Re: NASA does it again

Indeed, Ann, I think this may also have to do with some of the budget concerns NASA has had. Always a bastion of R&D, the agency now has to do more with less. So perhaps it's far better for them to specialize for specific tasks in their robotics research since they don't have the luxury of R&D for R&D's sake anymore. I will check out that slideshow! Partnering up seems to also be a good tactic to keep NASA R&D alive and as innovative as it's always been.

Ahan Nasa is doing great work , But i have one question this Robot would have been created for a specific surface level and what i think is that over their its not necessary that all the area has the same surface i mean to say the size of the sand granulaes and pebbles may varry as well as this is a nature and nothing cant be constant .So what have they done in order to over come this issue as the robot can stuck as well because of large pebbels .

Of course then we could have a reclamation project for the moon like all the major earth-bound mines have (at least in the US).  We could send our un-recyclables back to even our the mass changes.

Good idea. Time to strip-mine the moon and fire bolts of ore back to the Earth.

Let's say we mine a trillion tons of ore from the moon and asteroids, adding the Earth's mass. Would that eventually slow the momentum, orbit, etc of the planet? I would imagine, since we would add more mass than there would ever be on the planet in our lifetime. (barring a major collision.)

Ann, I wonder if this machine is a precursor to mining projects. If we find sufficient valuable metals and elements on the Moon or Mars, than vehicles like this could do the mining with minimally manned ships picking up the payloads and bringing them home.

Vacuum.  Extreme temperature swings.  And that dust.  In some ways, the dust is the worst part of the problem.

The lunar astronauts reentered their landers covered in it; pristine white space suits greyed almost black.  It got everywhere.

This is going to be an interesting subject to follow in the coming years.

Maybe I missed it, but I wonder if this robot has a rechargeable battery. If so, how does it recharge?

Excellent story, Ann.  Leave it to NASA to come up with a robot that digs effectively.  The barrel design is definitely very interesting as a way to overcome the lack of gravity.  Definitely a different type of design problem.

Agreed, Rob. Although there are also some constraints of Curiosity it doesn't have--those that would involve sensitive scientific instrumentation--and others it has that Curiosity doesn't, such as some mechanical design for soil scooping.

Wonderful, story, Ann. One thing this robot shares with the Mars Rover is the long list of constraints that the engineers need to manage in development. This type of project brings out the creativity in the design engineer.

A Frost & Sullivan study finds that increased cyber attacks are prompting a flurry of innovative protection tools.
Devices and interconnected systems are finding a foothold not only in our homes but in mainstream organizations. Here are three tips to mitigate the risk.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
