You are encouraged to discuss the material with the instructor, course assistants, and your classmates, but you are not allowed to copy answers or code from others in the class or other sources, nor are you allowed to share your answers or code with others. If you use generative AI to help you with your work, you are obligated to cite the source and nature of the help; for example, if you turn in code generated in whole or in part by generative AI, you must cite the AI software in the comments, and you are required to understand how and why the code works. (Note also that electronics are not available during tests, so submitting code you do not understand will not help you prepare for tests.) ''Anyone copying answers or code, or providing answers or code, or becoming aware of others doing so without reporting to the instructor, is in violation of the honor code.'' |

==Prerequisites== |
|||
'''[[Coursera Resources|This page collects together useful supplemental material to the Coursera courses]]'''. |
|||
Linear algebra, first-order linear ODEs, freshman-level physics/mechanics, a bit of programming background. |
|||
The general flow of the class will be the following: |
|||
==Grading== |
|||
* Before class, watch the videos, do the lecture comprehension quizzes associated with each video, do the associated reading, and participate in any "discussion prompts" on Coursera. You should plan to bring any questions or confusion to class. In general, I recommend that you first watch the videos to get a quick understanding of the material of the chapter, then follow up by reading the appropriate sections of the book. The videos are short and dense, so don't expect to get by only watching the videos. You will need to read the book, then do the exercises, to gain mastery of the material. |
|||
* In class, I will briefly review the lecture comprehension quizzes and the material that was covered, get a little discussion going and take any questions, and then ask you to work on a practice exercise either individually or in small groups. If time remains, you may work on homework together. I will be available to help. |
|||
* On days when a homework is turned in, I will leave time for any questions about it. On days before a quiz, I will spend as much time reviewing the material covered by the quiz as you would like. |
|||
30% of your final grade will be from your Coursera grades (which I expect to be nearly perfect), 30% from assignments outside of Coursera, 20% from quiz 1, and 20% from quiz 2. |
|||
==Student-Created Exercises== |
|||
==Course Text and Software== |
|||
All students will be responsible for creating a practice exercise, consisting of the exercise and the solution. A good exercise should test an important concept in the context of a real robotics application (e.g., motion planning for a quadrotor, robot localization, computer vision, grasping, etc.), require the learner to understand and apply equations in the book or use the book's software, and require a bit of thought (i.e., not just "plug and chug" questions). For many exercises, a good figure or two is helpful. You could use a figure of a real robot and add your own annotations to it (e.g., frames or objects in its environment), or you could hand-draw something, or you could use V-REP or other software to help create the figure. You should not confine your question to an application discussed in the textbook. Make your exercise interesting and motivating! Exercises that require synthesizing two or more concepts or equations are more interesting and useful. |
|||
This course uses the textbook ''Modern Robotics: Mechanics, Planning, and Control'', Kevin M. Lynch and Frank C. Park, Cambridge University Press 2017. If you find an error or typo in the book, please '''[http://hades.mech.northwestern.edu/index.php/Modern_Robotics_Errata report it here].''' |
|||
You will create your exercise using [https://en.wikipedia.org/wiki/LaTeX LaTeX] (pronounced "lay teck" or "lah teck"), the standard for scientific document preparation. [https://www.overleaf.com/ Overleaf] is a free online implementation of LaTeX. To get started on your exercise, |
|||
[[Coursera_Resources#Things_you_should_complete_before_taking_any_course|Get the book, install and test the Modern Robotics code library, and install and test the CoppeliaSim robot simulator.]] You will program in Python, Mathematica, or MATLAB in this course. |
|||
# Download [[Media:ME449-exercise.zip|'''this .zip file''']] and uncompress it. There are four files: main.tex, prelims.tex, screw.pdf, and happy-face.jpg. |
|||
# Create an account on [https://www.overleaf.com/ Overleaf]. |
|||
# Create a new (blank) project on Overleaf called "exercise." |
|||
# Upload the four files main.tex, prelims.tex, screw.pdf, and happy-face.jpg to this project. (You may get a warning that your default main.tex file is being overwritten; don't worry about it.) |
|||
# Click on main.tex to see your main LaTeX document. |
|||
# Press the "Recompile" button to see the pdf document that is compiled from the four files. You can download the pdf file, or all the "source" files, by clicking on "Menu" and choosing which to download. '''[[Media:ME449-exercise-output.pdf|This is the .pdf file you should have created.]]''' |
|||
'''[[Modern Robotics Linear Algebra Review|Here is a linear algebra refresher appendix to accompany the book.]]''' |
|||
main.tex is the main file of the project, and the only one that you will edit, so you should understand what is going on in that file. prelims.tex tells LaTeX what packages to use and defines some macros, e.g., \twist creates <math>\mathcal{V}</math> and \wrench creates <math>\mathcal{F}</math>. screw.pdf and happy-face.jpg are image files that get included in the document. You will create different image files depending on your exercise. |
|||
==Approximate Syllabus and Schedule== |
|||
To learn more about typesetting in LaTeX, google is your friend! Try googling "latex math" or "latex math symbols," for example. |
|||
Here is a summary of the structure of the course. '''All items are due 30 minutes before the associated class time (1:30 PM Central). The deadlines are controlled by Coursera, so do not be late!''' You may work ahead if you wish, but then you won't get as much out of the classes. |
|||
You will turn in the source for your exercise as well as the final pdf file. |
|||
* Coursera refers to "weeks," but ignore this; our course modules are not a week long. |
|||
* Before some classes, you should complete a quiz on earlier material. |
|||
* Before most classes, you will watch the associated videos on Coursera and answer the "lecture comprehension" (LC) questions. (Designed to be relatively quick, to solidify your understanding.) |
|||
* You are encouraged to read the corresponding portions of the textbook after watching the videos. I suggest you watch first, then read, then possibly re-watch, but you can determine what works best for your learning style. |
|||
* During the class period '''after''' you watch those videos, I will typically summarize what we learned, work a problem, take any questions you have about the material, and possibly assign you a problem to work on. |
|||
* There are two kinds of assessments on Coursera (Coursera refers to both of them as "quizzes"): "lecture comprehension" questions (LCs), which are short and immediately follow lectures, and summative quizzes, which are usually longer assessments/assignments occurring at the middle or end of a chapter. |
|||
* Within Coursera there are also "discussion prompts," open-ended group questions that you should reply to (responses can be simple) and forums where you can post questions and reply to other students' questions. |
|||
* Assignments outside Coursera will be submitted through Canvas. |
|||
Below is the approximate syllabus and schedule. Next to each date is the Coursera material that should have been covered '''at least 30 minutes before''' that class. "LC" refers to brief lecture comprehension questions that should be completed before that class, and "quiz" is a longer summative quiz on earlier material. |
|||

