Imagine a robotics kit that can take any shape you want. This is the Mindstorms EV3 kit.
In 2013, LEGO released a new version of its Mindstorms series called EV3. Once with the new kit, the Danish company inspires the engineers of tomorrow and continue what already began with the NXT kit.
Tons of Lego projects are shared by the hobbyists on the Internet. As I see after I explore hundreds of projects, you will also see why the EV3 kit is an inevitable source of inspiration to build robots. Yes, built modular robots with bricks, sensors, and the EV3 intelligent brick. It’s probably the best prototyping platform for anyone who loves to build different things using the same parts and components.
In the following, I explore fascinating robots like rovers, robot arms, drones, mobile caterpillar, and more.

The Battle Tank robot is engineered with all-terrain abilities and can detect obstacle using the well-known Lego sensors.
Gripp3r is a giant robot with antennas and a special gripper located in front of the robot designed to grasp different objects.
With a crazy attitude according to its designer, Kraz3 is a fun companion that reacts due to its IR Beacon.
Bobb3e is a remote controlled robot capable of steering and lift objects.
SaphirQu3st is a tracked robot able to find autonomously objects colored in blue.
At least one LEGO robot is prepared for Mars missions. Built with LEGO pieces, the LEGO EV3 controller, and with an Arduino microcontroller attached, this mobile caterpillar is featured with a 3D printer extruder to print buildings and machines.
Drawbot is a LEGO robot with pencils instead legs that draw when is moving.
This is a Lego robot that loves books. Bookreader is a digital book reader robot built with LEGO blocks, LEGO motors and has attached a Raspberry Pi prototyping board and a BrickPi. The robot has the task to turn the pages of the book.
Spybotics is a platform based on LEGO components and allows anyone to assemble the bot, control and program it for different missions.
HOW TO create a Line Following Robot using Mindstorms
From this tutorial you can learn how to build a line following robot using the Mindstorms EV3 kit.
ARM Lego robot prepares to smash own puzzle-solving record
This project is a bonus for Lego and Rubik’s Cube hobbyists. Cubestormer is a very fast robot built from Lego EV3 pieces and able to solve the Rubik Cube puzzle in only 5.2 seconds.
The EV3COMPOS3R project can be built with either the retail or education (plus extension) sets. The project allows you to compose and save tunes on the EV3 brick.
Robot Mk 3
The Mk 3 robot has giant tracks and is powered by EV3 motors. Each track is built from 75 pieces and can turn in place or climb over big obstacles.
EVB – Rubic’s Cube Solver
This is a LEGO machinery able to solve a Rubik cube. The LEGO bot is controlled via an EVB shield for the Beaglebone Black board. The Rubik’s cube is placed in the center of the boat and is handled by two arms: one arm rotate the cube, and another one detect the colors.
The MindCub3r is another LEGO robot designed to solve the Rubik’s Cube puzzle. It has a rotary plate and an arm that turns the cube puzzle according to the color detected by the sensor.
Two-Wheel Self-Balancing Robot
A LEGO robot with an Android smartphone attached to its chest. The smartphone power and control the self-balancing robot, while the user control the robot wireless with another smartphone.
This LEGO robot has two rotating discs to scan and draws what it scans. On one disc is the illustration and on the other disc is an arm that draws what is scanned.
DIY RC project
This rover powered by four servos is controlled by a Handuino controller. The controller has a built-in LCD display and a multitude of input options. The robot communicates wireless via an XBee module.
