With tutorials, courses and building instructions with gears you could learn how to use Gear Wheels, Warm Gears and Racks. Everything spins. With a few gear wheels you could make it spin faster or harder. Check out the examples of different constructions, robots and attachments that make use of gear wheels.
Given the large number of gear wheels and axles in each EV3 and NXT sets there are many possibilities for building gear mechanisms. We are developing something like a gear box that has different axles that could all turn in different directions.
We are describing the Warm gear in this video. This worm gear does most of the magic of controlling how the different gear wheels move on the different axles.
In this third video we show some of the tricks in building this Multi-axles mechanism. Things you could learn from an use in your next constructions.
In this video tutorial we accomplish the basketball mission from the FIRST LEGO League 2020 reply competition. We use the LEGO Education SPIKE Prime competition robot called Gazon. You will learn the principles of accomplishing a mission of two parts - put the ball in the basket and lift the basket.
In this video tutorial we accomplish the Basketball mission 10 out of 10 times. We use one of the more complex attachments for the FIRST LEGO League 2020 RePlay competition. You will see an learn how to successfully and consistently complete a mission that requires the robot to put a ball into a basket and lift the basket, or lift the basket and put the ball into it.
