The material itself is worth a few stars. Clearly lots of work has gone into making some interesting interactive matlab demos. some of the quizzes are unnecessarily confusing.

Very uneven. There are some good insights and ideas in there, but no way will a beginner be able to make sense of this. It's more like a sort of refresher/inspiration course.

It generally introduced mobility. But could have introduce more about the analytical model of these templates in this master level course.

I found it hard to understand some topics especially when instructors are just reading from the slides. I really wish there was a bit more time spent on explaining the intuition behind some of these concepts so that people completely new to the field could understand what is the meaning of it all. I found quizes even more disconnected from the material and either way too easy or requiring background knowledge. Overall, I enjoyed the material and was just disappointed with exercises and some of the instructors.

The course is not bad, but the information of the slides doesn't gives you much information to solve the questions. You have to go to other resources to solve the math questions.
The simulations are OK, very practical and comprehensive but there is no math information about the movement or equations of motion on the slides, off course, if you have the matlab code you can do reverse engineering and aim the goal. If you expect to learn about robotics motion and mobility you have to go to other books of these themes.
There are too much questions in my opinion and are tedious to solve or answer.

There must be something wrong to spend time on google&wiki much more than the course content.

The course is very interesting and full of valuable information, but the evaluations were made to fail. It requires a lot of additional research and the apparent intention of not passing the different quizzes becomes almost frustrating. It is full of tricky questions.

The Course material and method of testing the understanding of the student needs to be improved. Despite the low quality of the quizzes, the course is very inspiring. The examples showed are very good and the lectures concentrated on teaching the underlying concept rather the Mathematics involved, which was refreshing.

This course provides a lot of informations in a very superficial way. The lack of handouts for most of the lectures doesn't help the learning at all. The abuse of quizzes instead of more comprehensive programming assignments doesn not allow the student to learn through direct experience and usage.

If you love to see a couple of entertaining movies about robots and some interesting concepts about them, grab some popcorn and take this course, because, hey, it’s about cool robots!!
If you are crazy enough and actually want to learn something new or even consider to get the certificate, I would not recommend to participate in this course. The videos are quite ok and cover a good part of what I think this course should be about. But there are a bunch of quizzes, which are sometimes quite off the lecture material and you have to research a lot to get all of the questions right. I managed to solve all quizzes in the end, but it was some kind of a frustrating and discouraging process.

In some ways good, but deeply flawed. The assignments were weakly correlated with the lectures, and no explanation was given for correct answers or for incorrect answers.
I believe the authors would have benefited greatly from getting outside feedback from an advanced undergraduate or beginning graduate student, rather than each other.

This course is a disappointment after the previous two courses in the specialisation. It tries to cover too many topics. As a result it provides a shallow introduction to many topics rather than deep coverage of any one topic. I do not feel I have learnt anything of substance.
Many of the assignment questions are poorly written. To name one example, assignment 3.1.1 question 3 has at least three correct answers, but the grader accepts only one of them. I wasted hours trying to work out why it was marking my answer wrong.
The lectures by the TAs are delivered in a "robotic" tone if you'll pardon the pun. They are reading off an autocue and it shows.

This course covers very interesting topics, but there are some serious shortcomings in the lectures. Too much information is just omitted or taken for granted. Some of the lecturers are rather inexperienced. Reading or reciting mathematical expressions in a monotonous voice without actually pointing to the visual representation of the lecture material makes it very difficult to follow. Better care should also be taken with the quizzes - if one looks at the comments or questions posted by some learners, it is clear that we simply don't understand the question, or a question is answered correctly in essence , but the quizz expected more (or less) precision without stating so . Finally for some reason the support from Technical Advisors was also lacking in the specific session that I did, contributing to my frustration and rather negative experience of what could be a very good course

I feel that the lecture material lacks proper explanation of the key concepts but the questions in quizzes are good although the lectures should have been more conceptual rather than theoretical

I find the course informative. But it seems like the lectures were really focused bragging about the robots(Hrex,Jerboa,hopping robot etc...) . I'm sure they are good examples and were needed to explain a lot of concepts, but this course doesn't take you through design procedures, how to simulate robots on MATLAB, tuning PID parameters doesn't really help anyone, how to make a simulation on MATLAB?, no information on choosing actuators.I was hoping to design algorithms like in Aerial robotics/Computational motion planning and perception. This course is a collection of data and information. There is hardly any problem solving.
On the brighter side this course give you a different perspective on designing robots and where the present R&D in universities is heading.