If you ever think a problem is stated incorrectly, not enough information is given, or it is impossible to solve, don't panic! Simply make a reasonable assumption that will allow you to solve the problem (but clearly state what this assumption is), or indicate why it is not possible to solve the problem. |
|||
'''As mentioned above, in the Honor Code:''' You are encouraged to discuss the material with the instructor, course assistants, and your classmates, but you are not allowed to share your answers or code with others. Anyone asking for answers or code, or providing answers or code, or becoming aware of others doing so without reporting to the instructor, is considered in violation of the honor code. |

Assignments are graded based on correctness, how well you organize your homework (it should be easy to understand your thinking and easy to find your responses), and how well you follow the submission instructions below. You will lose points if you don't follow these instructions. If more detailed submission instructions are given with a particular assignment, make sure to follow those, too. |
|||
0. '''Upload on time! Late submissions are not accepted.''' The cutoff time is 30 minutes before class the day the assignment is due. |
|||
'''You will not receive credit if you just give an answer. Your solution must demonstrate how you got the answer. It must be easy to follow.''' |
|||
1. Only upload one zip file or rar file for each assignment; |

Simply make a reasonable assumption that will allow you to solve the problem (but clearly state what this assumption is), or indicate why it is not possible to solve the problem. |
|||
2. In your zip file or rar file, include all source codes in their original form, such as .cpp, .m, .py, .nb. |
|||
'''Instructions for uploading assignments to Canvas:''' |
|||
3. If there is a demo, combine the screen shots into one SEPARATE pdf file, OR, show the results in one SEPARATE .txt file (DON'T show them in your source code file format, e.g. .nb file), and include it in the zip file (or rar file). |
|||
4. Always include output of your code running on the exercises, particularly in case the grader has problems running your code. Also, always create a script (for example, titled ex6-9 or something) that the grader can easily invoke for each exercise. Don't expect the grader to search through your code to find sample code to cut-and-paste. Make it as easy as possible for the grader (you can include a "README" file in your solutions, for example). |

