Absolutely brilliant! You’re right, the concept is simple, but the design is awesome!!! Beyond just the technical, you really kicked up up a notch with the presentation. The aesthetic design is amazing. It looks like something that you can sell right out of the box. A very cute robotic bug my daughter would love to own. Great work!

Thanks Eric,

Yeah it's simple, mostly because I lack the skills to pull off all of the stuff that you guys do... I just make do with what I know and have... this is the first time that I had a stupid idea, and was able build it without having to go out and search for the parts... had all of the r/c heli spares sitting here :) And yeah, aesthetics are very important to me, probably too much so. I had another servo for the head, so it would tilt, compensating the tilting of the body.... but it raised the head up way too high, and hated the "look", but it functioned well. I also tried to put a head lock gyro on it, but no where to put it where it wouldn't glitch from interference in the tight package.

Anyway thanks for the kind words.... it's nice to work on a simple project for a change :)

That is beautifully executed, and adorably cute! I love it! I love everything about it with one tiny niggily exception - if I'm not mistaken, you're using airband for a ground device. Very naughty. But I understand, and at the risk of losing my license, I forgive you. :)

That thing is just way too cute not to forgive anything of - I'd buy one today if you marketed them!

Can I vote you enter that in the contest? It's just way too pleasing not to be a contender.

Thanks :) And it's spektrum 2.4ghz... although it is made for air, it is ground legal. Spektrum also makes other 2.4ghz tx/rx that are used for r/c car races, which uses the same technology but with just fewer channels.

Aha! I stand [sit] corrected.

2.4ghz is the catchall band. It's fair game!

Ok - so it IS perfect in every way!

Way cool work Crabfu, congrats on this!

Yes, it is simple, but that's a very good thing. It shows all of us that it might do us some good to take a step back and rethink how we build robots sometimes. Robots don't have to be the overly complex things that they are to accomplish incredible things. Us engineers tend to have a common trait to "overthink" a problem:D Matt used to yell at me all the time for that!



aesthetics are very important to me, probably too much soI admire that quality! As I'm sure you can tell, this quality is a bit lacking in robotics, haha;)


BTW, I know you mentioned a lot of the details of your robot in your video, but do you mind putting them in this thread as well? It'll definitely help your score come July.

Oh yeah, I almost forgot. I got you entered in this contest!

Thanks Alex!!!

And not sure what to mention about the swash, so I'll just list off parts you need here:

-4 micro servos. Standard size would be fine too, I just happen to have a lot of spare micros. It will be rather small and light, so you don't need anything fancy.

-lots of long servo horns. Each servo you buy will come with a lot of these... but you need the long ones. I think the long ones that I am using came from hs45HB's

-a r/c transmitter (tx) capable of eccpm, these are made for cp helicopters, and control 3 servos for the swash at 120 degrees. And as Adrenalynn pointed out already... to be ground legal it should be 2.4ghz. What I am using is a spektrum dx7, which I use for my steambots & helicopters :)

-rx that matches your tx. With 2.4ghz, only one tx can be bind to your rx :)

- one receiver pack - when you buy a radio system, it usually comes with one of these. It should be 4 aa cells to power servos... or equivalent rechargeable.

-servo tape, just tape on the servo to the pack

-helicopter ball links... I am using align trex 450 helicopter links, but just about any heli links will be fine. You can adjust the links to the correct length... trail and error until you get nice movement in the servo horns/legs.

-body... you can use whatever :) the head I am using one of those 50 cent capsule toy vending machine things... the wings are align trex heli tail blades. The body is from a canopy from some rc plane that I had forgotten where it came from :)

-led eyes are from micro heli as well... they have servo plugs and can be switched on and off via any channel- just set the end points on your tx to 100 or above.

