You can collect the car for scrap or repair it. The ELM teams decide to repair it. This requires them to place the engine in the car and it's very interesting to think about this problem.
We've detected the gap. It's time to move over it. This is difficult because we have to detect where the line is after the 0.1 meters gap on the line following field.
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 would be making mistakes, showing them and taking up the challenges right in front of your eyes. The first construction would not be perfect but we would eventually arive at it.
One attachment to rule them all...We have seen it and it works -> solving most of the competition models with only one attachment. In this video tutorial without programming we would walk you through the principles and methods of using a single attachment for most of the FIRST LEGO League competition models. One can learn alot from using as few parts as possible to solve as many missions as possible.
In this tutorial of the series we would get into more details on how the flywheel works, what's its purpose and how the whole attachment is triggered with the first rubber band.
In this tutorial we demonstrate how a Drop Mission could be accomplished with a Drop Attachment. The robot attachment could be adapted to other drop missions in FIRST LEGO League/World Robotics Olympiad and other robotics competitions. The principle is the same. The tutorial uses Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
"The devil is in the details". We are improving the Rubber band attachment with a Flywheel by introducing a few small, but important modifications that make the whole robot attachment more stable and reliable. With the conclusion of the series this attachment could be used as a basis for some very interesting STEM demonstrations on energy accumulation and conservation.
The next step of lifting a robot to a mission model is to try to use a rack.
Next important state is Turn Right with our robot. This happens when we detect a line on the right.
This second part continues with importing two previously developed in Episode 53 blocks into our program. With them we can for align to lines. We program the robot to align to the cross line and start following it.
Many teams have followed the same idea as the ELM team. To build a LEGO Mindstorms attachment for the robot and to lift the truck very lightly. In this way they could more the truck and place it in the special region. See what the ELM idea was.
Raw footage of the mission. Might upload a more polished version soon
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.
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M09. STRENGTH EXERCISE. I could think for a couple of missions in previous years that require lifting a heavy object. Let's see how this mission could be accomplished.
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.
Raw footage of how to accomplish the mission. A more polished version might be uploaded soon.
Build a rack and try to lift the robot with this rack.
Every time we start the robot we want to start from the same place, not only in terms of where we are on the field but also in terms of how are the motors rotate. The motors have an internal sensor for detecting the rotation. Because of this they know how rotated they are. It is a very good practice to always reset the motors before we start a competition run especially at FIRST LEGO League or World Robot Olympiad competitions
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.
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.
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.
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.
Raw footage of how to accomplish the mission. A more polished version might be uploaded soon.
Raw footage of how the mission in completed. We might upload a more polished version soon
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.
