Is this my favourite thing? Yes, it is. The use of levers, especially in this robot is just great. These levers make the magic of keeping the fork horizontal even when the fork is moving up an down. Try it. Start the robot. See it. It's ... magic.

Levers
First - where are the levers. See the picture below. The four white beams that the robot has, are working as levers.
All the beams are the same length. Because of this, the distance between the top of the frame on the left and the top of the frame on the right is kept the same as the distance between the bottom of the frame on the left and on the right.
As a result, both frames stay horizontal to each other. Very simple but a powerful concept of mechanical engineering.
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons
A robot a "day" keeps the questions awake. Version 1
"How to use the LEGO robots to facilitate the learning of robotics by my student at home" or simply put - "what to build now?"
After enrolling in this course we will send you a few (1-2-3) emails each month with a title "A robot a 'day'". Each email contains a robot building instructions and/or video tutorials and/or tasks that should be accomplished. After a task is accomplished we might sometimes ask for a video or picture.
This process gives a structure of the learning process where you can learn from the content. The student participates in a course, but from home and on the schedule that you decide.

MotoCar Bot. Work with gears and levers. Two magic tricks at once. Robot 5
"How do you build a forklift using only gear wheels and levers without a rake"... Ok, we would admit that is a difficult question. It even sounds difficult. So let's start with something easy. A LEGO Mindstorms EV3 robot. It lifts objects in the air. It uses two gear wheels that work together and then move in different directions and are placed perpendicular to each other... This sentence kind of got difficult again... Let me try again.
Follow the building instructions with these 70+ steps and you will have a very nice robot and you will learn a simple trick of how to use gears and change the directions in which they rotate.
