 Hello to our show on Rocking Robots. These are Legos and we're going to talk today about how Legos have gone from this to something that moves and you can tell it what to do. And with me today are a teacher from St. Andrew's schools, Devi Shintaku, and two of her students and they will help to talk about how Legos have gone from this to robots. So welcome to the show. Thank you for having us. Thank you. Thanks. So I showed you this. Now when I was a kid this is what Legos were and we were so excited when you had roof tiles. I don't know if any of you remember these. And then it went to having wheels and we were even more excited when we had things like this beams and axles and gears and things that connect this way. Now this is I think what gives these new Legos so much ability to be built in different ways. So the Technix bricks are part of the Lego family and if you get the robot, the EV3 kit it comes with a bunch of these pieces. So you don't get a Lego robot right off the back you get a box full of stuff. So I'd like to invite the kids maybe Maya if you can start just tell us a little bit about what's in the box. Are there like connectors or beams you can stand up and okay no okay we'll set it down right there and you can point at it. In the box you have everything you need to build the robot and some of the other gears like axles and connectors and there's also stuff you may use like beams and some gears. Yeah okay what's this thing? These are the wheels for the robot and the Lego EVC brick. Cool and then can you tell our viewers what are these just in general. These are some of the motors and like sensors that you can use. Wow so there are all these different pieces that come with the kit. What's this thing? This is the battery. And I guess it goes with the charger okay I guess that one right. So those are the pieces Aiden would you like to tell us what that can be turned into? Don't move too far but here it can be turned into a robot of different variations. You can build it into different robots. This is one robot that we built. Wow so it doesn't always have to look like that? Yeah it doesn't always need to look like this. It can look like different things. It comes with some different models that you can put together but you can even make your own so you don't even have to stick with whatever they suggest. Yeah yeah so that's a big difference from this I think that was one thing we wanted to to talk about. So if you can have a have a seat again then we can talk about what this can do. So would you like to put there's a button on top Aiden sorry if you can go ahead and wake it up. So what does the red light mean? The red light means it's either turning on or turning off. Okay so I think if we can take a look at some of the graphics that were put together maybe slide number two next. So this is the kit and everything that it comes with all the motors, the sensors and and all of that and oh that's here do you want to show them the sensor? You want to tell them what some of these are? Okay so yeah we're just going to move this out of the way okay and I think the next graphic can talk about how. Okay there's. Tell them what this is. This is the driving base where like it's powered from. It's kind of the standard model that the basic model that you can put together. There are instructions that come with it and so you follow it it's very easy to follow and they put this they put these together themselves just by following the instructions. Okay so let me get this the pieces out of the way and we can go ahead and talk about what the programmers are interested in hearing. They hear robotics and they think wow there's there's something that moves right. So how do you make it move Maya? So on the robot it should have like a small rectangular shape screen and buttons on the side the top and bottom are for choosing the program going up and down and the two other arrows are for picking which like window you want to go to. Okay look at the slide that shows the programs on there I think the next slide Maya maybe you can explain what these blocks are. These blocks are like ones that will show what is happening and what it's going to do. They're command blocks so each of those blocks tells it to do something so what does the first block? The first block if you hover over it's called move steering and if you click on it under it it should have like off on degrees rotations or seconds and right now it's on rotations. So would you see this graphic on the EV3 or do you need a laptop computer to do this? You need a laptop. Oh okay so you have a bigger screen to work with okay that's that's good. I think if we go to the next slide it has the actual what the screen looks like so when you're programming Maya why don't you explain the screen. So on the top right is like somewhere where you can put all the like steps and the first one is your name and the date and the next two is moving forward through rotations and moving back through rotations. So what's a rotation? What's rotating? Rotating is when the wheel on the robot moves like one rotation one 360 degrees around. Aiden maybe you can show us on the wheels how you know it's gone around one time. There is little claw like things on the wheels and if it goes from pointing straight up and it goes around one turn that will be how you know it's gone about 360 degrees. Yeah so what's this other what's this other? This is the arm that it goes up and it cannot go 360 though because that would be going through the robot. Yeah that would not be a good idea. You want to run some of these maybe the move forward program that we just saw. Okay how far is it going to go? We don't want it to run off the table maybe we should go sideways. The move forward is going to go that one. Oh you said