If you have a an RS-232 interface (2400 or 9600bps) you might consider a kit from Lynxmotion ( http://www.lynxmotion.com ). They sell various robot and robotic arm kits that utilize hobby R/C servo motors. Scott Edwards Electronics and several other companies sell devices that allow you to control up to 8 servos per board. You'll have to write all of the software yourself (sending commands to identify a servo and a position value).
