Crazy Fischertechnik Rubix Cube Solver

If we found the algorithms to solve all the sides we could develope a program in which to electronically solve the cube.

RoboPro: Subprograms and Meters

The recent activity that we had wanted us to create subprograms, specifically one that increases the value of a variable.



The benefits of these subprograms is that it provides more space to complete our main code, and create simple smaller functions where we can use a variable to define rather than recreate the entire code.

The Red Barron

Design Notes

1. The challenge of this project is to create a simple glider out of balsa wood, tissue paper, and glue. The goal of this project is to have the most distance and hang time compared to the other gliders.

2. Air resistance is the key factor to creating the best glider so our first major ideas were to create a rounded bottom and also have large curved wings.

3. Criteria:

• Sustained flight
• Durable enough for multiple flights
• Well enough assembled for a solid throw

Constraints:

• Materials

Test Notes

When we tested our gilder it didn't have a stable balance point so we added a front weight to the nose end to fix it.

4. The test day had more wind then anticiapated and caused problems at first. The extended nose snapped off so we hot glued it back much stronger. After the glue set we took the first test and it performed beautifully. The one thing I would change if done again would be having it be able to make a softer landing as to make many more throws after that.

Egg Drop Challenge - Iteration #1

Total # of Achievements Earned: 20
Achievements:

1. Material Weight: All of my materials weigh less than 25 grams = 7 achievements
2. Drop Accuracy: MISS = 0 achievements
3. Material Size: My materials were 4 pieces of paper and tape which fit in an cigar box = 3 achievements
4. Egg Resilience: INTACT = 6 achievements
5. Calculation Achievements: Arithmetic:

Algebra:  x =  xo + vo + 1/2a + t^2

• 4.37=0+0t+(1/2)(9.8)t^2
• t=.944s total fall time

Geometry:

• θ is important, because it effects the accuracy of the drop. Any variation in angle could change the whole design of your system

• θ= 83.47 

Calculus: Velocity in 1/2 second.

• Int [1/2(9.8),0, .5]
• = 2.25 m/s

6. Even though our system wasn't the lightest in the project Josh and I had the ultimate protection. We wanted to slow down the rate at which it would drop using air resistance and when it lands we had a shock absorbing very light weight material, which is the same thats used in the "pool noodles". If I were to alter anything of my project I would like to design something to make the drop more accurate. Possibly a rudder system.

Engineer Program Investigation (UNF)

1. UNF (University of North Florida) appeals to me because of the area and people attending. I have family at this college and would love to join them.

2. Electrical Engineering is interesting to me because I feel you can almost always figure out a way use it when creating and designing.

3. The most interesting would Aerospace Engineering but with only a very selective few areas of use it wouldnt be as valueable as something that would be used everyday.

Technology, Entertainment, Design

1. TED was established in 1984 and is a small nonprofit devoted to ideas worth spreading. Its basically a group who shares the rest of the worlds good ideas.

2. The website is very easy to navigate and the purpose is just that. To make it easy for people to spread ideas.  You can see a picture you like and click it to proceed to the video.

3. Technology, design, science, and even global issues could be considered "engineering" topics. They all have to do with ideas being innovated.

4.http://www.ted.com/talks/harvey_fineberg_are_we_ready_for_neo_evolution.html

http://www.ted.com/talks/carolyn_porco_could_a_saturn_moon_harbor_life.html

These are all good "talks" I've found that cover technology and innovation. They all cover a very large topic with a few small/simple ideas.

5. My Video - Adjustable eye glasses using water pressures

6. If I were to work with the glasses I feel training in optomotry and manufacturing to be able to develope and work with the glasses

3.1.4 Branch Functions

The power level is over 9000!!!!!!! This is a 5-step solution to the problem we faced.

Opt In Super Bowl Ad

The price of almost all Superbowl ads are about 3 million dollars for a 30-second airtime. In my opinion it is very worth the price because millions of people watch the Superbowl, some people mainly for the advertisements. Most of the time the companies make back 200% of what they put into advertisement. I liked the VW commercial because it was very humorous. Next year I would like to see some new companies advertise in during the Superbowl.

3.1.2 Flow Charting

 

1. Flow charting is like following a map because you have to follow it, step by step, to reach the final endpoint or goal.

2. Waking up

3.1.1 Inputs and Outputs

5. Unchecked, 0, not present

6. Checked, 1, present

7. It would have opposite reactions

9. 43 to 5000

11. 1521

12. 1360

14. Switching the wires into the opposite positions.

15. When the reed switch touches the electromagnet it gives out power.

16. Normally closed.

18. The light shining means the photo resister is closed.

19. More resistance = more light

20. Reverse the program.

21. Having it normal then it will be utilized .

1. Examine the wire diagram on the mini switch and describe how the diagram relates to the concepts of normally open and normally closed.
The normally closed side of the mini switch makes it so that the switch completes the circuit at all times, making it a closed circuit.  ___ _ ___
The normally open part of the switch makes it so that you must press the switch to close the circuit. __ / __

2. If computers only understand digital signals, then how is a computer able to interpret the analog signals coming from the interface?

Computers use the simulations of the analog inputs to produce digital signals to approximate their analog counterparts.

3. Why does resistance decrease as the NTC Resistor becomes warmer?
As the NTC Resistor gets warmer, the current will be increasing. To keep the same voltage, the resistance must decrease. 

Content Is King

1. Baseball is a hobby I cherish and love doing whenever I'm able.

2. If you look at any Major League baseball team they have a blog about themselves.

i.e. http://www.southsidesox.com/

3.  I aspire to be some type of engineer when I'm older and I believe if all the engineers pooled all their ideas it would make for a much better system of innovation.

Taking on the Seven Seas

Today, we were given 15 items to decide between in order to help us survive the seven seas. Little did we know we would be trapped out there forever... O_o

Nahhhh j/k, were all safe. The list of fifteen is as follows along with the ranking our team gave them:

1) WATER!!! easily the most essential to life.

2) Army rations, also very important to surviving.

3) Mirror, so i can flash a boat in the distance.

The main thing to surviving the 7 seas is how long you can stay alive for. And with these essential items, you would have the best possible chance for success.

UNITS!

l (distance) - m
t (time) - s
m (mass) - kg
a (area) - m^2
v (velocity) - m/s
p (density) - kg/m^3
g (gravity - m/s^2
F (force) - kg m/s^2
E (energy) - m kgm/s^2
P (power) - kgm^2/s^3

Tennis Ball Game

    This game was specifically designed as a team building activity. The principal of the game was to have the tennis ball touch every team member before shooting your hands in the air and yelling "engineering"!
    My team beat the other team because our design was vastly superior. Our first idea to move the ball from person to person involved a zigzag type motion where the ball touched every persons' hand only once and every other hand was either face up or face down. We then since modified the  idea to a staircase meathod, where as the ball just uses gravity to move around the circle.
    If you can view the image I incorperated that was the basic concept of how we moved the ball from person to person. The only other way I could see it being faster was to maybe have the ball touch less fingers. Gravity is the key factor to controling the speed the ball can travel.
