When the project started, the only guideline was «Create a robot». But where to start? How to start? The first question usually answered by the designers is «What does the customer want?», but we decided to operate differently, the main question we wanted to answer was «What robot could be useful to people? What can we do to help ?». That lead us to the idea of creating a robot for handicaped people, we wanted to make a device helping to be more autonomous, a device that could be commanded by the head so that the user, crippled or not, does not have to use his lower body.
