Biomutualisms

I’m not sure the term is going to catch on, being a bit too attached to the biological, but Robert Full uses the term biomutualism to describe the way multiple disciplines working on related projects can create design inspiration greater than the sum of its parts. He explains it by way of an example in his own studies on gecko adhesives, and how his cooperation with other disciplines is resulting in breakthroughs in materials sciences, biology, and robotics.

There is some great footage here of new discoveries relating to tails and how animals use them for everything from self-righting to guided flight. A must watch for anyone designing robots.

Kinetic Sculpture Race 2009

We sent zogdo senior video correspondent and garden coach Genevieve Schmidt to the 2009 Kinetic Sculpture Race (Humboldt, California) and caught the above footage of the race. Humboldt County hosts this race every Memorial Day weekend, and it draws quite a crowd of bizarrely dressed spectators. Many of them dress like this on  daily basis. The star of the show for the second year running is the dragon built by Duane Flatmo out of hubcaps and similar materials. This year it has a fiery new trick, and it’s a real crowd pleaser. 

 

 

I had the pleasure of helping to make some of these possible, mostly by machining various gears and other parts. This is one of those races where if you are entering to win, you’ve already lost. Corruption and bizarre rules are built into the race so deeply that it seems clear they are there to prove the point that this race is about the journey and the fun,  rather than the finish line.

 

 

 

 

 

I’ve been to at least a dozen of these races now, and the quality of the entries and the size of the crowd varies wildly. I’d say the best one I went to was about four years ago, back when Yakima was still a leading competitor.They were connected with sculptures like an early variation of the Hippypotamus, which this year came complete with sage smoke billowing out of its nostrils. In the past couple of years, the race has vastly increased in notoriety, making the front page of Digg last year, and the front page of CNN two days before the race began this year.

 

Some of the new arrivals this year included The Octomom, complete with eight tentacles for grasping her young.

The Glory Hogs would occasionally stop to barbecue and hand out free hotdogs to their adoring fans. We got a great rooftop view of the race. 

I hadn’t seen this beetle (firefly?) before, but I didn’t catch its name.

 

 

 

 

 

The symbol of the race is the Kinetic Chicken, personified in this sculpture that arrived with great fanfare last year. It came into the race at the last minute with a huge entourage of chicken headed cyclists, towering over the crowd in chromed glory.

 

 

 

 

 

 

 

 

 

 

Also new was this skunk.

Quite a crowd of people follow the race on bicycles and skateboards, and give quite a representation of local color, like this dog, and this protester with a noble message about personal responsibility and smog reduction.

I’ll end here for now with a giant angler fish, a closeup of the dragon head, and a great show of Flatmo helping Twinkle light their star.

Update: Dead Man’s Drop and the dunes

All of the more interesting sculptures managed to make it to the sand dunes this year. 

I don’t have the weight specs for thedragon, but it’s nothing you want to be pedaling up a sand dune.  Here, the pit crew helps out a bit.

 

Dead Man’s Drop is a steep section off the back of a sand dune leading to a small trail through the trees. The dragon made it down safely, unlike Big Top (red and white in the  right corner of the picture) . A note to anyone considering purchasing a Flip Video Recorder: they have a nasty habit of suddenly dead batteries, which loses the enitre currently recording section of footage, however long it may be. It cost us a great film from right below big top as it rolled down the hill.

 

 

The spashdown in the bay:

We arrived at the bay to an icy windy day, spectators shivering in their down coats, while Zog, true to form showed up in a T-shirt.

 

This guy in the parking lot had his dog jumping through a bicycle tire ad nauseum; why? because he could I suppose. I have a cat that will retrieve thrown asparagus, but you don’t see me bringing him to perform at events.

 

 

 

 

 

 

 

The bay crossing portion of the race takes place with the racers going down a ramp into the 50°F waters of Humboldt Bay, many of them submerged to the knees in barely seaworthy craft. The most notable difficulty I saw this year was this giant picnic basket. As soon as it hit the water, we could hear loud cracking noises as something went horribly wrong inside. The side panel of the float (using the term loosely) was meant to open up as their escape hatch, but it was obstructed by the dock. Everything turned out ok, but I doubt they made it upwind with such poor aerodynamics and some obvious structural issues.

 

While it is more mechanically interesting than truly sculptural, I’ve been quite impressed with Twinkle (formerly The Patriot Act). They’ve had some time to perfect things, and what they have ended up with is a machine that made the race over land and sea both look effortless. I didn’t spot them in the dunes, so I don’t know how it fared in sand, but the back wheel is used for steering on land and as a rudder at sea, and those big wheels with the paddles on the sides really worked great.

 

 

 

 

 

The Flatmo Dragon took to the water like a swan. A terrible fire breathing swan of DOOM! A great improvemnt over last year making the headlines worldwide after capsizing. This has truly become a remarkable machine that would draw crowds in any event on the planet.

