Third, and last video of this series on how to use ONE attachment to solve the FLL 2014 World Class missions.

In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow

In the video we improve on the robotics mechanism for pushing the different blocks out of the robot container. We continue from the previous video.

Taking/Grabbing loops is one of the most common mission types at robotics competitions like FIRST LEGO League/World Robotics Olympiad. This tutorial is about an attachment that grabs the loop. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

Sometimes you could just throw a ball from base and solve a competition. Or at least many teams think so. In this video we would explore a very simple attachment for throwing balls from base. Can you use this for other missions? - we think so. Check out the video. 

Extend the previously build attachment for the FIRST LEGO League (FLL) Nature's Fury competition so that we can move the Truck and Ambulance up and down. 

Reusable attachments are our favorite. They could be used in a number of different scenarios especially on robotics competitions like FIRST LEGO League/World Robotics Olympiad. This tutorial shows how this reusable attachment could accomplish a mission for lifting a lever. It uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

In the final video we explore how to trigger the release of the attachment with just a rubber band. The release is triggered with a gear wheel that rotates in a specific way. This saves speed, does not require additional LEGO Mindstorms motor and is precise enough for a competition. 

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.

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 episode I would like to show you a way to solve the FLL 2012 Medicine mission using an LEGO Mindstorms NXT Ultrasonic Sensor and a system of gears that converts circular motion to linear.

This tutorial shows how quick pinless attachment collects loops. Such attachments are popular at the FIRST LEGO League competition. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

Improving the construction for the World Robotics Olympiad missions. The improvement is in the position of the sensor and the size of the balls container. 

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.

In this second part we continue with the next few tasks from the FIRST LEGO League (FLL) 2013 competition. Using the same rubber band attachment we lift the house and collect a few of the humans and cargoes.

Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.

This quick pinless attachment is designed for collecting parts by pushing them. It shows the principle of putting a robot of an attachment in a very fast manner. Such attachments are popular at the FIRST LEGO League competition. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

In this tutorial we will go through a solution for three of the missions from 2012 FIRST LEGO League competition using only one attachment. By accomplishing the medicines, strength exercise and cardiovascular missions we earn 55 points. You can download the programs from the link in the Materials tab. 

One of the simplest tricks in the game - move, complete the mission and leave the attachment with the mission model. You don't have to return the attachment to the base. On some competitions there might be penalties, but it might be worth it, as you save time to complete another mission. This works especially well with large attachments.. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

Connect the attachment to the box robot and find the correct number of rotations of the middle motor that would bring the robot up and forward and would attach it to the mission model.

Remember the passive/active attachment separation that we are making at FLLCasts.com. This applies for all the attachments and in this Episode, we are looking at how to use a passive attachment.  

In this video we are solving part of the FIRST LEGO League Senior Solutions challange missions (FLL 2012) using LEGO Mindstorms NXT robots. I make a step by step explanation of each move I make. The goal of this video is to help you with ideas and suggestions on how one should look at the missions.

This animation demonstrates a vertical lift attachment. This is an attachment that transfer a circular motion from the motors to a linear motion and is a very powerful concept. We demonstrate it with a LEGO MINDSTORMS Robot Inventor robot build from 51515 set. This is arguably one of the most complex attachments in this course.

How great is the great attachment for lifting that we built in this course? How many times can it lift the robot without making an error? How great are your attachments and how could you test them? - the answer is simple. Just try 10 times and they should work at least 9 of them as our attachment is.

This animated video tutorial demonstrate the use of a lift attachment to accomplish loops mission. It is a lift attachment with a circular motion

There were a few problems with the 40 teeth gears that we were using. Let's list some of them

The M08. AEROBIC EXERCISE is one of the very common types of mission in FIRST LEGO League robotics competitions. I think this pattern of missions was first introduced with the growing abilities of the participating students that were constantly reaching the maximum number of points. So the competition introduced mission that require a lot of time - 20-30 seconds, are time consuming and are complex. They requires a lot of moves. This here is a video tutorial on how it could be accomplished
