Servo VS. Stepper motor

Hello, I'm new to the RPi B+, and im sure this isnt the best way to break the ice, just wanted to get some feedback from the community on what your thoughts were. Pro's and Con's would be awesome on comments if you could/would leave them please.

 

I'm attempting to use one to control a robot, web based(python), but need to know what would be the best approach to steering this damn thing would be?!?!?!

  • Hi

    I think they cover different areas

     

    Servo are

    1. easy to use (just connect a PWM output and that's all the hardware you require)

    2. can not (easily) control speed. With servo, typically you set a new position and the servo electronics will make the DC engine turn as fast as possible to the new position

    3. can be modified for continous rotation, but you have non control on speed

     

    Stepper motors are

    1. more difficult to use (they require external hardware to drive the motors)

    2. more precise

    3. can be controlled in speed

     

    Hope this help
