What the Mars Rover Opportunity taught us

15 years, covering 28 miles on Mars, the Mars Rover Opportunity came to the end of its mission this week. Basically it lost contact with Earth last June; NASA had to finally call it Mission Accomplished. The gutsy little Rover was part of a tag team (Opportunity landed on Jan. 24, 2004, Spirit had arrived a few weeks earlier.)

Gutsy doesn’t even start to describe the robot that refused to quit. Here’s how Jet propulsion Lab described it in a few bullet points.

  • Set a one-day Mars driving record March 20, 2005, when it traveled 721 feet (220 meters).
  • Returned more than 217,000 images, including 15 360-degree color panoramas.
  • Exposed the surfaces of 52 rocks to reveal fresh mineral surfaces for analysis and cleared 72 additional targets with a brush to prepare them for inspection with spectrometers and a microscopic imager.
  • Found hematite, a mineral that forms in water, at its landing site.
  • Discovered strong indications at Endeavour Crater of the action of ancient water similar to the drinkable water of a pond or lake on Earth.

Opportunity and it’s cohorts explored the theory that Mars could be (or support) a “habitable environment” Its longevity, and ability to literally dust off its problems showed future explorers that this is possible. It’s very landing inspired future landing innovations to distant planets, while its photographing of blueberry-like rocks gave researchers back on Earth an idea of what hematite means to us.

This spunky robot also has a delightful design. For a few years I would borrow a wheel of (a replica of) its sister bot, Spirit, from the Mars lab at ASU, and display it in my class. It definitely inspired me to take robotics more seriously.

Automation’s great – When you’re the manager, not the person turning the widget

This article, with a Phoenix, Arizona dateline sums up much of the issue we have with technology, robotics and automation.

As I teach students about the pioneers of tech, from Edison to Jobs, from Babbage to Berners-Lee, I have to temper it with discussion on what computers in general (and algorithms / automation in particular) are doing for us. Or will do for them when they enter the workforce.

The article states that Some economists have concluded that “the use of robots explains the decline in the share of national income going into workers’ paychecks over the last three decades.”

In a state where autonomous cars are quite common –at least the Waymo variety being test-driven in the Chandler & Mesa area, algorithms and jobs are on top of our minds!

You never know where your students end up

If only we could turn back the clock to thank a teacher who put us in place, or taught us a theorem that changed our life. Here’s one of those moments.

Fascinating titles as students publish eBooks

As a final project to wrap up their mastery of layout and editing tools in Microsoft, my students created a 22-page book. Each book was published as an eBook.

To kick it off, they brainstormed themes for their book. Followed by a unit on creative book titles, I was fascinated to see them come up with titles such as these:

  • Is Amelia Earhart Dead?
  • Oh, the Creatures You’ll Find!  – Mythical creatures
  • A Helping Paw   – On dogs that risked their lives for humans
  • The Ultimate European Bucket List – no explanation needed
  • A Pigeon’s Eye View of Europe
  • Johnny B. Goode Tonight   – Classic rock songs
  • Tragic Waters   – The most disastrous storms
  • Geek out with Dragons – For readers with a serious Harry Potter obsession

More than a 100 books are being uploaded today and tomorrow! Here are two. Click on images to launch the books!

Robots that could run farms? Should bots do that?

Have you seen this concept video? Robots that perform farming. It’s disturbing to say the least, to think that the field of robotics is being applied to areas we never used to anticipate. No longer ‘programmed’ robots, these are machines that learn and apply what we now call machine learning, to the environment they are placed in. For instance could a robot learn about —and work in consort with — other devices on the so-called farm. (It’s actually a greenhouse.).

To put it in context, if robots could shuttle between products on a shelves in an Amazon warehouse, this is just an extension of that – an industrial application. We are at the starting blocks of the Fourth Industrial Revolution, so these upheavals – technological, economic, environmental, social etc— are just beginning to show up. I’ve been critical of the rush to apply AI into everything, holding out some optimism that these players and industries might still need some humans, while replacing others.

It has been featured in Wired, and CNBC.

Also there’s another video worth watching.

Do photographs really enhance our memories?

Have you ever questioned whether taking a photograph is the only way to preserve a memory? I used to be the person who always carried a camera. Sometimes two, plus a tripod.

But over the past few years I’ve begun to wonder if preserving important moments in life on a camera –and processing these salient moments through a camera lens –is actually useful. The question resurfaced in the past few days, twice.

First Google keeps sending me albums it randomly puts together, without me as much as even asking for this feature. (Yes, Facebook users, I see a lot of that too, ad nauseam.). I find that irritating. Who does it think it is to decide what I want to remember?

Second, a student commenting on a discussion in class, mentioned that one thing that irritated was having a parent point a camera at everything. The student complained that it was terrible how adults appear to want to save every moment, but miss looking at Real Life, as is.

The discussion turned to smart phones, and how everyone today pretends to be (or yearns to be) a photojournalist, documenting history as it were. The pictures are often badly taken, have no photographic or artistic value. And yet the screens are held up. The shutters click. Those with absolutely no photographic skills, can of course use built in filters, either on the device or on platforms such as Instagram.

So my question to them was this: If you were to witness an unfortunate event, or a run into a celeb you least expected, would you process it through your God-given optical lenses, and store it in your internal memory? Or would you rather take it in through a camera lens, and store it in the Cloud – just in case?

And my question to you: Is there a  significant event seared in your memory that has absolutely no photograph to document it? If so, what was it? More important, if you had a chance to go back in time, would you  (or have someone) photograph it?

 

Could MIT reinvent itself with an ‘ethical’ approach to AI?

Just in time, as the field of AI ramps up. (Also by some coincidence, a week after the cover story in LMD.)

MIT has just announced it will add a new college, the Stephen A. Schwarzman College of Computing, dedicated to world-changing breakthroughs in AI, and their ethical application. The college will “reorient MIT” to add 50 new faculty positions, and give  students in every discipline an opportunity to develop and apply AI and computing technologies.

The term ‘ethical’ keeps popping up these days in relation to Artificial Intelligence. MIT expands on this, saying it will “examine the anticipated outcomes of advances in AI and machine learning, and to shape policies around the ethics of AI.” As I have mentioned elsewhere, most experts (from Elon Musk, to Bill Gates to Berners-Lee aside) agree that we are just at the tadpole stage of the life-cycle of AI.

However, some, such as sci-fi writer, Isaac Asimov and even Stephen Hawking have had concerns. Hawking, for instance remarked that “we all have a role to play in ensuring that we and the next generation have the determination to engage with science … and create a better world for the whole human race.” MIT seems to be the first large institution to take up this mantle, and in the process, redefine and re-invent its role in education.
