In Project Collisions, I am creating a system to deliver fast but healthy food by drones. The drone will release the package from a height up to 10 meters and my job as an engineer is to develop a solution so that the package is protected in its fall.

For Drop 0, a package with the dimensions of 12 meters, 14 meter, and 16 meters was dropped from a height of 5 meters. Below is a photograph of the package:

This is a picture of our package.

The package will hold some hot food, a burger, some juice or drink, some fruits and maybe some little snack such as chips. Inside, items are organized like this:

This is a quick sketch of the inside of our package.

The purpose of Drop 0 is to get baseline data about our package. The group developed a testing procedure so that we can be consistent on how data is collected throughout the design cycle.

During the drops, I noticed that the speed of the package dropping is very fast so it means that if we want to add a parachute it needs to be strong but not too heavy for our package.  Also, a wonder that I have watching was how can we make sure that our package lands softly and slowly with a parachute. The following data was collected:

This is our data table which records the force that was applied when dropping the package.

The average time it took for our package to fall the 5 meters was____________________<amount of time in seconds>. Using LoggerPro, we plotted out the fall of the package.

This is a screenshot of the data that’s collected from Logger Pro.

This is the whole video of our drop.

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was okay on how accurate we drop the package we missed on the plate for once out if three times of drop.  As a project metric for accuracy, we want our project to land right on the force plate in order to make accurate data.

The average force on impact was around 110 to 150. As a project metric, our group has decided to make sure the landing is soft and not out of the place too much, more than 2 meters.

Summary: Project Metrics

Our team has decided that the three most important criteria to design towards are the landing to be soft and safe, the food needs to be still hot and not soft and spilling out, and also being accurate when landing.  Below, each metric is described and the goals were determined by data from Drop 0.

• Soft landing, land with a force of 30 to 50newtons.
• Accurate landing, we need it to land on the force plate.
• Food is separated, not soggy, not combined.

Our group is now building the first prototype. I hope that it helps us see and learn more about the mistake that we have and improve to make it better and better.

This is Elizabeth’s floor plan

This is what our final design look like in tinkerCAD now.

● As a collaborator, I felt that I can help my teammates and share my ideas with them. Also as a team, I think that we collaborate well because when we needed some time to catch up we don’t just interrupt them we find a time that we can all be with each other and send many times of something that our teammates need being very patient.

● I am happy with the final design because It includes all our ideas and thinkings in our group, didn’t put in one person thinking because think that which is the best so we need to do it like that.

● One thing that I noticed our group did well when working together was being very nice and patient with our teammates, helping them when they needed the help.

● One challenge that we had when working together was catching up because in different reasons we are not able to work together at first but after we are we help each other catch up and explain what we need to.

My design is repeatable by another person because I have a procedure and I planned for the whole investigation. I realized that the data table is a little messed I would like to maybe change the order on the data table. It might have been an issue in my data collection because Sometimes the titles make it hard to see.  An improvement that I would make if doing this investigation again is just careful with the eggs and try not to break it so that we can have more opportunities for investigations. Additional information that I would like to collect to have me understand more about this phenomenon is Models & Data, clear.

What? So What?

I think a problem that we’re facing today is not enough fresh, clean water and people are also not always as aware of the use of it. And this address to my narrative because in my story there are wars because of the control over fresh, clean water and people are realizing the problem when it’s almost too late, we migrated from one place to another because of water, we are starting to move to places that have more water but in the main time it also means that there will be more likely to have war around because of the control. It’s like we see the leader as the best if they have control of clean fresh water. I hear and read before that there are only 3% of fresh water that we people can use on earth, the other 97% is water in the ocean, which are the salty water. Also, when I was researching I found that we are using fresh water so fast and so much that we might even run out of the water some day in the future so if we aren’t aware of this issue we might have a big problem in the future.

Now What?

I think that we should really be aware of how and when to use water, to truly understand the problem so that if everyone could do something to help then the problem might not get as worse later in the future. One thing that I can Collect data on is that how long do I take a shower in a month or a week. I can start to try and waste less water, and in the sometimes remind my family members to do the same as well. Or I can also tell my friends, family about how serious this issue is so that they can make a change too. This makes me realize I need to see the importance of fresh clean water to us and try to not waste water as much.

Before

Three most urgent problems:

1.  World hunger.
2. War.
3. Global warming.

Two questions:

1. How can we help global warming faster?
2. When can we end wars that till on now?

One, optimistic or pessimistic:

1. Pessimist ( 51% Pessimist/ 49% Optimist ), I think it will get better in the future.

After

1. looking back on today, how do the topics of food, water, and communities connect? Or not?

I think that it is connecting because, as human we need food, we need water and we need communities to survive.

And these are connected because these are what we share.

Also because when the population of people grow than we will have fewer resources. More people, fewer resources.

2. I used to think… and now I think.

I used to think more like a pessimistic but now I think I’m more on the optimistic side.

3. How would I sum up today’s experience? What makes me say that?

I think that I had a very good experience, and it really helps me think deeper, from what I used to think to now I think.

Collaboration, because I feel like I can work with most of the people but still I hope to improve other areas.

I think I really want to be good on 1st self manager , 2nd Communication, because if I don’t communicate well with others than i won’t have any friends, and in the future if i need to work with others than i need to communicate with them.
