Getting Started with Robots for kids and children in STEM this holiday season

Now's the perfect time to buy your kids/nieces/cousins some robots. Robots are a great way to get children excited about computers. Robots get them stoked in a way that a simple Hello World console app just can't.

If you're not careful you can spent hundreds on robots. However, I'm notoriously frugal and I believe that you can build some amazing stuff with children with a reasonable budget.

Here's some of the robot and electronics kits I recommend and have built with my kids.

4M Tin Can Robot

This is just a teaser but it's less than a trip to the movies. This silly little kit takes 2 AAA batteries and will take an aluminum can and animate it. It gets kids thinking about using found objects in their robots, as opposed to them thinking custom equipment is always required.


Quadru-Bot 14-in-1 Solar Robot

One of the challenges is "what age should I start?" and "how complex of a robot can my __ year old handle?" Kits like this are nice because they are starting with batteries and gears and include two levels of building, basic and experienced. It's also a nice kit because it includes solar power as an option and also can work in water (the bath).


OWI Robotic Arm Edge

This isn't a kit but it's a reasonably priced robotic arm to get kids thinking in terms of command and control and multiple dimensions. OWI also has a cool 3in1 robot RC kit if you prefer driving robots around and more "rebuildability."



This Christmas my 7 year old and I built a Mirobot. You can get pre-soldered and solder-yourself kits. We got the main Mirobot Kit PLUS the Addons Kit which includes clever additional modules for Line Following, Sound, and Collision Detection.

The whole Mirobot execution is brilliant. The hardware and software are all open source, so if you want to acquire the parts and make it yourself you can. You can get kits in various levels of preassembly.

It's built on an Arduino but is preloaded with some very clever software that takes advantage of its onboard Wifi. You can program it in C with Arduino tools, of course, but for kids, they can use JavaScript and an in-browser editor, much like Logo. It will create its own ad-hoc wifi network by default, or you can join it to your home network.


The creator is also building an Apps Platform so you can control the Mirobot from other apps within your browser and websocket your way over to the robot.

It took us about a weekend to build and you can see in the pic below that my 7 year old was able to install a pen and get the bot to draw a stickman. He was THRILLED.



This isn't the Intel Edison, although you can make some great robots with it as well. No, this is Edison, a little LEGO compatible robot from the makers of Microbric, a great robot platform from a few years ago. I actually made a Microbric robot in 2007 and blogged about it.

Edison is fantastic and just $50. If you're a teacher and can get a multiples pack, you can get them as cheap as $35 each. You program Edison with a clean drag and drop icon system then download the program to your robot with a cable from your computer's headphone jack.

Out of the box you can have it follow a flashlight/torch, follow lines on paper, fight each other in a sumo ring, avoid walls, and lots more. In this picture there's two Edison's stacked on each other. The top one has the wheels removed and replaced with Lego elements to make robot arms.


LEGO Mindstorms

OK, yes, LEGO Mindstorms are $350, so that's not exactly frugal. BUT, I've seen parents buy $500 iPads without a thought, why not consider a more tactile and engineering-focused gift for a girl or boy?

This is THE flagship. It's got Wifi, Bluetooth, color sensors, iPad apps, collision detection, motors galore and unlimited replayability. There's also a huge online community dedicated to taking Mindstorms to the next level. If you can swing it, it's worth the money and appropriate for anyone from 6 to 60.


Snap Circuits

I couldn't love Snap Circuits more. I started with the Jr. Snap Circuits and we eventually graduated to Snap Circuits Pro. They are my #1 go-to gift idea for kids of friends and relatives.

While this isn't a robotics kit, per se, it really builds the basic understanding of batteries, electronics, and motors that kids will need to move to the next level.


What robot kids do YOU recommend?

Parenting Tip: Star Wars Audiobooks, Family, and narrator Marc Thompson

July 21, '14 Comments [23] Posted in Parenting

The wife and the boys and I are often in the car for 30 minutes or more, heading off to various activities or events. We live pretty far outside of town, and when we need to head into the city, it's almost an hour. While we have lots of music, discussions, and what not, the boys aren't quite ready to listen to the unfiltered news.


