stepper motors or DC motors - emm_frag - Jun 22 4:13:00 2002

Hi all,

I'm trying to build a mini robot wich must follow a path (not line
follower but something like a maze) and I don't know which method is
better to keep the wheels go in parallel.
Is it better to use stepper motors or DC motors with wheel encoders,
or a combination of stepper and encoders?

Thanks.

anonymous,

As long as you don't hit the walls or have any floor surface
irregularities, it really doesn't matter. Steppers will be
easier to manipulate because you won't need to read and interpret
encoders, but steppers don't have much power and are pretty heavy.
I wouldn't bother to use encoders with steppers, if you're going
to use encoders, just use a DC motor.

IMO,
DLC

I would use dc motors with encoders on the wheels.
