Video tutorials

This video tutorial had a different idea than what we recorded. We planned for a push/pull attachment as we've shown such attachments for LEGO Education SPIKE PRIME and LEGO MINDSTORMS EV3. However, the issues with LEGO MINDSTORMS Robot Inventor set 51515 is that we could not figure out an easy way to build a push pull attachment that meets our criteria for an attachment. Because of this we made a slight modification on the idea and it is again push/pull attachment but not moving in a line but in a circle - circular movement.

In this video we discuss how do we transfer power from the motors that are "inside the robot box" to the gear wheels that are "outside the robot box". 

Second active pinless attachment for the robot construction. It is placed in the top/right corner of the robot and includes an interesting gear system for transferring the power. The attachment is suitable for complete rotations.

This is a third example for adding an active attachment. This third attachment is now connected to the wheel at the front of the robot. Again, the attachment could be easily extended. 

One more example for an active attachment with a system of gear wheels. This time the system is constructed so that the attachment could lift heavy objects. 

This is the first Active Pinless Attachment for the Box competition robot. The attachment is placed on the top of the robot and is controlled by one of the motors. 

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.

In this video we look at the way this robot uses the LEGO Mindstorms EV3 motors. How are they attached and the what the rotation of the motor is transferred to the attachments.

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

Previously we caught the Truck with two rubber bands. The next step was to lift it. For lifting we used the Medium LEGO Mindstorms EV3 motors. In this video we are extending the attachment so that we could catch also the Ambulance. In forth video we would explore how to release both vehicles after transporting them.

We will take a look at the EV3 motors and will go into details about them

We are showing the first way we could position the motors on the robot construction. This seems to be challenging for many robot builders and that's why we are going to do it in a few different ways in the next few video tutorials from the series.

The third robot has the brick and motors placed vertically. This is quite unusual and difficult, but the construction is very powerful because it saves space.

Cable management is very important on each competition. Cables could get in the way of attachments, levers, different wheels and so on. Brick accessibility is also very important. Do not forget that the brick should be charged from time to time and that you should also be able to access the buttons. 

The FIRST LEGO League competition is similar each year. With a little experience you could accomplish most of mission. The goal of this episode is to introduce you to the course, its purpose and approach.