BetrayalcoverMy buddy Dennis Petersen from LEGO recommended Star Wars audiobooks as a great way to pass the time as a family. I was a little suspicious, as I've listened to a lot of Audible audiobooks and it's been hit or miss. It all comes down to having a good narrator. Also, has the producer of the audio book decided that this would be a voice actor just reading the book or is this a radio production with music, voices, and sound effects.

The Star Wars Random House audiobooks with narrator Marc Thompson are AMAZING. My family and I have listened to nearly 50 hours of them and we still have a dozen and a half to go. These audiobooks strike a great balance between a dry reading (bad) and a the sounds of a movie (over the top). Marc Thompson does ALL the voices himself, and they are spot on. From Jabba to Boba Fett, C3PO to Darth Vader, we are consistently blown away by the quality of the voices. It's not distracting at all and it makes it much easier to follow the story.

You can buy any of the Star Wars audiobooks in Audible format at Amazon or as Audio CDs. You can also get them at iTunes. I recommend starting with the Star Wars: Legacy of the Force Series. The first book is #1 Betrayal. This starts 40 years the battle of Yavin when the first Death Star was destroyed. Leia and Han are married, they have two kids, and there's bunch of cool stuff going on.

Now at this point in the post, the non-Star Wars aficionados amongst you may have already checked out. But let me tell you this. My wife is NOT a Star Wars person. She couldn't care less. She slept through the movies. BUT, she loves these books. We'll get home from somewhere and she'll insist we sit in the driveway and finish a chapter. It's amazing.

The whole family has been having fun with these. It's much better (IMHO) than giving the kids an iPad or a DVD player on a long trip, and it's got us pausing the book and discussion galactic affairs with the 6 year old (who has turned out to be quite the the strategist).

Check out this YouTube video for a sense of the quality of narator Marc Thompson's amazing range. We've gotten to know him very well as a family, we think, while listening to these books.

Teaching Kids Electronics, Computers, and Programming Fundamentals with Snap Circuits

September 13, '13 Comments [33] Posted in Daddy | Parenting | Programming

I'm not particularly interested in my kids being programmers or computer people. I'd rather they be interested in life and totally geeked about something. If that's  computers, fine. If that's ballet, also fine.

That said, I think if they are going to be effective users (If not builders) I think they should have a basic sense of how electronics work.

I bought them a basic set of Snap Circuits, specifically Snap Circuits Jr. SC-100, which is just about US$20 on Amazon.

These are brilliant. Check this picture, as it's worth a thousand words and you'll get its genius immediately.

Snap Circuits SC-100

The 5 year old loves the motor and fan, as well as the speaker and noise makers. The boys have made doorbells, a light-controlled fan, lit-up LEDs and made an AM radio. Here's an Instagram Video of the 5 year old explaining his creation:

The pieces snap onto the grid with little buttons. The pieces are plastic and the wires run through them. They're not extremely resilient, in that they can break, particularly the capacitors, but it's actually nice to be able to see the resistors and other parts exposed through the plastic. It strikes a reasonable balance between being friendly to little hands, being sturdy, and actually working reliably as electronic components.


The 5 year old is no prodigy, to be clear, but he's already getting a general sense of electrical movement. He'll say that the resistors "slow down the electricity" and that the capacitors "store it up." He knows positive and negative, and how to use a multimeter to measure voltage. (I recommend a $10 multimeter as well for debugging your projects.) He's starting to look at doorbells and remote controls differently now, which means these little projects have already achieved my goal in just a few weeks. I anticipate they'll play with them for some months, forget about them, and then rediscover Snap Circuits every few years. These toys are great for a 5 or 6 year old, but even a 12 to 14 year old could totally appreciate them. I'm even running through some of the experiments and using the millimeter to remind myself of long-forgotten concepts.

