I reworked the robot power system a little bit and made some software changes to try and fix the problems that I have been having with it. I ran the robot remotely for three days this week to test the changes. Bad news first: I have not completely eliminated the glitches. I had a couple of power failures this week requiring a reboot. Good news: It seems that the robot is significantly more stable than before. Even though I had a couple problems I was able to predict them by monitoring the power system, so I think that I will be able to handle it in the future. As a bonus, I have significantly reduced or eliminated some other glitches that plagued the original system. The loss of the serial/USB connection only occurred once this week where before it would occur 2-3 times per day. Also I have not any problems with the PowerPod. I want to give it another full week of testing before I draw any conclusions, but if this stability persists I will post another part to the robot project detailing the changes that were made.
