By testing our first designed model with a scaled down curb, we encountered a critical problem when going through the motions of the mechanism. As seen from the videos above, once the mechanism was over the curb and the mechanism needed to be retracted, the coupler interfered with the curve and thus preventing the desired motion to be completed. This led to the necessity of redesigning the mechanism.
For our second prototype, a slider-crank mechanism was implemented where the slider was a curved slot which guided the direction of the coupler and thus allowing for the appropriate retraction of the mechanism.
