This lecture is related to mechanism design of mechanical systems. In order to learn the versatile knowledge about describing and analyzing the design of complex mechanisms, the properties and types of different mechanisms will be taught. Methods to define and to describe a motion task for the design process will be provided.
The students know different catalogues for analyzing mechanisms for different criteria. This catalogue contains analyzing steps for planar and spherical mechanisms. Part of this is the mathematical description of velocities, accelerations and forces for mechanical links and between different elements of the mechanism. The students are also able to check the mechanism properties in relation to its coupler curve and its curvature.

The lectures are given by Prof. Burkhard Corves, as a guest lecturer invited from RWTH Aachen University together with the corresponding instructor, Prof. Yukio Takeda.
Students are required to self-study the contents prior to the class using the supplementary material. Based on this, homework problem is given and then, evaluation is done at the final home work.
