"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.
