- Goals seem good but the actual course content covered too much of trivial programming and multi-threading that have been thought in several courses before and that should be known by any respectable student in the program anyway. (For example there was one full 2h lecture discussing the concurrent transaction problem with mutexes etc?!)» (Yes, the goals seem reasonable)

- Unprepared assistant that constantly keeps whining about how unintersting the problems are, reading stuff on his iphone during teaching and skipping half of the problems because "matlab does that anyway" without details on how. If i just wanted the final answers to the questions there are better ways to get them than to sit through 2 hours in a lecture hall. One session was more than enough.» (Small extent)
- i avoided the exercises because they were not very good» (Small extent)
- The exercise sessions were not good. The TA was not prepared and seemed uninterested. » (Small extent)
- Were bad structure on the exercise sessions. I didnt seem like Mohammad followed the actual schedule and some exercises were hard to find in the books.» (Small extent)
- Some exercises had nothing to do with the exam» (Small extent)
- Sometimes explanations were not really clear.» (Small extent)
- very hard to learn with a TA that does not want to explain.» (Some extent)

- The literature was okey. But the fact that there were no reading instructions made it very difficult to know what to study. Reading instructions should definitely be made available for next year.» (Some extent)
- Most of the course stuff I learned in class» (Some extent)
- The handouts mainly. Didn"t use the courses book much, only when studying for the exam.» (Some extent)
- A bit messy. Hard to know what is worth reading.» (Large extent)

8. What is your general opinion about the following course topics?


- eg. the CAN-network and it"s pros/cons has been mentioned in many courses, but it would sometime be nice to see how to implement it and perhaps some consequences of it. »
- With a better integration between the project and the lecures the scores might been higher. »

Genomsnitt: 2.2

- Poor, but once it started to work (using 5 different computers and operating systems) it was ok.» (Poor)
- Too complicated to get it working. Pretty good once installed properly but we spent way to much time hazzling with the installation.» (Poor)
- Waste of time. Didn"t teach anything. Installing the toolbox was a bitch and after that then we didn"t even have to do anything with it except hit run and observe the plots. Would have been better if we actually had to use the toolbox to solve some problem, or just remove it and have some throughout lecture about scheduling.» (Poor)
- Was not prioritized because the projcet took all the time.» (Adequate)
- The software didn"t work at first, so that was not so good. But it was a good hand-in that I learned from. Too bad that the TA didn"t understand our questions about it, and we had to explain it to him.» (Good)
- Really hard to install, I spent more time to install truetime than to do the assignment!...» (Good)
- It was a good hand-in, although there were some problems installing the software.» (Good)
- Always nice to learn new Matlab tools and new ways to analyze» (Good)

- Lots of time. Have less time for study to the exam» (Adequate)
- Good, but too much fiddling with the parameters to try get it to balance (which it would not do anyway). The best part was in the beginning, then it sort of got stuck.» (Adequate)
- Will be better with more help and supervision! The balancing projects should have Accelerometers so the students can implement Kalman filters.» (Adequate)
- I think that it was a complete success. However, some groups had more instructions than other group and some group didn"t have any instruction from the beginning. And from my point of vieuw, having no instruction from the beginning made the project more interesting.» (Good)
- To big, takes to much time. Needs to be more help.» (Good)
- awesome. First project on Chamers that covers more then just Matlab/Simulink simulations.» (Good)
- Finally some hands on experience of control. Not every day you see that on chalmers, even realistic computer labs are very rare throughout the program. Would have been good with a fixed problem and a problem that _required_(not artificially) parallel processing and some advanced control technique. Now some of the projects could get away with a simple and slow pi-loop. Also a bit boring when everybody did the same project(ballbot) and still everyone who did that failed. Followup and tutoring-sessions would be good so we know what we did "right" and "wrong" and what other improvements we could have done. Project started too late. Specified grading!!» (Good)
- Good, but very time consuming. Which would be okey if the exam would not be so important for the grade. But in this class both exam-studies and project took a lot of time. Which meant that I didn"t have time to study for the other course as much as should have.» (Good)
- but i wish the lecturer and assistants had done similar projects so we could have someone to ask and preferably be able to make the projects work.» (Good)
- Really interesting and chalenging project! maybe more help would have been good to go further.» (Good)
- But it was very big and there was to little help so it was hard to make the project work. But I learned alot on it.» (Good)
- best part of the class! a lot of fun! It would have been even better if more focus had been on the cuncurrent part of the project, and if the lectures had more to do with the project. An assigned supervisor and a few scheduled supervision sessions is definitely needed. » (Good)
- Just awesome» (Good)
- When I first heard of this it seemed like it was going to be a really fun project. The idea is very good but carried out poorly. The projects were too difficult and no help whatsoever was offered. For next year I hope the main problems will be fixed already so the students can focus on the Real-time control part itself, and not how the gyro drift and backlash has to be solved.» (Good)
- Very fun» (Good)
- It was a really good project. It was a really good idea. I really liked it. Maybe for next year it could be good to have some help sessions for the project.» (Good)

