Part three of the Catapult series is about loading the catapult automatically. We use a gear system with a medium complexity along with a very interesting "clutch" developed with parts entirely from the LEGO Mindstorms NXT kits. As a result, at the end of the video, the Catapult automatically loads and fires.
The telephone game played with LEGO Mindstorms EV3 robots relies on the Color Sensors and the detection of colors. Sometimes the robots won't work. They could be influenced by a number of factors like the position of the sensor and the lighting in the room. This tutorial is a demonstration on how to account for and resolve this issue.
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.
There are some fundamental rules that we advise you to follow while organizing this course with students. Let's look at them.
In this video we are solving Senior Solutions missions: Stove, Gardening, Similarity recognition, Ball game and Wood Working. We will make step-by-step of everything we do on the FLL field.
We discuss the state of "Lost" and the different ways we could escape this state. We also build the next step of our State machine programming pattern where the next state is determined by the previous state.
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.
Based on a request we are showing the robot construction with two rear motors instead of a differential. In this way, as a construction, it is closer to more students, but much more challеnging for programing.
In this episode we do a full run of the mission for collecting a single treasure before going into explanation on how we have programmed the robot.
Collect the humans and clear them from the rocket launching region. This is rather straightforward as a task, but it requires a little bit of thinking if you want to do it without manipulators.
In this tutorial, we would implement a program that finds the minimum and maximum value detected by the sensor and stores this two values in an array.
Implementing the next logic for aligning to the border when we approach the border from the right.
Motors can be placed in opposite directions... opposite .. directions. Robo-builders might have difficulties imagining it so we have build one. One of the motors facing forward, the other backward. It is interesting how this robot turns.
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 episode we will show you how to build the FiveMinuteBot. We will make a quick overview of this Mindstorm Robot.
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.
Don't limit yourself to the box and think of different ways to lift the robot.
Time to lift the robot. The first approach is by using the 40 teeth gear wheels that come with the LEGO Mindstorms EV3 and NXT robotics sets.
How should an instructor use this course when working with students and a group of students in school
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.
Where should you lift the robot? Especially if you don`t have the mission model that we are using
The final video from the course. The robot escapes the state where it is lost. This happens if it can not continue in any direction.
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.
