In this project, the main goal was to design a manipulator arm with 5 degrees of freedom. The first phase was to research what already existed as a robot manipulator arm and especially to look at what types of solutions were used for these arms. Once this research was completed, we moved on to the theoretical study phase of our arm "Static study - Kinematic study - RDM study", after which we moved on to the design phase, in which we looked for several solutions for the different degrees of freedom, where we made the first calculations for the dimensioning of the parts and chose the type of motorisation and force transmissions.
