In this episode we build a reusable attachment for a LEGO Mindstorms EV3 robot that changes gears orientation and direction. It is one of the most useful attachments that you could use to move levers up/down and right/left. Adding the attachment on the robot takes 2-3 seconds and shows a very useful general principle of how to build reusable attachments.
Next robot construction for holding and releasing balls from this container. In this video we discuss the improvements and how to use the chains to release one ball at a time.
This is a video tutorial that demonstrates how to accomplish M06 and M07 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. We use the Chain Monster box robot which is a LEGO Education SPIKE Prime robot equipped with an active attachment with gear wheels, which engage the mission model’s gears to rotate the respective parts. The entire run takes less than 3 seconds, delivering a neat and precise performance.
In this video tutorial, we demonstrate how to accomplish M11 of the FIRST LEGO League 2023-2024 MASTERPIECE Challenge competition. We use the Chain Monster - a LEGO Education SPIKE Prime robot equipped with gears and a pinless attachment that will rotate the M11 Light Show.
How to control the arm of the push bot using the two triggers on the GamePad of the FTC Push Bot?
One of the most interesting challenges in the series of FLL Competitions. Move a block and add additional floor on top of the block without damaging the construction. In this tutorial we would focus only this mission and we would achieve two movements with only one motor which makes the attachment quite powerful.
Construct two legs for both sides of the robot. The task for this video is to attach this two legs on both sides and to build a system of gears and axles that power those legs.
The robot uses one middle motor. This middle motor with the use of a few gear systems controls for different axsels. We have attached wheels on this axles so it is very easy to extend the robot construction for additional LEGO Mindstorms active attachments
This is a 10 out of 10 tutorial, demonstrating the consistency and reliability of the active attachment for switching the engine in this mission. The power is transferred through a system of gear wheels to a lever at the end. We presume that the robot is already positioned.
Sometimes the answer that you get by calculating seems not to be right. Is it the calculation that is wrong. Probably it is not the calculation, but something is happening with the robot.
It this episode we would present you with our attachment for lifting the robot.
In this episode we continue from Episode 55 and we improve the durability and stability of the attachment for a LEGO Mindstorms EV3 robot. Many times attachments are not very stable which results in gaps between parts. The goal of the video is to give basic construction ideas.
One of the very common problems with the LEGO Mindstorms and LEGO Technic Gear wheels is then a tooth is skipped. In this video, I would like us to discuss this challenge and how do we solve it.
Time to lift the robot. The first approach is by using the 40 teeth gear wheels that come with the LEGO Mindstorms EV3 and NXT robotics sets.
How do you synchronise the two levers to move with the same speed, but in opposite directions?