- Better help and/or more time is needed to achieve a balancing robot. Otherwise a simpler task might work as well. » (Adequate)
- Good, but would have been better if it required some preparation and a followup-lab would be good. Now half of the time went to understanding the setup and the remaining time was just trial and error control. A second lab where you would have had time to prepare calculations, algorithms and code would have been good.» (Adequate)
- Need more instructions. How/why we do things. Really would have liked to actually get the robot to stabilize...» (Adequate)
- not enough time to create a working solution, something that would have been good.» (Adequate)
- The litterature for the lab was very bad, and the objectives were very unclear, as well as how to reach them. Also, see question above.» (Adequate)
- ...but needs a lab pm » (Good)
- Very useful for the project!» (Good)
- Could be a bit more prepared. (was in the first session. I think the later sessions were a bit better organised)» (Good)
- if we had been given some assignments before we could have made the robot balance, that would have been better» (Good)

- Still we can not find the course PM on the homepage. That is really bad! » (?)
- Took a LOOOOOOOOONG time until course-PM and lectures came up. Made it very hard to catch up on missed lectures.» (Poor)
- apart from the grading of the reports it was good.» (Adequate)
- Some information was given quite late.» (Adequate)
- Please upload slides and other documents as early as possible, at least before the lecture. Preferably as much as possible available from day one.» (Adequate)
- Even though there were a few problems, most were solved fast by knut.» (Adequate)

- Very poor help for the project, and the exercise sessions should be improved, so the students can ask for help also.» (Poor)
- Good in general but more supervision during the projects would be better.» (Adequate)
- I understand that Knut was very very busy during the course. Which I can understand. But its not optimal for our learning, because I want to be able to go and ask if something is unclear about lectures/projects or something. And the TA was hard to get help from. More consultation for the projects would have been necessary.» (Adequate)
- Knut was very helpful, even if it seemed like he had way to much to do.» (Good)

- Between adequate and high.» (Adequate)
- Handin was given in the end when the projects were at their most critical stage. Very bad timing for such a redundant and time-expensive assignment.» (Adequate)
- We spent a lot of time working with the project.» (High)
- Hard to know how much time that was supposed to put into the project. Should be more information. There should be more steps of grades of the project.» (High)
- High, but not to high. The swedish word "lagom" fits very good here.» (High)
- The project took a lot of time, some of the unuseful time could have been avoided if there had been some more supervision.» (High)
- The project takes A LOT of time!» (High)

- Project took much time» (Adequate)
- Replace truetime handin with double lab-session, or incorporate truetime with the lab somehow.» (Adequate)
- It looks good on the paper, and Knut was really trying, but should be done better for next year. It has potential to be a really good course.» (Adequate)
- It was good to try and program some control algorithms to see how they work in real life.» (Good)
- Needs some fine-tuning to make it better.» (Good)
- a very interesting course, I just wish the lab and projects had given better results» (Good)
- Fun with some new things being introduced! Even if we were the guinea pigs, i think that it was a good class. If the last hick-ups are solved i think it could be a key part of the control education, since the project gives some hands-on experience and opportunity to apply the theory taught. » (Good)
- A really good course !» (Good)
