shodai:
I have a Fischertechnik robot arm (3D-Robot 9V) and I am wondering if it is possible to use an Arduino (ideally Uno) to control it?
Quite possibly. Do you have a link to more information? What you gave is only a sales web site. I see it operates with a 9 volt power supply, so that is compatible. What connections are possible with the devices controller box?