they don't want it moving maybe you should lift it up and then they can just watch the wheels move. This one? Yeah. Yeah it did exactly three rotations forward and back. You can show them the arm one also if you want. Maybe turn it sideways so they can see it go up and down. Oh I saw that. So we did that this morning and Maya noticed that it was going really fast up and down. So what was your what did we do after that? So before we put it at power 50% and after we did half so 25. So you can control the power the speed of the motor cool. So how many motors do you have on this robot if I hold it? Did Aiden answer that question? Sure. There are three motors two to power these two bigger wheels they're right here and here the bigger sections are right here and then there's one medium smaller motor I'm not sure if you can see it but it's right here. So is there a limit to how many motors you can put on that brick? I don't think so as long as you have enough motors and a place to attach it to hang it on there. So I notice each motor has something coming out of it this cable and it plugs into one of those. The brick. Those cables. Yeah they're cables connecting the motors to the brick and on the laptop some of them say like C and B for the moves steering and C and B are connected to these two wheels to like move it somewhere and A is connected to the medium motor. So I noticed when it went the program said move forward and back so you can make it go straight. Can it turn? Yes. Is that something you would program? Yes I think we have a slide for that. Oh hey. Oh we also have a program. Oh here it is. So slide six there we go. You want to explain that one Maya? Yeah this one is turning 50 percent to the right which is a 90 degree turn and it's going at 50 percent power so not too fast and one rotation. Okay so it would move about four inches. Do we have permission from the control room there to move for the robot to roll four inches? It's just going to turn to the right. Okay. And one wheel will stay. Oh move that I would get that stuff. Yeah there we go. Hey. Okay cool. So you guys programmed that? Yes we did. Yeah awesome. So when you have a chance to put the programs together on the laptop how do they get here to the actual robot? Oh Aiden. Aiden. Aiden is a long cord. Can you show it? Yeah. Alright cable. I think I saw it. The download cable. Yeah it plugs into a. One is a USB. USB C area whole thing right here. And then the other side is a USB. So it plugs into the robot and then this is a USB cable cord thing that plugs into a laptop. Yeah okay. So you program it and then you send the command. Send the command to the robot and it downloads very quickly. And then you unplug it and you can test your program. Cool. So do you want to show some of the other programs? We have some graphics. So this screen is what it looks like when you're on the computer. And oh tell them what's at the bottom of the screen on the left side Aiden. Maybe you can explain those little. Those little blocks are. You tap on there the commands that you sent to the robot basically. And you click on them and drag them up to that triangle block. And then you can press on those numbers to program however far or whichever way you want your robot to go. Okay so a graphical way to do the programming. So you still have to figure out what the steps are and what each motor does. But you're telling it using this program. Now we're going to take a one minute break. So we'll be back. See you soon. And Aloha. And Aloha my name is Calvin Griffin the host of Hawaii in Uniform. And every Friday at 11 o'clock here on Think Tech Hawaii we bring in the latest in what's happening within the military community. And we also invite all your response to things that's happening here. Those of you who haven't seen the program before again we invite your participation. We're here to give information not disinformation and we always enjoy response from the public. But join us here Hawaii in Uniform Fridays 11 a.m. here on Think Tech Hawaii. Aloha. Hey Stan the energy man here on Think Tech Hawaii. And they won't let me do political commentary so I'm stuck doing energy stuff. But I really like energy stuff so I'm going to keep on doing it. Every Friday on Stan the energy man at lunchtime at noon on my lunch hour. We're going to talk about everything energy especially if it begins with the word hydrogen. We're going to definitely be talking about it. We'll talk about how we can make Hawaii cleaner. How we can make the world a better place. Just basically save the planet. Even Miss America can't even talk about stuff like that anymore. We got it nailed down here. So we'll see you on Friday at noon with Stan the energy man. Aloha. I am Howard Wigg. I am the proud host of Cold Green for Think Tech Hawaii. I appear every other Monday at three and I have really really exciting guests on the exciting topic of energy efficiency. Hope to see you there. Aloha. My name is Mark Shklav. I am the host of Think Tech Hawaii's Law Across the Sea. Law Across the Sea is on Think Tech Hawaii every other Monday at 11 a.m. Please join me where my guests talk about law topics and ideas and music and Hawaii Anna all across the sea from Hawaii and back again. Aloha. Welcome back to our Robots Rock Show with St. Andrew's Schools teacher Debbie Shintaku and two students Maya and Aiden. Thanks again guys for being here. So we've been talking about the EV3 robot which is built from Lego parts and programmed on a laptop computer. And after they figure out what they want the robot to do they connect it via a cable and the robot does it. So we've done forward and back we've done a little bit of a turn but it does it did a little more right. Yes there's another turn that they did the another slide that