• Actuators / output devices: 2x servos
• Control method: Picaxe18x
• CPU: picaxe 18x
• Power source: 4x AA batterys for servo, 3x AA batterys for picaxe
• Programming language: Picaxe basic
• Sensors / input devices: none (yet)
• Target environment: indoor

 I'm yet to put any kind of grabber on it, and the pan still needs some work. but I think its neat enough to warrent posting online. Actally, its been this state for a while, and i've had it on my blog here: http://diydata.wordpress.com/2008/12/31/simple-meccano-robot-arm-redone/ for a while

Its controlled by a Picaxe 18x, with 2 servos for the arms, and currently one electric motor for the rotation, however, it pans rather fast, so i'm thinking of getting a servo modded for continuous rotation, and using that to control the pan of the arm

I'm also planning to eventually add a gripper, likely operated by a micro servo

another thing I wouldn't mind adding (which shouldn't be hard either) is some potentiometers as controls for the joints

so i can see a bunch of various sized servos coming my way for modding, and other various projects.
