=== Mechanical Design & Issues ===

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 Design & Issues ===

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.

'''Laptop Software'''

Under Construction - To add a how-to for using the GUI, descriptions of the files, and additional software development tools.

OS:
The IGVC laptop is running Debian Linux kernel v.2.6.8.1. The KDE v.3.3 desktop environment is also running on the machine.

GUI:
To activate the GUI, open a UNIX terminal, navitage to laptop_svn, and type ./IGVC.

How-Tos:
#[[Capture video data through IEEE 1394]]

=== Software Design & Issues ===

Most of the code this year was written by [[User:BenJ|Ben]], [[User:DavidF|David]], or [[User:SpencerC|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 [http://subversion.tigris.org/ SVN] repository:

'''URL:''' <tt>svn://130.207.76.145/igvc</tt> 
'''Username/Password:''' Talk to [[User:DavidF|David]], [[User:SpencerC|Spencer]], or [[User:MichaelG|Michael]] to get one.

Though the team was well-prepared going into 2019 IGVC, several issues came up during competition. On the first day, the mbed was experiencing issues and causing the computer to brownout. The mbed was fried while attempts were being made to fix the problem. Eventually this was solved with a new mbed and a large capacitor, which prevented brownouts from happening, though the whole process of fixing the robot took up the first day of the competition. During the second day, major progress was made; the team was 4th to qualify, which was the earliest Georgia Tech has ever qualified in IGVC. Additionally, the robot had a few successful runs on the course. Most notably, the great backwards run tragedy of 2019 happened. During this run, the robot turned itself around and went BACKWARDS on the course, though it went extremely far. This ended up being (absolute-value) the second longest run achieved by any robot in the competition this year, though it didn't count towards our score since it was backwards.

-----

=== Mechanical Design & Improvements ===
We tried to make Jessii a more modular and accessible version of Jessi.

-----

=== Electrical Design & Improvements ===
For Jessii, the electrical team focused on iterating on several components of Jessi's system to improve weaknesses seen at the prior competition.
*Custom Computer and Improved Sensors
**To improve computational capabilities and performance we upgraded our computer and other sensors
***Intel i7-8700K 3.7GHz 6 Core Processor, Nvidia GTX 1060 GPU, 32GB RAM
****GPU was chosen for CUDA support
****Hotswap capability was brought using a PCB though not implemented before competition
***Velodyne Puck VLP-16 3D LiDAR
***YostLabs 3-Space Micro USB IMU
*E-Stop
**E-Stop circuitry was consolidated onto E-Stop PCB
**Relay was used instead of a transistor used in version 1.0
*Ethernet Communication Protocol
**The logic board, the custom PCB which handles motor control switched from a virtual serial interface from MBed to a custom Ethernet communication protocol for robustness

-----

=== Software Issues & Improvements ===
We faced a few issues this year:
* Robustness of line detection
** We moved from a pretrained FCN8 to a U-net architecture that didn't have pretraining. As a result, on the final day, our neural net had a decent amount of false negatives.
* Computational efficiency of global path planning
** We used the Field D* for global path planning. However, it wasn't computationally efficient, and failed to find a path in a reasonable amount of time at the beginning of the run, when it saw lines that extended a fair distance in front.
* Because we were seeing lines in front and not behind us and the first waypoint was located to the side of the starting location, the global path planner planned a path that went behind us, leading to the famous reverse run.
