Glider Challenge


OUR FINAL DESIGN

1. DESIGN PHASE
-The challenge was to build a glider out of balsa wood and tissue paper that could either fly the farthest distance or be airborne the longest amount of time.
-BRAINSTORMING SOLUTIONS:
~There are NO rules to brainstorming!!
~Ideas: double wings, spikes to attack other gliders, slanted wings to push air up therefore be airborne longer, tail


-SPECIFY:
~Criteria: needs to fly (either far or long time)
~Contraints: amount of material, size of glider, time to build
-DEVELOPE SOLUTIONS:

We choose the slanted upward design because we thought that with the limited supplies we could most successfully complete the task with this model.

-PROTOTYPE: Our paper prototype stayed in the air for a significant amount of time so we decided to build.

2. TEST PHASE
-DESIRABLE OUTCOMES: flew, stayed in air decent length of time
-OUTCOMES TO CHANGE: went backwards, crashed into wall
-QUESTIONS RAISED: how do we make it go forward?
-IDEAS GENERATED: we should add a weight to the front

Machine Control Capstone Project

Brainstorming Ideas: Provide at least four of your team’s brainstorming ideas for the design solution. This should include brainstorming sketches or electronic 3D models of your ideas. Each sketch should be signed, dated, and should include labels and descriptions for communication.

Decision Matrix: Evaluate the four solution ideas using a decision matrix. Determine the best solution to the problem. Final Design Solution: See Blog post pneumatic design for picture of pneumatic design

Design Modifications: At first, we were trying to make a gate system with all pneumatics, but because the whole class was trying to do that as well, it was extremely difficult to find enough parts for everyone. We discovered that we could get the same linear motion job done with motors, so we switched our whole project to this. An exception to the pneumatic requirement was made for our group because of this learning process we went through.

Final Design:

Reflection: We accomplished in making a machine that works decently. Our model went through multiple prototypes. First we tried to use pneumatics and focused most of our energies on this but there were not enough parts so we switched out the pneumatics for motors. We found that motors could do the same motion the pneumatics did just as efficiently and were easier to program. For the most part, our machine worked quite well and achieved the main objective of sorting the marbles. However, the color sensor we used was very sensitive and seemed to vary its readings from day to day. Before each use we had to test our values and adjust accordingly. Only after this could we sort our marbles. However, the design worked quite well after the adjustments. Our other dilemma was getting it below 2 minutes. The machine we designed sorted 15 marbles in approximately 2 minutes and 25 seconds. We were given an exception for this, however. This is because motors work much slower than pneumatics. Regarding our programming, we made a main program with a singular subprogram imbedded in it, as shown above. It was a challenge to program because neither of us had ever made such an intricate program before but we received help from both David Cuban and Austin VonPohle and were able to make a working program. Overall, we believe that we succeeded in making a working program with a efficient machine.

Marble sorter with numatics!!!


This is our marble with numatics. There are not enough parts so we are going to change the numatics out for motors.

Robo Pro: Subprograms and Meter Displays





Task: Create a program that encapsulates the functionality from our previous lesson within a subprogram (incrementing a variable). Create a Main program that successfully uses your subprogram.

What are the benefits of using subprograms within your team development projects? With subprograms, you can make a more complicated main program more simply than putting it all in the main program screen. This will enable you to make more complex programs without getting confused in a bunch of arrows and seperate programs.

3.1.7 Machine Control Design Part 1



-This project asks us to make a machine of our choice. We chose the project where we are asked to make a machine that drops a chocolate chip onto a cookie.


We chose this because it had the lowest level of software difficulty and we understand our strengths and weaknesses and we are not good at programming. We are however, decent at building contraptions because of what we learned during the first semester.


-Team Members: As we are taking initiative and making up the project we failed to complete in class at home, our team members solely include Brittany Hallawell and Sarah Dobi. We are working on this project completely equally and both of us are each other's MVP. :)

-Here are our two brainstorming possible solution sketches and our programing flowcharts, one is for the dropper and the other is for the conveyor belt.






Conclusion
1. What was the most difficult part of the problem? The most difficult part of the problem was the construction of our ideas because we had to use our creativity to construct a project out of nothing but commonplace household items.
2. List and describe two features that were not part of the design problem that could be added to improve your design. One device we could add would put each cookie individually into the packaging. Another innovation we could add would make the dropping device more claw-like and therefore more precise.

