Robotics Fair Catapult Project

The challenge was to create a catapult along with my friend Vicente and to properly include a pseudocode that would instruct my built to raise and lower the lever to raise and lower upon command. Throughout the entire built Vicente and I took a total of about 5 classes to completely finish the catapult and we decided to put the vex within the built itself in order to protect it from any of the objects the catapult launches. After the mechanism was complete we found out that our catapult was indeed successful and it was fully operational in terms of functioning. To help the lever not take damage after being used numerous amounts of times we added a plate with an axle connected to it. This would allow our catapult to not be damaged as easily and rapidly.

Robotics Pull-Toy Challenge

Mr. Hudson, gave us the possibility of selecting from two options, which was either to pick a survival challenge or a pull-toy challenge. After taking time to decide, the pull-toy challenge felt the most appealing to me and I decided to pursue this approach. Our pull-toy had to have to four wheels and something that would help generate force for it to move, in my case this was a windmill. If our axle's rotated this was already a positive sign for our projects as this signaled that the pull toy was moving forward. In terms of output it was simple as this was absolutely up to the student's perspective meaning we could select our approach. The process of creating my pull-toy was overall difficult as it was my first attempt ever, but with the guidance given by the rubric, I accomplished the grand majority of my criteria. All I was missing was to add a picture and simply add a picture and finalize the completion of my windmill.

Blog Post Sobre A Meso Redonda Da Julie

A Julie fez uma meso-redonda sobre a pobreza na Coreia Do Sur e o Brasil e durante o discurso dela ela explicava varias coisas sobre a maneira de vivir. Um exemplo é como as diferentes classes sociais dentro de cada país vivem de forma diferente. Por exemplo, ela mencionou como na Coréia do Sul as classes mais baixas podem viver mais de uma vida substancial do que no Brasil porque no Brasil há uma falta de infra-estrutura. A pobreza na Coréia está afetando principalmente os idosos: quase metade dos idosos vivem em pobreza relativa, que é a maior proporção entre os países da OCDE. De acordo com uma estimativa oficial, cerca de 15% dos sul-coreanos vivem abaixo da linha de pobreza. A pobreza na Coréia do Sul é definida como pobreza relativa e operacionalizada como a parcela da população que vive com menos da metade da renda média. A taxa de pobreza é em parte atribuída à desigualdade econômica do país. O Brasil está entre as nações mais altas do mundo na pobreza. A rápida urbanização e o crescimento demográfico causaram muitos problemas nas cidades em desenvolvimento. Como as cidades crescem rapidamente, os recursos não são capazes de acompanhar a população inchada. A habitação é um dos principais problemas que muitas cidades em desenvolvimento estão enfrentando hoje. Os imigrantes que não podem pagar uma habitação adequada são forçados a construir habitação temporária sem utilitários adequados. Estes assentamentos são conhecidos como favelas. Tome Rio de Janeiro por exemplo com uma população de 12,7 milhões de pessoas, o Rio de Janeiro é a segunda maior cidade do Brasil. Com uma combinação de fatores push e pull, a migração urbana para o Rio representa mais de 65% do crescimento populacional. Isto levou a uma grave escassez de habitação adequada. Estas foram algumas das principais coisas que eu aprendi durante a discussão de Julie e isso me permitiu entender como essas questões não só afetam de onde ela vem, mas a nação que eu moro atualmente.

Blog Post About Final Project

Daniel Fajardo

Science


1: What was the challenge?
    The entire point of this project was to be able to create a model car that held an egg and was being secured by a seat belt, crumple zone or a airbag. The egg had to go down this ramp with a stack of back at the very bottom in order to give the car a form of stopping. The egg could not break or else the form of security would be a failure. This was clearly an enormous issue for us.


2: How did you choose to approach the challenge?
    At the end of all of our thinking the best option for us was to use the seat belt. What we did was create the car first and make sure that it was suitable for the egg to be held in place. The seat belt was represented by the tape and we used an enormous amount of tape in order to fully secure the egg from falling out of the cart. We stacked books up and made sure to make a 45 degree angle with the ramp and then let the cart go down this ramp to check if the egg would break or not crack after. We did this a total of 3 times and the results were pretty similar each attempt.


3: How did you test and evaluate your design?
Our form of testing this project was quite simple. We looked at the rubric and checked what were the essential requirements and the instructions. We did our procedure so we stacked the text books in order to form some sort of blockade and stopping wall for the car. We tested the speed that it would take our car to fully reach the bottom of the ramp with Robbie's time watch on his phone. Our design took a little bit more time because we were trying to come up with a clever way of making sure that the egg would be safe in the car. We tested it mainly by just creating the car and doing the actual experiment itself, which turned out to be successful. We evaluated it after the experiment was already complete and were fully complete with our results. Since the design turned out to be successful I would give it a great evaluation.


4: Evaluate and draw conclusion.

After the end of all the experiment we were able to draw all of our results and I would say they were all pretty efficient. My conclusion would be that everything turned out the way we expected and I personally believe that the results that we achieved were a bit expected. The project was entertaining because we were allowed to design a car so not only did we get to apply our knowledge of momentum we were able to do it in a diverse way.