That's about does it I think, pretty straight forward & simple. But feel free to ask questions if you guys are going to build one :) The hardest part is programing the tx, if you are a rc heli pilot it will all make sense to you - it literally acts like the swash of a cp heli. If you don't fly, it may be confusing, and the initial cost for the radio can be rather high :( The actual robot itself, minus the raido tx/rx, is cheap though, most expensive components are the micro servos, at 10-15 bucks a pop :)

Thanks guys... coming from an animator/artist background, illusion of life is what I try to accomplish with everything that I make. Comments that are especially important to me are those describing these lifeless machines as having personalities.... it is means much more to me to have a kid smile and say they "he" is cute, then to have someone marvel over the tech or work behind it. This happened to be a very simple project, but achieved just about as much fulfillment for me as ones that took me months, lots of planning, building, and redesigning.

So thanks for the kind words guys :)

Crabfu.

Your 3 legged swashbot inspires me! Using simple 50 cent egg shells from toy machines for the head is great! I looked at your video several times. I almost laughed out loud when I noticed you were using a rubber servo mount for the foot on the back leg.

Your project gives me hope... I have been a little overwhelmed by the contest entries where people produce thier own parts with machines that I could never aford. Your controller is a bit expensive, but that's ok.

Sir, I hope you win this seasons contest. In my mind, you deserve it.

Cool... yeah the back leg needed some traction for walking, but the other legs needed to be sliding for turns. It does neither well lol. I had silicone tubing for the back leg at first, but realized the little servo mount had a tab on it, which made for slightly better grip.... just making use of stuff I had laying around :)

Yeah a good heli transmitter is not cheap... I fly r/c helis too, so already had the expensive parts... actually everything was made from stuff I had, first project that I didn't have to buy anything for :) Programing the transmitter can be a bit tricky if you are not a r/c heli pilot... so if anyone is gonna make one of these and need help with the transmitter settings, just let me know.

With the success of this lil guy, I decided to make a bigger version based off of the same principles. I've started building it... and got most of the hard parts worked out now, just need to finish up and somehow make it purdy. Will post when it's done :)

Thanks again guys for the kind words everyone!

He was trying to eat the antenna.... funny thing is that the cat is really afraid of servo sounds... robots, helis, even scared of one of those tiny toy r/c 3" cars. For some reason he wasn't afraid of swashbot, so I took the opportunity and grabbed the video camera :)

Update... I started building a bigger swashbot, with standard size servos & custom legs etc. I added 3 servos for the head... one for normal yaw, and 2 others to compensate the tilt of the swash/body via mixing aile with one, and elev with the other. It's subtle, but adds a bit of life to the head. Of course the head is just a servo box right now lol.... will be pulling my hair out next trying to figure out how to make it purdy :)

It now has 3 standard size servos for the legs, and 3 micros for the head, and added a 6v 1200 receiver pack. now with this combination, was able to get rid of the inchworm movements, so the body never touch the ground, in fact it can't :)

Thanks :) Unlike Seinna's tripod, I can't say that mine "works well" :)

But it's rather fun to build and control directly. It requires a bit of practice and coordination, if you fly r/c helis, it shouldn't be a problem. Otherwise I think there will be a bit of a learning curve on the controls... the second version does fall alot, since center of gravity is quite high (which is needed for the turning), and not being able to use the body for inchworm kind of locomotion. I'm still programing in the transmitter and learning how to make this little guy move well.... as well as experimenting with different surfaces and leg tip material... it needs to be grippy enough, but also smooth enough to be able to turn. Anyway thanks!

04-24-2008, 11:54 PM
OK finished SwashBot2.... I went back to inchworm movements, as it was falling way too much, and not reliable enough when not using the body as support. Turning still works on the tips of the feet only, but walking in all directions are now back to placing the body down.

Thanks for explaining the origin of "swash." This is a fabulous toy -- I wish I had one!

Since you are a 3D animator you'll appreciate this. The artists working on Jurassic Park studied tons of slow-motion film of predators running after prey. Their main observation that was obvious from all the film was that even as a cat as flexible as a cheata ran at full speed, its head and eyes stayed perfectly level. And yet when they tried to apply that to running dinosaurs it looked too "fake."