We quickly outgrew the 30 parts in the Snap Circuits Jr. Even though it has 100 projects, I recommend you get the Snap Circuits SC-300 that has 60 parts and 300 projects, or do what we did and just get the Snap Circuits Extreme SC-750 that has 80+ parts and 750 projects. I like this one because it includes a computer interface (via your microphone jack, so any old computer will work!) as well as a Solar Panel.

The Snap Circuits SC-750 is a bargain at prices like US$75 if you can find it, especially considering how many tablets, Kindles and iPads some kids have.


The next Snap Circuits kids we're considering are either Snap Circuits "Light" that includes LEDs and Fiber Optics, although the 5 year old is pressuring me for the Snap Circuits Robot Rover. It'll likely be the Rover for the holidays around here.

I have no relationship with Snap Circuits, I bought these kits on my own and am reviewing them because they are awesome. If I could invest in Elenco Electronics, I would. The links here are Amazon affiliate links. If you use them, I can buy more Snap Circuits! ;)

Teach your kids to be fans

February 15, '13 Comments [15] Posted in Musings | Parenting

I love how social media shatters the barriers to entry for fans. I can tweet my favorite actors and authors, like my favorite comic artists or writers and connect with them in a way that has not just immediacy but a social connectedness that's so satisfying.

But there's also something to be said for a letter in the mail. Being a fan can be reading and enjoying but it can also be appreciating and reaching out. I'm trying to teach a sense of appreciation to my sons and encouraging them to reach out.

They love these books in the Joey Fly Private Eye series. They are super cute and great fun for the kids.

After reading them (many times) my boys decided that they needed to write a fan letter to the writer, Aaron Reynolds, and the artist, Neil Numberman.

It was more than a fan letter, though, it was a reminder there are Makers out there. There are real humans who think up and create the things they love. Perhaps it's also a reminder that they can be Makers as well if they choose.

Here's what they wrote (the 5 year old, so bear with him):

Are you making more Joey Flies? We think you should

The kids also mentioned that they liked tennis and that my oldest had recently lost a tooth.

And here's what showed up in the mail from Neil Numberman.

My sons as bugs, by Neil Numberman

Note the missing tooth on the bug on the right.

There are no words for the awesomeness of this. This is how you get life long fans, my friends.

Thank you, Neil. You should use your twitter more. ;)

Just please comb their hair and wipe their noses - My month as a single dad

October 11, '11 Comments [53] Posted in Musings | Parenting
Sponsored By

OnomatopoeiaThis month I've definitely realized that intellectualizing something is different from actually living it. I've been a single dad for the last 24 days. My wife has been in South Africa attending a family wedding and visiting friends while I've been alone with our two boys, ages three and five. It's been an experience, to the say the least. I decided to take half-time vacation and worked 10am - 2pm while the boys were in school.

Other than my obligatory 4 hours of deleting email work it was all home-making and kids for me. Who knew that single parenting is so hard? There were the first few days of "this is new," followed by "when is Mommy coming back," and the inevitable "so this is what life is like without Mommy." Definitely an emotional roller coaster for everyone.

Then there seemed to be a series of phases I went through, not unlike the phases of grief.
Shock - This phase includes disbelief and numbness. What am I gonna do? Gotta make sure the boys get to school each day. I have to sleep well, don't want to burn out too early.

  • Denial - After a few 3am surprise wake-up calls and obligatory potty emergencies, one tends to find themselves overwhelmed.
  • Bargaining - Just sleep through this one night and...
  • Guilt - Oh, I'm a horrible parent, the boys were late for school today.
  • Anger - This is so frustrating. Just do what I say and everything will go fine.
  • Depression - This totally sucks, how does anyone do this without help?
  • Acceptance - OK, I've got this. Maybe not the laundry, but lunches and playtime, I've got that down solid.

Death by a Thousand Tiny Cuts

Sometimes in a marriage (with kids) one tends to assume that their job to see the hardest. The thing is though, each role fulfilled by each spouse is different. The thing I learned about single parenting is that it's truly incessant. By that I mean specifically "it never ceases." Taken individually the tasks involved aren't difficult: make lunch, do laundry, buy food, but the problem is - it never stops. Just because I made meals and cleaned up all day yesterday doesn’t mean I don’t get to do it again today. And tomorrow. And the day after that...There's no credit to be brought forward for doing well yesterday: the clock resets, and it starts all over.

