  • 01/04/22: An Overview of the course was discussed in class.

Course Text and References

ME/CDS/EE 234(a): The first quarter will use two main text books:

Course Syllabus

Theoretical Kinematics is the study of motion and the analytical tools to represent motion, while Applied Kinematics is the analysis and synthesis of mechanisms which implement given motions. This course presents a basic overview of theoretical kinematics, while the applied portions focus on robotic mechanisms.

An overview of the course, including course mechanics, grading, etc. The most salient information is repeated below.

Grading

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

  • Homework (70%): Homework sets will be handed out every 7-10 days, and 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 this course, 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.
  • Final exam/project (30%): Students have the option to take a final exam (a limited time take-home format exam which is open book, open note, and computer allowed) or select a final project. 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 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 solution, and therefore should be done individually (you can share ideas, but not code). No collaboration is allowed on the examinations.
