Which corners do you mean? You mean the 90 degree folds in the armour at the back?

Yep, they are very vulnerable to horizontal spinners.

In Solidworks you can assign materials to different bodies so you don't have to do your calculations manually.

If you right click on a body, materials, edit material, then choose one from the list.

Then you can go to the Evaluate tab and then go to Mass Properties. It will break down all the body masses for you, give you the total and show you the centre of mass.

The reason I said steer away from GR02's is that their will come a point where there are no more left and suddenly your bot wont work. If something breaks you have no way of replacing it. You are best to design around a part you know is still in production and leave what remains of the GR02's to the machines that already rely on them.

Ah ok, I've always just gone into mass properties for each part and manually entered the densities but your way is much easier, I knew there must be a way!

As for the folds at the back I will have to see what radius I can bend them, not sure exactly how this hydraulic bending machine works so my plan is to start with the hardox and bend it then adjust the CAD to match whatever radius I get before making the rest of the parts to suit. I will ask if they are able to do a sort of chamfer bend with 2 45 degree bends spaced 10-20 mm apart.

Oh and on the GR02s my main plan is to use the new Ranglebox motors but if they cost an arm and a leg I will have to find an alternative, my hope would be that other people woudo switch to the new motors making some 2nd hand GR02s available. But I was just curious how mario mounted his wheels as I imagine a similar thing could be done with the Ranglebox ones.
