multiple channel servo controller

Postby liqivila » Mon Apr 15, 2013 5:51 am

What's the difference between using a multiple channel servo controller and just using a microcontroller? I'm a beginner and I'm trying to design/build a robot that has 9 fingers and is able to press different combinations of 9 keys. For it I would need 9 servos but I'm not sure whether I could just get a servo controller and program the servos directly from it, or would I need to get a separate microcontroller too?

It depends on whether your device is designed to be near a desktop or laptop computer, or if it is meant to be portable. Phidgets' servo controllers are sent commands via USB, so you can run the program on the computer that the servo controller is connected to. If your device needs to be portable, or in a location far from an ordinary computer, then you'd need a microcontroller board or a single-board computer such as the 1073 - PhidgetSBC3 in addition to the servo controller.
