<br />
'''[[Coursera Resources|This page collects together useful supplemental material to the Coursera courses]]'''.<br />
<br />
The general flow of the class will be the following: <br />
<br />
* 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. <br />
<br />

* 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, perhaps work a problem myself, 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.<br />
* 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.<br />

<br />
<!-- [https://docs.google.com/spreadsheets/d/1cIX4_U8lkWAL6LqQBgDrE5WX1TAmJaD6-ykG7GNACkI/edit?usp=sharing '''Click here for student exercise assignments.'''] --><br />
<br />
'''Bring two printed copies to class Monday Nov 18, for feedback. Turn in the final version online on Wednesday Nov 20 at 1:30 PM, as two files: FamilyName_GivenName.pdf, with the pdf of the exercise and its solution, and FamilyName_GivenName.zip, with all the source files for your exercise taken from Overleaf. Also bring a printout to class on Wed Nov 20. If it is more than one page, staple it.'''<br />
<br />
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 CoppeliaSim 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. Think about what kind of exercise would have helped you to really understand the material. Your questions should be very clearly worded, so anyone can understand it without you having to be there to interpret it for them.<br />
<br />
You should look at the practice exercise document and end-of-chapter exercises for inspiration, but obviously your exercises should not be copies.<br />
<br />
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,<br />
<br />
# Download [[Media:ME449-exercise.zip|'''this .zip file''']] and uncompress it. There are five files: main.tex, prelims.tex, twist-wrench.pdf, table-lamp.PNG, and LampSolution.PNG.<br />
# Create an account on [https://www.overleaf.com/ Overleaf].<br />
# Create a new (blank) project on Overleaf called "exercise."<br />
# Upload the five files to this project. (You may get a warning that your default main.tex file is being overwritten; don't worry about it.)<br />
# Click on main.tex to see your main LaTeX document.<br />
# Press the "Recompile" button to see the pdf document that is compiled from the five 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.]]'''<br />
<br />
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>. The other three files are image files that get included in the document. You will create different image files depending on your exercise. For example, you can make a nice hand drawing and then scan it.<br />
<br />
To learn more about typesetting in LaTeX, google is your friend! Try googling "latex math" or "latex math symbols," for example.<br />
<br />
You will turn in the source for your exercise as a zip file, as well as the final pdf file.<br />
<br />
The final student assignments to topics is given below:<br />
<br />
[[File:StudentExercises2019.jpg|x400px]]<br />
<br />
==Assignments==<br />
<br />
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.<br />
<br />
'''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.'''<br />
<br />
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.<br />
<br />
'''Instructions for uploading assignments to Canvas:'''<br />
<br />
# '''Upload on time! Late submissions are not accepted under any circumstances. See the policy on dropping the lowest assignment grade under "Grading" above.''' The cutoff time is 30 minutes before class the day the assignment is due.<br />
# For every assignment, you should upload exactly one pdf file, named FamilyName_GivenName.pdf. This pdf file should have 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.<br />
# If required by the assignment (e.g., if you wrote code), in addition to the pdf file above, you should provide a zip file including all source code in their original forms, such as .m, .py, or .nb. This zip file should be named FamilyName_GivenName.zip. Always create a script (for example, titled exercise6-9) 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).<br />

<br />
==Final Project: Mobile Manipulation==<br />
<br />
The final project, described [http://hades.mech.northwestern.edu/index.php/Mobile_Manipulation_Capstone '''on this page'''], is due on Canvas at 1:30 PM Wednesday December 11 (finals week). Reminders:<br />
# Read and follow closely the instructions on what to submit! If you are missing requested files, or if you use a different directory structure, you will lose points. Make sure your top-level README file is clear on what you've done and what you've submitted.<br />
# If your code does not work well, please describe the remaining issues in your README file. Don't gloss over them or only provide examples where the code works well if the code does not work well for other example problems. Otherwise, if the graders find problems with your software, you will not receive credit for having identified them yourself.<br />
# You can get up to 10 pts of extra credit for correctly implementing joint-limit avoidance (so the robot links and chassis do not self-intersect) and singularity avoidance (e.g., using joint limits that keep the arm in a portion of its workspace where it does not encounter any singularities). If you implement these, it is best to submit examples of your code solving the same problem two ways---not using joint-limit avoidance and using it---so the usefulness of the joint-limit avoidance is apparent.<br />
# Make sure to keep your problem inputs separate from the code. The exact same code should solve all your problem instances; you shouldn't have different copies of your code for different problem inputs. You could have an input file for each of your examples (e.g., bestScript, overshootScript, newTaskScript) which defines the inputs (e.g., block configurations, controller gains, initial robot configuration) and invokes your code. Then a grader just needs to invoke those scripts to verify your results. (If you implemented joint-limit avoidance, this could just be one of your inputs, e.g., a variable called "avoidJointLimits" which is 0 if you don't care about avoiding joint limits and 1 if you do.)<br />
# Make sure your videos are good quality. They shouldn't be too fast (at least 5 seconds long) or low resolution. The motion should be smooth.<br />
# If your code is written in python, indicate which version of python should be used.<br />
# If you submit your code as part of the MR library, make it easy for the grader to find your code (e.g., collect it all in one place and indicate in the code or your README where to find it).<br />

:: 1) Exercise 3.1, except the y_a axis points in the direction (1,0,0).<br />
:: 2) Exercise 3.2, except p = (1,2,3).<br />
:: 3) Exercise 3.5.<br />
:: 4) Exercise 3.9. <br />
:: 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.<br />
:: 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).<br />
:: 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.<br />
:: 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'''!<br />
