Disney Does Linkages

All I've seen lately from Disney is their princess movies with our twins, but Disney has been busy doing computer analysis of gears and mechanical linkages, which interests me greatly. Anyone who wants to build a walker someday may delight in this new video. Nice software traces point paths as gear diameter and location varies. WANT.

    That is simply amazing! Shows what you can do with a big enough computer, and a laser cutter, and a CNC mill, and a 3D printer, and.....:thumb:

    That's really cool! What a clever way to go about solving that problem.

    Their daytime jobs look like as much fun as yours!! :smile:

    Outstanding!

    I like they way they can make figure 8's. Maybe some gearing for a BOEBot? :)

    Capital idea, an improved Boebot Walker kit!

    Cool.

    As a way of animating creatures in your movies CGI all those external gear models may work.

    Otherwise it looks like Victorian animatronics from a centuary or more ago.

    The heck with WANT. MUST HAVE! Is software like that available anywhere? Even without the optimization, just the simulation part would be useful.

    @erco - AMAZING!

    This linkage from W9GFO's links would make a interesting walker....Couldn't these be opposed for a four legged walker with rotary drive? (If you had a way it wouldn't fall over...)

    Amazing!

    One problem, though, is that this optimizes the design for one 'phase'. you have the 'walking' phase, but not the 'starting' phase. And you can't just speed it up to turn it into the 'running' phase. (and you can't have a 'big cat' model that can't run. That's just... not right... )

    A 4 legged walker bot? Might be interesting to play with.
    but what I really want to see is a 2 legged walker like the AT-ST from Star Wars.
    (Well, maybe not that spindly legs... it would need a weight to shift around as it walks, to move the CG over the foot that's on the ground, accellerometers and stuff... A Propeller should be capable of controlling it, I think)

    Hi Phil, You could check out this youtube also - invloute gears with curve points like the disnaey animation stuff, used to represent a guy pushing agianst a wall - http://youtu.be/rgy1J7iX9_Y
    So yes, ther simulation part is possible it seems!
