choosing required components

I am trying to build a robot but I could not figure out how to build it since I am newbie.

My plan is buliding a robot that has 4 DC motors( 4WD ), 5 Servo motors (arm) , 10 sensors (IR and Ultrasonic) and magnetic sensor.

my main issue is finding a microcontroller board that can handle all these actuators & sensors.

In fact, I could not find any board that can control 4 DC motos (bi directional) and has output of 3A for each motor.
