Good morning everyone, so I'm here because of a school project. I work on a Rommba 615 and I need to improve the side brush. So here is my question : are there ressources/way to simulate the impact of the choice of material on the efficacity of the brush ? I already own solidworks and matlab and I'm not afraid to to download another tool. All advices about the task in general is welcomed, Thank you in advance and have a great day
