Looks great!!!

I have couple of questions for you:...

Does the 4 outer wheels raised?

If the wheels are raised why not going for 8WD instead of 4WD?

Why did you decide to use 4 dual-nano (have no idea what it is but i figured it is a gearbox) instead of 2 gearboxes and using chain/belt to convert the power? might save some weight over there.

I don't know much about sheet-metal drive-train but wouldn't it be wiser to bent the sheet-metal towards the robot instead outwards? My opinion is that it will be much safer, more easy to work with, and stronger. But as i said, i don't know much about sheet-metal drive-train, so i also want to hear an expert on that question...

Thank you
