Starting a Robotics Program? Check this!

Here’s a video I did with Ruben Gameros, a grad student at State University. It’s about what it takes to start a Robotics program.

This was a hot topic in the STEAM Workshop last December in Colombo and Kandy, Sri Lanka. We know drones are changing the game in many areas. How about ‘Swarm’ robotics? Watch Ruben explain!

So many (scientific) ways to use a GoPro!

If you saw The Martian, you couldn’t miss the GoPro cameras strategically placed where Mark Watney (Matt Damon) hast to talk to other humans who were mostly absent.

It’s not exactly a webcam, but a powerful tool to ‘journal’ an activity a whether it is extreme sport, or something technical. I’ve started off using a GoPro in robotics, and it was quite revealing how the camera sees a manoeuvre.  I am now considering a class about the camera itself.

For this there will be two three cameras at work, in fact. The first, will be a webcam because of the expert I am going to bring in, via Skype. He will demo a GoPro and ‘teach’ us how to turn a GoPro into a scientific inquiry tool.WE will be using one in class as well.

The GoPro on Mars didn’t seem contrived – or a blatant product placement —  since some have actually been used in Space before. In real space, that is, and not on a movie set. And it has also gone to on some breathtaking missions — in a balloon, for instance.

Here’s one of my favorites. What a great way to demonstrate the surface tension of water, by making the camera a part of the experiment, while acting as a journaling device!

 

 

The GoPro is obviously switched on, and what’s really smart is how the editor of this video reverses the perspective. We finally see the scientists (the astronauts) through the scientific object (a submerged camera), and the water bubble acts as another distortion lens!

What would Annie Leonard say to Robotics students

If you’ve never watched “The Story of Stuff” now may be a good time. It’s about the ‘materials economy.’ I have used this as a great way to communicate, using simple language, and a great ‘story’ format. Including, great stick figures!

It deals with how (or why) stuff end up where they do – from toxic waste in a river, to social problems around villages where diamonds are mined. The former, as we have seen in this country, involves graphic images such as this picture below. The latter is a story in TIME magazine last week on Blood Diamonds.

This year the ‘Story of Stuff’ will be a must-see piece for all robotics teams around the world. Annie Leonard stumbled on this and researched this about a decade ago, and it is still relevant. If you have 21 minutes to spare, watch this!

If I could invite Ms. Leonard to speak to my robotics students, I wonder what she would tell them about following the ‘trek’ of ‘stuff that becomes trash.

For Robotics this year we’re re-imagining ‘Trash’

We just kicked off our new Robotics season in my school –my 5th year as coach!

With 26 students signing up, that’s more than twice the number of applications from last year. It’s a ‘good problem’ to have, to see kids become so excited about doing the hard stuff – the building, programming, doing the requisite research, and finally running those complicated missions.

On first glance, this year’s theme, Trash Trek,‘ is much less abstract than last year’s ‘World Class’ (around global education). Lots of big ideas to get our minds around the three R’s that could become a cliche unless we re-interpret RE-ducing, RE-using and RE-cycling . For instance, how about RE-imagining:

  • How far does the trash that gets into our bins has to travel? Could we calculate this (the ‘M’ in STEM) and display it somewhere? Perhaps in our communities — as some sort of a dashboard? If so, who would build the app? What would that display look like?
  • Who decides on the packaging that gets into the products we buy? How much cost will it save if we RE-fuse to ‘pay’ for this (with our landfills?)
  • Could our trash bins earn us money – a la Recyclebank?

I’m talking to all kinds of people – entrepreneurs, engineers,, designers etc who could come in and inspire my students. If you know someone, please call me, email me or send me a tweet at @heyangelo.

Some examples we might use for inspiration this week.

Technology in schools. Love it or hate it?

IMG_0302

Touch screens and Robotics. My classroom this yea

In my upcoming July technology column I analyze the pros and the cons of Technology in Education. A few in my network have asked me about my thoughts on this ever-changing topic. (In Oct 2014 I did cover it – “Disrupting Education)

Here’s a summary of what’s to come. As you and I witness the discomforting transition from text books to tablets, from hand-outs to videos-as-homework, from sequential ‘lectures’ to disruptive (noisy) small group activity, it’s easy to fold our hands across our chests and fight it. But there are some compelling arguments on both sides. The Wall Street Journal, and the International Association of Technology in Education almost in the same week ran Pro and Con arguments about Ed-Tech. I get both sides! In my classes I argue against the inane use of social media for the sake of ‘publicity’, but I encourage thought use of digital media with real, and real-time audience participation.

‘Hall and Stevens’ Vs Khan Academy. In my younger days, I had to thumb through Hall and Stevens, the geometry ‘bible.’ Today’s kids are learning geometry from a guy called Salman Khan, founder the free online learning portal for mathematics and science. (Fun sidebar: ‘Hall and Stevens’ is available as an eBook; flip the pages as if it was a real book, here: https://archive.org/details/schoolgeometry00hall

Screen Time vs Think Time. I am a big proponent of virtual and augmented reality, especially if it could bring in ‘distant’ experiences (Civil War, 3D models of engineering, space science etc), but I also aggressively advocate limited screen time. Odd isn’t it? That’s the dilemma we educators and parents face. Augmented Reality

Your son or daughter probably goes to school with a device in her backpack with more processing power than the rocket that took men to the moon, and this child wants to be… an astronaut? You’ve forgotten how to log into your son’s school website to download his missed homework, but… he’s found a way to ‘jailbreak’ your cell phone? There are ‘teaching moments’ in all of these.

Sal Khan speaks of the “fundamentally dehumanizing experience” in education. And he was not talking about teenagers and even pre-teens staring at their phones and not talking to one another. A real, ‘digital citizenship’ crisis, right now! He was referring to children packed in a classroom! Hmm!

Love it or hate it, technology is gate crashing our class rooms, just like ball-point pens or calculators once did. Are you ready for it?

My school profiled on US Dept. of Interior website

When Sec. Sally Jewell visited our school last week, little did we know how it would figure in the grander scheme of things. It was much more than a simple ‘air drop’ of a dignitary.

Turned out it was to kick off something bigger – a Listening Tour, of Native youth.

Yesterday we noticed that apart from the previous media coverage of this visit, the folks managing the communication for Secretary Jewell’s department had featured a lot of great shots of her engaging with our students. Two of the students featured are potential podcasters in my class on audio. Three are in robotics.

Here’s the video:

And below are some of my pictures taken at the event – also covered here on this blog.

This, taken in my class. Student Council president and robotics student explains how they approach a mission, program and document their work.

More pictures from my class blog, here

We often complain that government is tone deaf to much of what goes on in our communities.Speaking to Sec. Jewell, I could tell that this was much more than a token visit so as to report to the boss she’s been on the road.

We spoke of science. A lot! I mentioned that in the midst of so many changes in education, government seems to be not doing enough to promote science and technology.I mentioned that the State of the Union this year barely touched on STEM, despite Obama’s otherwise talking the talk on why we need more investment and more STEM teachers in science in schools. She was a good listener.
