ROB 101: Computational Linear Algebra

We suggest you select the in-person section if you are planning to be in Ann Arbor. If you are not planning to be in Ann Arbor, then we suggest the distance learning section. You will have the same access to office hours, help sessions, HW sets, projects, etc. The grading will be the same. There is no bonus for attending lectures or labs.

If you signup for the in-person section, then you can always chose to watch the live Zoom simulcast and the recording of the live lecture. If you signup for the remote section, and you want to occasionally drop into the classroom for the live lecture, that is fine too, as long as there is an open seat. We want you to learn in the way that works best for you.

Engineering math education is stuck in the Sputnik era: we force you to do four semesters of calculus before you can do anything interesting in engineering. ROB 101 seeks to break through with new ideas. You will see how engineers are using mathematics and computing to solve large and important problems. You will still do drill problems to firm up concepts with teeny tiny problems with two or three variables, but you will also solve problems in the Julia programming language with hundreds of variables.

Instead of seeing the “rules of calculus” as your introduction to college mathematics, you will experience the “raison d’etre of mathematics in engineering”, in other words, why we employ it so heavily in engineering in the first place. And instead of starting mathematics by learning the innumerable ways to get a closed-form expression by a change of variable in an integral, you will learn how to formulate and perform relevant computations with algorithms. In short, you will have a palpable understanding that computation and mathematics are your friends instead of hoops to be jumped through on the way to a degree.

Yes. You check to check a box on Wolverine Access to allow you to do that. You can then enroll in the remote section of ROB 101.

No. Wolverine Access does not offer that flexibility. The in-person section of the labs will be relatively lightly attended. It will be easy to drop into them in person. Hence, choose your modality based on the lecture.

No. Labs are not graded. They are designed to make the HW easier. HW is graded. Everything in ROB 101 is done to assist your learning of the material.

We assume no prior knowledge of Linear Algebra or programming. We assume that you have completed a high school Algebra course where you learned how to solve quadratic equations. That is it.

You have been admitted to U-M Engineering — that tells us that you are up for a challenge! You’re smart, and you want to become a good engineer. We also need you to be a person who respects others and demonstrates humility. The field of Robotics is so broad that no one person can master even ⅓ of the subject.

The first thing we teach our graduate students is to say the words: “Can you help me with this?” In Robotics, asking for help is not a sign of weakness. It is a sign that you respect and appreciate a fellow human being. If you cannot bring yourself to ask for help, then you’re probably not the right person for ROB 101.

You need to be able to access the web. The course will use the Julia programming language delivered to you in the form of Jupyter notebooks that can be run in a web browser. If you can access the U-M course learning site, Canvas, then you can access all of the course materials and turn in all of the homework assignments and projects.

Based on the Course Evaluations, we are adding a one-hour weekly lecture on the Julia programming language. Formally, it is listed as a lab. However, you can attend the lab in person or live streamed, or even watch a recording of the programming lecture. The lab is listed as two hours. The additional hour will be a “Recitation Period”…meaning an hour where a GSI works out example problems and takes questions live, with it being also live streamed on Zoom and recorded. The recitation is optional. In fact, we do not take roll in lecture, lab, or recitation. You get to choose the best modality for your style of learning.

No. The class is being offered in hybrid mode: your instructors will lecture in a classroom to anyone who wishes to attend. The lecture will be simultaneously broadcast on Zoom and recorded. The recorded lectures will be posted on the ROB 101 Canvas site. A student instructor will help the faculty member to monitor the chatbox on Zoom. You will be encouraged to participate. We’ll have anonymous means to ask your opinions about stuff.

All quizzes, HW sets, and projects will be conducted in electronic form. There will be a window of time during which they can be completed. ROB 101 will be much different than a typical college course: we are not planning on two midterms and a final exam. We are planning on course projects to be where you demonstrate your ability to synthesize information. The quizzes are “open book” and un-timed; they encourage you to review material.

Remote vs In-person: The course was being designed for hybrid delivery (in-person + remote) even before the pandemic struck in March 2020. Based on our experience during Fall-20, we expect our remote students and in-person students to have similar outcomes with the course material. You are free to attend sometimes in person and other times to be remote. We do not take roll! Please choose the section that reflects your current best guess of how you want to experience the lectures and the laboratory.

ROB 101 is intended to fulfill the linear algebra prerequisite of many courses in Engineering, with specific attention to more streamlined preparation for Robotics and AI courses. As it is a new course, we are still working to have ROB 101 recognized throughout the College, and specific credit requirements that it fulfills is still undetermined.

However, CSE now does accept ROB 101 in place of MATH 214 and 217 for many courses (see prerequisites here).

We expect to admit 100 students. Preference will be given to Y1 students (freshmen). We are currently looking into options to significantly expand the online section of the course–provided we can hire adequate teaching support for expanded enrollment.

We recommend joining the waitlist for the online section, as we are more likely to be able to expand this section. You can sign up for the course waitlist using these instructions.

Roughly speaking, it’s a branch of mathematics that deals with linear equations in several variables. It also includes a number of tools, such as vectors, matrices, spaces of vectors, and linear transformations.

It has become the language of computer vision, machine learning, robotics, and autonomy. It provides very compact and insightful ways to manipulate information. Linear Algebra and programming go together like hand and glove.

Robotics and many other fields are supporting open-source tools of all kinds. When researchers submit papers nowadays, they are expected to share software that supports the mathematical and experimental concepts in the paper. In the past, many researchers indeed used MATLAB. While it’s a great programming environment, it’s also very expensive. Also, you must have a local copy on your computer in order to use it. Julia, on the other hand, is open-source software and we can deliver it to you via a browser. This provides near-universal accessibility.

The programming structures in Julia and MATLAB are very similar. It will probably take you two weeks to get up to speed in MATLAB once you learn Julia. In addition, learning Julia will help your acquisition of C++.

It’s a new language. The help pages are not as beautifully organized as the help pages for MATLAB. You’ll learn to google a lot as you acquire skills in Julia.

Your instructors believe that linear algebra is easier to learn than calculus and they 100% know that it is much easier to begin doing meaningful things in engineering with Linear Algebra than it is with Calculus. We’ll do three projects in the course. In the first one, we’ll have you building a map that a robot could use to navigate on the North Campus Grove.

That is a very good question! A number of us have been advocating for it for a long time. The Robotics faculty at Michigan, led by Professor Chad Jenkins, finally decided to do something about it. Normally, mathematics courses are developed through the Department of Mathematics. We want you to see how engineers use math and think about math. Other schools are starting to do this as well. Professor Steven Boyd has introduced a Linear Algebra course at Stanford that is required for first-year engineering students. Will ROB 101 be a required course at Michigan someday? Hard to say! We have to survive the pilot offering first.

It is fine to follow the course asynchronously, which means you watch the recorded lectures/labs at a time of your choosing. You are not required to attend in person.

We plan for the course to meet in person in the new Robotics Building on North Campus. But again, attendance in person is a personal choice. No one is obliged to attend in person.
