Meet the Drivers Behind NASA's Mars Rovers

StonyandCher writes "Scott Maxwell must have one of the best IT jobs in the solar system, driving NASA's Mars Rovers. Behind every robot is a driver. He's one of 14 Rover Drivers that work in NASA's California-based Jet Propulsion Laboratory. Maxwell discusses what makes up an average work day, the highlights of the project, how he got the job, and the tools he uses in his work. A great look at the team of dedicated IT workers behind the robots, plotting the every move of NASA's twin robot geologists, Spirit and Opportunity, since they first landed on Mars at the start of 2004."

Engineers fixed the problem by writing software to operate the tool without data from the encoder.

      Spirit's rock grinder's diamond heads were all worn out I thought last year. Thus, I thought it could no longer grind at all, only use the rotating brush on rocks. Maybe they mean they applied the same fix to the brush.

ATHLETE and MSL are awfully cool rovers, but even so, I miss the days when I worked full-time on MER.)
