This is an edited pics in which I duplicated some wheels and stretched the "body" to see how this thing could come out.
Thinking about the suspension.
Each subchassis wll have the usual 4 links suspension set-up. The pivoting movement AND the 4 links suspension should make the rover copy better the terrain.
This in theory;-) If not I'll screw the subchassis to the mainframe.
|After some thinking I started to find a geometry for the subchassis. This is the result in a completely temporary form. The red dot is the pivoting point.|
|It seems articulation is enough.|
|Starting to seriously build. This is the subchassis.|
|With axles monted|
|8 mm solid bars lower links.|
