Straw Rocket
Straw Rocket
IMG_8417.movWe started off this week with building a rocket made from wrapping paper around a straw and adding a tip and fins. We were able to test around to see if the number of fins affect the rocket. By building and launching the straw rocket, we are able to learn about forces, motion, and the principles of aerodynamics that affect the flight of the rocket.
We were able to test around to see if the number of fins affect the rocket. By adding more fins, it increases the surface area exposed to air resistance, which can slow the rocket down, however since this was made from paper and the fins didn't have much weight to it, it didn't really affect the rocket that much.

Stomp Rocket
We twirled paper around PVC pipe to make the rocket body. Then, we cut several pieces of paper into 4 fins, 90 degree between each fin. Next, we made a cone for top of rocket and used tape to stick it.
We went outside to test our stomp rocket with launcher, and it succeed by flying on the sky.

The Flight
We used abrasive pad to sand wing first to form a smooth surface for wings. Then, we cut paper to make horizontal and vertical stabilizers, and attached them to the flight. Next, we added rubberbands to tighten our wings and stabilizers into flight.
Furthermore, we added propellers to our flight. We connected propellers to a pin. Finally, we released our flight on the sky and pushed it to provide thrust.

Bernoulli's Principle
We conducted an experiment to get a better understanding on how a plane lifts off. One theory that explains it is bernoulli's law. In this experiment, we grabbed a piece of paper and started blowing on it. The air flowing past the top surface of the paper is moving faster than the air flowing past the bottom surface, then Bernoulli's principle implies that the pressure on the surfaces of the paper will be lower above than below. This pressure difference results in an upwards lifting force, allowing the paper to start lifting.

This is the RockSim generated schematic of our design.
RockSim Animation.mp4RockSim Animation
RockSim Animation
This was a simulated animation of our rocket design. We initially struggled with using this modeling software, as no group member had any prior experience with any software resembling RockSim. However after following some tutorials and carefully reading the documentation, we were able to make some progress. Despite this, the software was still very finnicky and foreign to us. This resulted in our rocket diverting from a purely vertical flight path, due to weight imbalances. We decided that it would be a better use of our time to progress through the other activites, and simulate our designs in other ways.
Codrone
Codrone
drone color test.mp4This is a demonstration of our drone detecting color. It would only take off if the drone was placed on a specially colored landing pad. We used this principle in our actual code, allowing a user to control and land the drone; before pressing a button on the controller to initiate the color detectors. The drone would then 'assign' the color a temperature, and report it to the computer. We do not have film of the final code, as our time to work on the drone was unexpectedly cut short.
Data bot
Data bot
This is a modified version of the databot code sent in the discord. The version sent in discord wouldn't delete the balloon.csv file, which meant every time the data was recorded it would continue to bloat the spreadsheet. The databot also formerly reset the timer in the beginning of the forever loop, instead when the code was run, causing the timer to always return the same numbers. By moving the timer reset to the beginning of the code, the databot is able to record data with an accurate timer, then reset the recorded data the next time it's run.

Final Product
Final Product
This is the final product of the rocket we designed after making several modifications from the test design. We decided to simplify everything which allowed for the rocket to be lighter. The parachute is inside the tube while connected to the tip which has the databot.

The Flight
The rocket launch was successful, where according to the databot, went up 67 meters into the air.

End Result
This was how the rocket looked like when it crashed. The tip did come out, however the parachute did not eject out of the rocket. If we were to do this again, we would try to make the parachute smaller so that it wouldn't get stuck. Another solution would be to construct some kind of timed mechanism to eject the parachute.
