Today all four of us met in the lab room and worked on the solid models of the parts. We decided on the ball casters for the front wheels and made one on SolidWorks.

We also made the main frame of the car. There are still some minor additions we have to make in terms screw holes, but for the most part it is complete.

An L-bracket was then made that will connect the motor bracket and the end of the motor near the D shaft. We made it the same width as the motor bracket so that the screw holes will line up for both brackets.
With this all the solid models were complete so that we could assemble them all into the final car. The link to the zip file containing the assembled car and an image can be found below.
A motion study on the car showing the motion of the wheels will be added later.
We also ordered our back wheels and the ball casters from Pololu which should be in by next week. Our motors, H-bridge and IR remote came in yesterday so we will begin working on the code for the car this weekend.
In total we worked for about 2 hours today on all of these parts and assembling them.
