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 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.
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.
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 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.
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
- flag at the finish
- fake gravel and grass paths
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.
