Week 9 (Oct 19 - Oct 26)

For this week personally, In addition to finishing my part of the presentation, I finished working on the force analysis and come up with all the different forces applied to the mechanism. Subsequently, using stress analysis I was able to come up with the needed cross-sectional area for our mechanism. As a team, we are currently working on determine the correct size of the motor.

Week 8 (Oct 12 - Oct 19)

For the week of October 12 through October 19, I personally started applying the force analysis to the tilt mechanism, which can be shown below. It's a combination of what I learned from my statics and mechanical design class in order to execute the amount of force that the tilt mechanism can take.

Week 7 (10/5 - 10/12)

For this week personally, I had to familiarize myself with Solid Works and Grab Cad with the help of my partner. Solid Works is kind of similar to Creo, which I am more comfortable with, but the buttons are all in different places. My partner is able to get me up to speed, so that I can start making parts for the suspension system.

Week 6 (September 28 - October 4)

For the week of September 28 and October 4 we are still in the process of researching in order to better our design, because it is hard to find any information about a controlled active suspension anywhere.

Compared to Week 4's research, instead of looking up professional articles, I decided to just use google instead to see if I can get anything useful. Pretty much found the same thing, suspension systems for a car. Although, the figure below is a schematic of they want to model external disturbances and quantify the design objectives such as the road, quality of sensors, and availability of controlled forces. It will be interesting to see if I can somehow apply this to our design by replacing the road variable with a railing variable or anything of that matter.
