A friend of mine asked me to help doing a stage design for a dance project, which needs to control 4 ropes with servo motors. A good time to finally use the arduino diecimila i have lying around ^^
We are working on a processing sketch to simulate the movements of the ropes, from this it will output four speed values which should control the movement of the ropes. The motors should be continous rotation servos that should able to rotate in to directions.
I'm quite new to this whole electronics thing so i had some questions:
the motors would be hitachi servo motors (see spec in reply)
Those look like industrial servos that use a completely different protocol from the hobby servo libraries that are available for the Arduino. The datasheet indicates that they are driven from a Hitachi ADAX4 motion control module – these modules look like they can be driven from a pc (probably through RS-485). If you do a search on ADAX and Hitachi you can probably find more information about the protocol.
