Introduction

You will find here our technical pages. These pages will give you informations to make parts of robots. You will then be able to gather these parts to make a complete robot. Some examples of small robots we made are also presented.

The difficulty of the pages is indicated near the title by a F as Fribotte :

no sign = easy, = medium, = difficult

You will easily find the new pages with the sign .

Of course, you can add your own pages by sending them to us at fribotte@free.fr or by using our forum.

We try as much as possible to translate our French pages into English, but it takes time and besides our English is not fluent at all !!! Do not hesitate to help us translate the pages or correct them !!! As we say in French, "we would be eternally grateful" ;-) !!
