Today my group and I met at my home garage from 12-5pm to work on rapid prototyping our concept design for the purpose of evaluating the feasibility. Using the sketch of the design, we imitated the linkage with popsicle sticks, fasteners for the pivots, closet bearings used as sliders to replicate the rail bogies, and lastly, a wire used to replicate an uneven rail. I set up the workstation in my home garage and prepped the tools we would need. Tools: Drill press, drill bits, thin circular file, table disk sander, and wire clippers. We then began construction, as can be seen, the progress in the figures below.

Below are links to download and/or view the videos of our concept design in action as in Figure 4.

Video 2: Demonstrating half scale suspension of pod car while traversing inclined rail
We have confirmed the passive suspension for leveling the pod-car while transversing inclines will work and confirmed our concern that there will be swinging needed to be dampened. Further prototyping will be planned.
