Scratch Term 3

We e k   o n e

This week the sprites just wouldn’t stop dancing and we wouldn’t stop programing. we learnt how to make or add music and make character.

Here is the link to my screen cast explaining what my sprite does and how i programed it.

Week two

This week we where focusing on a very challenging challenge, which was the 10 brick challenge. Basically what this is we are only limited to 10 blocks you can use those blocks multiple times but you are restricted to using any other bricks. here is the link to my screen cast explaining what it does and why i used those bricks.

Week three

This week we got to explore see what other creators where up to this is a game i found that i would hope to or to do  make a similar one.

 

Week four

In today‚Äôs session we focused on ‚ÄėParallel Programming‚Äô. This is basically when you have more then one sprite and they interacted with¬†each other or to do something at the same time. I found the most helpful brick was the¬†‘if¬†touching ___ then’ because then if it touches the other sprite (interacting) then it could say move etc.

Here is a screencast showcasing what my script does and how it interacts.

Build a band

In today‚Äôs session we created and explored¬†‚ÄėBuild-A-Band‚Äô. This is simply a program that you can make play and sing along to. My program works by a menu and you choose a number next to the song you want to listen to, when that number is pressed on your keyboard it will come up with a photo of the artist. I was surprised I could make this program so simple.

sewing

This week I and 9 others had the opportunity to have a week of sewing.¬†I have had some experience with sewing at home and at¬†the last choice day. With experience¬†I got to show and help others, this help me with my learning too.¬†Yet again¬†I had some experience with making mobiles, if you don’t know what mobiles are they are just items or shapes hanging from a string, for an example here is an image (this is not my work).

This image is slightly different to mine because mine is in a straight line.

Sewing machines are a lot more difficult then they look i would have trouble with getting the cotton jammed.

Here is a design explaining some stitches and what they are used for there is also a practise mobile.

 

Here is an image of my final copy I am really happy with how this turned out i love the colour combination and the shape i chose. I used a  straight stitch which is explained on my scan above.

BLACK LINE CHALLENGE

W e e k  1

In design we have been focusing on the colour sensor, we had to make the robot follow a black line. The challenge was it can start from any where find the line and follow it.

this is a scanned copy from my design book explaining what each brick is about and how I programed this.


 

this is the video to my program working on a straight line as you may notice in the video when the colour sensor (the light) sees white it turns one way and when it sees black it turns the other.

 

here is the link to my video on the big oval.

to large to fit on blog movie maker is not working so i will be showing soon!

 

week 2

At sewing

 

w e e k   3 + 4

Our next challenge was to do the exact same thing but add a touch sensor which stops when its touched mine worked with the exact same program with an added touch sensor and stop.

here’s my program.

as you can see it is quite similar to my other line following programs but with an additional touch sensor block.

click here to watch my line follow and touch in action.

Next I hope to use my touch sensor but it gets touched it turns around and goes back.

Scratch

This week we where introduced to a new program called scratch. Scratch is an app installed on your laptop  that you can create games or moving pictures you can create yourself. We did this by programing, we had some experience because of the EV3 robots. I found this was a little easier because the bricks where written out and they where clear on what the brick was about.

We where given 7 scratch tutorials to help up start our journey. I and I imagine many others found the tutorials very helpful. These tutorials included how to create a sprite which is a character, programing your sprite to move around and how to program a few games that may help you create new ones. some of the games where a racing game, a maze, fruit ninja and a couple more.

 

 

 

 

Micro Worlds

In maths this term we have been focusing on the program micro worlds.

I find micro worlds is helpful for degrees and angles. This program allows you to have a small black turtle and experiment with making any shape or squiggly line you want.

We think of this turtle as a robot so we speak code words

Forward 100- fd 100 (the number depends on how far you want to travel)

Left turn 90- lt 90 (the number depends on how far you want to turn)

Right turn 180- rt 90 (the number depends on how far you want to turn)

Pen down- pd (this allows the turtle to draw)

Normally we a set a task and today we had to draw/make the initials of our name, because my name starts with¬† a “C” I just have to do a semi circle. Now if you can make a full circle with the demands¬†“repeat 360 [fd 1 rt 1]” then just half it and because a full circle is 360 that would be 180, so now I tried this demand “repeat 180 [fd 1 rt 1]”. this formed a “C” shape.

Robot Questions

What is a Robot?

A robot is a self-operating machine that can complete things that you would normally do yourself but now is done by a machine. Robots can be made with metal, plastic and all sorts of materials. Robots can be used for many different tasks like  tasks that are too dangerous for humans to do or things that are very time consuming or repetitive.

What is needed to make a robot work?

What is a program?

