    Attacknid, a toy hexapod Mech warfare style

    I'm pretty sure many of you have already heard of them. I must say I'm impressed they managed to produce a hexapod as cheap as this. I'm convinced this isn't a real 18 DOF hexapod but it moves pretty well even if the gait algorithm is pretty limited. But it can walk in any direction and the turret on top rotate 360 deg.

    I'm pretty sure many people will find real Mech warfare interesting when the entry level is as low as 70£!

    This is the very popular sneak peak:



    I might buy one (or two) myself for my kids..

    I think he uses cam-driven walking? But I've not studied such mechanisms to have any idea how one makes it omni-(hexi-?)directional.

    It's nonetheless a ridiculously cool piece of work.

    So let's say it walks in the direction of the turret -- that's one motor.
    And then there's a motor to drive the cam, however it is constructed.
    And then there's a motor to drive the firing attachment.
    That makes for 3 channels controlling 3 motors.
    Now, what's the construction of the cam/link system that can walk the six legs in the direction the turret is facing? Anyone care to guess? :-)

    Quite tempted to get one.

    His website might hold some clues as to the linkage, especially the Big Bug and Spider Tank:

    Note in particular the triangular linkages connecting the alternating sets of legs (seen easiest in the Spider Tank video). I'm straining my eyes a bit, but I'm only seeing two motors in the Big Bug video? If so then that's extremely impressive.

    And for those who haven't seen it, also check out the giant one he's making.

    Here's a video of the early prototype. http://www.youtube.com/watch?v=_6qpSOjtB2E&feature=plcp

    A Chinese company has already cloned the design, you can buy a mini version from radio shack.
    http://www.radioshack.com/product/in...uctId=11077835 same thing on a super small scale.

    Either way good for him for getting a toy company to pick up his design. This dude has some crazy youtube videos.

    Are you sure the "hexbugs" are the same thing? The "hexbugs" my kids got a year or so ago all "walked" using vibration and anisotropic friction, rather than any kind of leg-lifting action.

    Hexbug is the "company" name, there are five or six different styles.

    Ok, got my Attacknid yesterday.
    It is a fun toy. Once the quad is up and running (I am waiting for another shipment of xbees - I broke one from my quad kit), I will be using the Attacknid to run attack simulations and for general target practice.
