Well as I said I finally found the platform I wanted for my robot. Below is a video on how it works. Forward, back, right and left are not a problem, just 2 motors on and H-Bridge, the BIG problem is to figure out how to get setup the tracks when they need to flip. These flip with 2 other motors that allows them to elevate the robot and climb stairs which is a feature I need. Any suggestions would be great.
