I have two servos which cannot be hard wired directly to the EZ-B controller. They will be located about 10 feet from the EZ-B and I can't run wires to them. These servos will be controlled by the script running in the EZ-B using information from the camera input. Can I use a wireless device like an xbee to connect the servos to the pwm outputs on the EZ-B? Has anyone ever tried this or has suggestions as to if it can work?
