The constructions we have built so far turns like a tank. The two driving wheels are driven by different motors and depending on the direction we would like the robot to go we change the power of the two motors.

Today’s construction is similar to that of a car. The front wheels are driven by a medium motor. The car will turn to the direction in which the front wheels are headed. Both rear wheels are driven by a single motor. Will that cause any problems? Complete the next few tasks and observe the construction while turning.
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons
Level C1. "Transportation". Robotics with LEGO
This is the fifth level in the Robotics with LEGO curriculum for students in third or fourth grade.
For the first time robots with steering wheels are built in this level. Those robots use one or two drive motors. The work of the differential and its usage in vehicles is explored. Students learn in-depth the working of the light sensor to create better line-following programs. The first two-wheeled motorcycle-robot is built.

Lesson 1 - Steering chasis
Introduction
In this level we will construct a lot of different vehicles. In the next several lessons we will build cars with various types of drives.
What makes the robots that we've build so far, different from the cars?
One of the differences is that cars have four wheels. The other difference is that cars have on engine/motor while our robots have at least 2 motors. The last important difference is that cars have a steering wheel and turning wheels. Our robots are quite small to have a steering wheel constructions, but we can attach one medium motor for a steering wheel and program the robot.
In todays lesson we will focus more the construction and how it is moving than on the programming.
