Strange Bot - LEGO Robot with two motors in reverse direction
This LEGO Mindstorms robot is strange. Can you guess what is strange about it?... The motors are placed in a reverse direction. One of the motors is facing "forward" while the other one is facing "backwards". This means that if you make the robot move forward with a Tank Block in the EV3-G software it will just rotate. To make the robot move forward, you will have to make one of the motors rotate forward and the other one - rotate backwards.
The goal of this robot is to teach students that motors could be placed in many different ways. It is not always the case that the two motors face the same direction. Also, it is quite fun.

Introduction
Today we are going to construct robots which will play the telephone game. You all know how to play this game. The first player thinks of a word and then whispers it to the next one and so on. By the end of the line the word has become completely different and everybody has a lot of fun. How are we going to do that with robots? Instead of words, our robots will use colors and instead of ears – color sensors. The first robot shows a color to the next one which shows the same color, or at least tries to do so, to the next one and so on. Pay attention that robots should stand still although they are equipped with wheels.

Robotics Supreme - LEGO Mindstorms EV3 yacht robot
The name comes from the worlds most expensive yacht, History Supreme, purchased for around 5 billion US dollars form an anonymous Malaysian buyer.
Robotics Supreme is a robot made to resemble a yacht. For that purpose it is made to look very long and its front comes to one point. It uses two large motors with tyres to move. On the front it also has a color sensor, placed so the robot can follow a line. On the back it has a Gyro sensor, so that it can turn correctly.