The main part of the robot is what it does and to make the robot actually work you need a program. A program is a series of specific instructions computer chip, you can give instructions and if you connect it to your machine, it will make it work.

Why do you think people invented robots?

I think Robots where invented for many different purposes like lifting heavy objects, heart and brain surgery’s and even space exploration. These can be so helpful for humans in need the environment and just for everyday tasks we don’t even know we are using robots like most people will vacuum and do the washing every day these tasks are actually done by robots.

Robotics

Session 1- Pseudocode and Robot build

This week we were introduced to our new unit, robotics I cant wait to see what’s up next because most of these robots we make are made out of Lego and I love Lego. When we where buiding our first machines I found that you really do need to follow the instruction’s very carefully because we had to start¬†one side again just because we did only one step wrong.¬†I cant wait to see more challenges ahead.

Session 2-

This session was a mini session so we are not completing a Rube Goldberg machine we were making things that could be helpful for our machines and this session we were working with lego.¬† This was kind of like a Rube Goldberg machine because it is a long series of events but it does not complete a simple task. We where split up into groups of 2-3 and each group was set a different part of the big machine and at the end we will join then together to make an awesome machine. my group did the section with all the ramps this was a challenge and in the end we did complete the Lego structure but when we try to make it work so I’m not sure if it was us or the Lego building.

Session 3-

This session was another mini session and the things I learnt in this session is definetly going to travel with me till the end of the year today we where buliding awesome simple machines out of knex so my group decided to make a carousal the instructions where kind of confusing to read but in the end it did work and this is because the handle was attached to two wheels with ridges on them so when the connect they spin.                                                           

Session 4-

This session was our final mini session and we where creating pulleys we need these materials

Wire-

String-

A wheel?-

And something to hang it off we used a door handle-

Every time we made a new pulley we would have to add a wheel I’m not to sure if this made a difference but it definitely got harder as we went along.

When we wanted to use it we simply just pulled a string here’s a video.

Session 5-

I was so excited for this session because we where finally getting back to our robots we where a bit behind the other groups because we had to start some of it again and there was this one piece that just didn’t seem to appear anywhere but finally we found it.

Soon enough we did finish and we where pretty proud.

This session we also started to design and this time we where only drawing our EV3 robots but we had to make sure it had all the detail and it was labelled. we also had to think hard and see what part what make the robot work.

 

Session 6-

This session we started to program I found this quite hard because we weren’t really told what the buttons did until the end so first we just had a play around. Then the challenges started to roll in we had to completes the task of our EV3 robot go to a finish line and back to the start. I found it¬†was most helpful to use two modes: speed and duration because it does really depend on these because we need to have the right speed but if the speed is to fast for the time/duration then it probably won’t make it to the finish line. But realised these where only modes for seconds we had to complete that task three way seconds, degrees and rotation. Personally I thought degrees was the hardest because you had to get all the angles in the right spot. after finishing this challenge headed right to another one.

-A SMOOTH SEA WILL NEVER MAKE A SKILLFUL SAILOR-

Session 7-

Another challenge, today we have been working on the newest challenge. The task was to make our EV3 robot go around baseball diamond or in our case four rulers taped together.¬†First trying it¬†out I used degrees¬†at a 45 degree angle this would go of on a curved line and it wouldn’t be a sharp right turn so I tried it again but with a 50 degree angle, somehow this seem to work¬†better. I didn’t get to try it with the rulers yet so I hope to soon.

WHAT’S NEXT

Next session I hope to try my program on the rulers and change slight parts if needed.

-CHALLENGES IS WHAT MAKES LIFE INTERESTING OVERCOMING THEM IS WHAT MAKES THEM MEANINGFUL-

Session 8-

This session I have been working on my baseball diamond, today I tried it with the rulers and it is just not getting all the perfect angles and timing.

-RUNNING AWAY FROM ANY PROBLEM ONLY INCREASES THE DISSTANCE FROM THE SOLUTION THE EASIEST WAY TO ESCAPE THE PROBLEM IS TO SOLVE IT-

Session 9-

This session we are using a new mode called a sensor now you might of heard of a sensor before, sensors will reacted to something when it moves, when it sees a colour on a surface or something around but many other different things. In our case we are using colour. For our first attempted it only went to the colour green (the coloured paper on table) this is because we wanted it to work when we add more. I found it quite hard to program this at first but realising what I can achieve but also what the buttons do I could help people but I could also learn from my peers.

-IF IT DOESNT CHALLENGE YOU IT DOESNT CHANGE YOU-

Rube Goldberg

This week our task was to create a Rube Goldberg machine which is a difficult series of events to complete a simple task and our task was to put a piece of rubbish in the bin. In this machine we had to use three simple machines and ours where a ramp, pulley and a lever.

         pulley                                                lever

                                                                                                                                             ramp

The reason we have a thicker pole on a thinner pole is because then it will spin and make the pulley work.

