New Software Stops Mars Rover Confusion

MattSparkes writes "The Mars rover Spirit used to get quite confused when it came upon a rock. Because it could only plan routes of a metre or two it couldn't understand how to navigate around large objects, and frequently used to rock back and forth for hours trying to figure it out. NASA have written new software called D* for the rover Opportunity, which should allow it to autonomously plan routes up to 50 metres long. The new software still won't be able to avoid sand-traps, though."

The Warcraft engine knows the dimensions of the rock... It's responsible for rendering it. The rover, however, knows only what it can see.

The slashdot moderation system is broken and penalizes humor in spite of the fact that the readership overwhelmingly supports it. Thus some people moderate using some other positive mod than funny, since funny does not give karma, but being modded funny and then being modded negatively does TAKE karma. HTH, HAND.

Thank you: Why can't New Scientist do this?

Thank you for letting us know and even providing a link to the tech report.

Here's one that that really bugs me about online news articles: they rarely take advantage of the medium! Why the hell couldn't New Scientist provide a link to this paper? As the parent mentioned, the very least they could have done would be to mention that it was related to A*. Yes, I realize that the "average reader" (whatever that means) may not want to know such details, but why couldn't they include a simple "(details...)" link right next to the mention of D*? An interested reader could click on the "details" link and expanded text would create a brand-new paragraph describing more details of the algorithm and providing a link to the tech report. Click again, and the detail paragraph collapses and you go back to reading the basic-version of the story. Simple!

These publishers haven't grasped the power of the new media. For them, online articles simply mean that it's faster, easier, and cheaper to publish stories. Basically, they embrace web publishing for their own selfish reasons. With just a modicum of thought, they could make their products much more valuable to the consumer. But I suppose that would require them to give a damn about their work.
