Hi i'm a newbie here and i have a doubt,

How can I use the movements I do on a modeling software (3ds max, or similar...) onto my real robot, the IK.

I want to program my robot with Inverse Kinematics, Could you give me a clue on how to do it, can I use the methode(?) exposed above. :roll:

Thank you very much :D

sorry by my english, it isn't my first language but i'm trying to improve it! hahaha :)

Personally i would use Blender (free open source software http://www.blender.org)
it does 3D modeling and inverse kinematics (IK).
Real-time control is handled by the Blender Game Engine. Although i use blender for 3d modelling im not familiar to using this in Blender myself, i have seen loads of examples, so finding more info will be quite easy.

A Python 3.2 (http://www.python.org) script (Blender 2.59 comes prebuilt with Python 3.2) runs inside of Blender and continually sends joint angles to a socket port.

A Processing (also free and open source software http://www.processing.org) program runs as a socket server and recieves a string of angles from Python.

Arduino Uno (open source microprocessor board http://www.arduino.org) recieving commands from the processing sketch through a USB/Serial Port connection.

Thank you very much, now i have a way to follow. But do you think i can use otherboard than arduino? Because i already have an devantech sd84 servoboard it has to be arduino ir i can use my own thank you for the priceless and extremely useful information you gave me :D
