Well, I decided to take the plunge and enter this contest with only one month until the competition... Here is a link to the information site.

This is a NASA sponsored contest to create a machine that can excavate lunar soil to be processed, one process being removing breathable oxygen from the soil.

One key reason that I decided to enter is that the competition takes place about 15 miles from my house; I couldn't pass up the opportunity! It doesn't hurt to have a total purse of $250,000 available, but in reality, the most value will be from all of the people that I will meet at that time.

This particular challenge involves moving simulated lunar soil from a 4 meter square sandbox into a 1 meter square collection box. The machine that moves the most material, over 150kg, wins first place. Oh yea, did I mention that you get 30 watts of power for 30 minutes to do this?

I don't want to say much yet about my design approach, but I will say that I have a prototype machine that already digs pretty well, and there is plenty of time to work out the details.

More later...
