Drop 1 Results

Our team constructed the first design using newspaper, string and a box.  Multiple drops took place and we noticed that we kept missing because the box always glides away and so we never had the force.

In order to improve our design, we paid attention to area where it failed. The following “FAILS” happened during the drop:

  • Kept drifting away
  • Never hit force plate

Some things also went well. Big successes include

  • Making parachute that works
  • No damage on product
  • Landed safely

For our next design, we will improve upon the first prototype by maybe not using a parachute and using a crumple thingy to protect against the force without break and it will be more accurate or we can build a parachute heavier so that it doesn’t glide.

Dropping Items

In Project Collisions, I am creating a system to deliver Diarrhea Pepto Chewable Tablets. 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  11.9 x 5 x 2.5 was dropped from a height of 5 meters. Below is a photograph of the package:

The package will hold the chewable pills but we put markers and erasers to imitate the weight of the chewable. Inside, items are organized like this:

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 when our package dropped there was not a lot of force because our package was small and. was light so soft landing might not be an issue. The following data was collected:

The average time it took for our package to fall the 5 meters was about 0.9353 seconds. Using LoggerPro, we plotted out the fall of the package.

The fall was a bit slow at the start but started to accelerate at the middle part and stayed about at a constant speed after it accelerated

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group hit the target 1 out of 3 times which I don’t think is very good.  As a project metric for accuracy, we want our project to try to hit the target more often so that the package won’t be lost.

The average force on impact was 37.3 N because that was the only time we hit the force plate. As a project metric, our group has decided to maybe try to lower it to make it as soft as possible but maybe not.

Summary: Project Metrics

Our team has decided that the three most important criteria to design towards are Accuracy, Soft landing and big quantities. Below, each metric is described and the goals were determined by data from Drop 0.

  • Metric 1: Being able to hit the target more than 50 percent of the time, maybe more than 75
  • Metric 2: The package having a soft landing so that the things inside don’t break. Reducing the force by 25 percent.
  • Metric 3: We want to have more things inside so that the people using it would have more supplies to use rather than needing to keep getting it and maybe run out quickly.

 

Our group is now building the first prototype. I hope that we put like a outer shell thing to protect the package and maybe if it works a parachute but if it glides away then maybe not.

The proofing of the plan

 

As a collaborator, I felt that I kind of shared my ideas and we had some different ideas. I am happy with the final design because it had some of our ideas in it even though some were left out. One thing I noticed our group did well when working together was that we had ideas for the rooms and stuff. One challenge we had was that the codes kept expiring so some people did not really do much in the floor plan.

 

 

Growing and Shrinking Eggs

My design is repeatable by another person because other people can see the 4 different eggs in different liquid and what the membrane might look like. I realised that the numbers on the eggs could have been a problem because if we got the eggs in the wrong container we would have got the wrong results for the egg because we can put egg 3 in egg 4 and the results for egg 3 would not match. An improvement that I would make if I would be doing this investigation is doing it with less eggs because with less amount of liquid we had basically gotten the same results and using the original amount of liquid. Additional information that I would like to collect to have me understand more about this phenomenon is to see if the time the leg is in the liquid affects the result.

First Model

Final Model

These 2 models connect because they both kind of show the eggs in the liquid and what they do. When I first watch the phenomenon, I thought that with less liquid it would get less small or less large. Key evidence indicated that I would not get less small or less large if we put in less liquid. Now, I believe that the egg is getting water inside and losing the matter in the corn syrup.

The egg is kind of like a cell because the nucleus is like the yolk the shell is the cell membrane and the egg white is the cytoplasm. The membrane is the one in the Final Model and it is like the one that keeps things that are too large out.

What? So What? Now What?

So What?

An issue is with water because in the video “Where We Get Our Fresh Water From” only 2.7 percent is usable and most of it is frozen. We will run out of water if we keep using it like this. Some people shower for so long while others don’t even have enough to drink. We need to think about how much water we use.

What Now?

I am going to try to spend less time brushing my teeth and showering so that I reduce the amount of water I use. I will also try to turn off the water faucet when I am not using it. People need to be more mindful of the water they use.

I forgot to save my initial draft and I was at the counsellor but I learned that I needed to make it more clear about the things. I changed the icons and colours.

FoF

This is the project. I could not take a picture so this is a PDF of it. This will show a table with pictures about Foragers,Farmers,Factories and the Future. There is an explanation at the bottom of the PDF.

Urgent Problems That We Need To Solve

  • Overpopulation
  • Global warming
  • Food Shortage

Questions I Have

  • Will global warming be solved?
  • What will happen?

Optimist or Pessimist

Pessimist

Looking back on today the topics of food, water and communities connect because they all are about our survival, and without them we won’t be able to survive.

I used to be pessimistic but now I still am pessimistic because the problems are hard to face.

Blogging I am

I feel that my strongest thing is research because I maybe research things. By June I want to become awesome in communication because I don’t talk a lot in small groups.
