Where should you lift the robot? Especially if you don`t have the mission model that we are using

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 robot base to use in the course. You can use the robot base provided by us or you can build one yourself. 

Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms EV3 Competition robot without having the whole robot ready yet. We are continuing from part 2 where we finished the 'front' of the robot and now we will extend it so that we could also attach the rear part. 

Note for the teacher on how to organize the class to use different robot base constructions to accomplish the mission for lifting.

With this video tutorial we start the course for LEGO MINDSTORMS Robot Inventor and how to successfully program the robot for FIRST LEGO League robotics competition. It is good to have SPIKE Prime or EV3 for the competition. But if you happen to have Robot Inventor, don't be discourage. It is still possible to participate and accomplish a lot with the set.

Many times we just upload blocks and leave it up to you to use it. In this tutorial, I would like to show you how to use the implemented blocks. How to import them into the EV3-G software. How to see them in the palette. How to drag and drop them to build a working program. 

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.

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.

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. 

This is not the standard video lesson. We have always wanted to just destroy the field and see how easy it would be. We would prepare a detailed lesson in the next few months, but this was one of the first tries on completely destroying the FIRST LEGO League Seniour Solutions field.

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.

How to organize the different robots and group of students when working on lifting the robot.

In this video tutorial we would discuss the M13. OBSERVATORY mission from the FIRST LEGO League robotics competition 2018-2019 Into Orbit. This is an easy mission. You can accomplish it by pushing the level with the robot. The challenge is that there is not enough space to move with the robot around the attachment. Let's discuss how we could achieve it. 

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.

In this video tutorial we would look at the mission run for M06. SPACE STATION MODULES. The missions is to precisely push a mission model into an opening. In almost any FIRST LEGO League competition there are such missions. The tutorial contains only the mission run on the field. We accomplish a single mission. 

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.

Using the rack depends on the experience of the team. Based on this a different number of gear wheels and racks would be used.

Before moving forward here is the simple task of building the mechanism and extending the legs. Extend the legs to fifteen LEGO units. 

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.

It this episode we would present you with our attachment for lifting the robot. 

"Array initialization" is the first step in every program that involves Arrays. This applies to most programming languages and for EV3-G it is a must. 

In this tutorial, we would show you how to initialize the array and how to extract this logic in a new block

Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.

How to align the wheels and how much should you push for this solution?
