Treball desenvolupat dins el marc del programa 'European Project Semester'.

This report includes the process of designing an armadillo robot and the analysis preceding the choice of the topic. Finding the first ideas for this project required extensive analysis of different bionic related disciplines in nature. The final topic tur ned out to be basic research about making a robot with several armadillo features, such as rolling up like a ball and walking. Prior to start the designing and building process, primary research was made in order to gain necessary knowledge . The background consists of information about the features of the armadillo, leg analysis, electronic and mechanic components, 3D printing and programming. For executing the project it was important to use different steps of a designing process where we could see where f ailures would occur during building the actual robot. The final design that is chosen is a ball existing out of three segments with an opening and closing system which is controlled with one actuator. The walking mechanism of the final design exists of six legs to keep a good balance. In this report the assumption is made that the project will be continued by another project group of the EPS program of next year.
