Tread Chassis Design Question
Alright, so I am new to robotics as well as this site, but here is a question I feel I have to ask. I need to ask because it will effect a future project I want to do when I am more experienced in Robotics.
Alright, so the theory behind this question has entirely to do with ground clearance with a treaded chassis. I notice that every bot with treads has very little ground clearance, and was wondering if there wasn't another way to do the chassis so you could increase the clearance and what kind of effect it would have on terrain options.
So, for reference I have a few pics of sketches. Please ignore my horrible drawing ability, as well as the pictures, as I took them with a digital camera at my desk, instead of using my scanner.

Image #2: My Design
Basically, the black lines are obviously the wheels and tread, and red is the chassis/frame for the bot. You can see in the second how it has raised the clearance by quite a bit. In the picture I used solid frames extending down to the lower wheels, but as I sit here, I am already thinking of how you could implement a shock absorption system to further enable rough terrain durability.
Basically, I just wanted to get some feedback to see if my idea is crazy, or if I am.
Edit: Thinking along another thought path (which I am prone to do) I came up with the idea of 4 treads on a bot (which I am sure isn't a new one) and was curious as to if there is a reason for not doing it, or does it just present to many problems? Image #3 is what I came up with.
