Revision as of 14:42, 26 October 2016

Fall Quarter 2016

Course Summary

Mechanics of robotic manipulation, computer representations and algorithms for manipulation planning, and applications to industrial automation, parts feeding, grasping, fixturing, and assembly.

Grading

Grading for the course will be based on problem sets and a final project. There will be no exams.

Course Text and Software

You can find the latest version of the book, and the software, by clicking here. You can also submit your corrections.

Introduction to V-REP, which we will be using to simulate robots.

How to obtain MATLAB.

Reading

This supersedes the approximate syllabus below.

  • Chapter 2
  • Chapter 3
  • Chapter 4 (4.2 can be skimmed)
  • Chapter 5
  • Chapter 6 (6.1 can be skipped)
  • Chapter 8 (8.4 can be skipped; 8.6-8.9 are for reference only for those interested)

Assignments

Assignments are graded based on correctness, how well you organize your homework (it should be easy to understand your thinking and easy to find your responses), and how well you follow the submission instructions below. You will lose points if you don't follow these instructions.

If you ever think a problem is stated incorrectly, not enough information is given, or it is impossible to solve, don't panic! Simply make a reasonable assumption that will allow you to solve the problem (but clearly state what this assumption is), or indicate why it is not possible to solve the problem.

Instructions for uploading assignments to Canvas:

0. Upload on time! Late submissions are not accepted. The cutoff time is at the beginning of class on the day the assignment is due.

1. Only upload one zip file or rar file for each assignment;

2. In your zip file or rar file, include all source codes in their original form, such as .cpp, .m, .py, .nb.

3. If there is a demo, combine the screen shots into one SEPARATE pdf file, OR, show the results in one SEPARATE .txt file (DON'T show them in your source code file format, e.g. .nb file), and include it in the zip file (or rar file).

4. Please name the codes by their corresponding problem numbers.

5. Please name the upload file in the following format: LastName_FirstName.zip.

Assignments

  • Assignment 1, due on Canvas before the beginning of class on Thurs Oct 6: Chapter 2, Exercises 1, 3, 5, 16, 17, 28, 29; Chapter 3, Exercises 1, 2, 6, 16, 26, 27, 28, 31, 47.
  • Assignment 2, due on Canvas before the beginning of class on Thurs Oct 20: Chapter 4, Exercises 1, 2, and 7; Chapter 5, Exercises 2, 3, 8, 24, 25, and 28
