Course information

Title CISC3xx Introduction to Mobile Robot Programming
Description A hands-on approach to implementing mobile robot algorithms on a small wheeled platform, both in simulation and reality. We will review the fundamentals of kinematics, planning, sensing, and control, as well as getting acquainted with higher-level concepts related to navigation, tracking, mapping, and learning.
When Wednesdays and Fridays, 8:40-9:55 am
Where Smith 102A
Instructor Christopher Rasmussen, 446 Smith Hall, cer@cis.udel.edu
Office hours Tuesdays and Thursdays, 11 am-12 pm (until October 15: in office; after October 15, in Smith 211)
Grading
  • 16% 3 assignments worth 16% each. Each homework will be due 2 weeks after being assigned.
  • 20% Presentation. 20-minute tutorial or demo of advanced features in ROS and/or PCL (that were not presented in lecture). You can talk about platforms (walking, flying), sensors, planners, perception algorithms, etc. using slides, images, and movies or live code.
  • 32% Project

Programming assignments will be graded on the basis of correctness, efficiency, and originality. This is not an introductory programming class, so coding style is not critical. However, if you want partial credit for something that doesn't quite work, it needs to be well-commented and easy to follow.

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 are due by midnight of the deadline 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 6 "late days" to use on homeworks to extend the deadline by one day each without penalty. No more than three late days 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 files, makefile, 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. The resulting file should be e-mailed to the instructor (cer@cis.udel.edu).

Students can discuss problems with one another in general terms, but must work independently on programming assignments. 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

Operating system
  • If you don't have a Linux distribution running currently, it's not hard to add one to your machine. The Ubuntu website has comprehensive instructions on installing it from different sources (CD-ROM, USB stick, etc.) on a separate partition (aka "dual booting"). I recommend version 12.04.
  • Other free options are VirtualBox and VMWare Player, which let you run Ubuntu from within Windows. I found these instructions helpful when setting up my virtual machine
  • Ubuntu can be run from within Mac OSX using VirtualBox or VMWare Fusion (which costs $50)
ROS
TurtleBot
Gazebo
  • The Gazebo 3-D simulator is included in the full desktop install of ROS
  • Wiki
  • Basic tutorials
  • ROSCon 2012 talk
  • To run "headless" (i.e. with no display), in launch file add -r to beginning of gazebo node's args string and comment out gazebo_gui node line
