This week we learnt on how to use colour sensors. colour sensors are a feature that you can put on your robot to track colours. For example, our challenge was for our robot to stop when it hits a colour with either coasting or just a break. The difference between coasting and breaking is that coasting is the motor stops but with the remaining speed the wheels keep turning and breaking is simply stopping straight away. We struggled to do this challenge since we didn’t know the program so we asked Arnav to help us at first it didn’t really work but with Arnav helping we managed to get it to work.
We also did a challenge with looping. Looping is where you have to make your program run through again as many times as you want instead of making a REALLY long program that just repeats a command OVER and OVER and OVER again. The challenge was to make your robot go around a piece of paper WITHOUT any contact with the paper, and you HAVE to use loops. Here’s a video! ( Video Coming Later… )
This week we started using a sensor! We started using a touch sensor, so that if our robot bumped into something it would go back and try and go a different way. It started off really hard because when we put the sensor in the program and it wasn’t moving so we asked Mrs Malone and she helped us, but then our sensor didn’t work. Whenever it crashed it didn’t stop. So we decide to switch sensors. After we did that it started to work! I really enjoyed this experience and I think we can use the sensors in future programs!
We had trouble with the last challenge but where really proud of ourselves. This weeks challenge is display blocks. display blocks are an option in the programming section of making the robot. you can make your robots screen flash with some words for seconds, you can pick how long you want. I really want Bud to be able to tell us a story. And that is exactly what where planning! It’s really fun to be able to have our robot say things to us and others. We can use this information that we learnt in this week if we want to use the display block feature again in another program. We worked together well this week and it was really fun to play with the display blocks This is what the story says.
Hello World. I’m bud and I’m going to tell you a story about how I was built. I started off as just a brick but now I’m so much more thanks to Mallory Zali and Sophie!
After the last challenge we moved onto a new one, the Turning challenge. The turning challenge is a challenge where you have to do two different types of turns with your robot a pivot turn and a spin turn. our group found the pivot turn quite easy but the spin turn was really hard for us. As hard as we tried our robot, Bud always never faced the way he had started. We started looking through the other things Mrs. Malone emailed us, and we found one that said ‘How do we turn 90 degrees?’ and we saw it said to use port view. We all thought it was worth a try so Sophie started on port view and spun Bud around. we got the number which was 765 it worked the first time and it worked but when we tested it again with the same number it didn’t work, so we tried 800 and 780 then we found the number that worked it was 755. We where so proud of ourselves for persisting and figuring it out. The first turn in the video is the spin turn and the second turn is the pivot turn.
The challenge this week was port view. Port view is an option on our brick where we can measure the degrees of getting our robot to different spaces. The way you measure it is not very complicated, you have to go into port view, try and get your robot to zero degrees ( or whatever way you want to measure with ) and push the robot along he ground to your selected area ( don’t push to hard ) your robot will straight away start counting. when you get to your selected area take the robot off the ground and the number should be right there. all you have to do then, is start up a program and click on what option your using ( Like degrees ) and write in the number that showed up on your robot. Our group had a good time doing this challenge, it was fun to try out port view.
Sophie, Mallory and I built our first Lego robot in the first week on Friday its was very hard and challenging but we got to programming in the end. We named our robot Bud, though we couldn’t change the actual name of the robot because the option wasn’t there on the ‘Brick’ which is the area where you send the messages to make your robot do commands. we worked together well and had fun building and programming it.
we continued to program our robot that we built last week, right now I really want our robot to be able to go to a specific spot and then come back to us. we did really well with building the robot and playing our roles in doing it. I didn’t see any patterns in what we did but we all got a turn at taking the photos and videos. I can use this knowledge again if we do more projects with the robots or other teamwork requiring things. It was important to learn about programming because if I want to do it in the future I have got some knowledge about it. We built a robot whole showing great teamwork and we helped each other if we got stuck. The moving straight challenge consisted of using degrees, rotations and seconds to get your robot from a start line to a finish line. It was quite hard to do all three and it definitely required a lot of thinking and planning but we eventually got our robot to do all of them!