The course has a lot of interesting material, but I believe that a few points may be improved:
1) Exercises with Matlab are not programming ones (except for the PD controller). In my opinion, more detailed exercises (with a guide for solving them) would help to understand better the concepts behind the theory. For example, programming a rimless wheel or a SLIP template.
2) The course has a strong emphasis in theory. Some of the lectures were boring an difficult to follow. As I said before, a more practical approach would be more rewarding.
3) Quizzes were sometimes based on intuition, or topics outside of the course, rather than topics learned from the lessons.
On the other side, the TAs were highly involved in the course. In addition, an extensive list of additional resources (books, papers) is a plus.
I believe that the following sessions will be better than the first one!

I think this was a poorly structured online course. Especially for someone who is attempting this course having experienced two excellent previous courses in the specialization. It was good only in few patches but the link was seriously missing. I realize this area is a bit more advanced but with all due respect to the knowledgeable instructors, they could have emphasised more on basic building blocks rather than cramming in so much information which my bandwith couldn't handle it. I did guesswork in almost all the quizzes after week 2 which further adds to my disappointment.
I think the Robotics specialization is better off without this course because there is little or no value addition here. Expecting a lot better from the next course in the series.

The worst course I took in Coursera. The majority of the quizes are vaguely explained in the lectures, or not explained at all. Lots of research needed, bugs on the codes and assignments and many boring videos. I don't understand why it stays available. If you can, don't waste your money in this one, go for other Robotics courses.

It is not well done as the previous courses. The quizzes usually do not concern the topic of the lessons or better, the lessons do not help in anyway to solve the problems.

This is the worst course online I've done so far. I would not recommend it to anyone as it stands, regardless of the student's background, this course is just poor and lacking.
The premise of this course is a promising one, the topic is still in its infancy and seems very interesting. Having said that, this is about everything positive that I can say about this course.
For starters, the videos seem good at first, but later it becomes very superficial and monotone. The content is many times just rushed through and it's visible that the lecturers at several occasions have difficulty even to read their own slides!
However, the worst part of the course are the quizzes. There are 24 graded quizzes in total, to pass the course you need to pass all 24 of them! To make matters worse, the minimum passing marks for each quiz is 80%, that wouldn't have been such an issue if most quizzes had 5 or more questions, which is not the case, most of the quizzes have 4 or less questions. This is such an unreasonable requirement, if you miss only one question in a quiz with 3 questions there's already no chance to pass the course!
The content of each quiz is also very troublesome, we are essentially being graded for trivia, a considerable number of the questions are very superficially related to not related at all to the subject of each lecture. Instead of using the questions to delve deeper into the topic at hand, they only create confusion with futilities. A little example, the topic of a subject was about the mechanical properties of using multiple templates and a question in its quiz was about an electric circuit that is never shown in the question itself, only briefly shown in the lecture video for about 10s, minimal information is given without any explanation of what they mean and we are asked to enter a formula as the answer for which also almost no information is given about which notation we should use for the formula itself.
There are other cases where there are multiple choice questions which have incorrect answers accepted by the grader. In one instance, two of the options available are contradictory to each other, however the accepted answer was the one involving both. In another instance, there was more than one solution available to an answer, however the grader accepted only one and there was no information in the question itself to narrow down the possible answers to the desired one.
Finally, there is no active community by the TA and professors, I have never had a single answer form a TA or professor, only sporadical replies from a mentor, who has no authority to fix any issue by him or herself.
All these issues just point to how poorly this course was designed. It had such high hopes, but they fell short flat. In doing this course, I found myself reverse engineering most of the questions just to try to find an accepted answer and try to understand what it meant. The imposed 8-hour period between attempts at the quizzes only hindered my progress. I was focused and engaged in studying for each quiz, however, after 3 failed attempts I had an imposed break period that makes little sense. In the end, this course only made me feel like the very object of my learning: a robot.
I am really disappointed with this course.

This course, was really bad structured, was often the discrepancy between the information provided in the videos and the questions in the Quiz. Also a lot of time the system was very picky to take an answer like correct, just because the format used, for example e!=E in one equation, and because this was necessary a lot of guessing in order to find how the system take the answer by correct.
But really the worst was the discrepancy between the video and the quiz, because my impression is that the videos were cut to fix in the time, but they were cut a lot, missing important information to be used in the quiz.

The lectures are a very brief overview of topics, with nothing actually taught. The quizzes are entirely disconnected from the lectures and require basically just finding and reading the right wikipedia pages. This course is an absolute joke and an embarrassment to UPenn, Coursera, and everyone involved. It's clear that the instructors don't care about student's actually learning anything. Compare this to the "Underactuated Robotics" course on EdX.
