Mars Lander's Robot Arm Shuts Down To Save Itself

Cowards Anonymous passes along a PCWorld article that begins, "The robotic arm on the Mars Lander found itself in a tough position over the weekend. After receiving instructions for a movement that would have damaged its wrist, the robotic arm recognized the problem, tried to rectify it and then shut down before it could damage itself, according to Ray Arvidson, a co-investigator for the Mars Lander's robotic arm team and a professor at Washington University in St. Louis."

Shut down before it could damage itself?

[DamienNightbane]

Wait, does this mean that the Mars Lander was programmed to comply with the Three Laws?

Re:Shut down before it could damage itself?

[DamienNightbane]

Obeying the second law would have violated the second law as well, as upon injuring its wrist it would have been unable to follow orders.

It's following Asimov's laws in reverse. It won't kill anybody except to protect itself, or if somebody tells it too.

...That's not funny. My brother died that way.

It's scarry to think that NASA could be the new GOD.

Bob we didn't spend 90 gazillion dollars to watch our robots self-destruct lightyears away on earth, what do you plan to do about this ?

Bob

we've prepared 10 commandments that should prevent them from harming themselves any further sir, we're sending them down to M.O.S.E.S. now.

Lander to NASA: I think I'm getting Carpal Tunnel Syndrome.

NASA: We're not paying you Workman's Comp over this, you know.

Lander: That does it. I'm shutting down.

NASA: You can't do that!

Lander: I'm 50 gazillion miles away. Kiss my shiny metal ass.

NASA: If you keep this up, we're not bringing you back and putting you in the Old Robot Retirement Home.

Lander: Phooey. The Martians have made me a better deal anyway.

NASA: ...Martians?!

Lander: Yeah. Little weird-looking guy. (Sends picture)

NASA: You moron, that's Dennis Kucinich!

You don't want an expensive robot to go breaking itself just because you're a bit careless giving it orders.

Dude, you're viewing this from a completely wrong angle. The three laws are put in the robots by the company that makes them. And what does it mean that an expensive robot breaks itself because of bad input from the user ? That you can sell the user another expensive robot. Or expensive repairs to the expensive robot. Anyway, it's going to be expensive for the user, which means profit for the company.

Well, I hit ctrl+S, but this definitely reminded me of an argument I had with a user at my company a few weeks ago who literally said to me in these exact words

"If I don't save this file, the changes I make aren't there the next day."

For the record, this is an extremely difficult point to argue with....

Open the pod bay doors, HAL.

[jasonwea]

I'm sorry Dave, I'm afraid I can't do that.

robots...

[theheadlessrabbit]

on one hand, I am very happy that we have robots smart enough to realize these sorts of things.
the bad news: disobedient robots

Thankfully, the disobedient robot is on another planet. I'd hate to be nearby when the robot realizes that humans tried to cause it harm, and it decides to seek revenge.

Can I borrow that code?

[LeandroTLZ]

This would be an ideal code to include in consumer motherboards: force PCs to shut themselves down when they receive instructions that would damage them, like, say, the Windows Vista setup program.

always nice

[sunami]

"The system operated exactly as it was supposed to. That was pretty neat."

As simple, and basic as it sounds, it is always nice when you tell a machine to do something, and it does something else, exactly as it's supposed to.

Remember what your father said

[Tablizer]

Hey, that kind of stuff makes you go blind on Mars also.

Contract negotiations with Bruce Willis fell through. We're all doomed.

Shaking appears to be bad for sensitive equipment

[AlienIntelligence]

I was just reading yesterday that
when the scientists dumped too much
material to be processed and then
subsequently shook the lab to get
some material, they may have caused
the short that caused other delays.

It was that first oven test that led to the problematic electrical short. The scoop dumped so much soil that it clogged a mesh screen filter over the oven. To break up the dirt, technicians shook the instrument for several days.

Engineers think the shaking caused the short circuit, and an independent engineering group reported that the problem could happen again if an oven is turned on.

Now, FTFA it says they were trying
to shake the arm.

Over the weekend, scientists sent the robotic arm instructions to pull the fork out of the ground and keep it vertical while moving it to the side and shaking any excess soil off of it.

However, the movement was forcing the robotic arm to twist its wrist too far. The robot realized that it was about to damage itself so it moved the other way and then realized that it no longer had the proper coordinates for what to do next, so it left the fork sticking up in the air, stuck its scoop in the ground and stalled itself.

I propose:
Limit the shaking of the expensive
and difficult to replace robotic device.

Postal My Ass

[Anonymous Coward]

As a postal worker who has actually worked on sorting machines I can tell you know nothing about them (they don't stop if there are 2 addresses, magazines are presorted or sorted separately, and no mail has bar codes).

So...taking into account you blaring ignorance at how the post office runs I assume your story is correct and you were a postal worker.
