HI,

The encoder based localization is accurate. Make sure you are using the Ideal differential drive model(wheels axis rotation is in the center of the robot). Your localization accuracy depends upon the encoder resolution. Please take a look at this paper for kinematic of differential drive model. You can convert the encoder data x, y, and theta(odometry data), take a look at this code

NOTE: You can also add magnetometer to improve theta. as per my experience, angular displacement gives more errors.
