Thanks bdeull for the detailed response. I have already designed my robot in CAD with a front wheel drive configuration, but I am second guessing myself now that I remembered the results of my first iteration, which is why I asked.
I implemented a tensioner into my track design, which should take up the tension and also like I mentioned before, it is a chain and sprocket type of tracks system.
In my first iteration, I used a two sided belt with pulleys as my tracks. The cogs were not deep at all and there was no tensioner, which could have been part of why it failed.
So with a tensioner, and chain & sprocket system, should a FWD configuration be alright? I just don't want to have to redesign the whole robot, but if its necessary, I will.
I'd be happy to share my design, go to my website http://engineeering.weebly.com
