Weekly Report 7.18.06

This week I adjusted my motor control code in order to try to keep the robot from getting stuck in corners quite as often. I also created a test circuit for my RF and discovered that there is a change in the recieved voltage at the linear test line that is related to the distance that the device is away from the transmitter. The only issue is that there is a large amount of variation in how much voltage is recieved at any given point. After filtering it through a comparator, however, this system should be able to differentiate signal strength, on average.

I also fixed a problem that I was having with my power system. As I have added more systems, the current draw has increased. It was starting to cause serious problems with microprocessor resets. I installed new batteries that are capable of pushing a larger amount of current and this seems to have helped.

Finally, I found an LCD design that can fit (at least temporarily) on my robot for when I need to debug it and I wrote the code to get it to work.

Before the end of the week I hope to fully integrate RF and begin field testing some code involving it.