 

 

 

 

I’ll likely more or less end this post here for the season, but if you were in the race or would like to see more of a particular entry, I do have a lot more photos. Feel free to comment below.

Vibram Five Finger Shoes (reviews)

On the recommendation of Tim Ferris, we went out to our local sporting goods shop to see if they had any of the new Vibram five finger shoes in stock. We were in luck!

I’m a real shoe snob. I still scour e-bay daily just to see if anyone is selling my favorite shoes, not made since 2001. I don’t like shoelaces. I’m of the opinion that tying things to our feet really should have gone out of style with the bustle (I prefer to be asked if my shoes were made by aliens). My usual shoes are lightweight and form fitting running shoes, air padded, so when I tried on the Vibrams, I was expecting something similar with something scratchy between my toes. I was wrong.

I’d seen the pictures online, so when the shoe dude brought out a pair for me to try on, the first thing that struck me was the soles. They aren’t flat and ridgy like shoes, they are smooth and padded like the soles of your feet. If you push on the shoe from the inside, the soles split into tiny herringbone incisions (they refer to it as razor siping). These provide awesome traction. The upper felt like wetsuit material. Pulling the shoe on was easy except for the little toe. I’ve wondered if the shoe would be better of with only four toes instead of five, combining the smallest two, but I really think they just made the smallest toe a tiny bit on the large side. Once the shoe is on though, it didn’t seem to be a problem. The shoes are shockingly comfortable. I wasn’t expecting that at all.

Walking around in these isn’t like light running shoes at all. It feels like walking around in thick socks, but with the protection of a tough sole under your foot. I expected the wetsuit-like material to make my feet really hot and sweaty, but it really didn’t.  I bet these would be unbeatable on a rocky shore or tide-pool. They don’t seem like they would suffer at all out in the gritty sand either, since there isn’t really anywhere for them to chafe. I was trying on the Fivefingers FLOW model. They had another model, the KSO, which has a nice fabric mesh upper instead of the rubbery stuff. Trying these on took things one step further. I no longer felt like I was wearing thick socks, but more like being barefoot with tough soles. They are super light-weight and breathable. I bought a pair of the mesh shoes.

Wearing these toe shoes is such a pleasure that I found myself wearing them most of the day, around the house and in the yard. I don’t tend to wear shoes unless I’m going out, so this is a big seal of approval. After wearing them all weekend, I decided to wear them to work, which is about half a mile away. Walking to work, I took things a little slower than usual. The shoes didn’t hurt, but I could tell they were using a different set of muscles. When I got to work and sat down however, I felt a burning sensation across the front of the pad of my feet, like you might get from a few minutes of walking across asphalt barefoot. It didn’t go away, so I switched back to regular shoes for the day.  I think I was really close to giving myself a blister. I would recommend your first brisk walk in these be no more than a quarter mile with a day afterwards to see how everything feels. I have sore muscles down my calf and Achilles, and in my foot, which considering how much walking I do and how often I’m barefoot, surprised me. These shoes are marketed towards marathon runners, and I hear that you just need to adjust to them. It didn’t feel like a flaw in the shoe, except that maybe a bit more than the usual proportion of  stepping force is applied to the front of the pad. They don’t feel like they slip or chafe, and it would be hard to roll your ankle. I would say that as compared to normal shoes they vastly increase the pleasure of walking on natural terrain and indoors, and somewhat decrease the pleasure of walking on asphalt.

I’m giving myself a couple days off from the shoes to make sure I’ve recovered from the first outing and then I’m excited to wear them again, this time with no extended walks until I’ve worn them a bit more. I’ll update this post further as I break them in some more.

Update: After a couple of days of rest, I was able to walk a few miles over the course of the day with no ill effects. My first attempt at running lasted a coupe blocks before I could really feel it down the back of my legs and quit just to be safe. I ended up with sore calf muscles (in a good way). The shoes do put a lot more emphasis on lower leg and foot muscles while running. After two weeks, I’m now able to walk several miles at a stretch on asphalt without discomfort. I wore my five fingers shoes to the Kinetic Sculpture Race, and they were great in the sand. They didn’t pick up much sand, and since your foot doesn’t slide inside, there is none of that sandpaper feeling at tender spots on your foot.

I’ve been wearing them everywhere, and without socks. They do need to be washed often. I threw mine in the washing machine and they came out great with no sings of wear. I’m finding myself unwilling to wear my other shoes now, so I’m going to buy Vibrams to wear while my others are waiting to be washed. They don’t soak up much water when washed since they don’t have all the spongy stuff most shoes do, so I just wore them rather than drying them and it didn’t seem weird.

