I came across these two wooden bots and thought it might be of interest to others on the forums.

The first is a "Wooden Robot Arm" on youtube here is a link

And the other is a full Mech suit here is a link for it:

    Wow that arm is really neat! It is more detailed and interesting than I imagined it would be.

    The suit made me think of the Wicker Man for some reason.

    Attached is a pic someone sent me several years ago of some wooden tracks he had made.

    Amazing find, thanks for sharing.

    That arm is just as impressive as Tomy's 1980 Armatron, which used only one motor to power all six axes through joystick-controlled mechanical clutches. Even more amazing is that 4 of the axes had two speeds. Like required reading, everyone who's into robots should be required to own one of these and study it for mechanical cleverness. Incredibly complicated, it is the brainchild of a single mad genius at Tomy. He designed & built it by hand.

    The wooden robot arm looks like something Charles Babbage would have built.

    The Armatron was awesome and I wish I still had mine! My first attempt at a robot project was to hook the Armatron to an Atari 400. I glued potentiometers to several of the joints and feed their outputs into the Atari's joystick ports. These ports could also be used for digital outputs to trigger solenoids to move the levers. For two of the joints this approach was viable, but the wrist joint required a rotary encoder which was beyond my ability at the time. I didn't even have a plan how to handle the shoulder joint as it wasn't amenable to either approach. I put the project on hold and misplaced the Armatron along the way.

    I'd like to claim genius on my part, but I got the idea from an Analog magazine article which is now online: http://retrobits.net/atari/armyouratari1.shtml

    I think it may have been a reprint by 86 because I know I did this when I was still in my teens. The Atari was a great hackers home computer and greatly underrated. There were people controlling servos, steppers, and other cool stuff. I figured out how to controller a plotter! The 6502 assembler was nasty but I eventually got good enough at it to be paid writing code for it.

    @erco: Do you own one of those Armatrons? Also, I think it was you that was ordering some kind of robotic arm kit (seems like a year ago). How did that work out?

    P.S. a lot of those large-scale tank builders fabricate their tracks from wood.

    @Mikerocontroller: I do like robot arms and I have them all! A few Armatrons, a mobile Armatron, two OWI Edge robot arms, and a Quickshot. They're all fun, but just manually controlled toys. Per Martin, it's a lot of work to add feedback pots to any of them for closed-loop control. I know OWI sells a USB interface that "plugs right in" to their Edge robot, but I assume it's still open loop control, it probably uses timing commands since there's no way to know where each joint is. The Armatron is even more work to automate, as you would have to add a servo or motor to move the joysticks, which mechanically clutch and drive each joint. Ingenious for what it is, but not a great platform to hack unless you totally remove the joysticks and clutches and add 6 new motors and bypass all the overload clutches. That's also removing the most innovative part of the whole toy.

    One of my favorites is the OWI Kabuto Mushi robot. It's basically an IR remote controlled treaded tank with a claw that closes and lifts.

    The Armatron is a really neat looking piece of work. Is there an authoritative database for electromechanical toys of the 60's, 70's and 80's?

    Authoritative database? Not really.

    Colorful coffee table picture books? Yes.

    A friend of mine worked for Tomy back when they made the Armatron. He owns a very rare all-transparent model that clearly shows the inner workings in all their glory. Very cool and priceless. I'll·try to get a pic.

    Boy this brings back memories. I got one of these as a Christmas present when I a kid. Probably in the early 1970's. It was VERY fun to play·and was·a key contributor to my love of·Robotics.· (thanks Mom !)

    · Perfect for pouring Plastic Goop in Thingmaker molds.· Anyone remember the X-15 Trike?· One toy I never got to see in action was the vacuum forming kit.· The plastic Unimat was cool as well.. starting to ramble like Larry King....

    I've got a mint Vac-U-Form right here ! X-15 was also very cool. All those old Mattel Toys were great (I'm biased).

    Anybody have or remember:

    Mattel's Injector (kid's injection molding machine)
    Spinwelder
    Kooky Cakes
    Incredible Edibles
    Strange Change machine (memory plastic dinosaurs)
    VertiBird helicopter
    SuperStar free-flight airplane (first use of Ni-Cads in a toy)
    Hairy Canary stunt plane
    Major Matt Mason

    Wow! That brings back memories. (As I recall it had only one motor.)
    I had a college professor who interfaced one of those to an Apple//e. He did it using bicycle spokes attached to solenoids. These hooked into the base of the joysticks. Rube Goldberg would have been proud!

    I do remember the Major Matt Mason stuff. My brother had the space vehicle (the one with dual rotating "spokes" and tail dragger). He also had the alien pal with the translucent green head. Does Mattel maintain a museum of their past toys? I still remember the Christmas when I got the California 500 Sizzlers track. My brother received the VertiBird. Mattel always had the "must have" toys.
    Of course, every generation has their favorites.

    I remember the SpinWelder. Got it for Christmas but my step dad and hired hand put together the dragster. I was none too happy about that!

    You didn't mention the Big Trak!

    Also in the late 70s I had this large foam airplane, like a big glider except it had an electric motor in it that was charged up by a 6 volt lantern battery. It wasn't the SuperStar.

    Here's a write-up about the Mattel Thingmaker I found on the Net:

    "A Thingmaker behave consists of a program of die-cast metal molds, into which are poured a liquefied chemical center titled Plasti-Goop, which came in whatever colours and varieties. The modeling is then blistering atop an open-face automobile blistering bag oven. The Plasti-Goop is well by the heat, and when cooled, is distant from the mold, forming solid, elastic replicas.

    The construct of the Thingmaker was actually introduced in 1963, as conception of Mattel’s “Vac-U-Maker” set. This omnibus behave compounded the newborn “molds and Plasti-Goop” profession with the existing “Vac-u-form” machine, which formed ultimate sculptures by vaporisation anorectic sheets of plastic, then using a clean viscus to modify the soft impressible over hornlike impressible forms. Following this launching period, the Thingmaker assets was “spun off” as a removed set, and the “Creepy Crawlers” distinction began in earnest"
