So, the project has been on hiatus for a few months. This was due to a number of factors that all coincided at the same time.
RedPeasant ended up taking an extended trip, so he was unavailable to work on the robot for a couple of months. Then, I bought a house, and had to move all my stuff. All of this together has meant that there has been virtually no progress on the robot in the last three months. Hopefully, that will be changing shortly. I've gotten the shop at the new location set up, and we should be able to resume work within the next month or so.
This project is not dead, really!