Update: I got a second smaller pair (to keep a good wash cycle going), and I like them even better, so if you can’t decide on a size, go with the smaller. Over the 4th of July weekend, I took the FiveFingers out to the beach and still had no problems with sand (they leave great footprints), and they were great for climbing on the rocks.

There was none of the pain of walking on barnacles barefoot, but none of the slippery feeling of being in shoes.

I also went out to the redwoods and walked around in the forest. My balance was much improved walking on small downed trees (the shoes wrap around instead of sitting flat like a platform). I found some stumps about twenty feet tall and had no trouble climbing straight up them. Making it up in running shoes would have been unlikely since there wasn’t much in the way of visible footholds. The soles were grippy enough to make it a breeze. I don’t know how they would be for hard-core rock climbing, but they are excellent for casual climbing.

Update: Took them out to the river and they were awesome for puddling around in the water. I didn’t try swimming in them, but walking on the normally treacherous slimy rocks was like a foot massage and quite stable. I also walked on some really scary looking blackberry brambles and none of them made it through to my foot, which I have to admit, really surprised me. I’ve been seeing a lot of people worrying about whether it is bad for your back or arches to run barefoot or in FiveFingers. I’ve suffered no ill effects now after several months. This is how we were designed to run. If you doubt it, just check out this video of an ancient hunting technique. I found it inspirational as a runner.

I know a lot of you don’t live near stores where you can buy Vibram Fivefingers, and most of our readers are international, so I’m posting an amazon link (international variants at the bottom of the resulting page) which I still find to be the safest and most convenient, but I’ll keep an eye out for better deals and post them here as I find them.

There are several colors and styles. I went with black mesh KSO (pictured). The well placed strap system makes them flexible enough that being a size off shouldn’t be a big deal. These are listed in European sizing, so I’ve put up a sizing chart, which I found to be quite accurate.
Here you can find Assorted Vibrams available on amazon. Scroll down to the bottom of the amazon page to find them for your country if you don’t live in the U.S.

Robot Penguins: Festo does it again

 

Pengiuns sure do seem to be getting a lot of play in recent years. Festo has now targeted them for their latest aquatic and lighter than air robotics. They seem to be doing two versions of these, just like they did with their Robotic Jelly Fish. in their latest promotional video, they show off aquatic penguin robots which use sonar to navigate and communicate, some Mylar, lighter than air penguins reminiscent of that awesome Fin-Fish by LaChLuVe last year, and several other projects involving biomimicry and affordable rapid prototyping.

Update: Here is a video showcasing the air penguins

Update: And more footage of the robotic sea penguins:

Update: PDF file for the bionic aqua penguins with detailed specs, capabilities, and photos.

Festo Air Jelly

Predating the LaChLuVe fish is this Air Jelly made by Festo, a German automation company. The unifying goal of these creations is to achieve neutral buoyancy. From there, propulsion becomes as effortless as it would in zero gravity. This jelly uses helium for buoyancy amd when deflated, weighs in at 1.3 kG. A  Li-poly battery as its only power source, and a series of gears, shafts, and cranks power the arms. It can be steered by control of a pendulum on the underside.

1.3kg gets you a lot more to work with than it used to.

LaChLuVe Air-Fish Captivates Airship Regatta

Last week in Friedrichshafen in southern Germany, there was an airship regatta (race). Along with the usual group of speedy nearly uncontrollable little blimps was this beauty which will be sure to be getting a lot of attention in the coming weeks. Team LaChLuVe has set the bar so high with their Fi-Fi- Fin-Fish that the airship races will never be the same, and may have a lot of new applicants. Unlike the propeller driven blimps and zeppelins, the fish glides through the air propelled by a very natural looking swish of the tail, which also provides steering when holding it in place and gliding. The pectoral fins are servo actuated for additional control. I would be shocked not to see this as a consumer product within the next couple of years, and I can’t wait to see what shows up at the world air games next June.

Update: The Fi-Fi- Fin-Fish was made by Empa (a Swiss materials technology development institution) by using electro-active polymers to power the motion of the tail. When electricity is applied, the polymer contracts like a muscle to give the tail its kick. The fins, in combination with the low center of gravity, do a great job of keeping it upright. There is a further abstract for a more complex system with a flexing body here. A flexing strip along the top and bottom of the fish would be attached to the vertical ribs. The contraction of the polymer would cause the body to flex in a more natural fashion.

Update: The project was a collaboration with the Technical University of Berlin, and has been a several year project. Earlier versions of the fin-fish flew in the ‘06 and ‘07 regatta. Empa started with a more traditional airship, and got more fishy with each revision. Several tails were tested, as were several different ways of using the electroactive polymer.

 

 

 

Part of their vision is creating a solar powered version that could operate efficiently and silently for surveillance. There is a growing demand for spy drones, and most of their competitiors sound like flying weed-whackers.
