"Part-Time" Scientists Aim To Build Autonomous Moon Rover

First time accepted submitter ziegenberg writes "The lunar rover 'Asimov' developed by the Part-Time Scientists, and due to land in 2014, will be the first autonomously navigated rover on the Moon. Its autonomous navigation system is a major technological leap. While the Russian Moon rovers Lunokhod 1 and 2 in the early 70s were fully controlled from Earth, today's Mars rovers like NASA's Mars Exploration Rover 'Opportunity,' which has been tirelessly exploring the Red Planet since 2004, are autonomous. However, Opportunity requires nearly three minutes to process a pair of images — a delay that causes it to move at an average speed of just 1 cm/sec or less. New developments by the technology partnership between the DLR Institute of Robotics and Mechatronics and the PTS have created, for the first time, an autonomous navigation system for a rover that has the capacity to process multiple images per second. The technology boosts a stereo camera that Asimov will use to calculate its own motion, generate a 2.5-dimensional environmental model, evaluate the site and determine a collision-free path — all in real time."

GPUs continue to take off ( this time literally )

[boshi]

It seems like every month now that I wake up in the morning and see another amazing application for GPUs. It is incredible to see the progress that a multi-billion dollar entertainment industry can bring to other markets like space exploration that would normally run on super expensive first-generation prototype hardware.

"Avg speed of 1 cm/sec" and a question

[c0lo]

Opportunity (the rover) has a ration of 560 W*h/day for everything it needs to do - and this includes moving its 180 kg.

Granted, the insolation will be better on the Moon than on Mars (closer to the Sun), but... just how much power their GPU is going to require for computing the 2.5 D env data?

The main problem with Spirit and Opportunity was that there were extreme limitations on size and mass. Thus the unusual and innovative method of a "beachball" landing... which given the restrictions made the whole thing possible. Other means such as retro-rockets, as with the current mission, simply were not physically possible given those conditions, and that was calculated in the very beginning. Thus the unusual -- one might say -- "alternative" -- landing method. It maximized the amount of scientific instruments that the rovers could carry.

Due to the size and mass restrictions, nuclear power was also not an option, and the size of the solar arrays was necessarily limited. Nevertheless, while I know you are not criticizing the two rovers, it must be stated: given the constraints under which they had to operate, they worked remarkably well, and lasted years beyond their planned 90-day lifespan. If ever there was a NASA success, Spirit and Opportunity are it.

The moon also has a rather longer day - a lunar rover running solar would have to operate for fifteen days of sun, then hibernate for fifteen days of darkness. And the occasional eclipse. With that and the lack of an atmosphere, solar power isn't going to be an issue. More concerning is the task of keeping it from melting after fifteen days of intense solar radiation and no atmospheric cooling.

But the moon surface is rock stable.

I guess you've never heard of moon quakes. Rock stable my ass. Consider this the new thing you learned today.

Woosh!
