Mini Golf Project


Introduction


For term three we were given the challenge of creating Toy story five, The block or Mini golf in a group. I chose Mini golf. For this project I am working with Harry Garland and Angus Boydell. We will be trying to make a track that has many obstacles but isn’t very big. Our golf course is going to have a farm theme. It will contain a windmill, a barn, a fake gravel path and a bridge. Here are my designs / plans and code. I have a good feeling about this project, I think that we are going to be a successful group for this challenge. I really hope it will work!

                     

 

Obstacles


Down below are the obstacles that will be in the course to make it harder to get to the finish. Most likely there will be a very low chance that you will get to the finish in one hit.

The Windmill


Currently we are working on our windmill which is the first obstacle on the track. It will continuously turn around as an obstacle in the course. It is powered by an EV3 Lego brick. We have stuck cardboard pieces onto the ends of the arms as flaps. This is only the start of the windmill. As you can see it works pretty well but it will not be spinning that fast in the actual course, we might just slow it down a bit.

Now we have stuck some cardboard pieces to the sides of the windmill. There was one problem, the cardboard covered where the inputs would be, so I cut some holes where the inputs were. Problem fixed. Also, we increased the speed of the windmill, because it was too slow and therefore it was a very easy obstacle to get past. I think the windmill will be an success. Hopefully.

We have now glued together some pieces of wood to make a half box surrounding the windmill. It is there so it covers up the Lego. we still have not glued the wood onto the actual board yet but I think will be done next lesson. After that is done we might make a roof for the windmill also made out of the same material. We also stuck / put a googly eye onto the front of the windmill for decoration. There are some pictures down below to explain a bit more of our progress today. We also added a googly eye at the centre of the windmill, I do not know if you can see it but it is there.

 

The Draw – bridge


The Draw – bridge is also going to be powered by the EV3 Lego brick. It will move up and down every two seconds. The pictures below show the structure of the bridge. it is not very stable at the moment.

We have also cut out some wood from our board and installed a pole to pull the draw – bridge up and down. Harry, Angus and I are discussing whether we should have a wood platform or an Lego platform for the bridge floor. I think that we should have the Lego floor because it is easier to put on and it will attach really well. We have also coded / programmed  for the draw – bridge to move up and down. But I have not had the chance to take a video of it working yet, Sorry about that. I hope we will get it done in time.


 

Harry and I had a disagreement about what base we should put on the draw – bridge. Finally we came to an agreement / solution; we put the Lego floor underneath the wood plank so it would give the top one a better support. We attached the wood on to the Lego with sticky tape because it made the bridge a lot smoother and steadier. There are pictures below the top photos that show what it looks like. The bottom left is of under the draw – bridge and the bottom right is of the top of the draw – bridge. I will try and get a video of it working soon.

From the picture above you can see that we have got two very small pieces of wood and sandpapered the edges of them. They are now stuck together and glued to the board to double the height. Your probably wondering what it is for; it is supposed to be a ramp leading up to the draw – bridge since it is too high for the golf ball to roll up smoothly.

 

The Barn


The barn is going to be a mini house with a hole straight through it so it is harder for the golf ball to get to the other side. We will start making the barn soon but first we need some wood and some nails. Harry expectedly will bring the wood to school and we already have the nails at school. I forgot to tell you earlier that the bar is not an obstacle.

Now we have actually have started working on the barn. It is unusually tall but we don’t mind, it also has some paper with a picture of the side of a barn enlarge on it. The paper is now glued onto the sides of the barn. As you can see from the photos below we put some tiny wood plans inside the barn to stop the ball from getting stuck halfway through. see pictures below.

This lesson we made the roof for the barn. it was really easy because we only had to hot glue some cut out wood bit and stick them together. Also we put two pieces of paper with a picture of some white wood on it to cover up the top.

The obstacle Purposes


The purposes of the obstacles are probably to make the course as hard as possible. For example: the bridge is supposed to lift upwards so the golf ball would either go under the bridge or over. It was designed to stay in the air for longer than on the ground so you would have to time it right otherwise the ball wouldn’t go over. There are also no walls on the bridge so if you don’t hit at the right angle it will roll off the side of the draw-bridge midway.

Real Life Draw – Bridge

The windmill was designed to make it more challenging for the golf ball to pass from one side to the other. It is also spinning pretty fast which would make it harder for people to get the ball though to the other side. Adding to the difficulty, the blades of the windmill are big and wide so it covers up more of the area of the hole under it. Also it can sometimes deflect / bounce the golf ball away from the track. Even if you do get the golf ball through, it might have been touched by one of the windmills blades which would have slowed it down enough for it to stop in its tracks under the windmill.

The decorations


There will also be dirt surrounding the track so if the golf ball gets hit onto the dirt then it will get stuck not just roll of the board. Half of the things on this list we don’t even have, but we are hoping to be able to get them.


  •  Lots of dirt
  •  Some wood strips
  •  Painted on gravel
  •  Fake small animals
  •  Some trees
  •  Grass
  •  Rocks

The order of the decorations / obstacles


Firstly in the course there is the draw – bridge, and then the barn and finally the windmill. on the outside of the track is lots of grassland and rocks and dirt. I also heard from Harry that we are going to have the corner of a house on the board. The actual path will be flat and fluid so the golf ball can roll over the trail with ease. There is one thing that I am not sure of. whether there is going to be tiny little long walls running along side the path or not. I think our project is going pretty well so far. This is our project so far.