ROBO Pro

In this program, the little green man starts the circuit which runs 5 cycles as shown by the A>4. The +1 with the hour glass makes it so the program runs slow enough so that the human eye can watch it with comprehension.

3.1.1

5. unchecked, 0, not present
6. checked, one, present
7. reverses conditions for 5 and 6
9. 38 to 5000
11. 1718
12. 1655
14. switch red and black wires
15. electromagnet turns reed switch on
16. normally closed
18. light shining=closed photoresistor
19. the more light the more resistance in the phototransistor
20. reverse programming
21. leave alone

Conclusion:

1. It displays the concepts of normally open and normally closed because the lines touch for one side and don't for each other.

2. A computer is able to understand analog signals because it uses A/D converter.

3. The molecules move faster and so there is less resistance as something gets warmer.

Super Advertising

This commercial is amazing, swan dive! It cost about $2.6 million dollars to make and was totally worth it. It got over 18 million hits on you tube alone and my man is now required to wear it. diamonds. ;)

Each bottle of Old Spice is approximately $4.00. This means that that about 650,000 bottles need to be sold to cover the cost of the ad. I believe that between the millions of viewers from the superbowl and the millions from youtube they will more that cover this and probably make a hefty profit.

Addressing Olson's comment: According to Old Spice, it costs less 25 cents to make a stick so that would make each bottle approximately a 3.50 profit and consequently they would have to sell more like 742,000 bottles, not much more.

-How is flowcharting similar to using a map to plan a route for a trip? Flowcharting is similar to using a map in that as you go down your desired path you have to choose different paths to get to your desired destination.

-Describe a process you do everyday. Everyday process: When I am going to eat lunch I have to decide whether I have money or not, then what I want to eat. This tells me where to go (home, restaurant, friends house, stay at school....)

DO I HAVE MONEY

Content is king


-I have a passion for legend of zelda, specifically twilight princes. Best game ever.

-Many in this field blog to tell how to get through problem areas in the game. This helps everyone get acheivements and find easter eggs.

-I could see my self blogging about ceramics because I could easily post pictures of my new works and videos of myself throwing.

Tennis Ball


-The first directions for the tennis ball challenge was for everyone to pass the ball (the only requirement was to touch it).

Originally, we had all our hands cupped and one guy touched all of our hands really fast. The other team beat us so we had to come up with another idea. We had everyone put there hands vertically in a star shape and one person dropped the ball so that we all touched it. Each one of us contributed to the design, saying what immediately came to mind. This open forum was a good way to generate ideas quickly and easily improve on others thoughts.


-After the requirements were made stricter, that the ball had to literally be passed between each person, we made a ramp with our hands and the ball rolled down it.
The other team did basically the same thing, but we made ours especially steep therefore winning the challenge. :)


-I would do it over pretty much the same because we did win the challenge (yay!). I might try to practice each thing more so that we can do it faster.


-To make the game more difficult, one could make positioning requirements for where people have to be.

I.E. three people have to be lying down or you must be in a square.


Survival


-The goal of this exercise was to order a number of items by the amount of value they had to you if you were lost at sea. In this activity, I choose water as the most important thing to bring along with you. I thought that this was the obvious choice being that a human can only survive for 3 days with out water. Next I choose a fishing kit because I thought that it could get you food, but looking back I now understand that I should have choosen the canned food over it because there is no guarantee that you will catch any fish. I choose the maps of the Pacific last because we are supposed to be in the Atlantic.
-When I compared my choices to my team we had very similar choices. Water for all of us was the top choice and the rest were in a very close range to each other. One that was radically different was chocolate. My team mates put it much higher than I did. I think that I was stuck on the health aspects of the food rather than the fact that you need food to survive.
For the most part our lists were very similar and if there was a difference then we would go with whatever was ranked the highest for the majority.
-The coast guard made some interesting choices. They were quite different from what I choose. He put the water as number 3 and the mirror at number 1. I was suprised that water wasn't first, though I did understand his reasoning that you could use the mirror to signal. Furthermore, he put the mosquito netting as last. I put it slightly higher up because I thought you could burn it or use it for fishing.
-I put more weight on experiencial data. This is because I trust the experience more than simply knowledge. If someone experienced something, they would understand it better than someone who just studied it.
