О курсе

How can robots use their motors and sensors to move around in an unstructured environment? You will understand how to design robot bodies and behaviors that recruit limbs and more general appendages to apply physical forces that confer reliable mobility in a complex and dynamic world. We develop an approach to composing simple dynamical abstractions that partially automate the generation of complicated sensorimotor programs. Specific topics that will be covered include: mobility in animals and robots, kinematics and dynamics of legged machines, and design of dynamical behavior via energy landscapes....

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 vast and intuitive course.I found all the information required to design my own legged robot ! I will try and design my own . Thank you so much !

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

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.

Interesting class, but somewhat frustrating at times. I found the quizzes very conceptual, which was interesting, but trying to find the correct answer with no feedback as to how something was right or wrong made for a weaker learning experience. Had there been some feedback to understand why something is correct or not, I think that would enable more learning.

I also think more emphasis on Forward Kinematics and Inverse Kinematics would help ground this class as a more general class for students interested in robotics. Introduction to Jacobians and how we can calculate end effector forces with respect to joint torques would really help interlace this class with some of the other classes in this Robotics specialization. It seems like it sticks out the most.

Still. Interesting class and I learned some new stuff!

Theme of the course is very interesting but teachers are not much didactic.

Good teachers but a lot of questions in the quizzes were very ambiguous and unrelated to the Course Content.

The course could give more worked out examples in lecture as opposed to just pure theory and leaving the examples for the students to figure out in the quizzes. A lot of students learn by example.

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.

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!

Not the best course of the serie. It is a pity because I had great expectation in this course.

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.

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.

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.

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.

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.

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.

the material in this course are explained briefly ,there is no projects like the other courses or programming assignments to understand the concept ,it is just a theoretical course and poorly explained concepts

I don't think this was a useful course. The content is a very superficial overview of legged mobility ( which is already a niche area) and the quizzes/exercises were often poorly worded and ambiguous. I wouldn't have done this course if it weren't part of the Robotics Specialization track.

Aunque el curso es interesante es necesario investigar mucho en internet para poder realizar parte de las tareas. En toda esta serie de cursos no se pide requisito alguno, pero es necesario saber utilizar matlab para poder realizar las tareas, que dicho sea de paso, no dejan aprendizaje alguno. Un mejor nombre para todos estos cursos sería "aprende a utilizar matlab como puedas". En los videos explican algunas cosas y luego se pide completar una función que realiza una tarea mínima. En ocasiones tengo que leer varias veces la asignación de tarea, leer con cuidado el código existente, y ver dos o tres videos para entender lo que debo hacer. Tengo doctorado en física y soy profesor universitario, y si para mi es complicado entender qué debo hacer, no quiero imaginar lo que sería para un estudiante que cumple con los requisitos para tomar este curso, es decir "no experiencia previa". De un tiempo para acá se debe utilizar matlab en linea, que es de lo peor que puede existir: es lento y casi inutilizable. Con esto, entonces no se cumple con el trato original. Es una pena que se deba pagar por anticipado por estos cursos fraudulentos.

Poorly designed course which tests people on things that are not taught.
