded.

>>Videos are not detailed and comprehensive
>>Video lectures are very short
>>Programming excercises are difficult to do complete
>>The professor's teaching style is not engaging
>>Python should be preferred for such courses

Interesting material, and good assignments. However this is no assistance when by TAs if you have questions, which is important since there is no feedback on assignments and hard to know where you went wrong.

The course could be 1-week long instead of 4. The material offered is introductory level. Quizes are too easy, programming assignments still have bugs, and grading procedures cause a lot of confusion.

The assignments is not focusing on the contents in the lecture but some minor places. It wastes a lot of time to do meaningless work to pass the test. The autograder is really bad.

The Assignments are more of Trial and Error and not very helpful. The Course Material and Content is good. Teaching Staff is nowhere to be found.
