Re: Viable Stair Climbing Drive System?
Interesting idea and nice thinking outside the box.
The first issue I can see is with drive chains - as the front wheel articulates, will the distance between sprockets change? This changes how much chain needs to be between them and throws chains out of tension.
A solution is to chain your pivoting member to a sprocket attached to the actual pivot point - this way the distance between any connected sprockets does not change.
