The Segway Is Dead, Long Live The Segway

Before it was officially unveiled in December 2001, the hype surrounding the Segway Human Transporter was incredible. But it wasn’t because people were excited to get their hands on the product, they just wanted to know what the thing was. Cryptic claims from inventor Dean Kamen that “Ginger” would revolutionize transportation and urban planning lead to wild speculation. When somebody says their new creation will make existing automobiles look like horse-drawn carriages in comparison, it’s hard not to get excited.

There were some pretty outlandish theories. Some believed that Kamen, a brilliant engineer and inventor by all accounts, had stumbled upon some kind of anti-gravity technology. The kids thought they would be zipping around on their own Back to the Future hover boards by Christmas, while Mom and Dad were wondering what the down payment on a floating minivan might be. Others thought the big secret was the discovery of teleportation, and that we were only a few years out from being able to “beam” ourselves around like Captain Kirk.

Even in hindsight, you really can’t blame them. Kamen had the sort of swagger and media presence that we today associate with Elon Musk. There was a general feeling that this charismatic maverick was about to do what the “Big Guys” couldn’t. Or even more tantalizing, what they wouldn’t do. After all, a technology which made the automobile obsolete would change the world. The very idea threatened a number of very big players, not least of which the incredibly powerful petroleum industry.

Of course, we all know what Dean Kamen actually showed off to the world that fateful day nearly 20 years ago. The two-wheeled scooter was admittedly an impressive piece of hardware, but it was hardly a threat to Detroit automakers. Even the horses were largely unconcerned, as you could buy an actual pony for less than what the Segway cost.

Now, with the announcement that Segway will stop production on their eponymous personal transporter in July, we can confidently say that history will look back on it as one of the most over-hyped pieces of technology ever created. But that’s not to say Kamen’s unique vehicle didn’t have an impact. Continue reading “The Segway Is Dead, Long Live The Segway” →

Dean Kamen’s Prosthetic Arm

60 minutes has covered [Dean Kamen]’s modular robotic arm. This thing is light weight, adjustable for different body frame sizes, modular, and eventually thought controlled. The system is currently functioning quite well, as you can see in the video. Current testers are controlling it with buttons under their toes, but the thought control is in the later stages of development. Sounds like science fiction right? You can see a monkey using a thought controlled arm to feed itself grapes, though we don’t think it is [Dean]’s arm.

Another cool feature of this arm is the fact that it changes its grip on your body depending on how much weight you are lifting. Lift something heavy and it grips harder. Though it has a lot of the same information, there is a little bit of different footage in [Dean]’s TED talk about the arm.

It seems to us, with microcontrollers becoming so cheap and accessible that we should be seeing more home made contraptions in this area. Are any of you working with prosthetics?

Dean Kamen’s Stirling Engine Car

[Dean Kamen]’s company, the people behind the Segway, have created a hybrid car that uses a Stirling engine instead of a standard internal combustion engine. Stirling engines are closed cycle, meaning heat is applied to the outside of the cylinder walls. They are generally more efficient than standard car engines, but haven’t been used much outside of industrial applications. We suspect that the drivetrain arrangement is similar to the Chevy Volt where the engine is used to charge batteries which are in turn driving an electric motor. This is different from modern hybrids that can have either electric motor or gas engine driving the wheels. The article is unfortunately full of classic [Kamen] hyperbole and minimal detail. He calls the Stirling engine “an insurance policy” for the electric car since it can recharge the battery. That’s right, folks. If you run out of juice, you can put gas in the car. I doubt many Prius owners will fall out of their chair over that. Being a Stirling engine, we’d be more impressed if you could charge the thing by rubbing warm toast on it.
