Week1 Activities
My Task Draw 10 different greens in 3D software

Doing

Design1:Pendulum

- This design involves the player hitting the ball into the head of a dragon that it opening and closing.

- If the ball is hit through the mouth then it will come out through a hole at the end that will propel the ball to the final hole.

- The Dragons head will be intended to look like Duncan the Dragon, the HCC mascot

Next Tasks

- Incorporate ideas into final design

- Create a final design

- Gather Materials

Week2 Activities
My Task#1

-Implementing Multiple Holes, Spinning Plate, and Dragon Head designs into the real world.

Multiple Holes

Week3 Activities
My Task#1

Refining Golf Green Design

-Size of Green

- The head will be 1ft tall, 1.5ft in width, and 2ft in length.

- Top of the head can be cut out and bent around to create the 3D shape to it.

- Accents such as teeth, ears, and eyes can be cut out and glued on.

- The bottom of the mouth can flat, and the detail can be drawn and painted on.

- The mechanism we will create will be very similar to the spinning reel(video of spinning reel:https://www.youtube.com/watch?v=N5PA-Q854Bw) on a fishing rod.

- A windshield wiper motor can be attached to the spinning reel to wind it back

- We will attach the string that will be wound up to the top of the dragon's jaw, this will allow for the jaw to lift up, then when it unwinds the jaw will lower down because of the weight of the jaw

- Inside the head there will be holes that will lead to clear PVC pipes coming out the back.

-Tubes

- There will be 3 tubes coming out the back of the dragons head, with one of the tubes leading directly to the hole.

- The tubes will be made out of clear PVC piping.

My Task#2

-Develop a Testing Protocol for Determining Par

- Ten college aged students at HCC will be selected at random, five boys and five girls.

- They will be asked to play our finished course once each, and the number of stokes it took them to finish the course will be recorded

- The average of all their scores will be taken, and the number will be rounded up if the number is .5 or above, or rounded down if the number is .49 or below.

- Whatever number we get will be the par for our course

Next Steps - Figure out the lip for the front of the ramp and how to make the balls ascent on it smoother

- Get the windshield wiper motor and program it so it will work with the dragon head

- Document all steps on the team page

Week4 Activities
My Task#1

Reined Testing Protocol

- 60 Golfers will be picked, 30 of which golf at least once a month and the other 30 play very rarely or not at all.

- They will be asked to play our finished course once each, and the number of stokes it took them to finish the course will be recorded

- The average of all their scores will be taken, and the number will be rounded up if the number is .5 or above, or rounded down if the number is .49 or below.

My Task#2

Solving the Lip Problem

- The lip refers to the beginning of the ramp

- The problem is that there must be a smooth get-up onto the ramp so the golf ball will not hit the lip and bounce off

- The solution would be for the bottom of the ramp that will be touching the floor will be flat, this is what has been used of the other golf holes already found in the classroom, and after testing it out, this lip solution worked

My Task#3

How to transport and store the golf green

- To make the golf green portable, it will be made so it can be disassembled into multiple pieces.

- The borders around the course can be broken up so at least one person could handle a single border

- The golf green surface could be rolled up for easy transportation

- The mechanisms on top of the green would all be in one piece, but each mechanism would be able to be pulled off and transported.

- This can allow for the whole thing to be able to fit into a mini-van without much hassle, and with three team members moving the stuff back and forth it should not take but two or three trips to get it all loaded/unloaded

Week5 Activities
My Task

Testing

Test#1: Ceiling Tile Ramp: -A 2ft by 2ft piece of ceiling tile with a thickness of about .16in was placed at different angles of elevations. A golf ball was rolled up the different elevations and observations such as how far up the ball made it and did the ball bounce at the lip were recorded.

- Observations: When the angle of elevation of the ramp is decreased, then the ball is  less likely to have the lip affect it. Also, as the angle is decreased then the ball has a lot easier time getting up the ramp and travels with ore speed up it.

Test#2: PVC Piping - Does the golf ball travel faster and farther on carpet or on a yoga mat. - The mouth was placed 12.5in off the ground, and the length of the pipe is 26in. The reason 12.5 was chosen is because that is how far off the ground the pipes will be on my team's current design.We then did a few trials with the ball rolling on the carpet and recorded the distance traveled. Then, we placed a yoga mat that was 66in in length and 24in in width. We observed. The reason we did this was because we felt the ball traveled too quickly on carpet and needed a way too slow it down without increasing the distance from end of the pipe to the whole.

- Without Yoga Mat(On Carpet)

-With Yoga Mat

- Observations: The yoga mat slowed the ball down significantly, so a yoga mat-type surface can be used to slow down the ball wherever we feel necessary

Test#3: PVC Piping with a Ramp - The same pipe at the same height as the previous test was used. However, this time we pu a ramp with an angle of elevation of 7 degrees, with a height of 3in and a length of 24.5in 15 inches in front of the end of the tube. This test was done to see how the ramp affected the balls speed. Video of tests:https://www.youtube.com/watch?v=iWXKXkdW7d4&feature=youtu.be

- Observations: The ball having to go over the ramp made the ball go slower than it would if it was traveling over a yoga mat.

'''Test#4:Which is Better? A Golf Ball or Wiffle Ball :''' - The test that was done was both the golf ball and wiffle ball were rolled on the carpet. The golf ball was able to roll faster, and travel in a straight path, while the wiffle ball would go in a direction completely different from the clubs direction, and would skid on the carpet instead of rolling like the golf ball. The golf ball should be used in this project.

Final Observations

- In regards to the lip, as long as the angle of elevation is at a low enough angle(a max of 25 degrees), as well as the thickness of the lip not being too thick(less than one-fifth on an inch) than as long as the ball is hit at a controlled speed that their will not be a lip problem.

Next Steps

- Do more testing on lips

- Record all data onto the team page for the use of future teams.

Week6 Activities
My Task#1

Testing Optimal Time for Dragon Head to Open and Close

- 24 inches long by 3.4 inches high, an angle of elevation of 14 degrees.

Slow Putt:

Fast Putt:

Final Observations:- The lip becomes less and less of a problem as the angle of elevation is decreased, these test re-enforced what we learned during the tests my team did last week.

-On the course it would be best to use a thin piece of material and have a very small angle of elevation, ideally less than 25 degrees. Based on the current specs where the dragon head is one foot off the ground, then we would need a ramp measuring a length of five feet to get a angle of elevation at 19.7 degrees.

- We should probably rethink the height at which the platform in the dragon's is resting, or else the course will be way too long, and portability would become an issue.

- Ideally, the ramp should be no longer than 3ft, so it can fit with in the overall design which is 14ft long.

Final Thoughts

- If a much thinner piece of cardboard was used for the test, then the ball would have bounced off less.

- Also, if i would have done more than just putting a piece of tape on the cardboard to reduce the lip problem, then the lip would have been less of an issue.

- With that in mind, i feel that based on the criteria above, the 24.5 degree ramp would be the best of the bunch. We would only have to reduce the height of the platform inside the dragon head by 3 inches to meet the 3ft length, but using a 4ft length and keeping the height the same is certainly an option as well.

- As long as you have a thin piece of material to use for the ramp, create a smooth point of contact between the ramp and floor, and have an angle that is not too steep(based on testing done over the last few weeks, 25 degrees would most likely be the max), then the lip is not a problem.
