Opportunity: Hail the Amazing Rover!

NASA's Opportunity rover is now 8 1/2 years (3043 days) into its 92 day mission and still going strong!  It powered up after its fifth Martian winter and is on the move.  It is a little pokey given the amount of dust that is collecting on the solar panels.  Still, we at the House Full of Nerds are impressed at this engineering accomplishment.  This little guy landed on Mars on January 25, 2004.

The twin rover, Spirit, became mired in deep sand and its last communication with Earth was on March 22, 2010.  Opportunity is currently alone on the red planet, but will be joined by the next generation in rover technology in August, 2012.  Curiosity is a substantial mobile laboratory with a nuclear power source.  The landing system is unique and we are hoping for a good start for the mission.

The vista circa May, 2012.  This is the largest crater in the journey and represents the oldest rock strata.  You can see the edge of one of the solar panels in the foreground.  The dust accumulation is reducing power output.

Just to give you an idea what Opportunity has been up against, Mars receives roughly 43% of the amount of sunlight that Earth receives.  With a thin atmosphere, it can't hold heat well.  The high summer temperature ranges up to 23 degree F.   Mars has frequent, large scale dust storms which sometimes cover the entire planet.

Discovery from late 2011:  Gypsum like deposits caused by free water percolating through rock strata.  Opportunity and Spirit both observed evidence of past free water on the surface of Mars.

Congratulations to Opportunity and the many builders and mission operators of NASA.  The mission is now open ended.  We hope Opportunity keeps producing good science for many days to come.

Geek Pride Day!

Today is Geek Pride Day!  It is also the 35th anniversary of Star Wars Episode IV.  In some quarters it is Towel Day in celebration of the Hitchhiker's Guide.  To celebrate, I have posted some photos of some of my favorite geeky things.

 

FIRST: A Day at the Kansas City Robotics Competition

Claire (aka: gingercat) loves showing off her swag.  This is the collection from an hour and a half in the pit area.  Teams swap and give goodies away.

One of the best things about FIRST is that competitions and the pit areas are free and open to the public.  As long as you are wearing safety glasses, you can wander around and talk to the teams about their robot designs.  The kids love to show off their bots.

A slice of life in the pits.

Tech inspection.  Robots are checked for weight and regulation equipment.

Before I go any further, I have to recommend my Spousal Unit's blog on the subject at

She is not a techie and will approach this from a different perspective.

Moving on...

The work doesn't stop with building robots.  Each assembly and sub assembly must be documented with CAD software.   The team has to build a website and create promotional materials.  Some of the teams go all out doing community outreach programs as well as promoting STEM to girls.  The latter is important given the number of engineers and designers we need to have this be a country of makers.

OK, that's enough of the semi-political advocacy for my girls.  Now we are ready to rumble!

You might want to watch the overview video at FIRST Rebound Rumble Animation on Youtube

A FIRST round always starts with an autonomous task with plenty of points to be grabbed.  The robots are programmed and loaded with sensors.  This year, they had to navigate into position and shoots baskets without hairless ape intervention (except for the little used Kinnect option).

The real action starts during the driver phase.  Each robot typically has two drivers and someone watching the clock and the field.  Microsoft donated Kinect systems to FIRST this year.  One of the regional teams opted to use one for hybrid control of the robot during the autonomous phase.

The parts kit includes the same batteries, PLC and I/O system.  Some of the motors are standardized as well.  There is a weight limit and a parts cost limit of $3,500.

This was a unique design and was foolproof as long as no opposing robot ran bumping interference.  That is legal in certain zones in the field.

Here is the amazing thing:  Each team started with the same box of parts, rules and specifications to create a practice field.  From there, design diverges as each team prototypes and builds their robots in six weeks.  They then crate the bot and ship it.

Of course they don't do this alone.  There are teachers, sponsors and mentors.  We talked to one team mentor who mentioned that their school is just outside the gates to the Fermilab.  Yeah, that Fermilab; the one with the particle accelerator.

There were a few catapults and many driven wheel shooters.  Some had turrets that could be rotated as needed.  We saw many different ball grabbing designs.

On top of all the other engineering challenges, the balls were made of Nerf like material that degraded throughout the competition.  Hardness, texture and friction changed as they went along.

Can you believe that every one of these machines was designed and built by high schools students in six weeks?  Bear in mind that almost all of these kids are in AP heavy programs.  It's fair to say that the bell curve is skewed two or three standard deviations in the arena.

Engineering is serious work, but so is Gracious Professionalism.  Teams cooperate.  They share parts in the pits.  The kids spent six very long weeks building their bots and then live in the pits for almost three days.   They are competing for the same scholarship dollars.  For the most part, they are loving every minute of it.

More about Gracious Professionalism and its partner, Coopertition are found on the FIRST website at  http://www.usfirst.org/aboutus/gracious-professionalism


While the goal is to bring up the next generation of engineers, the teams are still in it to win.  This year there were two teams that absolutely dominated the field.  Here they are in a four minute pit stop between the semi-final and the final round.  That's just enough time to swap batteries and check all of the electrical connections.

