In this episode we look at the way this robot is balanced. A well-balanced robot could handle heavier attachments without losing track of its position on the robotics competition field.
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.

Инструкции за построяването на състезателен робот на принципа на “Box” робота. Този робот е построен с ЛЕГО Mindstorms EV3 и може да се използва на състезания като FLL и 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 this Episode, we stop at the pinless attachments for the Box Robot 2 and especially for the constructing a frame. This frame is then used for further extending the robot with attachments.
In this Episode, we create the next attachment for the box robot two. It is again a pinless attachment, attached to the frame that transfers the motion to a vertical axle.
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.
The attachment builds on previous episodes this time using two LEGO rubber bands. When a lever is released the rubber band exerts pressure on it and moves it in a circular motion. As an example we are solving the 2012 FIRST LEGO League, Senior Solutions, stove mission (which was quite interesting as a mission)
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.
These are instructions on how to build the:

Lifting a loop is one of the most common missions in different robotics competitions. In this video we demonstrate how we could do "Vertical lift". It is suitable for precise lifting especially when the mission model requires you to lift straight up. The robot attachment could be adapted to other missions at FIRST LEGO League/World Robotics Olympiad and other robotics competitions that require push/pull. The principle is the same. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
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.
Unloading cargo is an important part of the journey. Planes are often just one of multiple forms of transportation used to deliver cargo containers to their destination.
These are instructions on how to build the:

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.
An attachment designed for Heavy lifting. It's build with LEGO MINDSTORMS Robot Inventor 51515 and it has a gear wheels mechanism that allows you to increase the torque and lift really heavy things. Build the attachment and check out the tutorial. This will teach you one more principle that you could use for FIRST LEGO League competitions.
