OWI Robotic Arm Edge – You can use USB interface module to connect it to PC. Unfortunately official software works only under Windows and do not provide API. I have been able to reverse engineer their USB protocol and write sample code which allows to control the arm from Mac and Linux.
This is USB device with vendor id 0x1267 and product id 0. The device is controlled by 3 byte commands sent via USB control transfers. Command format is byte0, byte1, byte2. Each byte controls a group of arm features. All motors could be controlled independently. Most commands start action which is continued until next action is signalled. Byte ’00’ universally used as stop action.
