Object aligning and holding xtures for robotic assembly 13 tasks are important in industry in order to successfully complete an 14 assembly. However, the designing of a xture is usually done manu15 ally which can be a long and tedious process including many iterations, 16 even for experienced engineers. This paper presents a method to design 17 xtures automatically for use in robotic assemblies and pick-and-place 18 tasks. To achieve this, a new automated method to design the cut-out for 19 a xture is introduced. The method uses a parameterized version of the 20 object's imprint to design the cut-out. The xtures generated using this 21 method are optimized in simulations to determine their nal parameters 22 for a speci c application. Dynamic simulations are used to evaluate each 23 iteration of the cut-out. Lastly, the method is applied to a use-case from 24 the industry to design a xture for use in a robotic assembly task. 25
