At the higher vocational engineering education college of Wels an ABB IRB 1600 robot is used to train young engineers in the programming of industrial robots. The process of dismantling the tool head, attaching a new tool and finding its center point has shown to be too time consuming. Therefore, an alternative solution is needed to achieve the smoothest possible tool switch. The chosen idea is to attach five different tools on one mount, even though this part would need to be specially designed to not exceed the weight limit. To achieve the goal of an extremely lightweight structure, topology optimization of the geometry is the chosen design approach. Creation of the physical object is achieved by 3d printing it out of nylon and aluminum.
