NASA Testing Linux-Based Exploration Robots

SeenOnSlash.com writes "This week NASA is testing a Linux-based lunar rover called K-10 in the Arizona desert. To cut costs and promote maintainability the K-10 runs Linux and uses commercial off-the-shelf parts where possible. The robot rover's control and communications system is based on an IBM Thinkpad X31 and attaches to subsystems with standard PC interfaces. Real-time tasks such as fine-grained motor control are offloaded to a distributed network of microcontroller-powered control boards. Maneuvers can be watched through a live webcam."

Re:A great Contest

The use of Linux and commercial grade gear for the space program is really quite cool stuff. It makes me think that a really cool contest for NASA would be to have grad students desgn and build a rover/probe and the winner (once vetted by NASA) is actually launched into space. It is probably cost prohibitive but it would be very cool if it happened. It may be a way to break NASA groupthink, and re0invigorate designs with some fresh minds. Not that I'm critisizing NASAs robotics programs, the Mars rovers are a smashing success.

I suspect that the idea here is to cut down development costs, not the build costs for the final implementation. Commercial grade gear just wouldn't cut in space with the extrem temperature swings, cosmic radiation messing with memory or if you end up on Venus god knows what kind of weird atmosphere.

But someone could actually build a proof of concept design (like they're doing now) that could become the basis for the actual rover. I can't imagine it takes that much more work using Linux than some other solution since there's bound to be a lot of non-standard stuff going on with the rover software.
