What we had to do today was use the ev3 programming app to use the touch sensor. The touch sensor bump into things but then program it to do something else after that. Our goal is to get the robot to go forwards then turn and go back. The other challenge was to get the robot to bump the wall and then turn around and go forwards.
In todays challenge we had to build a nothing part for our robot. What we built was a colour sensor. What it does is when it finds a certain colour it stops and then it does whatever you have programmed it to do. Our goal was to make the robot move to each colours in any pattern. The colours we used were blue, yellow, green and red. I have achieved making it do first go from the green to the yellow but I haven’t got it to go to the red or blue.
In maths today we got to play a maths game. The maths game was to see how much fractions that we had coloured in. This is a video explaining what fractions I had:
We also did another colour in fraction sheet. So the video explains what I did:
I have learned how to add the fractions together quicker then I could normally do.
Today in maths we are learning about shapes and using setpos. Setpos means that you move your turtle without having a line there.
I had to get some help from some people because I could not get the right amount to do the shape.
These photos explain what are goal was and how we did our geometrical shapes:
Today in class we started our Rube Goldberg Machines. What we had to do was plan what we were going to do. Our aim is to make a lolly fall into somebody’s hand. In it we have a pulley, a balancing beam, ramp, k-nex structure, books, dominoes and of cause a lolly. Our first plan was to attach the pulley onto a fan so that it would be able to hang down and work. We then changed the pulley on the fan. This was so that it would then be portable. We changed it by building a k-nex structure so it has a hook on the pulley which is attached to the k-nex structure. At the beginning of our RGM it has the ramp. We push the marble down the ramp which hits some dominoes. The dominoes fall into the pulley, one side of the pulley hits down on the ground the other side flies straight up hitting the beam on the other side of it. There is a marble in it so when the beam falls down onto the table the marble then hits the lolly into the persons hand.
Today we stated to program our robots. On our laptops we had to use Lego Mindstorms Education EV3 to make something and put it onto our robots. When we tried to put our program on our robot we couldn’t get it to work. We had to ask someone else to help us fix it. The problem was that on our program it was on the wrong plugs so we couldn’t make it work. When he put it to the right plug. We could then see what our robot could do.
Today we watched a video on the floor. We had to count how many simple machines there was in the video. Then we got a number. That number tells us what instruction book we get. Then we got started. When we got our instructions up we then tried to find the pieces to build that step. Once we started to find the pieces and get all the steps right we then got a marble and try to get it to roll down our creation. When we had our first test it did not work because the bucket was not hitting the marble down the ramp.
Today we had to build a pulley. A pulley is like a lift it has a pulley in it to make it move up and down. We used a plastic wheel, string, scissors, a hook, instructions , whole puncher and a cup. Once we got the materials we had to start to build the pulley. To start it off we had to put two holes on the cup.. Then we had to cut a piece of string to put in between the holes on the cup. The string was also connect to the plastic wheel. The wheel had a hook attached to it. After that we started to hang them up on a pin and move it up and down.
Today we had to build something out of k-nex. We decided to build a carousal. We had to find the pieces and to know how many we needed. I thought it was quite difficult because the instructions didn’t have any clear text to say exactly, how to build the certain pieces together.