|||
:: 1) Exercise 3.1, except the y_a axis points in the direction (1,0,0). |
|||
:: 2) Exercise 3.2, except p = (1,2,3). |
|||
:: 3) Exercise 3.5. |
|||
:: 4) Exercise 3.9. |
|||
:: 5) In Figure 1.1(a) of the book is an image of a UR5 robot, with a frame at its base and a frame at its end-effector. Eyeballing the end-effector frame, approximately write the rotation matrix that represents the end-effector frame orientation relative to the base frame. Your rotation matrix should satisfy the properties of a rotation matrix (R^T R = I, det(R) = 1). The x-axes are in red, the y-axes are in green, and the z-axes are in blue. |
|||
:: 6) Write a program that takes a set of exponential coordinates for rotation from the user as input. It then prints out the following: (a) the corresponding unit rotation axis and the angle of rotation about that axis; (b) the so(3) 3x3 matrix representation of the exponential coordinates; (c) the 3x3 SO(3) rotation matrix corresponding to the exponential coordinates; (d) the inverse of the rotation matrix from (c); (e) the 3x3 so(3) matrix log of the matrix from (d); and (f) the corresponding exponential coordinates for the so(3) matrix (e). Use the code from the book and write your program in Mathematica, MATLAB, or Python. Turn in your code and the output of an example run using (0.5, 1, 0) as the input to part (a). |
|||
:: 7) Write a function that returns "true" if a given 3x3 matrix is with a distance epsilon of being a rotation matrix and "false" otherwise. It is up to you to define the "distance" between a random 3x3 real matrix and members of SO(3). Test the function on two matrices, neither of which is exactly in SO(3), but one of which is close (so the result is "true") and one of which is not. Turn in your code and provide the test run output, which also outputs the distance to SO(3) that you defined. |
|||
:: 8) Following up on the previous exercise: describe (don't implement, unless you want to) a function that takes a "close by" 3x3 matrix and returns the closest rotation matrix. How would you use the fact that R^T R - I must be equal to zero to modify the initial 3x3 matrix to make it a "close by" rotation matrix? Would the function be iterative? You are free to do some research online, but as always, '''cite your sources'''! |

|||
At home: |
|||
* For every assignment, you should submit a single zip file, named FamilyName_GivenName_asst#.zip. This zip file should include a single pdf file with answers to all the questions, including screen shots, text logs of code running, etc. Always include output of your code running on the exercises, so the grader can see what you got when you ran your code. You may scan handwritten solutions (provided they are neat!), but in any case, all answers should be in a single pdf file. DO NOT UPLOAD SCANS AS JPGS! THEY MUST ALL BE COMPILED INTO A SINGLE PDF FILE. |
|||
: Final assignment work |
|||
* You may be asked to include in your zip file all source code in their original forms, such as .m, .py, or .nb. Always create a script that the grader can easily invoke to run your code for a particular exercise. Don't expect the grader to search through your code to find sample code to cut-and-paste. Make it as easy as possible for the grader (you can include a "README.txt" file in your zip file, for example, to tell the grader how everything works). Your code should be commented well enough that it is easy for someone else to pick it up and understand more or less how it works. All student-written code must be submitted; do not submit any standard MR code. |
|||
* If you include movies, keep them short and clear. They should only be a few MB in size. For example, you don't need super high resolution, 60 fps, etc. |
|||
* All plots should be labeled (axes, legends, titles) with appropriate units. |

