If i am designing a robot which rotational motion is limited to around 270 degrees back and forth. Load isn't very much, typically robot 1-2A. what would be the best actuator for this? What about the driver?

My plan as of now is a DC Brushed Motor driven by a H Bridge driven by PWM output of TI microcontroller. Feedback from an optical encoder goes into TI and position control loop is acheived with PID. Does this all sound reasonable?

How many poles should my motor have? Any other important specifications I would need?

Can a moderator please move this thread to the robotics forum? Thanks!
 
One option is the use of a 270°+ Servo Motor, the unit only requires a simple PWM routine to control position.
