Glider Challenge

Challenge: To create a glider plane that stays in the air and glides for a long time.

Criteria:


Constraints:
- Certain amount of blue paper
- Can't be too heavy




Test Phase




















From the test flight, I've learned that our plane nose dives too much. It doesn't have much hang time.

My goals for the glider
- Get it to hang in the air for 5 seconds or more
- Be able to soar longer without nosediving


Our glider didn't do so well. It nosedived as we predicted and it didn't have the best hang time. It was hard to change our glider since we already constructed it and took some of it apart.

I would change our design. I would add another set of wings and slant them upward instead of slanting them parallel. That way, there would be more of a change to hang in the air longer and soar.

"Egg Drop Challenge - Iteration #1"

Total # of achievements:

Achievements:

Brainstorm:

Materials:

- Cardboard box

- Newspaper

Material size:

- My materials fit inside a cardboard box

Material weight:

- Weights more than 600 g

Drop Achievements:

I hit the bullseye

Egg Resiliance:

- My egg cracked but the yolk remained intact

- My egg cracked but was still together

Actual design:

Since I didn't have enough time to brainstorm, I picked the easiest & most cheapest way. I got a box from home and lightly stuffed it with newspapers, making sure that each newspaper wasn't tightly crumpled. Unfortunately it didn't work.

The designs that were the best had mostly styrophone or popcorn and parachutes. If I could redo my design, I would put my egg wrapped in cotton balls in styrophone with a parachute on top.

Robopro Marble Sorter

Brainstorming ideas:

Decision Matrix:

Final Decision Solution:

The marble wouold travel down and get sorted on the track by either colored marble or wooden/metallic. Then each marble would get subsorded according to either color for the glass marbles or metallic/non-metallic for the wooden and metal marbles.

Design Modifications:

We got rid of the track for the marble to go on since the marbles kept falling off. And we added a wheel so the marble could be rotated into the correct bin.

Final Design:

One marble would get pushed down one at a time. If the marble was small, it would go straight down. If not, then it would roll to the right until it hits the light sensor. The small marbles would get sorted by either metallic or wooden by the magnet. The wooden marbles would roll right through into their associated bin and the metallic marbles would catch onto the magnet, waiting to get pushed by the motor. When the bigger colored marbles travel over to the light sensor, it detects its light sensitivity, releasing the gate to send the associated number with the color and put it in it's correct bin.

Reflection: We accomplished our objectives very well. When we tried making a track for the marble to roll on and then get dropped in the bin, it wasn't working because the marble kept rolling off of it before it was to get pushed inside the correct bin. Our final results were a lot better than what we came up with before. The wheel allowed each marble to fall into the correct bin without falling out. And our magnet allowed us to detect the metallic marbles apart from the wooden marble. We couldn't get the starting motor to work so

Conclusion Questions

How is flowcharting similar to using a map to plan a route for a trip?
1. Flowcharting is similar to using a map to plan a route for a trip beause both are readable, easy to use, and give step-by-step directions/instructions on what to do (i.e. a simple task or driving to Vegas).


Describe a process that you perform every day. Develope a flowchart that illustrates a process.
2. Everyday process: getting up in the morning. First you have to get up. Then you have to brush your teeth and wash your face. Then you have to shower. Then you either eat breakfast or you don't. If you do, you have to go back and brush your teeth, then go to school. If you don't then you go to schoool.

3.1.7 Machine Control Design

1. Requirements: to design a vehicle that drives in a strait line back and forth to deliver batches of parts. Must travel back and forth based on input from a potentiometer. Must include an emergency shutoff in case the vehicle travels too far in either direction.

Components: Engineering kit tools and pieces

Constraints: must travel back and forth (2 ways); must have an emergency shutoff

5. Actual Design

Conclusion Questions

1. The most difficult part of the problem was trying to set up the car and the system that moves it. We had trouble getting the car to break on the emergency stops. Instead of stopping on cue, it would keep going and eventually get off the track.

2. Our design worked great, so I don't think there's anything more or less that we would have needed.
