Course Text and References

The main course text for ME/CS 133(a) is:

We will refer to this text as MLS (the initials of the authors' last names). While the course topics will follow the text, additional material will often be presented in class. Additional course handouts covering this material will be posted on this website

A main text for the ME/CS 133(b) is: Planning Algorithms by Steve LaValle (UIUC).

The following book is recommended (but not required) for ME/CS 133(b):

  • Principles of Robot Motion: Theory, Algorithms, and Implementations, by Howie Choset, Kevin Lynch, Seth Hutchinson, George Kantor, Wolfram Burgard, Lydia Kavraki, and Sebastian Thrun.

This text is available at Amazon in both new and used versions.

Grading

The final grade will be based on homework sets, and a final exam or final project:

  • Homework (35%): Homework sets are due at 5 pm on the due date (which will always coincide with a class meeting). Homeworks can be dropped off in class, or deposited in the box outside of 245 Gates-Thomas. Some homeworks will require computation. MATLAB or Mathematica should be sufficient to solve every homework posed in ME/CS 133(a), though students can choose their favorite programming language. Code is considered part of your solution and should be included in with the problem set when appropriate.
  • Laboratory (30%): Lab reports are due at 5 pm on the due date (which will usually coincide with a class meeting). Labs can be dropped off in class, or deposited in the box outside of 245 Gates-Thomas. The first labs will familiarize students with the class robots. Subsequent labs will focus on how to translate the lecture material to the lab robots, and will often involve the use of software systems such as ROS and OOMPL.
  • Final project (35%): The final project must incorporate some aspect of the course, and the topic and scope my be approved by the course instructor. The final exam will due at 5:00 pm the last day of finals. The final project is similarly due at 5:00 pm on the last day of finals.
  • Late Homework Policy: Students may automatically take a 2-day extension on two homeworks or labs during each quarter.

Collaboration Policy

Collaboration on homework assignments is encouraged. You may consult outside reference materials, other students, the TA, or the instructor, but you must cite any use of material from outside references. All solutions that are handed in should be written up individually and should reflect your own understanding of the subject matter. Computer code and graphical plots are considered part of your homework solution, and therefore should be done individually (you can share ideas, but not code).

Laboratory assignments will be performed in small teams. Collaboration on laboratory assignments is different. Each team need only submit one laboratory report.
