Week 1 Narrative
So my goal for this week was to redesign the wooden box(frame).

The first thing i did was to disassemble the frame that was already existant, so that i could see what parts could be resued and what could not. I ran into a few difficulties though while disassembling. First like half of the screws being stripped and having to use pliers to unscrew the screws. also the wood was cut is a very poor way so i am just going to have to start from sctarch so that i can actually cut the wood properly and not strip the screws.

So to start my redesign process i mande a list of requirements that the wooden box needed to meet.

-First the arduino box should be mounted on the inside of the wooden box so that it is in a more secure location

-Next the top and back of the "box" should be open so that access to the components in the frame is easy

-The second important requirement is that the frame has to be able to house whatever battery we choose to add to it

-The frame should be secured with L-brakets in the existin 4 screws on the floorboard of the box

-The walls of the fram are to be removeable from the floorboard for easy dsassembly

-The original steering mechanism will be mounted diresctly on the center of the steering wheel because it is easier to turn the steering wheel in the middle than on only one of the sides

Next week's goal consists of actually sketching out a design for the frame that will incorporate the above requirements.

Week 3 Narrative
So my goal for this week was to draw up some sketches for so possible designs for the frame.

The first design was pretty much like the design of the previous group. The only difference would have been in the neatness of the cuts and assembly. Also I don't know how we would attach the steering mechanism mount to the frame with this design.

So I made a second one. Since I am not sure how to add pics off of my phone to the mobile version of the site i will do a symbol sketch

This is kind of what the design looks like. The reason it goes up then angles the right is so that the angled part will be perpendicular to the surface of the steering wheel for easier mounting.

Week 4 Narrative
This week i actually added measurements to the sketch of the wood frame and I made a cad model of it using Solid Edge.

I did run into some difficulties while drawing up the CAD model. The main difficulty was figuring out how to create the angled face on the model because i was not sure how to angle a rectangular face. Also every time i tried to make a rectangular face on the angled side the point would end up somewhere floating above the actual model which was rather frustrating.

my original approach to making the frame was to do one side at a time. then i ran into the problem with making the angled face so i tried a new method.

i took the one side i had already built and then extended it to the width of the frame to make it a solid. Then hollowed out the inside of the frame to get he final design

The last picture is the 2-D Multi-view drawing of the frame
