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.
This robot is for learning at home when you have time and energy. It is like having a motorcycle on your own - you spend a lot of time working on your motorcycle, you love it, it takes care, it takes patience. This robot has 300 steps in the building instructions. We've heard a lot of parents with students telling stories how their student could build anything from LEGO on their own. This motorcycle with a cart surely would be a challenge for them. Send us pictures when they are done.
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.
Maze Runners are one of the very popular robotics competitions. But there are a lot of limits that the robots must comply with. Like the size of the robot.
This here are building instructions for a very small maze runner robot, build with LEGO Mindstorms EV3. It uses two tires that are technic and not Mindstorms simply because none of the Mindstorms tires fit the size limit.
The robot has an Ultrasonic sensor and a Gyro sensor at the top.
Kiril Mitov's most favourite attachment. To quote him "I had a really great fun building this attachment and recording the videos for it".
It's an attachment with a Rubber band and a Flywheel and a Gear Wheel and a Worm Gear. So much knowledge in just one small attachment. The goal of the attachment is to be able to have an active attachment without actually having a motor. So you can place that attachment and it will do the work for you instead of using a motor to power it.
Build with LEGO Mindstorms EV3 set.
When placing the rubber bands check out the tutorials

This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This module uses the gyro sensor to detect when it is hit, by observing the angular rate.
The building instructions are for a robot that kind of looks like the Spy Bot but it has treads instead of wheels. Like a Tank. Tank Spy Bot. Treads are always funny and you could use the robot chassis base to extend with additional attachments and tools.
Instructions for building a LEGO truck. We use a medium motor for steering and a large motor for driving one of the rear wheels.
The NXT Competition robot was the first competition robot we designed. For most of the part in 2011-2012-2013 it was working really great. Than EV3 was released
This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This module uses the rotary sensor, embedded in every motor, to detect when the player has pulled the lever.
Building instructions for a simple car using an EV3 Large motor for turning the front wheels and EV3 medium motor with differential for driving the rear wheels.
Building instructions for a Light LEGO Mindstorms EV3 Competition Robot that could be used in LEGO Robotics competitions. Compared with previous versions of this robot, this one has a Gyro Sensor.
Uylam is a robot that simulates a stormy environment for its ship. It is made using two piston-like mechanisms powered by a Large motor and offset by 90 degrees to create shaking similar to that of big waves. The ship itself is made out of a medium motor on a turntable and a gyro sensor attached to them. The purpose of this is to explore what is the best position of a ship compared to the waves, so that it sustains the least amount of shaking.
This one is also fast. It has assistant wheels, but only to keep the balance. It is built with LEGO Mindstorms EV3 sets with the use of one additional Medium Motor.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motors, how to build them and what tasks to accomplish with them.
Building instructions for LEGO EV3 catching robot. It uses a medium motor to drive system of gears, which is used for catching objects. It, also, has an ultrasonic and colour sensors for detecting the objects.
The attachment shows how to do build a pinless robot attachment with LEGO EV3 Mindstorms.
In all building instructions for LEGO robots it is important to have the motors attached to the brick in more than one place. In the following construction, there is a beam connecting the two motors which has exactly this purpose. It makes the construction much more stable. Try removing this beam for example and see what will happen. Would the robot be able to move?
Many different types of wheels could be used. Both NXT and EV3 or from other LEGO technic series.
It moves and it collects. It collects objects.
These are building instructions for a LEGO Mindstorms robot that could collect objects. It is not actually catching them and that's why we call it "Simple Catch Bot". The general case is to program it to move on the floor and collect some of the Mindstorms wheels and tires coming with the 45544, 45560 or 31313 LEGO sets.
For World Robotics Olympiad Ball Collection competitions we prepared an interesting Robot Base Chassis that could be extended with a container. The container contains the ping-pong ball. A mechanism collects them. This LEGO Mindstorms EV3 building instructions are for the chassis of the robot and were one of the versions from a series of robots.
A LEGO Mindstorms construction for taking loops. Uses the same principle as a carabiner.
This is one of the robots used in World Robotics Olympiad. It uses chains to move ping pong balls out of a container.
