I have been designing a rover in CAD over the past week and am just about done with the suspension, but I now face a choice. As I move on to modeling the body and diff arm, i need to decide which side is the front and which is the back. I see many rovers others have built have the bogie forward, but then designs like Curiosity have the rocker forward. What influences the design choice? Does anyone have a suggestion on which to choose?
