Course Outcomes

Students will have:

  1. A "toolbox" of prominent algorithms for implementing intelligent, autonomous robot behaviors.
  2. Ability to derive kinematic models for wheeled vehicles.
  3. An understanding of common sensor systems used in mobile robotics.
  4. An understanding of basic image processing operations such as convolution, color segmentation and edge detection.
  5. Ability to implement Bayesian filters (Kalman and Particle) for estimation.
  6. An understanding of basic motion planning and control techniques for mobile robots.
  7. Laboratory experience processing data from LIDAR sensor systems.
  8. Laboratory experience working with the iRobot Create robot research platform.
  9. Ability to develop near real-time applications under Matlab.
  10. Work in teams to complete the robotics laboratory exercises, and complete the Robotics Grand Challenge final project.

Relationship between Course Outcomes and Program Outcomes:

CSE 360 substantially supports the following program outcomes:

  • An ability to apply knowledge of computing and mathematics appropriate to the discipline
  • An ability to design, implement, and evaluate a computer-based system
  •  An ability to apply mathematical foundations, algorithmic principles, and computer science theory in the modeling and design of computer-based systems in a way that demonstrates comprehension of the tradeoffs involved in design choices.

CSE 360 provides modest support to the following program outcomes:

  • An ability to function effectively on teams to accomplish a common goal
  • An ability to use current techniques, skills, and tools necessary for computing practices
  • An ability to apply design and development principles in the constructions of software systems of varying complexity.

Prerequisites by Topic:

  • Programming course in an imperative programming language
  • Matrix operations
  • Calculus and linear algebra operations to include mathematics on matrices, eigen value/vector decomposition, Taylor series, gradient, etc.
  • Basic probability concepts

Major Topics Covered in the Course

  • RANSAC
  • Hough Transform
  • Kalman Filters
  • Particle Filters
  • Feedback Control
  • Motion Planning

Assessment Plan for the Course

The students are given three laboratory assignments, five or six fairly long homework assignments, and a final project. Each homework assignment typically covers a single topic, but the laboratory assignments build upon these allowing the students to implement increasingly complex behaviors on the robot platform over the course of the semester. The course culminates in a final project where the students program a robot to navigate a road network without hitting any obstacles while reaching a goal position. This has the potential to implement many of the topics covered throughout the course. I track the performance of the students on each homework and laboratory assignment, and perform an "out briefing" with each team on the final project to discuss their strategy, what worked, what didn't, and recommendations for how to improve the course.

How Data in the Course are Used to Assess Program Outcomes: (unless adequatley covered already in the assessment discussion under Criterion 4)

Each year, I use the above data from the assessment plan for the course in my self-assessment of the course. This report is reviewed, in turn, by the Curriculum Committee.
