Building Instructions

Building instructions for a LEGO Mindstorms EV3 Active attachment for changing gear orientations

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 

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. 

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.

Demo programs for this motorcycle are here.

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. 

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

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.

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. 

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.
