Mechanical Issues & Improvements
Electrical Issues & Improvements
Needs correction:
- GPS communicates over COM2(/dev/ttyS1)
- Time server (NTP) runs on the TS board reading the Data Carrier Detect (DCD) line of COM2
- Add: TS Board is running an NTP server to define robot time
- Software modules should be included
- Rename "Arduino" -> "Motor Arduino"
- Add "Power Arduino"
- Fix: Wheel Encoders will be communicating over SPI
Software Issues & Improvements
Our code for this year is stored in Subversion and is accessible at https://svn.robojackets.org/igvc/2008. The laptop codebase will be written in C++.
Contributers to the laptop codebase should ensure that they are following our coding conventions.
Player/Stage:
We are using the Player/Stage robot server as the communication layer between our device drivers and our processing/controlling software modules.
As we've used the Player server, occasionally we've needed to patch it to better suit our needs. Below are our custom patches:
Candiii (V3.0)
At Competition
Mechanical Issues & Improvements
Candiii's body has remained essentially the same for the last 2 years.
Electrical Issues & Improvements
Candiii has two isolated power systems: one for the motors and one for the other electronics.
Other Electronics:
- Camera
- LIDAR
- IMU
- GPS
- Compass
- Motor encoders
- Motor currents
Software Issues & Improvements
Localization and Mapping:
Controls:
- PI-Lead control(?)
- Joystick
