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.

Collaborations

If you like leJOS project and you like to share with leJOS community your advances, please contact with me.

In leJOS exists many task to do:

• Artificial Intelligence
• Neural Networks
• Qlearning
• Control systems
• Fuzzy logic
• Mobile services (Add new features to a NXT brick from a mobile phone)
• Graphical environment (A similar concept in relation to NXT-G)
• leJOS simulator
• Integration technologies
• ICE
• XML Support for leJOS
• Finish Junit support for leJOS
• Zigbee support for leJOS

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.
