Mars Rovers and you

Recently, I posted blog comparing the computers used for the Apollo moon missions to an Arduino.  The Apollo Guidance Computer (AGC) was considerably less powerful than an Arduino.  Continuing along that line, I started investigating other computers used for space exploration.  Since the mars rovers are popular among robot builders, and often the source of inspiration and goals, I decided to take a look at those.  The results are rather interesting.
