Polar Robots to Explore the Arctic
Roland Piquepaille writes "It's now almost certain that the world's ice shelves are melting. And while satellites provide lots of data about their evolution, ground-based weather stations could be even more useful. But if scientists can no longer stay on fragile and volatile ice sheets, what can they do? They can use specially designed robots called SnoMotes developed by U.S. researchers. 'The SnoMotes work as a team, autonomously collaborating among themselves to cover all the necessary ground to gather assigned scientific measurements.' More importantly, a SnoMote is an 'expendable rover that wouldn't break a research team's bank if it were lost during an experiment,' according to the lead researcher." Reader coondoggie adds a link to another story on these robots at Network World.
'cause like, polar robots have something better to explore than like the *poles* ?

I, for one, welcome our bi-polar robot overlords.
Tic-Tac-Toe, Global Thermonuclear War, and relationships all have the same winning move.
It sort of depends. If you're using the battery in the cold, it will discharge more quickly. If you're storing the battery, it will last longer in the cold. That's why those of us in a cold climate sometimes use a battery blanket (electric warmer) to keep the battery warm on those cold mornings. http://chemistry.about.com/od/howthingsworkfaqs/f/coldbattery.htm
A robot that goes out to collect data is just another scientific instrument to be used. Ultimately, people are still going to have to make sense of the data.
It takes a certain kind of person to want to go out into extreme conditions to take measurements. Being able to make meaningful conclusions based on them in the field when you have other things to worry about also takes a special kind of person.
Robots can go out, measure, and send back to you in your comfy office. The only sad thing is that we're moving towards a world of astronomers without astronauts, so to speak.
Without the adventure there is a lot less to inspire 8 year olds -- imagine if the draw to NASA had been "hey, kids! you can wear starched shirts and use a slide rule!" instead of "you can be a kick-ass fighter pilot, get a FREE Corvette and wear an Omega watch!"
The reality is that even the astronauts had to put on the starch and take out the slide rule, but that's not what you want to show kids up front.
That its being shown to them now that space is mostly going to just get the machine treatment and astronauts aren't going to do much past float around not be able to go to the bathroom for a few weeks, its small wonder that the smart kids who have the wanderlust as well look at Marine Bio as the new Apollo.
When I was substitute teaching about a year ago lots of kids wanted to be marine biologists. none of them were saying astronaut anymore.
If you want news from today, you have to come back tomorrow.
Batteries at lower temperatures tend to have longer lives, don't they?
Chemistry 101, lower temperatures mean lower reaction rates. Lower reaction rates mean less voltage, power etc.

It's now almost certain that the world's ice shelves are melting
... only for some value of "certain" which equates to "certainly not" is that a defensible statement, methinks.
Funny, that's not what the actual facts show. We're at the highest ever recorded ice cover in the Southern Hemisphere right now:

which already more than balances out the Northern Hemisphere's recent decline,

and now that the PDO has entered a cool phase,

it's as certain as anything to do with climate is that you're going to see that trend smartly reverse itself as well.
Soooooo
...Cartesian robots are angry about being passed over for these jobs without even being considered.
The laws of probability forbid it!