 

There is a piece of paper scrunch up in the ramp which is also made out of paper and so when the pole spins it makes the rubbish role down¬†the ramp and into the bin. When we failed most times it was because the ball didn’t go in the bucket/pulley or the paper didn’t go in the bin and it would go off the edge off the ramp.

After completing this project I realised how hard this is going to be but its not going to work if we cant make mistakes.

Session 2-

This session was a mini session so we were not completing a Rube Goldberg machine we where making things the we could use in our machine and be helpful and this session we where working with Lego. This kind of like a rube Goldberg machine because it is a long series of events but it does not complete a simple task. This was in parts so we split up into groups and each built a part of the machine we built the part with the ramps.

This was very difficult and we did achive to make the structure but when we tested it out it would always fail this was a challenge and we don’t know if it was the machine or we just didn’t know how to work it.

Session 3-

This session was also a mini session and this session was super helpful and I will definitely be using this for my rube Goldberg machine and this mini session we where creating knex structures.

Session 4-

This session we where finishing our simple machines, structures and Lego machines.

Session 5-

This session I couldn’t wait to get started because we finally are doing the rube Goldberg machines. Starting my design was quite hard without an idea so my group brainstormed what our machine could do or complete. We finally decided on playing music from a laptop. From all the help from the mini sessions and practise machine, thinking of an idea of how this is to work was not to much of a problem.¬†This machine is quite similar to my practice machine but¬†obviously different because its a different task and if I did the same I wouldn’t be learning anything.

Session 6 & 7-

I bet this was the part we were all waiting for… BUILDING! And from the very first moment we started to build I know challenges weren’t my enemy, I will fight the challenges and obstacles¬†I will do what ever it takes to make this an amazing experience.

We had to include 3 or more simple machines so we chose an incline plane, lever and also a pulley.

INCLINE PLANE

An incline plane is basically just a technical word for ramp and for this we will be using a clear plastic tube and supported by the pulley.

 

PULLEY

I decided with some knowledge of pulleys from mini session and practice machine maybe we could include one of those methods in our rube Goldberg machine.

 

“DONT LIMIT YOUR CHALLENGES

CHALLENGE YOUR LIMITS”

Session 8-

This session we continued to build hard work¬†is definitely something that we faced. This session we were focusing on our pulley we tried the way like I did in he practice machines, I don’t know what was different but for some reason the pulley wasn’t turning to well, I was thinking it was the thicker pole on top because it wasn’t actually to thick so next session¬†my group will definitely trying to make this pulley turn better.

WHATS NEXT  

My group hope to achieve next session the pulley to work and spin better but also try to add our incline plane.

WE DONT GROW WHEN THINGS ARE EASY, WE GROW WHEN WE FACE CHALLENGES

Session 9-

as we hoped this session we fixed our pulley we did this by adding a bigger cardboard pole on top, we also added tape around the string so it wouldn’t slide and instead of the string moving it would be the pole.

TIN CANS?

Yes you might be wondering why would you would put tin cans on the chair, well the reason is because we where originally going to change our pulley and use them instead so that is also why we have string attached. Soon realising that why come so far but then just change it so instead we are using it to stabilise our pulley.

RAMP

Today the part that took the most attempts was the ramp made out of rulers and I think this is because there is a jump between the pulley and the ramp so it has to be in the right spot for it to work.

LEGO PLATFORM

So this little colourful block of lego is to hold a little marble, it is set off by the thicker pole on the pulley turning.

WHATS NEXT?

Next session we hope to add a clear tube for the marble to run through.

IF YOU CAN DREAM IT YOU CAN DO IT – Walt Disney

Session 10-

This session we did add the clear tube this took a long time to set up because the weight of the tube pulled down the pole and the marble would run straight through the tube without even moving the pulley. If the marble that went through just went straight to the spacebar it wouldn’t be to much of a entertaining machine and we wouldn’t learn from that.

WHAT NEXT

We are hoping to make the marble hit something like dominoes or a ball we are not to sure yet. but doing this means we will have to re-design.

Investigating Friction

Question:

What surface has the most amount of friction?

We Will Change:

The surface so we can see what has the best friction and is best for the car to travel on.

We Will Keep the Same:

The weight, wheels and car because if we did change it then this would affect the way it travels on that surface.

Findings:

I have found out even though there are bumpy surfaces doesn’t mean they don’t have any friction or they don’t go far the bumpy quad travelled the furthest at 4.90 and the oval at 4.46 the bark in the playground I wasn’t surprised¬†I went only one meter because the bark would get in the way.

The bumpier the surface the more friction there will be because the object and surface rub together to slow it down.
