Revision as of 15:17, 28 November 2023
Course information
| Title | CISC849-015 Robot Navigation and Autonomy |
| Description | A hands-on approach to implementing mobile robot algorithms on a small wheeled platform, both in simulation and reality. We will focus on image- and depth-based sensing algorithms for obstacle segmentation, object recognition, and motion planning, including deep learning techniques in these areas. |
| When | Tuesdays and Thursdays, 2:20-3:40 pm. When there is a homework due, no more than the first 30 minutes of each class will be in lecture format. The rest of the class period (and optionally the subsequent office hours) will be spent working on the robots. |
| Where | Smith 211 |
| Instructor | Christopher Rasmussen, 446 Smith Hall, cer@cis.udel.edu |
| Office hours | Tuesdays and Thursdays, 3:40-5 pm in Smith 211 (starting Aug. 31) |
| Grading |
Programming assignments will be graded on how many of the subtasks you complete or demonstrate successfully. For the overall course grade, a preliminary absolute mark will be assigned to each student based on the percentage of the total possible points they earn according to the standard formula: A = 90-100, B = 80-90, C = 70-80, etc., with +'s and -'s given for the upper and lower third of each range, respectively. Based on the distribution of preliminary grades for all students (i.e., "the curve"), the instructor may increase these grades monotonically to calculate final grades. This means that your final grade can't be lower than your preliminary grade, and your final grade won't be higher than that of anyone who had a higher preliminary grade. I will try to keep you informed about your standing throughout the semester. If you have any questions about grading or expectations at any time, please feel free to ask me. |
| Academic policies | Programming projects should be demo'd in class on the deadline day and uploaded to Canvas by midnight of that day (with a grace period of a few hours afterward...after sunrise is definitely late). A late homework is a 0 without a valid prior excuse. To give you a little flexibility, you have 3 "late days" to use on homeworks to extend the deadline to the next class period without penalty. No more than one late day may be used per assignment. Late days will automatically be subtracted, but as a courtesy please notify the instructor in an e-mail of your intention to use late days before the deadline.
Assignment submissions should consist of a directory containing all code (your .cpp/.py files, etc.), any output data generated (e.g., images, movies, etc.), and an explanation of your approach, what worked and didn't work, etc. contained in a separate text or HTML file. Do not submit executables or .o files, please! The directory you submit for each assignment should be packaged by tar'ing and gzip'ing it or just zip'ing it. Students can discuss problems with one another in general terms, but must work independently or within their teams as specified for each assignment. This also applies to online and printed resources: you may consult them as references (as long as you cite them), but the words and source code you turn in must be yours alone. The University's policies on academic dishonesty are set forth in the student code of conduct here. |
Instructions/Resources
| Robot |
Yes, our robot platform is a Roomba. Except it can't clean.
|
| ROS |
We are using ROS2, to be exact, and the Humble Hawksbill version. My laptop and the Raspberry Pi's on the robots are running Ubuntu Desktop 22.04 LTS, and I strongly recommend that you do the same. I say this not because of convenience, but after hard experience last semester with another group of students. Trying to install and run ROS2 on Windows or MacOS natively is a recipe for frustration and disappointment. Here are installation instructions for Ubuntu. Several students with MacOS had success using Ubuntu in a VM such as UTM. With a VM there are more issues such as setting up bridging mode for wifi, but it's workable. A lot of public sample code and tutorials are available in both C++ and Python, but expect mostly C++ examples from me. I am agnostic about which of these two languages you use for homeworks and projects, but you will get your best support from me in C++. |