you could we could show go to the next one. And Maya can you explain what this one does. This one is a 180 turn to the left. And if you want it to go to the right you do not negative and to the left is negative. So where does the robot end up. Maybe Aiden can show us what 108 at 180 degree turn would be. So they're selecting which program to run and then they hit the start button. It turns half of a 360 spin. I'll run it again and it should turn about a full 360. And that's what a 180 turn looks like. Very good. So how about the next one. That went so well. Go ahead and show the next slide please. Maya you want to explain this one. This block is called a weight block and it will wait a few seconds depending on how long you want on one of these choices. And for us we chose just time. So there are a lot of other sensors you can have it wait till the ultrasonic sensor senses something a certain distance away. We haven't gotten into that yet but there's there are a lot of different choices there on waiting and have a loop and doing different things. So you can tell it to go somewhere wait a second. So if you push something really hard and it has to bounce before the next step you calculate that in and just have it sit there. Okay cool. So what else do you have on here. Let's see what was the next slide there. So go ahead and go to the next slide. Oh this is the move you asked about the arm this is the moving arm up and down so let's see maybe Maya can explain that. So this one is the media motor and it will just turn to the right or the left. But if you have another gear and put it perpendicular to it then it can make it turn up and down. So notice what is controlling it. You mentioned about the motors earlier about the ports to use which one do you use for the motor the media motor. You use port A. Aiden do you want to demonstrate that for us of where that is. Port A is right here it may be blocked by some cables or my hand. And you just need to make sure that what when you're writing the program what has to match. The ports the letters and it has to match on your program. If we look at that slide again and we look at that slide that it says on the top right corner there's letters. So this media motor the cable connects to here which is the motor and it connects to port A so. So will it work if your cable for the media motor with this program was in port D. No because then it would not do anything. Since nothing is in port D. Or port A you mean. Right port A as the program says port A you're right. Okay. Do we want to demonstrate that one again. Oh okay. The arm one. Okay the arm one yes. Oh okay. And then it waits two seconds and then it does it again just a bit slower. I think there was another slide on that that showed the actual. Oh this is what the program looks like. Wow so something it seems so simple actually has a lot of pieces to it. What are those blocks above the those little boxes above the blocks command blocks. What are they for. So those blocks above the program box are called common boxes. So like if someone else is looking over your work or you forgot what you're doing. It's already up there typed so you know what you are going to do and what those blocks are going to do. Cool. All right. So have we gone through the programs that you were ready to demonstrate today. Yes that's all that we have here today. So I wanted to ask a little bit about what you might be able to do with a robot that you can command. So something you can do with it is there's this first Lego league and there's like challenges that the robot needs to accomplish. And we're doing that this year. Cool. Do you know what the topic theme of the challenges are. I think it was into orbit for like problems in space. Yeah exactly. So I would like to congratulate you all for being part of a team this this year. It's your rookie year. The first year is always the hardest because you have to learn the programming. You have to learn the building putting all the pieces together. And then you have the project researching some topic. And this year it's into orbit. Yeah. So the project is researching a problem that they might encounter in space and either physical or social problem. So they've worked together and chosen a topic which by the way this is our first co-ed team that we've done or activity that we've done. So the boys and girls are working together. Usually they are separate in the schools at St. Andrews. There's the prep for the boys and the priority for the girls. But in this venture we are working together and learning to work as a team. Excellent. Yeah. So what do you have on the schedule for next week? Do you know what the. We have classes Monday, Tuesday, Wednesday, Thursday and sometimes Friday. You mean the team meets. Yeah. The team meetings. The four school and at lunch. Excellent. So I think we have only about a minute left. So before we end I just wanted to ask if there was one thing you wanted to leave with the audience. Maybe we can start with you. Well that robots, there's a lot that you can do with robots and the age that bringing it down to fourth grade and I think that's. I previously have taught students that were like some of their eighth grade and but doing the same types of things. It's really amazing how well they are learning as was just demonstrated today. Thanks. Maya? I just think that Lego robotics is fun and very interesting. Thank you. Hayden? I think that you should have fun when doing robotics. Okay. Yeah. I think that actually this adventure of coming to the studio and having green screen behind and then seeing what it looks like when it's finally produced is hopefully kind of fun. To add to your experience. Yes. And thank you for watching and for sharing with us this journey on robots rock. Thank you.