Supportive Class Environment
All members of this class (instructors, course assistants, students) are expected to contribute to a respectful, inclusive, and supportive environment for every other member of the class.
We are partners in your education; help us help you get the most out of this class. Please engage as much as possible during our class meetings!
Honor Code
You are encouraged to discuss the material with the instructor, course assistants, and your classmates, but you are not allowed to copy answers or code from others in the class or other sources, nor are you allowed to share your answers or code with others. If you use generative AI to help you with your work, you are obligated to cite the source and nature of the help; for example, if you turn in code generated in whole or in part by generative AI, you must cite the AI software in the comments, and you are required to understand how and why the code works. (Note also that electronics are not available during tests, so submitting code you do not understand will not help you prepare for tests.) Anyone copying answers or code, or providing answers or code, or becoming aware of others doing so without reporting to the instructor, is in violation of the honor code.
Northwestern University Syllabus Standards
This course follows the Northwestern University Syllabus Standards. Students are responsible for familiarizing themselves with this information.
Getting Started
Do the following things as soon as possible:
- Buy the book "Modern Robotics" or download the free electronic preprint version. (Though the Cambridge-published print version is the "official" version, the differences are mostly layout and either will work for this course.)
- Download the Modern Robotics software. You can program in Python, MATLAB, or Mathematica. Most students use Python or MATLAB, but any of these is fine.
- Download, install, and test the CoppeliaSim robot simulation software.
- Accept your invitation to the Coursera course.
Course Summary
Representations of the configuration and spatial motion of rigid bodies and robots based on modern screw theory. Forward, inverse, and differential kinematics. Robot dynamics, trajectory planning, and motion control. Wheeled mobile robots and mobile manipulation.
Prerequisites
Linear algebra, first-order linear ODEs, freshman-level physics/mechanics, a bit of programming background.
Grading
30% of your final grade will be from your Coursera grades (which I expect to be nearly perfect), 30% from assignments outside of Coursera, 20% from quiz 1, and 20% from quiz 2.
Course Text and Software
This course uses the textbook Modern Robotics: Mechanics, Planning, and Control, Kevin M. Lynch and Frank C. Park, Cambridge University Press 2017. If you find an error or typo in the book, please report it here.
Get the book, install and test the Modern Robotics code library, and install and test the CoppeliaSim robot simulator. You will program in Python, Mathematica, or MATLAB in this course.
Here is a linear algebra refresher appendix to accompany the book.
Approximate Syllabus and Schedule
Here is a summary of the structure of the course. All items are due 30 minutes before the associated class time (1:30 PM Central). The deadlines are controlled by Coursera, so do not be late! You may work ahead if you wish, but then you won't get as much out of the classes.
- Coursera refers to "weeks," but ignore this; our course modules are not a week long.
- Before some classes, you should complete a quiz on earlier material.
- Before most classes, you will watch the associated videos on Coursera and answer the "lecture comprehension" (LC) questions. (Designed to be relatively quick, to solidify your understanding.)
- You are encouraged to read the corresponding portions of the textbook after watching the videos. I suggest you watch first, then read, then possibly re-watch, but you can determine what works best for your learning style.
- During the class period after you watch those videos, I will typically summarize what we learned, work a problem, take any questions you have about the material, and possibly assign you a problem to work on.
- There are two kinds of assessments on Coursera (Coursera refers to both of them as "quizzes"): "lecture comprehension" questions (LCs), which are short and immediately follow lectures, and summative quizzes, which are usually longer assessments/assignments occurring at the middle or end of a chapter.
- Within Coursera there are also "discussion prompts," open-ended group questions that you should reply to (responses can be simple) and forums where you can post questions and reply to other students' questions.
- Assignments outside Coursera will be submitted through Canvas.
Below is the approximate syllabus and schedule. Next to each date is the Coursera material that should have been covered at least 30 minutes before that class. "LC" refers to brief lecture comprehension questions that should be completed before that class, and "quiz" is a longer summative quiz on earlier material.

Assignments
As mentioned above, in the Honor Code: You are encouraged to discuss the material with the instructor, course assistants, and your classmates, but you are not allowed to share your answers or code with others. Anyone asking for answers or code, or providing answers or code, or becoming aware of others doing so without reporting to the instructor, is considered in violation of the honor code.
Assignments are graded based on correctness, how well you organize your homework (it should be easy to understand your thinking and easy to find your responses), and how well you follow the submission instructions below. You will lose points if you don't follow these instructions. If more detailed submission instructions are given with a particular assignment, make sure to follow those, too.
You will not receive credit if you just give an answer. Your solution must demonstrate how you got the answer. It must be easy to follow.
If you ever think a problem is stated incorrectly, not enough information is given, or it is impossible to solve, don't panic! Simply make a reasonable assumption that will allow you to solve the problem (but clearly state what this assumption is), or indicate why it is not possible to solve the problem.
Instructions for uploading assignments to Canvas:
- Upload on time! Late submissions are not accepted.
- For every assignment, you should submit a single zip file, named FamilyName_GivenName_asst#.zip. This zip file should include a single pdf file with answers to all the questions, including screen shots, text logs of code running, etc. Always include output of your code running on the exercises, so the grader can see what you got when you ran your code. You may scan handwritten solutions (provided they are neat!), but in any case, all answers should be in a single pdf file. DO NOT UPLOAD SCANS AS JPGS! THEY MUST ALL BE COMPILED INTO A SINGLE PDF FILE.
- You may be asked to include in your zip file all source code in their original forms, such as .m, .py, or .nb. Always create a script that the grader can easily invoke to run your code for a particular exercise. Don't expect the grader to search through your code to find sample code to cut-and-paste. Make it as easy as possible for the grader (you can include a "README.txt" file in your zip file, for example, to tell the grader how everything works). Your code should be commented well enough that it is easy for someone else to pick it up and understand more or less how it works. All student-written code must be submitted; do not submit any standard MR code.
- If you include movies, keep them short and clear. They should only be a few MB in size. For example, you don't need super high resolution, 60 fps, etc.
- All plots should be labeled (axes, legends, titles) with appropriate units.
