Mechanical Issues & Improvements

Trixxie is a basic cube-shaped robot with two motors mounted on the front. The base has three layers in ascending order: a level for holding Trixxie's heavy batteries, a mid level for holding electronics and the laptop, and a top level on which a payload may sit.

Electrical Issues & Improvements

The electronic hardware of the IGVC robot is built around a central laptop. The laptop provides a central processing unit for all data aquired from the modules.

How-to

1. Capture video data through IEEE 1394

Software Issues & Improvements

Most of the code this year was written by Ben, David, or Spencer. Much of this code was also inherited from the 2004-2005 year. There are notes on that code here: File:Notes on Ben's Code.pdf.

The code is stored in an SVN repository:

URL: svn://130.207.76.145/igvc
Username/Password: Talk to David, Spencer, or Michael to get one.

The following image sequences were taken on 10/08/2005 as test footage for creating vision algorithms.

1. IGVCclip1.zip - IGVCclip1movie.mov
2. IGVCclip2.zip - IGVCclip2movie.mov
3. IGVCclip3.zip - IGVCclip3movie.mov
4. IGVCclip4.zip - IGVCclip4movie.mov
5. IGVCclip5.zip - IGVCclip5movie.mov
6. IGVCclip6.zip - IGVCclip6movie.mov

Animations were assembled and uploaded by David, using the ConcatenateMovieSegments program.
