The AVC bot is coming together slowly. I am farther along than the blog posts would indicate because they lag the actual work by a few weeks. Even so I've simply not made enough progress.
To give myself a kick in the butt, I've invited some friends over to witness the maiden voyage (and/or catastrophic failure) of the AVC bot on Saturday, February 26.
Crap, I gotta get busy now!
I owe Sparkfun a video of the robot driving forward and turning left on its own but if that's all the robot can do on April 1, I'm screwed.
But, if I have that functionality in two weeks, that gives me several more weeks to refine and build upon it so I'll have a functional robot come April 23, competition day.
The path ahead to the maiden voyage:
- Port GPS NMEA parsing software to mbed
- Port data logging software to mbed
- Finish software for Kalman Filtering of gyro data
- Build "motherboard" for mbed MCU to interface with the goodies
- Implement 5V ADC to adapt IR rangers and gyro to 3.3V MCU
- Software to calculate bearing and distance to waypoint
- Software to manage the precise timing of sensor polling and navigation
- Software to adjust steering and speed based on actual vs. desired heading
