Our study is about the system RICA, what means investigation robot of blind cell (Robot d’investigation de Cellule Aveugle). It’s a system that collects data of nuclear contamination from a room without any eye contact. In other words, it’s a nuclear inspection robot. It was design to record nuclear activity, and to locate the sources of radioactivity.

 

 

RICA is composed of different sub-systems. The mobile base is the « robot »in cleanly spoken. It’s the sub-system which go into the nuclearized cell and evolve in. It is linked to the command post by the umbilicus that transmits information and power to the mobile base. The command post is the Human-Machine Interface that allows an operator to control the mobile base and to see its environment. The multiplexer permits to manage information between the mobile base and the command post.
