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.
This attachment is accomplishing three missions and partly two more missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot
Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.
This is a frame for the SUV Box Robot. Tis frame is an adapter between the robot and the attachments. You can add-in several attachments on it and mount them on the robot simultaneously with one movement.
The frame has two locks that make the attachments stick to the robot. Also the front Knobs must not be used for very powerful activities due to jumpings, unless the frame with attachments become heavy enough to prevent any jumping of the frame.
Robot attachment that shows you how a circular motion could be transferred to linear by using a gear and a rack. The final motion is for pushing and pulling things.
The attachment could be built from LEGO Mindstorms EV3 and NXT parts.
When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.
Build with LEGO Mindstorms EV3 parts.
This incredibly compact SPIKE Prime Box Robot is made for competitions like FIRST LEGO League (FLL) and World Robotics Olympiad (WRO). Whakatae (from Maori's word "whakataetae", which means "competitive") is long 17 LEGO units and is with a width of 15 LEGO units. In front of the wheels it has two color sensors which it uses to align. Whakatae also has two Large motors for moving and has two medium motors for attachments!
It's has "V2" in its name, because it's the second version of Whakatae - LEGO Education SPIKE Prime Competition Box robot. The difference between the two is that the first one can be built with only a Large Motor and a Color sensor in addition to the Base set, while this one needs an additional ball bearing. This provides this robot with a lot more stability and can be seen as a true upgrade to the first version.

Attachment used to transfer the motion from the motor from a vertical axle to a horizontal axle. Uses two gear wheels. Could be built with LEGO Mindstorms EV3 and LEGO Mindstorms NXT kits.
This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees.
It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion
Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the third attachment from the series.
For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
We took a stab at building a box robot entirely with chains. It is difficult to find these chains. They were part of the original LEGO MINDSTORMS NXT Robots, but we had an idea. Can we power the whole box robot and all the attachments with the chains. This allows us to do a nice demonstration when and how chains could be used.
To build the robot you will need about 180 of these the chain pars - 3711a. They could be found from NXT and from some technic sets.
This robots require additional parts on top of the LEGO Education SPIKE Prime and LEGO Education SPIKE Essentials. Check out the additional parts required.

Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the second attachment from the series.
Interesting and useful attachment for dropping a LEGO human at a specific location. It uses a lever and a gear wheel. When the lever is pressed the wheel rotates.
The attachment is constructed from LEGO Mindstorms EV3 sets.
If you take a look at the videos for this attachment you will see a nice idea on taking the track and the ambulance. These two vehicles from the FIRST LEGO League 2013 competition had to be collected and returned back to base.
Built from LEGO Mindstorms EV3 parts.
This is the attachment to accomplish Fll 2019 M06 mission with the Whakatae. You can see how to attach the attachment to the robot in this tutorial to do.
This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 3rd mission of the FLL Cargo Connect competition.
This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 5th mission of the FLL Cargo Connect competition.
