Course Information

Prerequisites

There are no formal prerequisites for the course. ME 115 ab (Introduction to Kinematics and Robotics) is recommended but not necessary. Students are expected to have basic understanding of linear algebra, probability and statistics. We will review some of the required background materials during the first week of lectures. Besides these, students should have some prior programming experience and know at least one of the following languages: C, Python, or MATLAB. Depending on the background of the class, we will hold tutorials for some of the programming languages to help students get started.

Grading

There are no midterm/final exams for this course. The grade will be based on weekly homework (60%) and two week-long labs (20% each). Late homework will not be accepted without a letter from the health center or the Dean. However, you are granted a grace period of five late days throughout the entire term for weekly homework. Please email the TAs and indicate the number of late days you have used on the homework. No grace period is allowed for week-long labs.

  • Homework: Homework is usually due in one week after it is assigned. You can choose to turn in a hard copy in class or send an electronic copy to Andrea Censi (andrea at cds.caltech.edu). If you are unable attend the lecture, contact the TAs to find an alternative way to turn in your homework.
  • Labs: Students will form groups of 2-3 people and perform lab experiments together. Detail of this will be announced later in the course.

Collaboration Policy

Students are encouraged to discuss and collaborate with others on the homework. However, you should write your own solution to show your own understanding of the material. You should not copy other people's solution or code as part of your solution. You are allowed to consult the instructors, the TAs, and/or other students. Outside reference materials can be used except for solutions from prior years or similar courses taught at other universities. Outside materials must be cited if used.

Course Texts

There are two required textbooks, both of which are freely available online:

Other optional reference materials (books are on reserve at SFL):

  • David A. Forsyth and Jean Ponce, Computer Vision: A Modern Approach, Prentice Hall, 2003.
  • Sebastian Thrun, Wolfram Burgard, and Dieter Fox, Probabilistic robotics, MIT Press, 2005.

Homework

Homework 1 (Due: 2:30pm, 18 Jan)

  • FAQ, Solution
  • You will need Chapter 1 from Forsyth's book, which is available here (Caltech/JPL access only).

Homework 2 (Due: 2:30pm, 3 Feb)

Lab Assignment 1 (Due: 2:30pm, 15 Feb. No grace period is allowed).

  • FAQ, Solution
  • You will need the data in this file. The lab assignment is divided into two components:
    • C/C++ component (lab01_material/part1/)
      • The folder contains the tutorial client code, reference/test images, and Player/Stage config files.
      • Be sure to sign up for a course server account if you haven't.
      • Refer to the exercises on this page to learn how to use Player/Stage.
    • MATLAB component (lab01_material/part2/)
      • The folder contains the feature datasets for RANSAC/homography, the Matlab SIFT feature extraction code, the object images, and the test sensor data.

Homework 3 (Due: 2:30pm, 22 Feb)

Lab Assignment 2 (preview) (Due: 5:00pm, 10 Mar. No grace period is allowed).

  • Note that this is only a preview. The final version may look different and contain more instructions, but should be very close to this.
  • The lab assignment is divided into two parts. Each group should prepare for a single lab report.
    • Part I: Data Association for SLAM
    • Part II: EKF Localization
      • You will need a dataset containing the sensor measurements, landmark locations, etc. We are still in the process of preparing it and will provide it as soon as possible.
