Lego Mindstorms ecosystem

Using any product from Lego Mindstorms ecosystem, the student could learn the Java programming language and Robotics in an easy way. Now, it is possible to install a complete Linux distro in the third generation of Lego Mindstorms and others companies like Mindsensors & Dexter Industries has released products which interact with Sensors & Actuators from Lego Mindstorms ecosystem and that boards can use the Power of the popular board Raspberry Pi 3.
