ps4
Does the PS4 have this functionality? I see a lot of comments about the PS3, but not 4.

That reminds me of the EHT dance. Everyone knows the moves and the words but doesn't realize it. Then one day tinkering with a car, you get a shock from an EHT lead and the information comes magically to hand.
The dance involves jumping up and down while slowly spinning around and violently shaking the shocked hand while trying to put it under the opposite armpit without stopping shaking it.
The words (shouted in time with the jumps) are Bastard, Bastard, Bastard.
Everyone I've ever seen shocked by an EHT lead has reacted exactly the same way.
There must be some research that can be done in 5 minutes of zero g. The alternatives I can think of are 30 second bursts on the vomit comet, or full blown orbital flight. One may be too short, while the other may be too expensive. I expect this would hit the sweet spot for something, I just can't think what.
Just remembered drop towers, but they give really short times at zero g, comparatively cheap though.
We are / do / have.
New Horizons is heading for Pluto.
Dawn is off to Ceres having already surveyed Vesta.
Cassini is orbiting Saturn.
Curiosity is trundling around Mars.
And that's just the few that spring to mind.
There is a tendency to go to other planets and stay there rather than doing a tour of the solar system, but you can get a lot more science done it you have a few years in orbit, rather than an hour flying past. New Horizons is the exception to the rule but the physics of getting there make an orbiting probe a bit too tricky.
So, navigating by on-board sensors is proving tricky, but remote control is going ok.
Why not have the brains of the beast in a stationary location controlling the mower remotely using a stationary camera that can see the whole lawn. If you mod the camera for IR ( See http://www.hoagieshouse.com/IR/ ) and paint the mower black there'll be a really good contrast between the mower and the grass. Of course, the higher the camera the better, as you'll get a more plan view, do you have a roof overlooking the grass?
If you still want the whole thing in one unit, maybe you could use a downward looking wide angle IR camera mounted well above the mower body grass will be bright white to an IR camera so it should see the lawn edges. You'll still need a coarse position from a GPS or something similar though.
Thanks, I may have a try myself then.
Over here in England we have more problems with floods than fires, and the extra moisture should protect the roots from excess heat.
By the way, I found a patent for this has been filed.

Have two people carrying a box each linked by some wireless data transport mechanism. One person holds their box next to the victims pocket. The other person buys something at he supermarket and waves their box at the payment terminal. The two boxes relay signals from the card to the terminal and back. The terminal and card think they're in proximity and talk quite happily via the wireless link. Money goes from victim to legitimate retailer. Goods go anonymously to the bad guys to be sold on e-bay.
So, buy your RF screened wallet from Geoff's shielded wallet store now.
Put the vacuum pump tube near the top, then you don't need to go through the outer tube.
Get the temperature low before pumping out the air - the thermal conductivity of a vacuum is pretty low.
And as mentioned above, make sure your lid doesn't get frozen on. I've seen rigs like this blow their top due to frozen relief valves and it gets pretty violent.
The Rover chassis has proved to be an excellent design but maybe some new tools would be nice.
Something (laser maybe) to vaporize rock, and a Mass Spectrometer would be nice. The mass spec could also sample the atmosphere to see where the methane is coming from. Above all, now we know the platform can last as long as the solar panels stay free of dust, let's add a feather duster.
Surely if they can't move it, they can at least make some wheels sink deeper by spinning them. Maybe that would allow them to tilt the rover towards the sun and keep it alive.
Then you have a stationary lander rather than a rover but it's still good for some of it's science work.
Pluto (formerly the 9th Planet) was stripped of it's planet status in 2006 so surely any Planet X would be Planet IX now.
Unless NASA are hiding two planets.
However many, we should be told exactly where they are so the astrologers can be more accurate. How many of us aren't buying lottery tickets because our horoscopes are not telling us how lucky Nibiru will make us this weekend. Not to mention how many get run over because they didn't know how unlucky they were due to be.
