Mini Golf Project Term 3 Farm Theme

 

This term our design project is a mini golf course and I am working with Leon Ho and Angus Boydell. The size limit for the course is 3 meters long and 1 meter wide. Our mini golf course is going to have a farm theme with a fake gravel path a windmill, a barn, and a drawbridge. Here is my design:

Our goal

Our goal is to make a fully functional golf course with some moving obstacles as well. We wish to have a windmill, a drawbridge and a barn. We want to code parts of our golf course with the LEGO MINDSTORMS coding software. We are going to code our wind mill and drawbridge.

Obstacles

This is our windmill, it’s our first piece of the mini golf course. We used Lego Technic to create the structure and covered it with cardboard right now it is not in a box but will be soon. The windmill has four small blades and a medium motor to power it. It has small legs that hold it upright so it doesn’t fall and the blades don’t hit the wood when it stands alone.

 

The next part of the build is a drawbridge. the main part of the drawbridge is that it has no walls making it a little bit harder but we may add wall later when we test it if it’s to hard. The bridge has a Lego Technic frame and a wooden base. The bridge is made a draw bridge because of the large motor winding a piece of string and pulling the drawbridge up and down on a three second loop.

Now the barn, we have done the walls and decorated them as well as making a roof and decorating that too. We think that our barn is looking how we want it to look but the bottom of it isn’t even so we will have to figure that out as well. I helped by cutting out the wood and hot glueing it together. Leon and Angus helped by cutting and printing out the decorations for the barn and glueing them on.

Why our obstacles are important:

The draw bridge and river.

The drawbridge was added because I personally think that more mini golf courses should have different obstacles. The drawbridge will probably be the hardest obstacle because it might have no walls meaning that the ball can fall onto the fake water and you have to try again. none of the other groups have a bridge or a draw bridge so it is a unique idea.

The barn.

We think that the barn feature is a big part of our design because we have a farm theme. I think a barn is a traditional farm icon and every good farm has a barn, right? We haven’t started the barn yet, but we are planning on making a classic barn with red walls and a white roof with little windows near the top on both sides. We are planning on building it out of wood but might use cardboard as well.

The windmill.

The windmill is our most classic feature because it is a well known mini golf obstacle. We thought that it would be easy to build but we were wrong. The code was easy but building it is hard because we couldn’t figure out how to get all four blades to point out. After a little while of rummaging around in the back room we found a little cog that had four holes. Then we connected the arms to the four holes in the cog and attached the blades and we have added supports for the Lego brick as well.

The order of the obstacles.

We decided that we should put the obstacles in a literal order putting the drawbridge first because is acts like a driveway over a river to the barn and maybe even a small house off to the side for decoration then the windmill as you get deeper into the farm and then the finish. The reason we only have three obstacles is because we only have a small space to work with.

Decorations

We haven’t talked about decoration yet but I’ll list some ideas here:

  • small house off to the side
  • little animals in paddocks
  • hills next to the track and a valley also
  • grassland
  • trees
  • flag at the finish
  • fake gravel and grass paths

Final reflection

I feel that our golf course is going mostly to plan and is looking how we want it to look. The golf course is coming along nicely it has dirt in one paddock and a rock wall around the course and the obstacles. Some of our challenges were the drawbridge because we couldn’t figure out whether to put a lego technic base or a wooden base because a lego technic base had holes in it and a wooden base wouldn’t fit well. We solved this problem by putting a lego base on the bottom and some wood on top to make it smooth, then voila we have a smooth sturdy bridge. Something we worked well on was the windmill because we all had a little part in building it, leon got the blades to point out, I got the motor to point out the side of the brick and reinforce the windmill, Angus helped make the legs and he helped code it too. We have all enjoyed this project a lot because it has been a rollercoaster of ups and downs and all of us like building and making things so we have really enjoyed this term’s designs project.

Lego EV3 project (both)

Archie Morgan and I were building a snowplough and here is five photos from all angles. Archie and I were also with Leon when we built the snowplough.

Our next project was a crane which we are still building. Here are are some photos from that project.

 

What Worked Well

Some things that worked well with the snowplough were the tank tracks for wheels as they would grip the carpet and it would move along with quite a lot of speed.

Things that worked well with the crane was the frame work and the arm i just found the arm on the ground and put a few more long pieces on the end and it fit perfectly so the next day i brought string to school and attached it.

 

What Didn’t Work Well

Things that didn’t work well with the snowplough were the grab and lift and getting it attached to the front of the block and the code. At the time we were using scratch and we found it unreliable so we tried different things but all to no good use.

Things that didn’t work well with the crane were the lifting mechanism and the motor to do so

 

What I learnt

With the snow plough I learnt that the tanks tracks were not good at moving on tables instead they were better on the carpet. I also learnt how to code with the lego ev3 software and how to make a robot follow a line using that software.

 

How could I use what I’ve learnt in the future.

In the future I could program more complicated robots and machines. I could help program other peoples robots if they were struggling.

The History of Australia’s Prime Ministers

Makey Makey Design Project:

I am working on a project with Leon. The project we are working on is a project about the prime minsters of Australia.

Our Design:

We are going to design a cardboard box with the past Prime Ministers names glued onto the outside. We will attach a small piece of foil below each of the names so when you touch the foil it will react with the Makey Makey and follow the code. Here is a photo of my design:

The Code:

We coded the Makey Makey to play prerecorded information about each Prime Minister when you touch the foil.

What You Will Learn:

When you touch the foil you will learn when each prime minister served and also when and where the were born for example:

Malcolm Turnbull: Malcolm Turnbull was the Prime Minister of Australia from 2015 to 2018. He was born on the 24 of October 1954 in Sydney.

 

Progress Photos

Here are some photos of our project:

       

Our Goal

Our goal is to make a black box with the names of the past 6 prime ministers on it and when you touch the foil it will say some information about each prime minister. on the sides and back of the box there are drawings that Leon and I drew

 

Our Struggles

Some of our struggles were:

  • getting the alligator clips to attach to the foil
  • the volume
  • getting the code to react

How we solved it

We solved getting the alligator clips to attach to the foil by sticky-taping the clips to the foil in a way that it would still conduct electricity and react

We solved the volume problem by bringing a speaker and putting it inside the box
