Project Update after Presentation 2

Based on Professor Furman's comments on our design in presentation 2, our group changed the failure situations we would be addressing for this year.  In our presentation 2, we presented the addition of a third bogie and a ratchet and pawl system, which would be used during any inclines.  The purpose of the third bogie was to help carry the load as well as add further redundancy in case the other two bogies failed.  The ratchet and pawl system was a system we designed based on what we saw in rollercoasters; rollercoasters use this system to keep the cars from rolling back when they go up an incline.

Professor Furman asked that we create a fail safe system that would be able to catch the bogie. In our previous designs, we were expecting to use a fail safe in conjunction with the steering system.  Professor Furman asked us to create on completely independent of the steering system in the case that it were to have a malfunction.  With this in mind, we went back to brainstorming.
