Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the third attachment from the series.
Probably the largest multi-purpose FLL attachment at FLLCasts. These attached is doing a number of missions at once. 4 of them. You attach it to the robot and start the program. The robot moves and accomplishes a number of missions using only this attachment. At it also has a lot of parts. It is quite large and you can not build it from a single set. But that's ok because you are preparing for a competition, right?
The third version of the EV3 Easy Bot. This is a simple and easy to follow robot, that aims at showing the use of tyres on robots. The robot has a gear up ratio and no tyres, so it is quite fast and entertaining.
This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This is the simplest module for constructing and programming. At the bottom, a channel is left for the cable to pass through.
This is a simple LEGO Gear System with a ration of 1:5. When the large wheel rotates 1 time the small wheel will rotate 5 times.
Instructions for building a LEGO truck. We use a medium motor for steering and a large motor for driving one of the rear wheels.
These are building instructions for an attachment accomplishing the FIRST LEGO League 2017-2018 Slingshot mission. The based of the robot is LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro
This is the third version of the LEGO Mindstorms Grabber. This time we use a LEGO EV3 Medium motor and worm gear to make the two levers move smoothly and symmetrically.
For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
Building instructions for a LEGO Mindstorms EV3 robot where the motors are placed in an unusual manner. They are vertically placed on the sides. This robot construction base is very convenient for a quick and interesting robot on which you could build.
Building instructions for this LEGO Mindstorms EV3 robot used in the World Robotics Olympiad Junior competition
This LEGO Mindstorms robot base is small, compact and packed in a very small volume. The goal of this constructions is to be used as a base and to show yet another way to experiment with adding motors to the brick.
Gen comes from Gendema, a bulgarian late 80s rock band, popular with its song about pedalos.
The robot uses two EV3 Large motors to move, but instead of wheels it uses four-legged paddles, attached to the motors. This makes it look like a pedalo. Additionally it slides on the ground much like a real pedalo on the water.
Because of the strange mechanism of movement, the robot has a gyro sensor to help it keep a straight line.
LEGO Mindstorms EV3 Robot designed for a Folk Race competition. This robot has three Ultrasonic Sensors. Follow the building instructions and at the end, you would have a very basic robot with tank treads that you could directly use.
Building instructions for a safe mechanism. The medium motor can be used for dialing in the key lock. The brick buttons can also be used for a pin code input.
One of the large motors unlocks the latch, the other one opens up the lid of the safe.
These are building instruction for a working automatic catapult with a motor and a touch sensor.
Hrutur, from Icelandic, means Ram.
The robot is made to resemble a Ram. Its main focus are the gears, which make it go faster so that it can ram harder. It uses two Large EV3 motors to power the gear systems. At the front it has an Ultrasonic sensor for aesthetic purposes, which you can use however you like.
Building instructions for constructing a simple LEGO Model that has red, green, blue and yellow beams. This makes it perfect for operating robots through color code.
We've built a box robot chassis that could easily be extended with attachments for FIRST Technical Challenge competition.
If you ever felt that FIRST Technical Challenge is difficult and you don't know where to start from, building this Tetrix robot is the first thing that you could do. You would have 4 motors, plenty of space for attachments and good access to the phone.
The robot is built from a Tetrix Set without additional parts. It's a winning robot in just 109 steps
"You need to step on three points to be stable". This is something you could directly see after building this marvellous, 270+ steps, extremely interesting Motorcycle with a side cart. Yes, we are proud of it. The robot is suitable for using it at home. The instructions for building it contain more than 270+ steps so it is a test for endurance, concentration, passion. The same way driving a motorcycle is.
Or you could just step into the cart, drive along and enjoy the view while someone else is building the robot. Like a sibling or a parent.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motorcycles, how to build them and what tasks to accomplish with them.
