Problem Statement
The goal of the project is quite simple: make the power wheel functional again.

Project Plan
For the first week, we will focus on designing replacement parts for the box on the power wheel itself and the design of a small bolt to better control the gas pedal. The following weeks are going to be the implements of these designs and see what else we can do to repair the power wheel.

Week 1 Narrative
During this week I worked on designing a new wooden box for the power wheel (wooden box used to support the arduino and the metal part used to steer the steering wheel) the current design isn't correctly aligned with the steering wheel so the only thing to do right now is to change the design of the wooden box so that it is aligned with the steering wheel. That is the only problem I have been able to find with the steering wheel so far, so I've just drawn a new design, just as simple. However, seeing how the design I have made is changed so that the metal part steering the steering wheel is moved to the left, we'll probably have to make some adjustments because of the balance of the power wheel, and also have to re-measure the way the parts moving the gas pedal move through the box. Next week I hope to create the new box, and make adjustments necessary for the gas pedal to be moved correctly , and the adjustments to the metal part steering the power wheel.

Week 2 Narrative
This week, I've worked on the design of the part used to control the gas pedal of the power wheel (to be precise the part to goes back and forth on the gas pedal to push it). The problem was clear: the design that we had (design in 3D on SolidEdge) wasn't oval at the end. We wanted it more oval, in the shape of a bullet. after trying random options of S.E. we finally managed to change the part of the design we needed to change. After seeking approval of our instructor, he noticed that the far end of the design had a small, thin, band crossing a hole of the part and suggested to get rid of it, which we did. Now the design is done and ready to be printed to see how it fits the power wheel. For next week, we plan on printing the part and make small adjustments so that the part fits perfectly the power wheel.

Week 3 Narrative
This week I worked on sketches of the part controling the gas pedal used as blueprints. I haven't been able to do the sketches of other views than the side view, so this week's objective is to finish that.

Week 4 Narrative
For this week, I've worked on the math necessary to find out how much time the motor needs to spin so that the part pushing the gas pedal can actually push that pedal , and a way to make it understandable by someone else than me , which has proven to be a challenge, and I worked on filling the CDIO report as much as possible with the data we have. here's the math I've done, note that it is the same that I've put on the CDIO report.

First : find the number of rotations per second $$ 178rotations/min = 178 rotations/60s = 2.96666667rotations/s $$

Second : find the number of rotations needed to obtain the distance of 1/2 inch

$$ 1 rotation = 1 pitch = 1/8 inch $$ $$ 4 rotation = 4 pitch = 1/2 inch $$

Third :find out by how much we need to multiply 2.96666667 to obtain 4 $$ 4/2.96666667 = 1.34831464 $$    $$ 2.96666667 $$ x $$ 1.34831464 = 4 $$

fourth : we know that we have 2.96666667 rotations every second, but we need 1.34831464 times the rotation for one second thus finding the time can be resumed to this

$$ 2.96666667 rotations $$ x $$ 1.34831464 = 4 rotations $$ $$ 1 second $$ x $$ 1.34831464 = 1.34831464 seconds $$

Now that we have done these calculations, we know that in order to have the gas pedal pushed so that the power wheel advances forward , we have to make the motor spin 1.34831464 seconds ( roughly 1.35 seconds ).
