Arduino Nano Robot PCB Design

My robot will need motor drivers for locomotion and sensor interfaces for obstacle detection, follow line with two ir sensors
Let's start with a few questions to nail down the project requirements. I have 3 questions for you. We'll ask them one at a time.
Question 1:
What type of motors are you planning to use for locomotion (for example, brushed DC motors, brushless DC motors, or stepper motors), and do you have specific requirements for the motor drivers (like current/voltage ratings or features such as speed control and direction control)?
motors will be N20 DC Gear Motor 3-12V 300RPM with Cable
I couldn't find any matching parts in the library for the specified N20 DC Gear Motor 3-12V 300RPM with Cable. You can try revising your query or search manually using this URL:
Would you like to refine the search query or add another part?
Refine search query.
Explore alternate gear motors.
Suggest motor driver for N20.
