drivebases designed to prevent tipping

[thefro526]

816 is using an 8WD with 6" wheels on approximately 10" wheelbases with the center 4 wheels dropped 3/16" in a long base configuration.

After doing a bit of 3D work with the design and then seeing it as a rolling chassis, I am fully confident in it's ability to climb the bump should we be able to keep our center of gravity low enough. None of the other mentors on my team felt that articulation in the drive train was necessary for navigating the bump and if anything it would add unnecessary weight to the robot. My personal opinion is that Articulation is not needed for most drive trains this year.

Should you want to go in the direction of an articulated drive I would see if you could get away with only having one pair of your 6 wheels articulate, either the forward or the aft. If you're truly worried about tipping, there are probably some better options for your design than building a complicated drive train.
