Rube Goldberg

we had made our first rube Goldberg machine with test groups just to see what it was like the purpose of the machine was to get paper in the bin it took us a bit to fine out what we were going to do but then we did and in the end what it did was rolled down a pipe which caused it to hit another ball which rolled over and hit the paper in the bin.

Simple machines

Lego simple machine

one of our simple machines was a Lego design it was all lots of fun I worked with my friend and we made a machine that makes potential energy.

Knex simple machine

so with knex we made a elevator it had a pully it was a great experience especially because we got to make a elevator and see what bits and pieces  an elevator needs

pully simple machine

so basically what we did is made a pully a pully is a simple machine that can be used to weigh something or transfer an object in height.

Rube Goldberg machine

Today we started planning our Rube Goldberg machine our materials are paper, golf ball, marble, 3 books, pully, card board and a ruler.

the prepose of the machine is just to open a book. It was good to get all our ideas done because we worked as a team and tried to combined all our ideas.

the simple machines we used was a pully, inclined plane and wheel and axle lever.

the materials we used was two cups, strings and soft wire for the pully. 3 books 2 books to make a inclined plane and the one book for when the machine has to open the book. and a ruler for the lever. cardboard to guide the marble to the ground.

 

 

 

 

 

 

 

 

 

 

robot questions

What is a robot: A robot is a machine made or controlled to do something that people can’t do or can do but just makes it more easy for the world.

What is needed to make a robot work: To make a robot work you need some sort of energy to charge it. Or a battery so you don’t have to constantly have to keep on charging it. And you also need a program to tell it to do something.

What is a program: is a place to go when you want to instruct a robot or something that takes instructions. A program is also a thing that instructs a certain thing by code.

Why do you think people invented robots: I think people invented robots to make tasks easier. Or because robots were invented to do tasks that humans can’t do.

robotics

Today what we did was made a robot which by the way was a great experience. It was my first time actually building a robot. The whole thing was a great success and a pretty simple task. I thought it would be hard. But then again I have never built a robot before so don’t blame me. It wasn’t the people I exactly chose but then I realized you don’t need your friends in a group  with you. Because you won’t work as well. That is why I think I worked well and didn’t get distracted. But besides that it was all fun.

we were working on a specific type of code it is called psuocode. It can be used to program a robot what we did was went on micro worlds and used the psudocode to move the turtle around. And then eventually we had to do the initials of our name which was had but easy at the same time. Because my initials are AS but it was good knowing how to use psudocode.

 

We had a purpose today and it was to focus on a table in our classroom.  What we did is made a program for our robot there was one challenge we had to do and in that challenge we had 3 tasks to which were degrees seconds and rotations . Here is a video on it.

Today we had a second challenge to do and that was to go around a baseball diamond. I tried that challenge and I was pretty successful. really the only  bit about it was that you had to get the 90 degree turns right.

 

today we were focusing on a attachment to our robot called a light sensor and our task for it was to make it so that when it sees a different colour than white it stops and does something else.

 

I was working on the ultrasonic sensor it was a very unique sensor to work a use I did not no most of the things that you could use on the ultrasonic sensor.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

rube Goldberg

Rube Goldberg was born on July the 4th 1883 and he died December the 7th 1970.

He lived in San Francisco, California United States with his Jewish parents Max and Hannah (Cohen).

He was the third of seven children born which three of them died as children. As young as four, Rube Goldberg began to trace illustrations and took up drawing lessons at the age of eleven.

Rube’s occupation included Engineering, sculpting, author, news reporting, inventor and a cartoonist.

He had many achievements over his career, in 1948 he was awarded a Pulitzer Prize for his political cartooning and in 1959 he won the Banshee’s Silver Lady Award.

Rube Goldberg became famous and was best known for his illustration’s of an over engineered invention that was meant to preform a simples task like the Rube Goldberg Door Opener Upper.

Here is a link to a video on it.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

A Rube Goldberg machine always has a purpose to do something it is all about creating a machine that uses a chain reaction to accomplish a very complicated manner.

 

 

 

 

friction tests

. Question: My question is which surface has the least amount of friction.

. We will change: The surface.

. We will observe: How the car travels.

. We will keep the same: Car, force and wheels.

 

All the information is on the pictures but besides all that testing out all the surfaces with our car was a brilliant experience.  

The grass on the oval had I lot of friction. But the bumpy quad had the most friction. The gym though was very slippery so had barley any friction. the carpet wasn’t slippery  but did still have barley any friction it was the surface that made our car go the furthest.

 

 

 

 

glossary

congruente

the word means same in every way.

 

obtuse angle

means greater than a quarter tur.

 

acute angle

means less than a quarter turn.

 

reflex angle

means less than half a turn.

 

adjacent

means sides that are next to each other.

 

parallel

means lines that are opposite each other that will never touch.

 

opposite

if you are referring to a shape it means sides that are facing each other.

 

working with craft power

Today the 20th of march we made racing carts personally Ferrari is the best it was an exiting and hard challenge it was a excellent experience soring and as well as hammering nails into wood I had enjoyable moments especially when it is so satisfying.here are some working pictures.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cereal Box Marble Run

3/2/17

Cereal box project [session one]

Today we made a cereal box marble run way with 30cm of masking tape cereal box and for the tracks left over cardboard from the cereal box.

I got my inspiration from youtube.com I first went to my table and started making my cereal box marble run way

hope you liked my first cereal box marble run I made it out of 30cm of tape and left over cereal box

cardboard

here is my second marble run same resources personally I think this one is better I thought really hard just because it was a two way marble run hope you enjoy 🙂

and that is the complaisant.

Thank you for watching hope you enjoyed it.

rollercoaster

  Session one

Friday the 24/02/2017

What we did today is designed a draft of a rollercoaster. And explained how it works and why it worked, also how it got around the obstacles. my rollercoaster  had two little hills to gather momentum and speed. To get around the loop I made that joins to a strait line.

probably as we make our rollercoaster I will change, take and add some stuff and obstacles.

Here is some progress over the two sessions.

 session 5

Our first  design was to big and not portable so we started from scratch. The second design was a much smaller version that was portable. It had up and down hills and a jump to another tube that was attached to a sideways loop.

 

session 6

So today we completely had a different idea we crabbed a random big box a put a couple of holes in it and a couple of tubes through the holes some tubes were made into a loop and one hill.

session 7

So today we were a bit off task but when we worked on the rollercoaster at lunch we got a lot done . Which was a great relief because we didn’t get in trouble. But I will say that in the last few days that we have really changed our design by far. But it was a great experience doing all this for the first time.

Session 8

Today we just finished our rollercoaster and felt so happy and relieved that we got it done. So then we joined it to another group which went well and the end result was amazing. There was x2 loops corkscrews and a spiral to me it was mind blowing .

 

Session 9

So today we had a major problem with our loop on our rollercoaster. The tube on the loop was squashed. So what we did is had to take off the cable tie that was squishing it. And every time before we put a marble in we have to squeeze the loop to even it out. Then we can put the marble in. After all that we had a huge success with everything nothing went wrong  even with the other team we joined our rollercoaster to they had no problem and when we got it working every time we were so excited.
