This video discusses the fact the robot requires a few more parts that are available in the LEGO Mindstorms EV3 robotics sets. We have a number of other constructions that require less parts, but for this particular robot construction we have decided to go beyond the standard sets, cheaply buy a few more parts and build a whole box robot with them.
Our Lander doesn’t have working parachutes, thrusters, or cushions, but one important feature is realistic … it’s very fragile.
Get the lander to one of its targets intact, or at least get it to base.

We calculate the number of rotatios when a gear system is involved. The driving wheel will have to do a number of rotations for the driven wheel to rotate to a desired number of degrees. In our specific case when the driven gear wheel is rotate to about 90 degrees the legs will lift the robot.
Building instructions for a competition robot following the "Box robot" principle. The robot is built with LEGO Mindstorms EV3 and could be used at FLL and WRO.
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 a competition environment like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) the color sensor is more than useful. It makes positioning on the field quite easy and precise.
Note for the teacher on how to organize the class to use different robot base constructions to accomplish the mission for lifting.
There comes a time when you need to program the robot to "follow a line, but if another sensor detects something you would like to stop, do some work, and then continue following the line". This is applicable to competition robots as it is applicable to real-life robots.
There comes the State Machine Pattern. An advanced and very powerful concept that allows you to easily implement complex robot behaviours with a simple, well-organized, extensible, bug-free program where the robot could be in 1,2, 10 or 100 states and you will still be able to manage the complexity of the world around the robot.
As an exercise try to implement the calibration of the minimum and maximum values for a single sensor.
One of the smartest things you could do in any software program is to extract logic in small reusable, simple, understandable units. In EV3-G these are called Blocks and we are going to extract the logic for finding a minimum and maximum for each of the sensors in a new block.
This is a LEGO Mindstorms EV3 competition robot used in FIRST LEGO League Season 2018-2019 Into Orbit following a Box Robot principle. The robot has passed through the following competitions in Brazil:
Local competition in scho
Regional: Northeast
National: Rio de Janeiro
International: Uruguay
The robot is an modular construction that you could easily build upon. It is not entirely "clean" as it has parts of it not optimezed as in the other box robots, but it is a nice example and a great work from the FLL team.

These are a couple of structured examples and tutorials of how the missions for FIRST LEGO League 2015 Trash Trek competition could be accomplished. We've gathered recordings and explanations from which students and teacher can learn a lot. There are missions and attachment for dropping, carabiner, loops and other interesting and challenging robotics missions from the competition.
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 is a 10 out of 10 video tutorial for the Slide mission at the FIRST LEGO League 2020 RePlay LEGO robotics competition. In the tutorial we demonstrate how to accomplish the mission 10 out of 10 times. At FLLCasts we try to build the attachments to be as consistent in their behavior as possible possible. In this way you know how the attachment along with the LEGO Education SPIKE Prime or LEGO Mindstorms robot will behave.
In this video tutorial we accomplish the Basketball mission 10 out of 10 times. We use one of the more complex attachments for the FIRST LEGO League 2020 RePlay competition. You will see an learn how to successfully and consistently complete a mission that requires the robot to put a ball into a basket and lift the basket, or lift the basket and put the ball into it.
This is a LEGO Education SPIKE Prime robot attachment for accomplishing the FIRST LEGO League 2020 Bench mission . The attachment is designed for Gazon, LEGO Education SPIKE Prime competition robot.
This Scratch (Word Blocks) program is for controlling Gazon, LEGO Education SPIKE Prime competition robot to accomplish FIRST LEGO League (FLL) 2020 RePLAY Challenge mission 11 - Treadmill. Check out the lessons where this program is use for specific demonstrations and explanations on how the program works.

Helicopters can be used to transport cargo to areas that are difficult to reach. They are used to help others, bringing important packages like food.
