A neural network for Java Lego robots

A neural network for Java Lego robots
Learn to program intelligent Lego Mindstorms robots with Java
The Lego Mindstorms Robotics Invention System lets you design and program real robots that do what you want them to. By using artificial neural networks, you can build intelligent robots that can learn and show emergent behavior. This article describes the backpropagation algorithm, a basic neural network, and its implementation on a Lego Roverbot with Java.

Developers can build intelligent robots with Java, as it provides APIs for programming systems that can see, hear, speak, move, and even learn, using neural networks, which are algorithms that mimic our brain.

This article shows how to develop a robot that can learn by using the backpropagation algorithm, a basic neural network, and implementing it on a Lego Roverbot. Using both the algorithm and Java, the Roverbot?a Lego robot vehicle?can learn some basic rules for moving forward, backward, left, and right.

In this article, we use the Lego Mindstorms Robotics Invention System 2.0 for building the Lego robot; leJOS 2.1.0, a little Java operating system for downloading and running Java programs inside the Roverbot; and J2SE for compiling the Java programs under leJOS.
