Personal Robotics

Monday, January 25th, 2010

Wow. First, computers were these gigantic machines that took up all the space in a single room (or more!), made for the government and big corporations. Then prices dropped, technology improved (Moore’s law), and the computer was personalized, and today everybody practically carries one in their pocket.

When I had to first decide what to major in when in college, I did want to major in something to do with robotics. Robotics however, wasn’t exactly a popular or major discipline that was easily available anywhere. Fast forward to today .. we have personalized robots.

Enter the world of Arduino.

Here’s a very basic robot that exhibits basic facial expression, speaks from text, complete with LEDs. This is hilarious. And SOOOOO COOL.

Read more about the Ganzbot here.

Next, we have Arduway, a Segway-like self-balancing robot. It’s like creating a fragile and little life-form from your bare hands.

Read more about the Arduway here.

And alright .. enough of toys. How about a real world application? Here’s a robot that uses GPS and other sensors to steer a 30,000 lbs beast of a machine for a farmer – to harvest soybeans!

Can’t wait for the robotic revolution!

If you are interested in getting started with learning Arduino, here’s a quick link to the books recommended by the official Arduino site.

Roll with uncertainty

Saturday, November 14th, 2009

A lot of time we spin our wheels going back and forth when faced with uncertainty in life. I know sometimes I tend to overanalyze and try to risk-assess something to death, and still get no closer to a decision. At the last Y Combinator Startup School in Berkeley, Mark Zuckerberg said (paraphrase),

“In a world where everything around you is constantly changing quickly, the most dangerous thing you can do is to not change”.

And that’s especially true in the technology business. As a technologist, if you don’t learn to love it, you won’t keep up. I’m a big fan of Tina Seelig and her famous talk at Stanford titled “What I Wish I Knew When I Was 20” (I can’t highly recommend it enough, please check it out and you can thank me later). That talk has received so much interest that it’s now a book.

Going back to uncertainty, it just never stops. If everyone had equal visibility and the exact equal amount of information for decision making, then everybody would be able to make the same sound decision. Now making decision, with incomplete information .. that’s how you win; how you get an edge on the competition. Also not easy, but you have to roll with it.

In a recent Q&A with Tina on BNET,

Q: Your latest book is entitled What I Wish I Knew When I Was 20: A Crash Course on Making Your Place in the World. So the inevitable question: if you could go back and give your 20-year-old self just one piece of advice, what would it be?

A: I would tell myself that the uncertainty of life never goes away. There are always choices in front of you, challenges to overcome, and failures from which you need to recover. If you embrace the challenges and view them through the lens of possibilities, then you will not only be happier, but will be much more likely to turn the inevitable obstacles into opportunities. The world is always changing, and it is up to you to be flexible and optimistic. With a positive attitude and creative thinking, most problems can be viewed as opportunities in disguise.

Yours truly is reading this book on my Kindle. I. highly. recommend. it.

Shai’s Divide and Conquer!

Monday, April 13th, 2009

Shai Agassi is a real genius—one of my rock stars that I’m just dying to meet. I’ve already got to meet the other big name in electric cars, Elon Musk from Tesla.

He has said before that he’s good at break big problems into smaller problems, solving the pieces, then aggregating the results. I’m not familiar with his work at SAP, but clearly he’s proved this with his divide-and-conquer approach to problem solving here. Computer scientists make some of the best problem solvers out there.

In this TED talk, Shai talks about a shift in thinking: viewing the electric car’s battery a discrete unit that’s interchangeable, vs. today’s mentality where the car is one with the fuel tank (who would buy a car without a fuel tank, or vice versa?)

I’ve previously blogged about unbundling production from delivery before with examples of Amazon.com and it’s IT infrastructure, mobile phones as a poverty buster, and this is kind of like that, but with other concepts tied in – e.g. subsidized pricing (e.g. like how cell phones are subsidized by carriers).

