Solution for Sloped terrain

I came here to find out wether there is a slope solution for FarmBot.
I wondered, since I met FarmBot, that it may become even more efficient, and even more providential, to use it in sloped terrain.
After all, in sloped terrains, we have much more fisical effort to farm manualy, wich makes very steep areas manualy unfarmable at all.

Searching the forum, there are 3 Topics talking about this, neither of them solving it, though:

Then I imagined a solution:

Create a piece that adjusts an angle between the vertical tracks and the base tracks. This way, the base tracks will follow the terrain slope, and the base engines will have a new vertical component to work on.
But the rest of the bot will work the same way, vertical, just running on the sloped tracks.

Hope I could describe it clearly, this tecnical english is not easy for a brazilian enthusiast!

What do you think?
