How to Increase Line Follower Robot Speed: 100rpm Stepper vs DC Motor?

A line follower robot using a 100rpm stepper motor experiences delays during turning maneuvers, causing overall speed reduction. The robot is controlled by an 8051 microcontroller with programmed delays between general motion and turns. Suggestions to increase speed include switching to DC motors, though their suitability depends on the arena layout, especially if sharp turns are involved. Alternatives such as servo motors combined with PWM control for speed modulation were recommended. Incorporating fuzzy logic for improved control was also proposed. References to PIC microcontroller-based designs and related literature were shared for further learning, despite the original design using an 8051 controller.
