Interesting. It looks like the front wheel steers like a motorcycle. The servo seems to be oriented so that the wheel changes angle in the vertical plane, rather than rotating on the horizontal.
Are both rear wheels driven at a constant speed, or do you need to adjust the left and right motor speeds to turn? I’m assuming you run them at the same speed and allow the low friction CD wheels to slide on the nice hard floor surface.
Cool. This would be a good application for one of the Tamiya gear sets that has a single motor and a shaft on each side. Seems a waste of the dual gearbox, but I’m guessing it is what you had around.
Though, I suppose having two separate motors and gear trains allows a bit more slip than if they were both on one fixed axle.
