I reworked the design again. However it seems to me that the way forward is to resolve the internals first, then I can build a box they fit inside. I can rework the chassis ad infinitum without moving forward so I need some help.


Drive motors are for a 1.5KG robot so I don't need a lot of power. Would something like 12V Pololu 75:1 be enough? I was looking for something a bit more torque but find it hard to find anything under 100g seems to be a jump from these 10-30g units to 150-250g units


Hubs to fit


Wheels very dependent on matching wheels to chassis height I want big wheel just clearing floor and roof for anyway up driving.


If it was the mentioned motors I could get away with a pretty small ESC but these 20A Turnigy are cheap and light.


Want to ensure I can save some weight for weapon motor and armour

Appreciate any feedback
