Once again, I've left it far too long since I last posted. However, I hope I can summarise what I've done in the past month or so without making it insanely long.

Progress
So, once again, it's been about a week since I posted, and plenty has happened for me to comment on! I've spent a fair amount of time mentally arguing with myself about various things, but I've actually done some work, too.

Catch-up: Software and PCB Production
I must apologise to any readers I may have, as well as myself, for letting the blog slip for two weeks. I've mostly been working on software, but have been doing some PCB-related stuff too, and I didn't think there was much worthy of commenting on for now. Anyway, here's what's been going on for the past two weeks...

Finalising the Hardware and Designing a PCB
I've been working towards the inevitable PCB production stage, making decisions and testing designs to allow a PCB to be designed sensibly. Designing a PCB takes quite a lot of time to do properly, and learning to use the software effectively can take a little time.

A Lazy Friday
Some days feel a bit slow, and you don't get much work done. The work you do get done, though, feels well worth it. Today I tested out the serial interface, and produced a test pattern which should be useful for testing the floor sensors.

Motor Feedback and Hardware Design
Today I tested whether low-pass filtering of the current sense signals from the motors was of any use, and investigated some methods of getting motor speed feedback. I also considered the use of the AVR's pins, and looked into obstacle detection and mapping hardware.

Considering Requirements
I started the day by researching more about FreeRTOS, specifically the differences between tasks and coroutines. I then went on to explore whether FreeRTOS would be the best option for the robot, or whether I could make do with a simpler multi-tasking system.