The analogy Elon Musk uses (I can’t find where he said this, but I swear I remember him saying this), is like air travel today. I can fly to Europe from California for $500. But that’s because I’m not the first person to ever fly on that plane, nor will I be the last; the same air plane gets reused over and over for many flights. The point here is that the owner of the plane doesn’t have to recoup the cost of the plane with a single flight, it is done over a period of time. The higher the utilization rate, the faster they recoup the investment.

That’s why Elon’s SpaceX goal of building a reusable rocket is so revolutionary (most people don’t realize this) and is an important step for man-kind. Imagine being able to fly to the moon or other planets in our solar system for the price of a flight ticket?

Back to Better Place. In Shai’s talk, he shows how battery for electric cars follow a Moore’s law-like curve; battery prices will drop as its technology increases. By unbundling the ownership of the car and the battery, you can increase the utilization rate per battery which result in people owning these cars having access to the latest and most efficient battery at that time (vs. someone stuck with the same battery for the lifespan of the car). Small but important point.

Shai’s a very cool guy who is literally, changing the world. I’m a big fan.

Mobile data adoption on the rise

Saturday, July 26th, 2008

Some mobile data trends (numbers + commentary):

  • Total mobile data revenues for 2007: US$157 Bil
  • Total mobile data revenues for Q1 2008: >US$49 Bil, 42.7% y-o-y increase. Of this, non-SMS data made up approx US$17.46 Bil (35.6% of total data revenues)
  • Mobile data revenues is now almost 20% of mobile operator total revenues
  • 40% of world’s data revenues come from APAC (>US$20 Bil in Q1 2008)
  • Fastest growing is EMEA, which despite only representing 2% of world’s data revenues, is growing at 91.7% y-o-y to US$927 Mil. This acceleration is aided by the 321% y-o-y increase of HSPA subscribers
  • Operator that generated highest non-voice revenues this quarter is Japan’s NTT DoCoMo (US$3.6 Bil), overtaking China Mobile (US$3.5 Bil)
  • As a % of overall revenue, Filipino mobile operator Smart Communication is the world’s market leader, and the only carrier to depend on non-voice revenues for > 50% of its income *I wonder how much of this is attributed to microfinance and mobile payments i n that region, hmm ..

And as always, I’d like to extrapolate some meaning from raw numbers, so let’s go.

Obviously, the trend clearly indicates that your cell phone is becoming more of a general purpose computing device (like your desktop PC, as opposed to a single-purpose device that makes phone calls only), with more rich features that PCs don’t have (e.g. GPS and accelerometer), and it’s all hooked up to the wonderful internet.

Action items: First, we have to get out of the habit of thinking of cell phones as desktops, because the use-cases are completely different; treating them as such is the clearest way to die. Second, with mobile devices becoming more powerful (computationally, Moore’s law), having more storage (cost of storage trending down, Moore’s law), internet connectivity improving (coverage, speed, cost, again, Moore’s law), and throw on top of that added new hardware features (GPS, accelerometer, etc) .. this sounds to me like having richer and more powerful tools in a technologist’s problem solving warchest — so bring on the problems, bring on the opportunity.

I chuckle as I write this because this reminds me of what Stanford University’s president John Hennessy once mentioned in an interview, about his prediction of what would happen in mobile technology down the road:

  1. Information at any where, at any time, on any device
  2. A user experience that works well, independent of what that information is: Be it a Google map, stock listing, web site, email, etc. Making that convenient and natural, and seamless
  3. Imagine walking in a brick and mortar store and wanting to buy a product. I want to look up my phone and do a price comparison on the product and know what people are saying about it. I want to do that in 5 seconds. Today, I have to open a browser, visit a review site, search, etc. (too much work)

The iPhone is clearly one of the pioneers in making that happen, especially with the iPhone app store. I have previously commented on why I think the iPhone app store is very much Apple’s competitive advantage, and as much as I root for Google’s Android, it remains to be seen how the Android incarnations would address the iPhone platform threat.

With mobile carriers having trouble increasing revenues from voice, you betcha they are thinking of every single way to make money from mobile data. I have also previously written a rant about iPhone/AT&T’s data pricing strategy (there’s nothing wrong with the strategy per se, I’m just a price-sensitive geek at heart).