I think it's the head compensation motions that makes your bot look so "alive."

Thanks.... yeah after making the first vid, I realized that most people don't know what a swash is, so the best way is to show it. CP helicopters are really a mix of complex mechanical linkage, and elegant system of computer servo mixing :)

And about head.... yeah I've done a cheetah run cycle years ago, and when I had it perfectly still it did look fake :) Anyway the head compensation on the swashbot2 is subtle, but animation & illusion of life are all about these minute subtleties... It was very important to me to add 2 extra servos that barely rotate. When I mixed the servos in more, so that it was more obvious, it was cool but stood out too much.... in a good animation, you should never notice these subtle things, only animators can usually pick out what has been done. And with this swashbot, I'd assume that only you robot guys would noticed stuff like that :)

It's definitely the head motions that make it so expressive. Without that, its "gait" would look more "tragic" than "cute", imho. It's the head motion that *makes* these bots.

W.A.L.T.E.R. has an arm. Does arm motion count? It has two sensors (and more will follow) and a gripper.

Thanks! yeah I was talking to make about steambots a while back. This would be a lot easier... if I knew more about making products, it would be a neat kit :)

Thanks for the comments about the body work... it's all done by hand with that shape lock stuff, so it's not as polished as I'd like. This stuff is like hot glue gun stuff, kind of hard to get detail, and can be challenging to work with at first... really need a mold or something, I wanted to do a lot more with it, but given the material this is about the best that I can manage. It looks nice in the pics, but is rather ghetto when you look at it up close lol.

Part of the attractiveness of something like this built into a kit is that it is raw and each one takes on a personality. Art mimics life. Crabs aren't all perfectly formed either. ;)

That said, you would need a mold to produce any real volume. But there are mold making products out there that are cheap and super easy. Your crab-bot is simple enough that you wouldn't need to injection-mold the plastics.

beauty marks... lol I have a hole on the top shell, from running a hot battery right off the charger lol, it melted a small hole. Also areas around the servo are open like that because of the heat from the servos... these servos run hot, as I'm working them a lot, and shapelock melts pretty easily. So some of the beauty marks were not intentional, was thinking of adding a band aid on it, would be cute :)

Thanks! The idea.... well I fly r/c helis, one of my other money pit hobbies :) So got the idea while setting up the swash of a heli one day, the swash was organic in movement, and direct control is something that is missing in a lot of the r/c robots..... I love the complex motion of a humanoid robot, but you program it and then you hit a button and watch it performs a move. I hate that :) So I knew I wanted to do something with a the simple, yet complex system of a ccpm transmitter programing for something outside of a r/c heli. My first goal was just to have a robot thing, or kinetic art piece maybe, that uses the swash system of a heli, but didn't expect that it could perform any sort of locomotion. After playing around a bit with it, with spare parts I had laying around, I realized that it's possible to make it walk & turn.... not very well, but hey it working at all was a nice surprise for me!

Anyway, I don't know much about this robot nonsense, but what I am good at is coming up with ideas that is a bit outside of the box, the type of ideas that are so stupid that it doesn't occur to most people :) So I just make best use of what I have & know... which isn't much lol :)

Jets.... Now that's about the only thing that is more of a money pit than helis, steam, and robots! lol :) So you probably have a tx that is ccpm already, and spare servos.... build a swashbot!

the best way to learn is to learn the hard way, but i am using completely different horns for the legs, this whole project has cost me $415!!! but i know that the transmitter did it and is re-usable which will definately give me more bang for my buck,
i will post my shoddy knock off wen im done!

I can't tell you how many kids (and kids at heart) has been bugging me about every single little detail :) I thought making a build vid would answer the questions, but it only brought out more and more lol. Anyway, sorry to hear that you are learning the hard way.... I took for granted that not many people who want to build a swashbot, are into r/c and helicopters, so I may have barely covered some of the areas that would be hard for a non r/c heli person to grasp... sorry!

