Develop leJOS programs Step by Step
In next 10 years, Robotics will become in one of the most helpfully technology for the society. Currently, robotics field is not in a mature phase and it needs new ideas to evolve but this goal is not easy because robotics is a complex science and it has several research lineas as as Localization, Computer vision & Neural Networks for example.
This ebook is a project to spread the knowledge about leJOS project and Java
techniques to develop software for robots. This ebook is a live project and every 3-6 months, I will try to update with new ideas and techniques from the projects and the readers.
Enjoy, Learn, Contact with me to improve the eBook and share ideas.

Educational courses
If you are going to teach a robotics course in next 6 months with the platform Lego Mindstorms NXT, contact with me to help you.
If the course will be teached on Secondary school, I recommend you to use NXT-G or Java leJOS,
but if it is a University Course or a Postgraduate/Phd program, I recommend Java leJOS.
I allways say that every hour with LeJOS is a training hour of Java. Currently Java is used in
Servers, Desktop, Mobile phones and Embbeded systems.
If your pupils learn Java when they were teenagers later they will become a nice Software Engineers because
they will learn Java and others technologies as UML, JUnit, IDEs, Ant, etc.
