    Aloha!

    I've just finished my first run at animatronic hands. I'm working towards using these in my upcoming G1 Transformers Devastator stilted costume build.

    Here's the reference picture I worked from:

    Here's finished pics:

    And here's a short video:

    There are a lot of edits to make for the next prototype version:
    -A gear for each finger so I can fold a finger all the way
    -Repositioning of the eye screws to they don't hit each other when folding
    -Permanent attachment of rings to a glove
    -Adjustment of line lengths
    -Mini-wedges under each end of all toggle bolts so the fingers straighten when not under tension
    -3 joints vs. the existing 2. I saw a comment against this working, but I'll have to try it to accept that. =)
    -Later on, hardier materials will be used of course
    -Bottom enclosure of lines, creating square finger effect
    -Editing of the starting position of the thumb & its mounting

    The final version won't have my hand so close in behind the assembly - more like 1-1.5' back. Also, the hand will be mounted to a wrist in the robot's arm and thus be supported.

    What are your thoughts? How might you approach this? What changes might you make?

    Thanks!

    I'm tryin' somethin' similar to this for my Jazz's hand just in case I can't use my own in my stilted madness that I'm totally gonna kill myself in.

    Thanks!

    What manner of stilts are you planning? If you search my posts you'll see I'm planning to use stacked hard insulation foam + calf reinforcement.

    For an update on my hands, here's the V2 hand prototype. =) http://www.therpf.com/showthread.php?t=241468&p=3678639#post3678639 I've been busy lately but hope to move on V3 during the coming long weekend.

    The V1 torso harness system prototype has to be started soon as well, and I expect that will be a time consuming one. I want to have the 'skeleton' of major features working for Halloween, though it would be 'dressed' as a much more simple costume for that.
