Reversity - LEGO SPIKE Prime robot with two motors in reverse directions has two motors placed in opposite directions! If we just put a block that moves them both forward, the robot spins in place. So, how do we move it forward?

To program the robot to move forward we need both motors to move in opposite directions. There are a few ways we can accomplish that:
- Adjust the slider of the turn option for the Move right/left block to either end (left or right). With these settings, the two motors move in opposite directions.
- Start each motor separately in parallel threads, with each moving in different directions.
Both methods have their advantages and disadvantages. Choose the one that suits you best! Or perhaps you can think of another way?

Level B1 - Carnival - Robotics with LEGO SPIKE Prime
This is the third level of the LEGO Robotics Curriculum for students in second, third, or fourth grades.
Carnival and Amusement Park Level. Each lesson has a theme related to carnivals and amusement parks. Students learn about physics concepts of inertia, center of mass, and centrifugal force. New ways of programming the force and distance sensors are introduced. We work with new concepts: forever loop, if/then, and if/else.

Lesson 1 - Strange car
Introduction
In this lesson, we will create and program the strange car that the carnival uses for transport!
Why would the carnival use a strange car? Would you drive such a car?
They want to be funny and interesting, of course! Many carnivals and circuses use quirky versions of normal things to promote themselves, like a weird attraction or a car! In this level, we will explore some LEGO carnival ideas and how they work!
