Session 1 (I have not been able to add screen snips and videos in yet)
Today we started doing a new challenge in robotics where we have to follow a black line using the colour sensor. I found it challenging when the ev3 wouldn’t stay on the black line and it would go off the side. I have learnt how to make my ev3 use the colour sensor to follow things from doing this session.
I have completed the program for my ev3s line challenge and now I am making my ev3 search for the black line and then follow it, I have learnt how to use a new programming tool called repeat. the most challenging thing in this challenge was actually when my ev3 found the black line, it needed to follow it.
I have started on a new program that the teacher said we needed to do where the ev3 follows a black line in a oval shape on a board until the ev3 ran out of power. once again I needed to use the repeat brick to make it constantly follow the line and make it so that cords are in the right slots of the brick. I have discovered that my program doesn’t work as well on the out side of the black oval as it does on the inside.
Today we started Scratch in design and were told to make a account which includes your own nickname, a password and your email. Next we were given a tutorial on how to make a sprite dance, I chose to get a polar bear sprite off the already made sprite section because he has different costumes for dancing. My background was a snowy area. I learnt how to switch costumes to make him dance.
Scratch is a game making software on the computer that we are using in robotics.
There are these things called sprites they can either be objects or players that you can design, programs are used to control the sprites.
this is my first time ever using scratch and its awesome!
Because I missed the first session that the class did, this makes this my first session.
I have started on a little project to learn how to use the programs this is a snip of it.
in this session I have started on my first game called Asteroid.
Most of you have probably heard it.
Here is a screen cast of me talking about the program of the game so far.
to make the o in my initials I would have to get in to a space where I would have space for the w and also have room so I don’t go out of the lines. I am currently working on making the w but I have finished the o.
Shapes in 4 different corners.
Here is the Cartesian plane that I made to show the 4 different corners for each shape. I have made the square which goes in the top right corner and the triangle which goes in the top left corner and then the circle ( which I got off my o from the previous session ) in the bottom right corner and then the rhombus in the bottom left corner.
Session 1 (Pulleys)
The first session with Mr McKie and the pulleys we had to choose a partner to work with to create the pulleys. We used wire, string, yogurt containers, scisscors, marbles and the pulleys. I noticed half way through the more pulleys you have the lighter it is to pull it up.
Session 2 (Knex)
The second session of simple machines with Mr Colbert, we were in groups of 4 and had to make a Knex carousel. It was similar to LEGO but the pieces were harder to put together and all the pieces are different. I found that It was complicated to put together. I discovered that connecting the pieces in different stages was much easier.
Session 3 (LEGO)
The third session we made LEGO chain reactions creations. This time we were in groups of three and we had to make a marble roller. Once we finshed the marble roller we connected with another group and created a mini Rube Goldberg machine.
Today we were put into groups of 3 and told to make a basic design of a Rube Goldberg creation. I started off by sketching the design and what the simple machines in the design could do.
We found it hard because one of our group members was sick and not at school today. We had to think of ideas by our self and not have their opinion. We put together some ideas and will include Zeph when he gets back.
Today our group member was still sick sadly. We needed to keep going so we managed to finished our design and started using fine liner to go over it to make it stand out. We also needed to work out who was bringing the materials in. Again we needed to make these decisions without Zeph, but we had to keep the project moving . We will be able to include him when he returns and think of things he can do also.
Our group member, Zeph is finally back! We ran through every thing with him and by the end of the session they were complete and we created our first simple machine the pulley!
We have changed the pulley design. We had to do this because the pulley wasn’t high enough. We sticky taped it on to the cardboard tube to make the pulley the same height as the tube. Meanwhile, we created the spinning object from our design which was made so the marble would hit the spinning object and make another marble go and knock over something. The spinning object is at the end so then we can get that out of the way.
We built up a stronger support to make sure the first one doesn’t fall down. we also created a new pulley system so that the cups go up and down smoother.
Session 6 part 1
Today we learned about kites and the angles. here is a video that my partner and i made.
Today we were put in to groups of three and were given the BRICK which is pretty much the brain of the robots. The robot required cables, the BRICK, motors, wheels and Lego pieces.
In this session of robotics each group was told to make a detailed drawing of the robot itself and what the parts do. (haven’t received the photos yet) as you can see I made a birds eye view angle and a side angle drawing to show the brick and the robot.
Today was the last session of drawing. I finished my drawing and started programming the robot. I simply just made it go forward and back first but now I have added sound which I thought was pretty cool.
Today we were told to make a program using seconds, rotations and degrees to go forward. These are my programs.
Seconds Program.Rotation’s Program.
Session 5 (for me)
Today I’m finally back! My group have equipped our robot with a colour sensor, the colour searches for colours and once it scans say your hand it will go the opposite way if you have the right program.
Session 6 (for me)
we have a colour sensor
What is a robot?
A robot is a complex factory made piece of technology that can do some jobs that humans can’t do, they don’t need food or water and a holiday
They don’t have a brain so you have to program them to do things.
What is needed to make a robot work?
Moving parts and also a program to make those moving parts move.
Why do you think people invented robots
Because humans needed something that they can’t do, and also they could of made them because they don’t need food or water and breaks because humans need those sorts of things.
What is a program
A program is a computer system that makes electronics work a program is also where you put words into commands that you have to make yourself. A program is a complex line of coding that will make a robot do something
You wont believe what happened today! They found my Mum. The only problem is the Burkes. That’s what is gunna be a challenge. Oh yeah, I’m seeing her next week.
I’m really stressed about what she is gunna think of me. I hope she likes me . I’m almost there if I end up staying with her then Sam’s bike will be mine!
I am writing to you while I am with my Mum. She is the nicest person i have ever met!
I can’t wait to begin spending the rest of my life with her.
