    I am pretty impressed by your demo!

    A few questions, please:

    Are those are servo motors or steppers?
    How are you 'teaching' the robot? Lots of trail and error or does the robot record a movement and play it back?

    Thanks, IJ. Using 6 servos here. I can either hard code it (trial & error) or use an IR remote or keyboard as a teach pendant and use record & playback modes. Lots more impressive stuff to come. Built the arm for a PICAXE feature in upcoming ROBOT magazine, May June issue, due out in March. Part one of my series is on newsstands now, a basic intro to PICAXE.

    Programming scripts using an IR remote as a teach pendant:



    And here's a link to my keyboard demo since that post is long buried in the active forum:

    Thanks, IronJungle! I was pleasantly surprised at the arm's accuracy. The PicAxe is a great controller for this project.

    BTW, the miniature 5/8" wooden alphabet blocks I used are quite handy here and in other projects, robotic or otherwise. They are available at a discount (for $3) if you mention ROBOT magazine when you order at http://www.helpinghahns2.com/product...ocks-small.htm One set is 15 two-sided blocks. You need 2 sets for one full alphabet.
