0 Egg Drop 0

Total achievements earned: 25

Our design was two air packs surrounding the egg held together with tape. We slowed this down sigtnificantly with a parachute. A suggested achievement for next year would be length of flight time, awarded in steps like size and weight.

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.
