Chassis evolution: Harmonizing form and function

For a project this big, you need a solid foundation to begin with. This foundation was created with our improved chassis. Our goals for the chassis included the expansion in the front for more space for the electrical components, a flexible way to position and fixate them and compatibility with the drivetrain/suspension system of Meyer-1.To meet those requirements and some more, it was clear to make a custom-built assembly that combines the structural main frame and the electronics box. A difficult part of this lightweight assembly was, to seal it enough to protect the electrical components against rain and other particles.Aluminum base frameFirst version of the chassisThe first version of the chassis had an aluminum base frame that can bear the entire load of the rover. To make sure this is the case, multiple FEM-simulation (Finite element method) of the frame were made. The chassis must withstand loads from the…