It seems that single parenting is the ultimate project management job. Every day included not the dozens of daily details that keep a house running but another dozen irregular details that were challenging to keep track of. I keep a lot of lists and notes and to-dos in my day job, but I had 4x the lists and notes and to-dos in this new single-parent job.

Playing to my strengths

One of the most significant things I learned about myself is to play to my strengths. While I may not be very good at remembering whose hair is combed or to wipe noses, I'm pretty good at teaching. I worked with the 5-year old who has been a little stalled at sounding words out. Turns out he's just bored with the material. Seems that "See Spot Run" isn't as interesting as "Batman." I found some age-appropriate comics (no guns, easier stories) and rather than trying to get him to read the dialog of the comics we focused entirely on the onomatopoeia action words. After doing this for a week I discovered that using comic books to teach onomatopoeia is a real thing that's done in schools. Cool!

The Good and the Bad

A good friend of my got divorced a few months ago. He made a large purchase and mentioned said to me,

"You know what the best part was? Not having to ask permission before making the purchase. And the worst part? The same."

That's a powerful and profound statement right there. It really stuck with me and totally applied in my month alone. On the one hand, it was really enabling and empowering to be able to change the system. We ate what we wanted (it was still good food, just what I wanted) and did what we wanted (zoo, museums, etc.) It wasn't that we didn't do these things when my wife is here but the point is, there's just one less adult voting. It felt like things went more smoothly, probably because any debates happened in my own head. It was nice to just decide things.

On the down side, there's no one around to brainstorm with. And there's no break at 3am. Or 4am. Or 5:30am. I don't know how single parents get a break, especially if they don't have family to lean on.

If it works, keep it. If it doesn't, change it

Now that the wife is back, we're going to look at some of the systems that I came up with and combine them with the existing ones that she had going. The goal is for neither of us to burn out doing our jobs. I think each person in a partnership tends to get hyper-focused on the task in front of them and forget the stresses on the other partner. Both of us have jobs that "never stop." We can't turn off and focus on something else just because it’s after 5pm. I really enjoyed my time with the boys as a single parent, and hope I never have to do it again any time soon!

The Customers (Kids) Don't Care

Another fascinating part to this was the complete ambivalence and amazing resilience of the children. While they were sad after Mommy was gone, a few days later "the new normal" become clear and they were back to business. I was a wreck, of course, but the kids didn't miss a beat. Their inherent wonderful "childish selfishness" remains intact, as it should. "What? Mom's gone? Ok, so are you the one making sandwiches now? Service! There's only one waiter in this lousy restaurant?"


I appreciated that my wife didn't just fly in, raise the landing gear and immediately take over the whole ecosystem. The boys and I had a good thing going and found a kind of equilibrium. A snotty nosed, wrinkled clothed, uncombed equilibrium, but equilibrium nonetheless. (Dad's skills lie elsewhere. Their pants were on straight 85% of the time, so I take full credit for that success!) My wife recognized that she was returning to a new house with new rules and we have spent the last few days talking about what worked, what didn't and what things we discovered while she was gone that we might want to keep.

Walk a Mile

It's certainly hard to be judgmental of any single parent when you've been one. We've all seen a single mom or dad walking around and wondered "where's the other partner?" Well, who knows, maybe in Africa, but you can bet that the one left is working hard.

I was explaining how college degrees work to the kids as we drove my a university this morning.

Me: "...Well, Mommy has a Master's Degree, she's very smart."

3: "Where is it?"

Me: "What?"

3: "The master."

Me: "It's on the wall in the office."

3: "Why don't you have one of those smartie things that mommy has?"

This made me remember that my wife has taken time off from one career to make the kids her career for a few years. I definitely understand my wife's job better after this month.

Behind every great man is a woman who is not impressed. - Me on twitter

Now I just need to figure out how to get her to do my job for a month so she'll appreciate how hard it is to tweet and restart Outlook! ;)
