Revision as of 12:32, 23 October 2015

Fall Quarter 2015

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

"Introduction to Robotics: Mechanics, Planning, and Control," F. C. Park and K. M. Lynch. These course notes will be undergoing revision throughout the quarter; check the timestamp in the table of contents.

Summary of important equations.

How to obtain Matlab

Assignments

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 each zip file or rar file, include all source codes in their original form, such as .cpp, .m, .py, .nb. It will make our life much easier if the files are in their original format, instead of a pdf version of all codes;

3. If there is a demo test, combine the screen shots into one pdf 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.

Visualizing Manipulators in MATLAB or ROS

We provide two different methods for visualizing the motion of a robotic arm, one in MATLAB and the other in ROS. Choose whichever method sounds more appealing to you.

The Robotics Toolbox for MATLAB

If you would like to use MATLAB, we recommend the Robotics Toolbox for MATLAB. Please download the version we provide on the ME 449 wiki. We've made a minor change to the original code, so that the base and end-effector frames are shown by default. Instructions on how to visualize poses and animate arm trajectories can be found here and in the zip file below.

Download: MATLAB Robotics Toolbox for ME 449.zip.

ROS/rviz

If you would like to use rviz, a visualization package in ROS (Robot Operating System), we provide installation and usage instructions for native Linux users and a virtual machine for Windows and Mac users.

Linux users, follow these instructions: Kinematics Tool Guide for Native ROS on Linux.

Windows and Mac users, you should follow these instructions: Kinematics Tool Guide in a Virtual Machine (Mac, Windows).
