Julieta V1 is your definitely choice for a Arduino-style robot. With Julieta V1 you will be able to control DC motors, stepper motors and servo motors with only one board. Not only that but you can interact with the board using the buttons available. Needing more power for servos? No problem, Julieta V1 has a DC-DC converter which can deliver up to 3A to 5V headers. Heart of Julieta V1 is an ATmega328 with Arduino UNO bootloader, so you can treat her just like a regular Arduino UNO board. To drive motors, it has a L298 h-bridge, so you have 2 channels to control up to 2A loads each. Do you need to connect a Arduino Shield on Julieta V1? It will fit perfectly, once the black screw connectors were designed to stay as flat as they can, so it won't disturb your shield while connected.

Control each channel using digital pins 5, 7 and 6, 8. Digital pins 5 and 6 will change speed of your motors via PWM, while pins 7 and 8 will change rotation (clockwise or counterclockwise).