As you can see from the photo above, the board is traced with rocks all around the track. We have stuck some of them down but we have only done about a third of the rocks we will need to glue down. I also forgot to mention that Harry brought in a hot glue gun with some hot glue sticks so that helped a lot with the rocks. Just in case you did not know, the space in the middle of the track that looks like a rectangle is actually where the barn is supposed be. I forgot to put it in the picture as we have not hot glued it down yet.

The finished product


We finally finished our project. It took along time but now that it is done I feel a sense of accomplishment. what we had to do to get it to the final stage is we got out some black paint and painted the track black. That task took us quite a bit to do. After that we cut out the fake grass with scissors which is actually really hard to do. Then we Stuck them on half with hot glue but then we ran out of it an we had to start using wood glue. Also we have stuck some real dirt down onto the middle of the track with glue sticks. don’t worry we used the glue sticks before putting down the dirt. Here are some photos and videos to explain a bit more.

I am very happy with our finished golf course. It is a creation that I personally really like because I feel a great achievement that we were able to do this. Next time I do a group project I think I could work on being more understanding of what my teammates want to do. also I would pick a group of people that I would not usually choose to be my teammate. This project has really opened my mind to things that may seem impossible very possible.

My initial goal is to…….

Create a made up creature called the Mabel that lives in the table using cardboard, motors and sensors. The Mabel is a very big parasite that lives inside tables. Here is a scan of my design.

Lego Robotics

My initial goal is to…….

make a claw machine using a EV3 Brick and some Lego bits.

 

Here are the parts, purposes and complexities of my design:

Parts: motor, axle, claw, battery

Purpose: a machine that grabs items

Complexities: the motor turns the gear as well as the axle. The axle is fixed to the claw. when the axle turns it moves the claw.

This is the first version of my Lego EV3 project:

my code.

 

Here are the parts, purposes and complexities of (the additions to) my design:

 

 

This is the second iteration/model of my Lego EV3 project:

after this I added a bit more but I didn’t have enough time to make a video. I basically added wheels using another motor and some ball bearings, also I created a holder for the brick on top of the machine.

 

 

The parts which were the most challenging were…….

The movement of the motor because for some reason my timing for how long it moved up and down was too long.

I was able to get these working by……..

making it shorter than a second.

A Recent History Of Australia’s Prime Ministers

A Recent History Of Australia’s Prime Ministers


Harry and I are working on a project together. We intend to provide information about the six most recent prime ministers. To do this we will construct a machine that will give information by a voice  speaking to the user. This will include their names and how long the prime ministers were in power for. I expect that you will learn how we construct our machine. I hope you enjoy!

 

Building The Structure (Lesson 1)


We have built a shell and created a flap at the back of the box to give access to the makey makey which will be placed inside. We added a handle to the flap to make it easier to open and close. Here are some progress pictures.

Connecting The Circuits (Lesson 2)


We have taped a black piece of paper to the front of the box. To this we stuck the names of the prime ministers and each of these will have its own foil tab (see pictures below). Harry and I stabbed holes through the cardboard for foil to come through. The foil has been connected to the makey makey using an alligator clip.

We then built the earth wire part of the circuit (the part of the makey makey that completes the electrical circuit, allowing it to work). We clipped a wire to the base of the makey makey. The user will hold the other end of the wire when operating the machine. Then when they touch the foil under a prime minister’s name, the machine will tell them what they need to know about that prime minister.

Decorating the front and back of the box (Lesson 3)


We created a billboard / sign that advertises the what the machine does. Also we have stuck some sticky tape to the board to help it stand up. At the back of the box we have attached a cord to Harry’s computer so at the presentation will be easier to set up. We will put a speaker inside the machine so you can here the voice more clearly. here are some progress pictures.

Completing the box (Lesson 4)


Today Harry and I finished the box. This included colouring in the sides which have M’s coloured in red, white and yellow to resemble the make makey that is placed inside. We also poked holes through the sides of the box so that when we place the mini speaker inside, the sound will be projected and the voice will be much louder and clearer. If you would like to see some photos of our work, look down below.

As you can see the second two M,s are a bit rushed because the design lesson was about to end but the first two M,s are more detailed because we had more time to draw them. Also, we did add on some extra stands underneath the billboard to help it stand up because it was very droopy. Unfortunately I do not have any pictures that show you the development our box.

 

Our Scratch code


This is our code on scratch for our project.

 

Reflection


overall I think that we went pretty smoothly throughout our project. I’m most happy about Harry and I actually getting our machine done. But I also think that we could have improved on our creativity. The billboard worked out very well and that was my favourite part of the project. If I had the chance to go back and do it again then I would change the design of the box to something more stable. There small problems along the way, like the billboard went floppy half way through so we had to reinforce it will some cardboard stabilizers. Next time we have a task that needs a partners I am going to choose some I wouldn’t usually work with.

Microbit

Microbit

These are screen snips of the coding I have completed over the last few design lessons (I apologise that the screen snips are a bit blurry). I have finished some of the beginner activities provided by Microbit. For example: the Magic 8 Ball, Dice, Temperature and Smiley Buttons. So far I have learnt how to program simple things using the coding blocks but I am still in the process of learning the rest. To help avoid errors in my code, I could work on following the website instructions more carefully.

So far, I have learnt:

  •  How to fix small errors in my coding
  •  How to create my own working projects
  •  Where to put the coding blocks
