Most robots, especially educational are buid with 2 driving wheels and one castor wheel. Cars are different. They have four wheels, two at the back and two at the front. And the car is turning with the two wheels at the front. This makes the construction much more challenging and interesting.
Building instructions for a LEGO EV3 steering car. We use two large motors, so that the rear wheels will be driven independently by a separate motor. For your convinience, you can use the EV3-G MyBlock for moving the Boomer.
Building instructions for a LEGO Truck. The robot is presented as an Ammo Truck but it can be used for transporting various other objects, too. The construction has a rear drive with each of the rear wheels driven by a Large Lego Motor. The front wheels steer using a Medium Lego Motor. The Brick is placed at the front of the construction which gives the opportunity to easily attach different sensors, based on the task.

Building instructions for a steering car. The front wheels steer through a Medium LEGO EV3 motor while the rear wheels are both driven by a single Large LEGO EV3 motor.
Francesco 2 is inspired by the robot Francesco.
Building instructions for a simple car using an EV3 Large motor for turning the front wheels and EV3 medium motor with differential for driving the rear wheels. Differently, from Francesco, Francesco 2 has space where a locking mechanism is meant to be built for the differential.