Now’s a good time to be a mobile app developer .. there’s money already being pledged for the BlackBerry platform (US$150 Mil) , Google Android platform (US$10 Mil), and the iPhone platform (US$100 Mil). I can see mobile carriers snapping up these mobile app startups to further bolster their mobile data revenues. Technology IPOs are almost non-existent today, much to a Silicon Valley VC’s annoyance, so exits via acquisition to a mobile operator would make sense for mobile app startups.

I’m passionate about innovation and problem solving with tech, and I can’t wait to see more new applications in mobile given these trends. The question I try to ask myself given these stats above are, “what else is possible today that wasn’t yesterday?” Think it about it.

If I were to wish for anything, I should not wish for wealth and power, but for the passionate sense of the potential, for the eye which, ever young and ardent, sees the possible. Pleasure disappoints, possibility never. And what wine is so sparkling, what so fragrant, what so intoxicating, as possibility!
–Søren Kierkegaard

To go off on a slight tangent, it’s interesting to note that a Filipino mobile operator is the world’s market leader in depending on non-voice revenues. I wonder how much mobile payments contribute to their revenue stream, and how much of that is related to microfinance. If anything, I think that could be a classic BoP example because it would illustrate another example to bust the myth that corporations cannot make a significant and sustainable profit in selling to the poor.

If I was all the other mobile carriers looking to make more $ from mobile data, I’d be watching this Filipino carrier, Smart Communications closely to glean some lessons.

And I’ll end this blog post with vivid taste of possibilities for mobile — a very cool Android project in the making called Enkin. Do check it out!

Towards a greener computer–but what does that really do?

Friday, March 7th, 2008

MSI announced that the company has recently invented the world’s first powerless air cooler for computer motherboards. For those new to computer hardware, as we ignore Moore’s Law and advance computer technologies by making them faster and store more data, cramming more and more transistors into a piece of silicon, the heat generated by all these components start becoming a non-negligible problem–as anyone managing a data center with hundreds of computers will identify with.

There are many ways to cool the insides of a computer, but the most common is through the use of heatsinks and fan’s. Computer hardware junkies prefer a more advanced hack: liquid cooling, a more quiet and efficient (and l33t) way of dissipating heat from their overclocked CPU’s. This invention by MSI makes the fan inside your computer power-free, thus less power drawn from the computer power supply.

The basic idea employed here is one derived from the Stirling Engine. MSI’s invention captures the heat from the component, whose energy is then converted to push the fan blades around, which in turn cools the heatsink.

From their press release:

The “Air Power Cooler” transfers the chipset heat into air momentum, when the air becomes hot, the air will expand then push the fan to rotate and In doing so cooling the heatsink immediately. After the air moves from the bottom to top of the piston, the air will become heavy to push the up piston down. The better air piston design can transfer over 70% heat power and transfer to air power, that’s great efficiency transfer from Stirling engine theory. In a comparison with solar power the transfer rate is only around 20~30% requiring more surface and as a result cost.

I think the claim of besting solar power is interesting, but would like to see some independent tester verify that statement (just for my assurance that this isn’t the typical corporate PR mudslinging nonsense).

This actually reminds me of Tesla Motors’ regenerative braking system. Energy from deceleration is captured and stored for later use in acceleration. Genius!

In a battery-powered electric vehicle, regenerative braking (also called regen) is the conversion of the vehicle’s kinetic energy into chemical energy stored in the battery, where it can be used later to drive the vehicle. It is braking because it also serves to slow the vehicle. It is regenerative because the energy is recaptured in the battery where it can be used again.

Tesla Motors is an interesting electric car startup in Silicon Valley headed up by Elon Musk (of PayPal fame), who also started SpaceX and SolarCity (I’m an admirer!).

But I digress.

A BINARY STEP COUNTER?! OH MY! This is *amazing*, you have to see it. This reminds me of a rudimentary transistor, and how we keep cramming more and more of them into a piece of silicon we call a microprocessor, on top of which we have this thing called a computer, on top of which we have this thing called web two dot oh, … and ..
