Yes, you can plug "traditional" servos into the motor(/PWM) outputs on the EduRobotics RC. Use a regular 3-wire PWM calbe, and just be sure to connect the PWM cable to the PWMSignal/+Battery/Ground pins, and DO NOT connect to the fourth (+Battery) pin. In the little drawing from Matt Reiland, use the three pins to the right. I've done this with our kit, and it works just fine.
The EduRobotics RC will provide a standard PWM signal, which can be used to drive the servos to a desired angular position. After that, it's the programmers problem!
