Audio Booths was fun hear is a video to explain about it
here are photos
the Rob Goldberg machine was very fun and challenging the best thing was having fun with my friends and it finally worked and I understanding what did and didn’t work and that you need Sarton picas for it to work now we can set it up when ever we want to and it shod work I am looking forward to year 6 and the challenges’ to her is a video of Rob Goldberg machine working
for design I am doing rob Goldberg machine with George and Ben these are photos of the Rob Goldberg machine
this is the design of the Goldberg machine
this is the start were the car goes down
this is the part were the car hits the marble
this is were the marble and goes down the tube
this is the tube were the marble goes down and lands in the cardboard tube
this is a video of the first attempt
it did not work
so instead of using so much dominos we put track for the pingpong ball
me George and Ollie used the servo motor and this is the Exercise
This script is supposed to move the servo motor repeatedly to two different angles, but there is a problem. Try out this script, and figure out how to correct it.
this is a video of it working
I was sick for the entire week for this task so I am not certain what was meant to happen with this task,,,, sorry!
In this robotics challenge we had 5 challenges. One of them was a challenge to make the robot go in a square, which was a metre by metre, making the robot go a metre and reverse back a metre and using second, degree and rotations. It was really hard making the robot go in a square because it keeps on turning too far and too short but at the end it was really exciting.
I quite enjoyed this and learnt that angles are important and if you do it not enough or too much or if the robot is not aligned exactly right at the beginning then it will not work.
In this challenge, you are supposed to make the EV3 robot go around a black line on a humoungous oval. We had to use the right program otherwise it would not work and we thought it was very tricky to stay on the line as it would go off the line and then it would stop. It needed to be programmed to go back on the oval. It took me several goes to complete it.
It was fun and frustrating as it would not complete the whole oval as every single time it would curve off the oval!! It was very hard to get it to go in the oval shape. To make it work, we needed to use a switch block – a very specific program that is on the picture in my student planner. If it isn’t set up correctly it will not work. The switch block works by sensing colours – if it sensed black, it would keep on going around the circle, but if it sensed white, it would turn in slightly, to keep itself on track.
For robotics the project was line following we had to make the robot to go to the red piece of paper and go back to the start for that you need a colour sensor. this is s series of pictures screen snip of what does a colour sensor does
Steps are seen below
A colour sensor brick is used if you want to program a robot. you need to a start button and down blow there are buttons and you pick one of them and they all do different things – some make noises and turn. the colour sensor one looks like a timer but if you press this button it can compare colours and then you can change the colour that the colour sensor will stop on.
It was hard making the robot go onto the piece of paper but move off it without stopping. It took a few tries. It was really tricky but it was fun