Terror had two names this year.  Introducing the Bomb Squad and Team Titanium...

So now it is time to prep and shoot.

And shoot some more. 

To say that the Bomb Squad was a shooting machine would be somewhat redundant, but seeing an elegant design in action is inspiring.  Team Titanium was no slouch, either.  But I think that the Bomb Squad sucked up more balls and made more shots.

This was not the final round score, but you get the idea how this Red Alliance did overall.

We walk into Hale Arena each year to watch the regional competition and cheer on the local teams.  I remember the first time as I looked around and said "I smell nerd."  It's like being at home except a lot louder and with more and better technology.

Claire wants to go to the local high school that has an engineering program and a mature FIRST team that has been to the world championships twice.  If she chooses to follow through and makes the team, we'll miss her during the long, sleepless build weeks.  But we'll know she is in good company.

Last Stand at the Remington: Starring Godzilla and a Noiseless 8. Really.

WARNING:  This blog post contains disturbing images of potential historic typewriter abuse.  The viewer is advised that no typewriters were harmed in the making of this flight of fancy.

My Noiseless 8 still requires finesse.  I find there is a fine line between over-powering the key stroke and getting a proper space advance.  It is loosening up with use and I am experimenting with Remington gun lube.  As for me, in the age before word processors, I could actually spell words like "heroes".  Sad.

So, just when you thought this blog could not get any weirder, along comes a story featuring Godzilla, a robot and a very strange vinyl toy I can pretty much guarantee you have never seen.  Before I go any further, I must give credit where credit is due:  it was a Typospherian and blog follower, teeritz, who suggested that the Remington Noiseless 8 looked like a Deco skyscraper.  I just took that concept a step further.

OK, I took it a few steps further.

The story starts with a trail of destruction that did not get captured on a digital sensor.  Well, it was, but the photographer was crushed by falling debris.  The best documentation from the scene starts with a lone robot, Commander Zogg, making a valiant last stand at the Remington Building.

The National Guard tried; they really did.  If you are at all familiar with the depredations of Godzilla in Tokyo, you have an idea of how well that worked out.  Still, the government had one secret weapon in reserve.

Pretty much any pilot worth their salt can tell you that we're all just one atomic breath weapon away from eternity.  Just like those poor Japanese pilots.  It was a nice plane.  Bummer.

Things were looking pretty grim for our hopeful hero.  A space robot can only take so much.  The radiation was getting intense and Godzilla was throwing everything he could get his scaly claws on.

Commander Zogg withstood a barrage that would have brought the great kaiju of Japan to their knees.  The roar, while painful to his auditory sensors, was manageable.  He easily absorbed blast after blast of the atomic breath by rotating the frequency of his quantum resonance shielding.

People fleeing in terror stopped long enough to look over their shoulders at the tremendous confrontation.  At least one adorable boy in a private school uniform even dared to voice hope: 

"It's Commander Zogg!  He will save us!"

But hope is a rare and tenuous commodity.  How quickly a situation can change.  And change it did when Godzilla unleashed his most powerful weapon:  the full body nuclear pulse.  Suddenly, it appeared that Zogg, the bravest robot of his time, was doomed.

As Commander Zogg's strength began to wane, he was surprised when the mighty lizard paused his orgy of destruction.  As if in a dream, a new hero appeared.  Yes, it was the mighty Astro Mu Earth! He came from Japan by way of Jupiter as soon as he detected the world wide distress signal.

Godzilla isn't known for restraint or logic.  While quasi-intelligent, he is primarily a creature of passion and instinct.  Few weapons are known to injure a monster of his stature.  However, he does remember pain.  He also remembers the Oxygen Destroyer all too well.  Having been skeletonized  once before, he eyed Astro Mu's canon with trepidation.

  
With a grudging snarl of admiration, the Tyrant Lizard broke off his assault and trudged through the debris of New York back to the inky depths from whence he came.

New York, or what was left of it, was safe once again.  Godzilla may return, but he will certainly face new, determined defenders.

        The End

Behind the Scenes

With the largest budget ever in the history of Vintagetechobsessions Productions, the crew created an unparallelled  alternative reality for our viewer's pleasure.

Typewriter safety is a priority at the studio.  In order to assure humane treatment, a representative from the Typewriter Protection Society (TPS) was on hand to witness filming.  An after action report was filed in accordance with the Typewriter Safety Act of 2004.

Cast and Crew:

Godzilla                         Shogun Warriors Godzilla (second version*)
Commander Zogg         Himself 
Astro Mu Earth             Reproduction Astro Mu (because the real one is unattainable)
Remington Building     The Eight Millionth Remington Typewriter

* Yes, it takes a true Nerd to know the difference.

The Outtakes

Ultraman was originally cast as one of the heroes.  A product of the studio system, he looked heroically heroic.  However, his conventional good looks did not set well with the the Executive Producer's vision.
