SCRATCH OUT EVERYTHING THAT I SAID ABOVE!!!! IT’S TOTALLY THE WRONG WAY TO GO ABOUT THIS.

The key is the center of gravity of the whole object that you want to make walk down the ramp. It could be anything that you want – it doesn’t matter. It could be a football with two legs. The key to this problem is Newton’s laws of physics. And the key is the video that lew sent us to. Here’s a man that understands these laws and he tells us how it works. The relationship between the pivot point of the leg that pivots and the center of gravity of the object (including the leg that doesn’t pivot) is what’s important. I also would think that the degree of the incline is important. Obviously if it is too steep all hell will break loose. So you just go ahead and set that angle to there because they have determined it to be good with experiments. So when you use this info you can essentially just start from scratch and make any object walk down the ramp in an entertaining manner and it doesn’t matter how long the ramp is. This way you can design all sorts of toys that walk down ramps by using the basic principals.
