Improving FLL Robot Game. Introduction to task for Lifting
We've already build a number of resources for lifting at FLLCasts.com. But at the end of this course we would have a robot that lifts itself and hangs on the mission model.

We've already build a number of resources for lifting at FLLCasts.com. But at the end of this course we would have a robot that lifts itself and hangs on the mission model.
Go to the missions model. Do the missions. You can then continue to the next mission or wait a few seconds at this FIRST LEGO League 2015 Trash Trek mission model and receive a few more points. Isn't it interesting. The ELM team has build a LEGO Mindstorms attachment for this robot. Let's see how it works.
We show the principle of solving the next FIRST LEGO League (FLL) Nature's Fury 2013 competition missions. Again, without any programs, but just the principles of using one attachment for most of the missions.
This video is part of a series where we show you how our Box Robot accomplished the M08 Elevator mission with 100% accuracy. The idea is that the robot pushes with enought force in the right spot, which makes the elevator turn over. The interesting thing is that the Dominator robot moves the lever after it pushes the elevator. This makes the move back possible, because the lever is now not in the way of the mission model.
Build a rack and try to lift the robot with this rack.
Raw footage of how the mission in completed. We might upload a more polished version soon
We call active attachments those that are powered with a motor. This one is in the the mission of lifting levers which is common at robotics competitions like FIRST LEGO League/World Robotics Olympiad. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This video is part of a series where we show you how our Box Robot accomplished the M10 Steel Construction mission 10 out of 10 times. The attachment is a basic lever and all the 'heavy lifting' is done by the x-y movement of the Dominator robot. This mission is one of the hard missions, because the construction is big and heavy and this requires precise movement of the robot.
Raw footage of how to accomplish the mission. A more polished version might be uploaded soon.
We can Turn Right. We can Turn Left. How do we decide which way to go if there are lines both to the left and to the right. Check out the video.
Next state in our state machine programming pattern is the "Turn Left" state and the corresponding behaviour.
Inertia triggered attachments does no require the use of a motor. Let the inertia do all the work. These kinds of attachments are very useful at robotics competitions like FIRST LEGO League and World Robot Olympiad. The robot moves, the attachment falls and grabs the ball. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
Let's record the values of the Gyro Sensor while the robot is moving and is trying to keep its orientation straight. This is an interesting experiment and we will have to use file access to write the values to a file.
In this video tutorial we would look at the mission run for M09. STRENGTH EXERCISE. The mission is to lift a heavy object in the air. And that could a complex mission. It requires to use gear wheel and the attachment should be quite strong. The tutorial contains only the mission run on the field. We accomplish a single mission.
This tutorial demonstrates how a robot could align to a black line. The code for the program is available in the course. Aligning to black lines is popular at robotics competitions like FIRST LEGO League as it is the primary way to know where you are on the field and to develop a program that is reproducible. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
The third part of the series the goal is to extend the robot attachment so that we could solve the second part of the FIRST LEGO League World Class mission challenge - to take the loop.
The attachment is now so advanced that we can do two tasks at once with it in order to solve the FIRST LEGO League 2014 World Class Search Engine Mission.
Third, and last video of this series on how to use ONE attachment to solve the FLL 2014 World Class missions.
This video tutorial is about understanding the "magic". In this video tutorial, we would conduct an experiment and will look at how exactly does the integral part of the PID algorithm compensate for the error that the LEGO Mindstorms EV3 robot makes.
Robotics competition is a large part of the FLL Competition. The field contains missions which give points and the main purpose is to gather maximum number of points for 2:30min. FIRST LEGO League competitions have different themes every year but the tasks have similar functionality. In this video tutorial we will give a brief of missions in Senior Solutions (the theme for 2012).
In this tutorial we will use Whakatae - LEGO Education SPIKE Prime Box robot to complete a mission run from the FIRST LEGO League 2019-2020 competition for the M08 Elevator mission. We accomplish 10 out of 10 in this mission. A similar approach is demonstrated with LEGO Mindstorms EV3 at FLL 2019: Accomplish every time. M08 Elevator. 10 out of 10 successful runs
In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow
This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the M06. SPACE STATION MODULES mission 9 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission. It moves forward and attaches the space station module with the space station.
Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms Competition robot without having the whole robot ready yet. We are continuing from part 1 where we finished part of the 'front' of the robot and we arrived at a construction that we didn`t like and would fix in this video lesson.
The final way for lifting our box robot is by using a scissors mechanism. In this Episode, we would discuss the benefits and advantages of this mechanism.
All worked as expected, up until know because the robot got lost. This happens when we turn right and the line does not continue to the right. Now the robot must somehow understand that it is "lost" and escape.
We continue from part 4 where we made a controlled experiment to transfer power from a Mindstorms motor to the rear wheels. The construction was too complex and inefficient and in this video lesson we are improving it by lowering the differential and removing all gear wheels from this LEGO Mindstorms EV3 Competition robot.