Anyway keep us posted, would love to see your progress, and try to help :)

I would love too!

I think SwashBot is one of the coolest robots I have seen. I'll have to go back and look at all the stuff Crabfu has posted about SwashBot and see what I would need to build one. I have an almost 3 year old kitten named Doozi I would love to see interact with SwashBot. I hope SwashBot isn't too expensive to build, with exception of the body, which I would have trouble making. Small servo controllers seem to cost more than an SSC-32 though, which might be too large to put on a SwashBot unless it was made a bit larger.

To be on the internet, a SwashBot would need some sort of main controller that can handle WiFi. It could be something like a Hammer, which can run full Linux. I already have WiFi working on Hammer, but need to get a new WiFi router (next month, I hope, if all goes well this month). The new Hammer-RDP (Robotics Development Platform) that's being developed by TinCanTools, myself, and Sienna (she's doing all the real schematic and board design) might work real well for this sort of thing.

The main thing, is a having a processor that can handle TCP/IP (This is what the internet uses) networking. Many ARM7 processors and others can handle this, so it does not have to be ARM9 (Hammer and many others).

I have an old Scenix development board here. TCP/IP, built-in web server, email server, PPP, and it has two serial interfaces. It COULD conceivably drive the servo controller over serial just streaming commands from the 'Net. And it's only 1.6"x2"

How about using AX12's? You can control them from the serial bus, right? No servo controller needed, right? [I have zero experience, I'm just going from hear-say. That would save tremendous size-and-weight.

Yeah the transmitter is the main cost of a swashbot, it is sort of the brains of it all. Outside of the fancy helicopter transmitter & receiver, the parts are cheap. Servos are around 10-15 bucks a pop, links are I think around a few bucks, balls are around 10 I think, and battery packs are like 5 bucks etc. Anyway, you can bypass the ball links too, if you custom made the legs.... links are just what I had laying around as spares for my helicopters, and they are adjustable so it was easy for me to test and put together. Basically it's a simple parallel linkage, and the links can be replaced by just a plate.

So... yeah, I guess with what you guys are thinking of doing, it won't be using a heli transmitter, but AI, so just the 4 servos, legs, battery, as the main parts... then add your mumbo jumbo cool stuff to control the servos :) The cost should be low, for a robot anyway only carrying 4 servos.

btw the balls were like 36 bucks thanks to those special kind of long ball thing

Yup there is only one of those in the heli, so each links pack only contains one. However, as I've mentioned to you, but figured it would be good to post here for others who my be interested... you can buy only one pack of the balls for the Align Trex 450, and cut a small piece of metal tubing to form the long ball links, and use long bolts for those. That way you just use the balls themselves, and the long part can be made with only one of the ball link packs :)

The good thing is, now you have lots of ball links to make something else with, they are useful for future projects :) or get a heli now that you have some spares lol.

Cool, yeah Trex 450 SE is probably the most popular heli right now, so you can find the parts at just about any r/c hobby store :) The good thing about the hobby store is that you can look and compare sizes and such, making sure that things will work instead of ordering the wrong parts or something.

also you will need servo horns that fit your servos,
you can see in the video what type of horns youll need
im using the servos that come with the transmitter,
im using these horns,
http://www.unitedhobbies.com/UNITEDHOBBIES/store/uh_viewItem.asp?idProduct=3752
and you know the screw that links the horn thats mounted on the servo to the "leg" servo horn? you can use any nut and bolt that will fit
you can find ll of this stuff at hobby town usa i learned that this sunday,

Cool!!! Well unfortunately I don't think that particular system will work for a swashbot... you'd need a ccpm system, one that works for a heli. BUT.... that 4 ch system will work just fine for a tortoise, the flapper fish, putter bot.... and a ton of other creative ways to use a few servos :) Cool thing about an r/c system hacked to make bots, is that there are no programing involved, just servo tape a bunch of servos together and see what happens... you'd be amazed how organic you can get things to move because stick movements are proportional, fast, and fun to learn how to control!
